摘要： PURPOSE:To improve effectiveness and reduce cost by using ceramics having the main component of aluminum nitride as an insulation body. CONSTITUTION:Semiconductors 1 and 2 of a n type and a p type are connected and fixed in electrically series and thermally parallel with pure Cu plates 3a and 3b. AlN plates 4 and 5, in which a Cu pattern having the same shape as plates 3a and 3b is formed by a metalization method, are joined via lower temperature solder. A thermoelement is formed with such a pair of the semiconductors 1 and 2, plates 3a and 3b, and plates 4 and 5 as an insulation body. Electric power can be obtained by giving a temperature difference to the thermoelement, on the other hand, a temperature difference is produced by flowing electric current. A compound of Bi and Te, a compound of Bi and Sb, and others are used as a thermoelectric substance. Ceramics, having the main component of AlN and the additive of Y2O3 of 0.5-5.0wt.%, are preferable as an insulation body, and are formed by hotpressing raw material.

摘要： PURPOSE:To heat a material to be heated in a crucible to a high temp. and to increase the heating energy efficiency of the heater by providing an electron collector constituting an electron impact means and an electron gun as a cathode for emitting an electron beam in a vessel. CONSTITUTION:The electron collector 4 and electron gun 9 arranged in the vacuum vessel 1 are connected in series through a high-voltage DC power source 15. A material 2 to be heated such as Nb is charged into the crucible 3 made of calcia, etc. The electric terminal 4 and the electron collector is brought into contact with the material 2 in the crucible 3, and the material 2 is heated by the impact of the electron beam from the electron gun 9. A thermoelectron is emitted from the material 2 heated to a high temp., the thermoelectron flows into the electron collector 4 to secure a current passage, and the electron-impact heating is continued. By this method, heating is carried out with high heat efficiency by using the electrical insulating crucible.

摘要： PURPOSE:To improve the efficiency of a thermoelectric element when it is used at a low temperature by forming different conductive materials of a conduc tive material and a superconducting material other than it. CONSTITUTION:A Bi-Sb alloy containing 12% of atomic ratio of Sb is employed as one branch 1 of a thermoelectric cooling element, and YBCO superconducting ceramics like a composition of Y0.9Eu0.1Ba2Cu3O7-delta are employed as the other branch 2. High purity copper is employed as a conductor 3 of low temperature side, high purity copper is also employed as the material of conductor and liquid nitrogen cooling boxes 4, 5 of high temperature side, and a thermoelectric cooling element is formed of a junction of low temperature solder. According to such a thermoelectric element, in comparison with that using no superconduc tor as the material of one branch, a large temperature difference is obtained in case of heating and cooling, and large power is obtained in case of generating power.

摘要： PURPOSE:To suppress rise of the temperature even in the case that a reflex surface receives intense light irradiation by setting the reflection factor in the visible light region and the emissivity in the infrared region to the respective specific values in the surface area other than the reflex surface. CONSTITUTION:The whole or a part of the surface other than the reflex surface to reflect light is formed from a substance in the condition that the reflection factor in the visible light region with wavelength 0.4-0.7mum is over 0.7 and that the emissivity in the infrared region with wavelength 3-10mum is over 0.7. An example of the substance having such a characteristics of emissivity is preferably ceramic, and Al2O3, MgO, or SiO2 or any composite oxide consisting of two or more of these, which satisfies this heat radiation characteristic, and is suitable as a substance to constitute a surface. Thereby, the mirror is obtained in which temp. rise is slight even when it is exposed to strong light as well as solar radiation.
