Title: Defroster for refrigeration cycle
Inventor: KASHIMA MASAO
IPC: F25B5/00
Filed: 1978-02-02
Abstract: PURPOSE: To prevent the capacity of defrosting and cooling from falling, by causing an evaporator to perform a cooling run while defrosting another evaporator by hot gas and by conducting a part of the hot gas to a low pressure section when the pressure of a high pressure section has fallen.  
     CONSTITUTION: When an evaporator 10 is defrosted, a soleniod valve 12 is closed and a hot gas solenoid valve 18 is opened to conduct a part of the hot gas from a compressor 1 to the evaporator 10 through a bypass pipe 17 and branch pipe 20 to defrost the evaporator. The part of the hot gas subsequently flows into a liquid receiver 5 through a solenoid valve 8. The other part of the coolant from the compressor 1 is introduced into the other evaporator 11 through a condensor 2, a pressure-reducing valve 4 and the liquid receiver 5 to constitute a refrigeration cycle. A soleniod valve 24 is opened by the action of a pressure detector 25 and a part of the hot gas from the compressor 1 is introduced from a conduit 22 into another conduit 23 in order to prevent the pressure of the high pressure section from falling when the hot gas is branched into the bypass pipe 17.

Title: Semiconductor laser element
Inventor: MAEI SHIGEKI
IPC: H01S5/16
Filed: 1985-01-23
Abstract: PURPOSE:To inhibit the gains of a higher transverse mode even when the groove width of a window region is not narrowed, and to form a semiconductor laser element enabling fundamental transverse mode oscillation by forming a higher- mode absorption region having a groove width narrower than that of the window region between a curved oscillation region in an active layer and the flat window region in the active layer. CONSTITUTION:A semiconductor laser element oscillates by low threshold currents because an active layer 34 is curved in an oscillation region L3, beams do not dissipate because there is also a waveguide in a window region L1, and there are beam waists in the vicinity of resonator end surfaces 41, 42. Consequently, the deterioration of the resonator end surfaces 41, 42 can be prevented, and the breaking outputs of the resonator end surfaces 41, 42 can be increased. There is also a higher-mode absorption region L2 between the oscillation region L3 and the window region L1, and the laser element is oscillated stably at a fundamental transverse mode up to high optical outputs in order to positively inhibit higher transverse mode gains.

Filed: 1979-02-06
Abstract: PURPOSE: To prevent oil-lock in an oil-cooled type rotary compressor by providing a switch valve in a piping connecting the suction side of the compressor and a separator tank and opening it for a preset period at the starting time and limiting the supply of oil to the compression unit.  
     CONSTITUTION: Air drawn from suction port 4 is compressed in compressor proper 1 and is sent to separator tank 2 via discharge pipe 5. Lubricant 7 in separator tank 2 is sent, by the pressure inside the tank, to the compression unit 6 of compressor proper 1 via lubricant supply path 8. At the time when the compressor is stopped, since pressure exist inside of separator tank 2, if air inside of separator tank 2 is caused to escape into suction pipe 3 by opening valve 10 at the starting time, lubricant 7 is not supplied in a large amount to the compression unit 6 of compressor proper 1. Consequently, it is possible to prevent oil-lock in the compressor.
