Patent JP-H04257126-A (JP)
Title: Transmission/reception equipment
Inventor: FUKUDA KUNIO
IPC: H04B1/56
Filed: 1991-02-08
Abstract: PURPOSE:To prevent the interference and the degradation in reception sensitivity by providing a signal line through which a carrier signal is supplied to the modulating circuit of a transmission circuit, a frequency dividing circuit, and a circuit which inhibits supply of the carrier signal in the reception slot period. CONSTITUTION:In the transmission slot period, a switch circuit 55 is turned on by a control signal Sw, and a voltage Vcc of a terminal 54 is supplied to a frequency dividing circuit 52, and a carrier signal Sc is taken out from the circuit 52. In the reception slot period, the circuit 55 is turned off by the control signal Sw, and the circuit 52 itself is not operated because the operating voltage Vcc is not supplied to the circuit 54. Since the carrier signal Sc is not outputted from the circuit 52 though an oscillation signal Sn from an oscillating circuit 51 is supplied to the circuit 52, the carrier signal Sc or a transmission signal St is not leaked to a reception circuit 20, and the interference and the degradation in reception sensitivity are prevented.

Title: Leak detecting method and device for sealed gas and the like
Inventor: YABE SHOZO
IPC: G01M3/22
Filed: 1991-02-08
Abstract: PURPOSE:To easily find pinholes and the like by sealing helium or its mixed gas into the seal section of a communication cable and the like, and introducing the atmospheric air outside the range of a measured object to a detector as the reference gas to detect the measured gas. CONSTITUTION:Helium or its mixed gas is fed into a cable 5 buried under the ground 6 with the preset pressure. If an injury such as a pinhole exists on the cable 5 or a connection section 51, helium gas leaks from there. A suction pump 8 is operated, the atmospheric air is sucked through a suction pipe 2, and a suction pipe 3 is inserted into a manhole 7 to suck the measured gas. The gas passes through an ion exchange film tube 4 before reaching a detector 1, it is removed with steam to have nearly the same humidity as that of the atmospheric air, and it enters a sample side of the detector 1. The difference from the atmospheric air fed to the reference side, i.e., the existence of helium, is detected by a bridge circuit and displayed on a meter.

Title: Refrigerating air conditioner
Inventor: SASAKURA MASAHIKO
IPC: F24F1/00
Filed: 1994-03-10
Abstract: PURPOSE:To prevent the oil-containing refrigerant from entering a compressor when one compressor is stopped by connecting a plurality of enclosed type compressors in parallel in one refrigerant system, and connecting the liquid return pipe from an accumulator to a connecting pipe to connect a closed container of each compressor to each other. CONSTITUTION:A plurality of, e.g. two sets of compressors 3, 4 are connected to one refrigerant system in parallel, the respective closed containers are connected to each other through an equalizing oil pipe 14, and a liquid return pipe 18 from the bottom of an accumulator 9 is connected to the equalizing oil pipe 14. When both compressors 3, 4 are operated, the mixture of the refrigerant and oil stored on the bottom part of the accumulator 9 is allowed to enter the respective compressors 3, 4 through the liquid return pipe 18 and the equalizing oil pipe 14. This constitution eliminates the suction force of the compressor 4 when one compressor 4 is stopped, allows the entered mixture to be fully sucked by the compressor 3 to avoid the in-flow into the compressor 4, and prevents the oil in the closed container of the compressor 4 from being diluted by the refrigerant.

Title: Scroll type compressor
Inventor: HASHIMOTO YUKIKAZU
IPC: F04C29/02
Filed: 1986-02-25
Abstract: PURPOSE:To feed a proper quantity of oil corresponding to the number of revolution onto a slidable movable part by installing a plurality of plates supported by a plurality of springs into the differential pressure oil feeding hole of a shaft and shifting said plates in the radial direction by the centrifugal force. CONSTITUTION:Two semicircular shaped plates 19 are installed into the upper part of the differential pressure oil feeding hole 16 of a shaft 11 so as to be attached each other by a spring 20. Since the both plates 19 are supported so as to move only in the radial direction, the centrifugal force acting onto the both plates varies when the number of revolution of the shaft 11 varies, and the gap between the both plates 19 varies. Therefore, the sectional area of the differential pressure oil feeding hole 16 varies, and a proper quantity of oil corresponding to the number of revolution of the shaft 11 can be supplied onto a slidable movable part.

Title: Discharge lamp lighting device
Inventor: SUIDOU SHINICHI
IPC: H02M7/48
Filed: 1994-03-11
Abstract: PURPOSE:To prevent streaks on a discharge lamp and eliminate need of a streak erasing circuit by generating high frequency waves, whose frequency differs in the first half and second half of one period, on the primary side of a transformer. CONSTITUTION:When a DC power is supplied to a switching part 20 from a power supply part 10, a resonance current is generated in a resonator circuit composed of a capacitor 25 and the primary winding 29A of a transformer 29. The resonance frequency at this time is determined by the capacitance of the capacitor 25 and the inductance of the winding 29A. When resonance is generated and a high frequency AC voltage generated in the secondary winding 29B exceeds half a period, a capacitor 26 is connected with the above- mentioned capacitor 25, and the resonance frequency is determined by the composite capacitance of the two capacitors 25, 26 in parallel connection and the inductance of the winding 29A. Accordingly the resonance frequency differs in the first half and later half of one period, and generation of streaks can be prevented as high frequency power has different amplitude in the first half and second half of one period.
