    Abstract: PURPOSE:To enable a large heat-resistance material and a sample such as a cooling structure to be heated for achieving an evaluation test by allowing a high-temperature high-speed gas to be discharged by receiving supply of a fuel and an oxidizer and this gas flow to be directed toward the sample. CONSTITUTION:A high-temperature high-speed gas is generated by allowing a fuel f to be combusted in a combustion equipment 10 and a gas flow is accelerated in a nozzle 11, thus forming a field of a high-temperature high-speed gas flow h. Then, a heat-resistance material, a sample 12 in cooling structure, etc., are installed within the field of this flow h and is heated, thus enabling them to be evaluated. Since this structure is based on a rocket-engine structure. a flow rate of a high-temperature gas can be set to a high level. thus enabling a test device to be large, especially an exit diameter of the nozzle 11 to be large. This increase in size allows a field of a large gas flow h to be formed, thus enabling the large heat-resistance material and the sample such as a cooling structure to be heated and evaluation test to be performed.

    Abstract: PURPOSE:To manufacture a gradated functional material having different property at the front and the back by heating the surface of a powder green compact with laser beam after heating it near to starting temp. of sintering, cooling the back face and sintering while giving temp. gradation. CONSTITUTION:For example, the powder green compact W composed of ceramic on the front face and metal on the back face, is set on a cooling device 25 in a sintering furnace 13 and the inner part of the furnace is made to an inert gas atmosphere with a vacuum suction device 18 and gas introducing hole 19. Successively, after uniformly heating in the sintering furnace 13 near to the starting temp. of sintering to the powder green compact W with an electric heating device 11, the powder green compact W is irradiated with the laser beam in a laser beam heating device 22 through a laser beam irradiating aperture 21 to heat the surface thereof. Simultaneously, cooling gas is supplied from a cooling device 25 to cool the back face of powder green compact W, and the sintering is executed under the condition of existence of the temp. inclination between the front and the back. By this method, as coming from the front face to the back face, the gradated functional material continuously varying the property at atomic and molecular level, is obtd.

    Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of thermoelectric conversion characteristics caused by sublimation and oxidation, etc., of an element in PbTe, for example and attain stable thermoelectric conversion for a long period by crowning at least a high temperature side end part of a thermo-element with a conductive block having a recessed part in which the end part is force-fitted. SOLUTION: Since edge parts 1H and 1L of a thermo-element 1 are crowned with a conductive block 3, the end part can be electrically and thermally combined to other parts by the conductive block 3. The thermo-element 1 and the conductive block 3 are combined by force-fitting a thermo-element end part to the recessed part 1 of the conductive block 3. Since there is a possibility of generation of a gap between a thermo-element and a conductive block microscopically, generation of heat shearing stress can be avoided even if the high temperature side end part 1H is subjected to high temperature heating. Furthermore, it is possible to avoid generation of sublimation and oxidation of a constituent element of the thermo-element 1 and prevent variation of an element and deterioration of characteristics.

    Abstract: PURPOSE:To make it possible to utilize energy from a moon power station on the ground, by converting the generated energy from the moon power station into an ultraviolet laser and converting the ultraviolet laser into an infrared laser at a space base and converting the infrared laser into a power at a ground base. CONSTITUTION:A solar light power station or a nuclear power station 3 is installed on the surface of the moon 2. A satellite 4 as a relay base can be relayed to a receiving base 5 on the ground. An ultraviolet laser 6 is used between the moon 2 and the satellite 4, and an infrared laser 7 is used between the satellite 4 and the ground base 5. That is, the ultraviolet laser 6 is converted into the infrared laser 7 by the satellite 4, and the infrared laser 7 is transmitted to the ground base 5. In the ground base 5, the infrared laser 7 is converted into a power by a photoelectric converter made of P/1/N, and the power is transmitted to necessary places. Thus, an energy from the solar light power station or the nuclear power station 3 installed on the surface of the moon 2 can be utilized on the ground.
