    A novel engine geometry, which is named provisionally as "basement and radial configuration", was proposed and investigated in this paper. The geometry gives a vibration-free and kinematic energy fluctuation-free property to motions of plural parts; i.e. pistons. A single radial arm rotor drives all the moving pistons in this configuration. In this study, a prototype three-cylinder internal combustion engine based on the geometry was designed and manufactured. The specifications of the prototype engine are as follows: the number of cylinders of 3, a piston displacement of 21cc x 3, a cylinder bore of 30 mm, a piston stroke of 30 mm, a compression ratio of 4.9, propane as fuel, a valve system of a rotary valve. A trial operation of the prototype engine resulted in the achievement of firing operation (8.1W output at 311 rpm) without any support of electrical motor and so on. This paper gives the pressure variations in the three combustion chambers on the firing condition. The theory and design for a compact 2nd prototype engine were reported. Especially the detailed design of the mechanism of crankshaft rotation, which consists of main-crankshaft, sub-crankshafts, split needle bearings, and a radial arm rotor, has also been provided.

    Robot systems capable of experiencing remote environments are urgently required for future lack of manpower and aging society. In this study, the development of the tele-existence robot arm system in which human beings can experience not only the haptic environment but also the thermal (hot/cold) environment was focused on. In this system, operator's shoulder and arm should be restricted by an exoskelton wearable device to get motion and posture information of a remote robot arm. For development of a proper wearable device, it is important to design the configuration of joints of the wearable device so as to allow every motions and postures of an operator without any interruption. Especially, a shoulder joint of human is so functional that the reproduction by a simple mechanical structure has been almost difficult. In this report, prototype design of a wearable arm device, originated from collar bone joint, with a novel (111) isometric shoulder configuration, was introduced.

    Robot systems capable of experiencing remote environments are urgently required for future lack of manpower and aging society. In this study, the development of the tele-existence robot arm in which human beings can experience not only the haptic environment but also the thermal (hot/cold) environment was focused on. In this report, the temperature transmission system was actually developed, and the trial operations were conducted. In the operations, a remote finger-tip-like temperature measuring unit touching a moderately (50degC)-heated test block (aluminum) transmitted a PWM signal of a temperature variation to an on-site wearable unit. Consequently, the reproduction of the remote temperature sensing data was succeeded by controlled heating based on the transmitted information in the wearable unit. In this paper, first, the reproducibility was indicated by the result of the positive(hot) temperature variation of the temperature measurement unit of the on-site finger probe in the wearable unit. Second, comparison between reproductivities of two types of thermal controll units of wearable device to generate a cold environment was made.

    Carbon Fiber Reinforced Plastic(CFRP) has been widely used in variety industries because of its high strength-density ratio. Therefore disposal method of waste CFRP should be considered in advance now. We have been proposed a combustion incineration of carbon fiber(CF) residue after recycle use. However, carbon fiber residue is almost impossible to be burned out by even high temperature burnt gas because of extremely high melting point of carbon fiber and a low oxygen concentration in burnt gases[1].
    In this study, self-sustained combustion of carbon fiber in oxygen has been reported. In order to obtain information of the self-sustaining mechanism of the combustion, in this paper, a convenient optical technique to acquire the 2D distribution of high surface temperature of glowing solid material was conducted.
    In this technique, magnified thermographic view of the high temperature specimen was provided by comparison between RGB brightness information of conventional photograph of the visible light emission of the surface and previously-calculated values from Planck's law and the spectral sensitivity of the camera system.
    In this paper, first, accuracy of the method was verified by comparison between the 2D temperature distribution result of a glowing fine (0.5 mm dia.) graphite rod in burnt gas of a propane-air premixed laminar flame and its estimated temperature distribution measured by PR-type thermocouple and compensated by Kaskan's method. Next magnified instantaneous 2D temperature diagnostics of self-burning carbon fiber bundle in oxygen was made. The 2D surface temperature distribution result gives very high temperature over 2900 K on carbon fiber surface in in-oxygen combustion incineration.

    Non-scanning 3D-CT(Computer Tomography) technique using a multi-directional quantitative schlieren system with flash light sources has been proposed to obtain instantaneous 3D density distributions of flames, supersonic jets and etc. This "Schlieren 3D-CT" is based on (i) simultaneous acquisition of flash-light schlieren images taken from numerous directions, and (ii) 3D-CT reconstruction of the images by an appropriate CT algorithm. In this paper, accuracy of this technique is evaluated and verified by checking with a standard refractive index distribution of a helium jet. Next, the verified 3D distribution of refractive index of premixed flames are successfully converted to appropriate temperature distribution.

    Robot systems capable of experiencing remote environments are urgently required for future lack of manpower and aging society. In this study, development of the tele-existence robot arm in which human beings can experience not only the haptic environment but also the thermal environment was targeted. In this report, first, a tele-haptics robot arm system, driven by torque control, was introduced. Silicon rubber is used for the fingers of the robot arm because its thermal conductivity is close to that of human skin. In order to investigate the temperature rise caused by contact with a heating body, thermocouples were embedded at the depths of 0.3, 0.6 and 0.9 mm of the silicone rubber finger tips. Temperature measurement was carried out when a high temperature aluminum cylinder of 60 deg.C was touched with a heavy force of 7.8 N and a light force of 0.86 N. The results was compared with numerical simulated results.

