摘要： A closed type boiling cooling apparatus for cooling a heat generating member (10) by utilizing the latent heat of vaporization of a boiling refrigerant (8a) comprises a cooling vessel including an evaporator section (1) and a condenser section (3). A liquid refrigerant reservoir (6) is enclosed at its upper opening portion with an expansible member (7) and is connected with the cooling vessel by means of a condenser pipe (5). The cooling vessel and the condenser pipe (5) are filled with the boiling refrigerant (8a) when no cooling operation is performed. When cooling operation is initiated the boiling refrigerant (8a) is changed into gaseous state (8c) and then led into the condenser pipe (5) which serves to liquefy the gasified refrigerant (8a) and feed it into the liquid refrigerant reservoir (6). The expansible member (7) is adapted to expand in response to the change in the amount of the liquid refrigerant (8b) led into the reservoir (6) so that the internal pressure of the cooling vessel can be maintained substantially constant.

摘要： The liquid crystal cell (30) for the optical change-over switch comprises a pair of transparent substrates (l), a pair of transparent flat electrodes (2) provided on the respective opposing surfaces of the substrates, orientation control films (3) provided on the flat electrodes (2), two pair of comb shaped electrodes (33) respectively provided on the orientation control films (3), and a ferroelectric liquid crystal layer (4) confined between the substrates (l). The optical incidence plane (3l) to the cell (30) is so selected that the plane (3l) is away from the helical axes (9) of the ferroelectric liquid crystal in the cell (30) in the order of somewhat greater than the tilt angle ( ϑ t ) of the ferroelectric liquid crystal. The pair of flat electrodes (2) generate a first electric field (37a) perpendicular to the layer (32) and orient the long axes of the ferroelectric liquid crystal molecules into a first orientation (35a′) parallel to the layer (32) to induce a first refractive index which causes simultaneous reflection of unpolarized light beam (7 + 8) with a predetermined incidence angle ( ϑ ). The two pair of comb shaped electrodes (33) generate a second electric field (37b′) parallel to the layer and perpendicular to the helical axes (9) and orient the long axes of the molecules into a second orientation (35b′) not in parallel to the layer (32) to induce a second refractive index which causes simultaneous transmission of the unpolarized light beam (7 + 8) with the predetermined incidence angle ( ϑ ).

摘要： A boiling/cooling system for cooling a semiconductor element in use thereof has at least one cooling member (5) including an evaporating section (5a) containing a liquid refrigerant of high vaporizability sealed in it and a condensing section (5d) for cooling the liquid refrigerant from the evaporating section when it is heated and vaporized. The semiconductor element is clamped to the evaporating section. To avoid problems arising from the application of a high voltage to the cooling member, a highly thermally conductive insulating material (4) is interposed between the semiconductor element (1) and the evaporating section (5a) and clamped into position by a metal clamp (10). The evaporating and condensing sections can thus be in a unitary structure.
