Title: Television receiving system
Inventor: TSUCHIDA SUSUMU
IPC: H04N5/44
Filed: 1992-10-30
Abstract: PURPOSE:To suppress an interference noise applied to an output screen by an induced current generated by magnetic flux leaked from a deflecting circuit or the like in a television receiver by removing the influence of the induced current in a TV receiving system for mixing broadcasting waves received by plural antennas having respective different receiving frequency bands by a mixer and supplying the mixed wave to the TV receiver through a coaxial cable. CONSTITUTION:When capacitors 2a, 2b are inserted into a signal system between the input terminal of a U/V tuner 3 and the ground of a BS tuner 6 in the TV receiver, a route into which an induced current is allowed to flow is opened to suppress an interference noise to be applied to the output screen by the induced current. When the output impedance Ro of plural cascade-connected signal processing blocks 31, 32 is reduced and the impedance Rs of a signal route between the blocks 31, 32 is made almost equal to the impedance Rg of an earth route, the interference noise applied to the output screen by the induced current can be suppressed.

Title: Freezer
Inventor: HIRAOKA SEIJI
IPC: F25B13/00
Filed: 1989-12-06
Abstract: PURPOSE:To prevent the reverse flow of a refrigerant irrespective of pressure conditions at the time of defrosting with hot gas and prevent the damage of a solenoid valve and the like, which may be caused by abnormal vibration, by providing a check valve in series with the solenoid valve on the way of a bypass pipe for controlling an outlet gas temperature. CONSTITUTION:A bypass circuit for controlling an outlet gas temperature is formed from a high-pressure liquid pipe connected to a liquid receiver 3 to a compressor 1 via a solenoid valve 11, a check valve 10a and a capillary tube 8, which are provided on the way of the compression course of the compressor 1. Further, a heat accumulating tank 6, a four-way valve 7, a volume regulating valve 9 and check valves 10b, 10c, 10d are incorporated in a cycle as the parts of a heat accumulation type hot gas defrosting system. In the case where defrosting is carried out in this freezer with which the hot gas defrosting system is associated, a refrigerant gas in the compression course tends to pass through the solenoid valve 11 and to flow reversely toward a liquid distributing pipe when pressure at the diverting part of the liquid distributing pipe, from which the outlet gas temperature controlling bypass pipe is branched, becomes lower than pressure at the bypass pipe mounting part of the compressor. However, the bypass pipe is closed by the check valve 10a to prevent the reverse flow of the refrigerant, whereby the abnormal noise and abnormal vibration of the solenoid valve 11, which may be caused by the reverse flow of the refrigerant, can also be prevented.