    Using a delicate multi-directional quantitative schlieren optical system, the 20-directional observation of high-speed premixed turbulent flame, non-uniform density flow, by employing non-scanning 3D-CT (three-dimensional computer-tomography) technique has been conducted. The 3D density distributions data of target flame by using ML-EM (Maximum Likelihood-Expectation Maximization) an appropriate CT (computer-tomography) algorithm are successfully reconstructed. In the previous report, a novel technique "multi-path integration" is proposed for noise reduction in projections (density thickness) images of CT (computer-tomography). Multi-path integration is required schlieren brightness gradient in both horizontal (x-directional) and vertical (z-directional) directions, or in other words, in two orthogonal directions (e.g. horizontal and vertical or two perpendicular diagonal directions). The 20-directional quantitative schlieren optical system presents only images of schlieren brightness in the horizontal gradient (x-directional) and another 20-directional optical system seems necessary to obtain vertical (z-directional) schlieren brightness gradient, simultaneously. In the present investigation, the report deals with introducing a new technique for obtaining vertical schlieren brightness gradient from horizontal experimental data without the necessity of a new optical system. This new approach is a simple and inexpensive solution. First, for a deep understanding of complex schlieren brightness, a numerical simulation is performed. Next, the initial density thickness (Dt) images are obtained from images of schlieren brightness in the horizontal gradient (x-directional). Finally, using inverse process from density thickness (Dt) images, the vertical (z-directional) and diagonal schlieren brightness gradient data of target flame successfully obtained. The mentioned technique can be used for obtaining any optional directions of schlieren brightness gradient.

    The 20-directional observation of high-speed premixed turbulent flames, non-uniform density flow, by employing non-scanning 3D-CT (three-dimensional computer-tomography) technique using a delicate multi-directional quantitative schlieren system has been conducted. The 3D density distributions data of target flames by using ML-EM (Maximum Likelihood-Expectation Maximization) an appropriate CT algorithm are successfully reconstructed. First, the report deals with introducing a new approach for noise reduction in projections (density thickness) images of CT called "multi-path integration" novel technique. The numerical simulation results approve that the new approach is a good technique for noise reduction in projections images of CT. Next, by using inverse process for 3D density distributions data of high speed turbulent flame the 20-directional horizontal (x-directional) and vertical (z-directional) brightness gradient of schlieren images reconstructed. Then, by employing the new technique, the new set of projections images of density thickness successfully obtained. Finally, by using the new set of density thickness images "with decreased noise" as projections for CT reconstruction, the 3D density distributions data of target flame successfully reconstructed. The results validate that the "multi-directional integration" novel technique is a good technique for noise reduction in obtaining projections (density thickness) images of CT and the 3D density distributions of CT result.

    Measurement of instantaneous density distribution of the shock-cell structure of an underexpanded supersonic microjet escaping into an ambient space from an axisymmetric convergent-divergent (Laval) micro nozzle has been conducted. For 3D observation of supersonic microjet, non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light source is employed. In this technique, for simultaneous schlieren photography, the custom-made 20-directional schlieren camera has been constructed and used. This study examines underexpanded supersonic jet from a micro nozzle with nozzle pressure ratio (NPR) 5.0 and plenum chamber pressure (stagnation pressure) 0.505 MPa. This micro nozzle design Mach number is Md = 1.5 and has circular cross-section with an exit diameter of 1000μm. First, the report deals with the density distribution. The density contour plot data of the jet flow is obtained by 3D-CT (Three Dimensional Computer Tomography) reconstruction of the images by MLEM an appropriate CT algorithm. Next, the density distribution data is calculated by formula. Theoretical results based on the theory of Tam (1984) are found to compare favorably with experimental measurement. The measured and calculated results are in acceptable agreement.

    A novel rotational internal combustion engine is invented and investigated for APU(Auxiliary power unit) of aircrafts and range-extender-power-unit for electric automobiles. For the applications, IC engines are required vibration-free characteristics. In the present engine, no reciprocating component is used, resulting in vibration-free operation. This engine mainly consists of a rotor casing, a rotor and a crank shaft. The rotor shapes as single lobe peritrochoid (S.L.P.) curve. The rotor rotates by the crank shaft of eccentricity e and rotates itself in counter-direction by phasing gears. The rotor casing shape having two cavities is defined as envelope curve of the rotating single-lobe peritrochoid rotor. The room between the rotor and casing performs the working processes for working gas; intake, compression, ignition, expansion and exhaust processes. The intake of premixed gas of air and fuel and exhaust of burnt gas are controlled by rotary valves installed on the combustion recesses of the rotor-casing. The combustion recesses are equipped with spark-electrodes for ignition. One of advantages of this engine compared with Wankel rotary engines and a previous engine invented by authors, is easy and reliable sealing of working gas. In this engine configuration, that is, a sealing component is only installed on waist section of rotor-casing, instead of complex sealing system on a rotor in case of Wankel engines, resulting in high efficiency by low-leakage of working gas.
    In this paper, first, configuration and geometries of this engine are described. Next the prototype engine is introduced and the cyclic behavior of the working process of this prototype engine is explained. Performance of the prototype engine driven by an electric motor is also shown.

