Filed: 1992-08-05
Abstract: PURPOSE:To obtain a high frequency fusing device for heat fusing material which applies high frequency power to load efficiently by providing a compensate means for compensating change of electrostatic capacity at electrode section based on movement of fusion electrodes. CONSTITUTION:An auxiliary negative electrode 7 is provided on a shaft 4 and an auxiliary positive electrode 8 is provided at a positive electrode 1.

Abstract: PURPOSE:To improve the cooling efficiency and miniaturize a cooler by providing a plurality of pipes communicating with the outside of an external enclosure in which a semiconductor pellet is contained, and sealing therein a refrigerant performing phase changes in boiling and condensation. CONSTITUTION:First, a pellet 10 is pressurized to a proper value owing to the deformation of a buffer part 16 of an external enclosure 13 once copper blocks 14, 14 undergo load in the arrow direction from the outside. Then, as power is supplied through the copper blocks 14, 14 the pellet 10 is heated, and produced heat is transmitted to the copper blocks 14, 14. Thereupon, a refrigerant 17 in contact with the surface outer periphery of the copper block 14 is boiled and evaporated. Evaporated vapor is sent from a vapor paper 18 of the external enclosure 13 to a heat exchanger, and is liquefied, and is thereafter returned from a return pipe 19. More specifically, the pellet 10 is directly cooled by the cooling system. Accordingly, thermal resistance is reduced compared with a prior art system where heat is once transmitted to the outside of the external enclosure, and further since a cooler is integrated, the entire can be miniaturized and made light-weight.
