Title: Refrigeration cycle device
Inventor: FUSHIMI KIMIO
IPC: F04B49/10
Filed: 1987-11-13
Abstract: PURPOSE: To ensure sufficient safety protection upon failure of a low pressure switch by interrupting operation of an inverter circuit when the low pressure of a refrigeration cycle drops abnormally below a set level with no action of a low pressure switch. CONSTITUTION: When the low pressure drops abnormally, a low pressure switch 8 opens to interrupt the conduction path to an inverter circuit 21. Consequently, operation of a compressor 1 is interrupted and abnormal drop of low pressure is suppressed thus protecting refrigeration cycle apparatus. The low pressure switch 8 is kept open except when it is operated manually to sustain interrupted state of the compressor 1. Upon failure of the low pressure switch 8, operation of the compressor 1 is sustained regardless of abnormal drop of low pressure. When the pressure Ps detected by a pressure sensor 10 drops below a set level Px due to progress of low pressure drop, a control section 23 interrupts operation of the inverter circuit 21. More specifically, operation of the compressor 1 is interrupted and further drop of low pressure is suppressed.

Title: Scroll compressor
Inventor: BABA TOSHIAKI
IPC: F04C29/04
Filed: 1985-12-20
Abstract: PURPOSE:To improve the efficiency of a scroll compressor by inserting a heat insulating material inside a groove formed in the panel board of a fixed scroll and preventing the temp. of a refrigerant gas sucked into a scroll part from rising. CONSTITUTION:A heat insulating material 19 is installed on the inside of the groove 18 of a fixed scroll 6. Part of refrigerant gas which has flowed into a suction chamber 11 through a suction pipe 12, flows directly into the D part shown in the figure, whereas, the other part flows into the C part through the groove 18 of the fixed scroll 6. The sucked-in refrigerant can flow into the C part without being directly brought into contact with the fixed scroll 6 in the groove part 18, due to the heat insulating material 19 which is installed inside the groove 18. As a result, the temp. of the refrigerant gas flowing into the C part can be prevented from rising since it is not subjected to heat exchange with the fixed scroll 6 the temp. of which has been raised by a discharge gas, thereby, preventing the lowering of energy consumption efficiency and a mechanical loss.

Abstract: PURPOSE:To contrive to increase a light output without making the aspect ratio of laser light by surrounding both sides of the stripe of a second clad layer processed into a stripe with a light-absorbing layer. CONSTITUTION:The multilayer film of n-GaAs buffer layer 2, n-(Al0.6Ga0.4)0.5In0.5 P clad layer 3, n-Al0.5In0.5P optical reflection layer 4, Ga0.5In0.5P active layer 5 and p-(Al0.3Ga0.7)0.5In0.5P light guide layer 6 is laminated on n-GaAs substrate 1 and p-Al0.69Ga0.31As clad layer 7 processed into a mesa shape and p-Ga0.5In0.5P cap layer 8 are formed on a the multilayer film. An n-GaAs current block layer 9 is accumulated on both sides of the layers 7, 8. Even if the mesa is widened to about 10mum or the light guide layer 6 is made somewhat thicker, a light passing the light guide layer can strongly feel the difference in refractive index from the block layer 9 to prevent the reduction of the active layer of the radiation light of a laser and that of a horizontal radiation angletheta11. When the width of the mesa in the vicinity of an end face is widened especially, it is possible to lower a light density in the end face and to manufacture a semiconductor laser resistant to light damage.

IPC: H02M5/45
Filed: 1991-11-06
Abstract: PURPOSE:To prevent overvoltage tripping due to excessive voltage on DC side of an inverter caused by power flowing into an inverter for compensating voltage distortion of sine wave power supply. CONSTITUTION:A feedback control system 16 receives a difference voltage EDF between an upper limit set value EDF(ref) of DC side voltage of inverter and a DC side voltage ED of a compensating voltage generating inverter, as a control input, when the DC side voltage ED of compensating voltage generating inverter exceeds the upper limit set value EDM(ref) of DC side voltage of inverter. The feedback control system 16 then performs incremental correction of the amplitude of a load voltage reference signal vL(ref) from a level corresponding to the rated value of power supply voltage thus equalizing the amplitude of corrected load voltage reference signal vLA(ref) to that of the basic wave component of a power supply voltage detection signal vS. Furthermore, a compensation voltage is produced from the compensation voltage generating inverter depending on the difference voltage between the corrected load voltage reference signal vLA(ref) and the power supply voltage detection signal vS.