    Non-scanning 3D-CT(Computer Tomography) technique employing a multi-directional quantitative schlieren photographic system with flash light source, has been performed to obtain instantaneous density distributions of spark-ignited laminar / turbulent flame kernels. For simultaneous schlieren photography, the custom-made 20-directional schlieren camera was constructed and used. The flame kernels are made by spark ignition for a fuel-rich propane-air premixed gas (flow velocity :1.0 m/s, equivalence ratio :1.4 ). Spark electrodes of 0.4 mm diameter with 1.0 mm gap are used. First, development of laminar flame kernel is indicated in the 1st row high-speed image of top right. 3D printed model of the CT reconstruction result show the spherical shape of flame kernel with a pair of deep wrinkles. The wrinkle is considered to be caused by spark electrodes. Next turbulent flame kernel behind turbulence promoting grid is selected (trubulence intensity 0.26 m/s). Second row high-speed images of top-right show corrugated flame shape. 3D model of CT result expresses the instantaneous 3D turbulent flame kernel shapes. These 3D solid models are 3D-printed as 2 times large size for threshold density level of 0.7 kg/m3.

    For 3D observation of high speed flames, non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light source, is proposed for instantaneous density distribution of unsteady premixed flames. This "Schlieren 3D-CT" is based on (i)simultaneous acquisition of flash-light schlieren images taken from numerous directions, and (ii) 3D-CT reconstruction of the images by an appropriate CT algorithm. In this technique, for simultaneous schlieren photography, the custom-made 20-directional schlieren camera has been constructed and used. This camera consists of 20 optical systems of single-directional quantitative schlieren system. Each system is composed of two convex achromatic lenses of 50 mm in diameter and 300 mm in focal length, a light source unit, a schlieren stop of a vertical knife edge and a digital camera. The light unit has a flash (9 micro-sec duration) light source of a uniform luminance rectangular area of 1 mm x 1 mm. Both of the uniformity of the luminosity and the definite shape are essential for a quantitative schlieren observation. Sensitivity of the digital cameras are calibrated with a stepped neutral density filter. Target flames are located at the center of the camera. The image set of 20 directional schlieren images are processed as follows. First the schlieren picture brightness is shifted by no-flame-schlieren picture brightness in order to obtain the real schlieren brightness images. Second, brightness of these images is scaled by Gladstone-Dale constant of air. Finally, the scaled brightness is horizontally integrated to form "density thickness images", which can be used for CT reconstruction of density distribution. The density thickness images are used for CT reconstruction by MLEM (maximum likelihood-expectation maximization) CT-algorithm to obtain the 3D reconstruction of instantaneous density distribution. In this investigation, the "density thickness" projection images of 400(H) x 500(V) pixel (32.0 mm x 40.0 mm) are used for 3D-CT reconstruction to produce 3D data of 400(x) x 400(y) x 500(z) pixel (32.0 mm x 32.0 mm x 40.0 mm). The voxel size is 0.08 mm each direction. In this investigation, the target flame is spark-ignited flame kernels. The flame kernels are made by spark ignition for a fuel-rich propane-air premixed gas. First, laminar flow is selected as the premixed gas flow to establish the spherically expanding laminar flame. The CT reconstruction result show the spherical shape of flame kernel with a pair of deep wrinkles. The wrinkle is considered to be caused by spark electrodes. Next turbulent flows behind turbulence promoting grid is selected. The corrugated shape flame kernel is obtained. The schlieren 3D-CT measurements are made for the complicated kernels. CT results expresses the instantaneous 3D turbulent flame kernel shapes.

    In present study, in order to provide a suitable technique for 3D observation of high speed turbulent flames, non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light source, is proposed for instantaneous density distribution of unsteady premixed flames. This "Schlieren 3D-CT" is based on (i)simultaneous acquisition of flash-light schlieren images taken from numerous directions, and (ii) 3D-CT reconstruction of the images by an appropriate CT algorithm. For simultaneous schlieren photography, in this experiment, the custom-made 20-directional schlieren camera has been constructed and used. Target flames are located at the center of the camera. The image set of 20 directional schlieren images are processed by MLEM CT-algorithm to obtain the 3D reconstruction of instantaneous density distribution. In this investigation, the target turbulent flame is high-speed burner flames. The burner has a nozzle exit of 4.2 mm diameter. The average flow velocity of the propane-air mixture of equivalence ratio of 1.1 is set to be 4, 6, 8 and 10 m/s. The burner is equipped with a turbulence promoting orifice in the burner tube. In order to anchor the high-speed flame on the burner nozzle, the burner tip has 4 holes for introducing the pilot flames. Results of the 3D-reconstructions indicates that the distributions show the complicated shape of the high speed turbulent flames. It is also found that the flame structure of higher speed flame has fine scale corrugations. This corresponds to the "corrugated flamelets regime" of the Borghi & Peters diagram for premixed turbulent combustion well.
