Title: Air conditioner
Inventor: SHIMIZU KEIICHIRO
IPC: F25B13/00
Filed: 1990-09-05
Abstract: PURPOSE:To prevent fluctuations in capability or instability and maintain a liquid level under a proper condition by installing a refrigerant pump capable of changing over its transfer directions to an oil equalizing pipe communicated with a plurality of compressors respectively and providing an equalizer operation means which alternately carries out forward direction operation and reverse direction operation of the refrigerant pump. CONSTITUTION:A case of a compressor 1 is communicated with a case of a compressor 2 by way of an oil equalizing pipe 40 where a refrigerant oil 41 is installed to the oil equalizing pipe 40. The refrigerant pump 41 is capable of switching over its transfer direction to forward direction or reverse direction. When the refrigerant pump operates in forward direction mode, a flow passage is formed from the compressor 1 to the compressor 2 by way of the oil equalizing pipe 40 thereby equalizing the oil level in the compressors 1 and 2 and preventing oil rise or lock. It is, therefore, possible to prevent fluctuations in capability and protect the operation from instability as well.
Patent JP-H0285727-A (JP)
Title: Infrared detector
Inventor: TOKUDA HIROSHI
IPC: G01J1/02
Filed: 1988-09-22
Abstract: PURPOSE:To suppress noise caused by a change in air temperature and warm and cold air by providing a pair of pyroelectric elements and a window member partially provided with a thin film which does not transmit infrared rays. CONSTITUTION:When, for example, warm air collides with the front face of a window member 8, a uniform temperature change occurs in the plane of the window member 8 partially provided with a non-transmissive thin film 9, since the heat capacity of the film 9 is negligibly small as compared with that of the window member 8. As a result, the infrared energy reradiated from the member 8 is uniformly radiated from the entire surface in the plane and electrodes 2.1 and 2.2 which are paired pyroelectric elements are irradiated with infrared rays of the same energy density. Accordingly, the thermal fluctuation of this detector caused by the warm air is canceled by the pyroelectric element pair and not outputted. Moreover, infrared rays which are made incident on the front face of the window member 8 and radiated from an object to be detected are transmitted by the member 8 except the part where the film 9 is formed. Therefore, only the electrode 2.1 is irradiated with the infrared rays and are fetched as a signal output from a terminal.

Title: Gate circuit of gate turn-off thyristor
Inventor: KAWABATA SHIGEYUKI
IPC: H02M1/06
Filed: 1983-12-16
Abstract: PURPOSE:To increase a rate of rise of di/dt required for turning-off within an allowable range by using plural gate transformers connected in parallel in the output part of a turn-off gate circuit to reduce a leakage reactance while holding a dielectric strength well. CONSTITUTION:Two gate transformers 7a and 7b are used and are connected in parallel. Two gate transformers are connected in parallel in this manner to constitute the output part of the turn-off gate circuit, thereby reducing an equivalent leakage impedance of a gate rransformer circuit to a half. As the result, di/dt of a turn-off gate current and the peak value are increased, and the dielectric strength is held well. In case of a large-capacity GTO (for example, 2,500V and class 200A), 30-40A/mus is necessary for di/dt of the turn-off gate current, and a circuit which can realize easily this di/dt and is most suitable for the turn-off gate circuit of the large-capacity GTO is obtained.

IPC: B60L1/00
Filed: 1983-12-15
Abstract: PURPOSE:To eliminate an excess current between auxiliary power source circuits by stopping a current flowed from other auxiliary power source to an auxiliary power source during stopping in a reverse direction. CONSTITUTION:When a DC power of an auxiliary power source circuit 1041 is interrupted, a voltage detector 34 is operated to interrupt a gate signal applied to an inverter 14 and a thyristor 32. At this time, an AC power is continuously supplied from an auxiliary power source circuit 1042 under operation to an AC bus 20. On the other hand, power is supplied from the circuit 1042 to the circuit 1041 under stoppage, and a filter capacitor 12 in the circuit 1041 is charged. However, since it is interrupted by the thyristor 32 and a diode 31, it is not supplied to a DC load 22. Thus, the excess current is not flowed to the AC bus 20.

Filed: 1989-09-14
Abstract: PURPOSE:To prevent application of voltage, in charging direction, onto a primary battery by detecting the voltage to be applied, in the charging direction, onto the primary battery and stopping the operation of a power source equipment based on a detection signal of voltage application. CONSTITUTION:When a charge preventing diode is broken or erroneously fixed with reverse polarity, voltage detecting means 3, i.e., a thyristor 7, is turned ON while a transistor 23 constituting a stopping means 4 is turned OFF, whereby current is not fed to the primary coil 22 of a step-down transformer 21 and the voltage, in the charging direction, to a lithium battery 2 is turned OFF. Consequently, when a voltage is applied, in the charging direction, onto a primary battery, i.e., the lithium battery 2, the voltage detecting means 3 detects the voltage and operates the stopping means 4 for a power source equipment 1 to stop current supply, whereby fault such as leakage of liquid or rupture of battery due to application of charging voltage onto the primary battery can be prevented.
