Title: Electric circuit opening/closing system using optical reflecting plate
Inventor: MARUYAMA TAKUZO
IPC: G02B6/42
Filed: 1994-02-15
Abstract: PURPOSE:To obtain an electric circuit opening/closing system using an optical reflecting plate without giving hazard such as electric shock, fire, explosion and occurrence of a noise to the user and the installation by utilizing an optical fiber and detecting a reflected wave of an optical signal passing through the optical fiber so as to open/ close an electric circuit. CONSTITUTION:A light emitting and light receiving circuit 9 (light emitting diode) generates light, the light passes through an optical fiber 12 via an optical demultiplexer and reaches an optical reflection switch 11 The light given to a light receiving circuit in the circuit a by bypass is less without turning on the switch 11, a photo transistor is not operated and no light receiving signal is extracted from the light receiving circuit. When the switch 11 is closed, an optical reflecting wave is generated, the light returns through the optical fiber 12 in a direction of the light emitting source (light emitting diode) and the wave is divided into two by the demultiplexer. However, a light quantity sufficient to activate the photo transistor is obtained and a light receiving signal is extracted. A power switch 8 is operated by the signal, an electric circuit is closed to supply power to an electric apparatus such as a lighting fixture, and when the switch 11 is open, the optical reflecting wave is lost and the power supply is stopped. Thus, a very safe local switch is obtained.

Abstract: PURPOSE:To maintain the electric conduction state between an inner pad part and a bonding wire(BW) for a long term by arranging an isolating member composed of a nitride film between the inner pad part bonded to the whole surface of the BW and an outer pad part surrounding the outer periphery of the inner pad. CONSTITUTION:An aluminum pad is composed of an inner aluminum pad 11 and an outer aluminum pad 12, and an isolating member 14 composed of a nitride film is arranged between both of them. When a gold wire 3 is bonded to the aluminum pad, the gold wire 3 is so positioned that the whole part of the upper surface of the inner pad 11 is covered with the circular plate part 3a of the gold wire 3. By bonding the gold wire to the aluminum pad, the upper surface of the pad 11 is joined to the gold wire 3, and the external periphery of the circular plate part 3a of the gold wire 3 is joined to the pad 12. Since the pad 11 is isolated from the pad 12 by the isolating member 14, the pad 11 is not corroded even if the pad 12 is corroded.

Thus the CPU 1 stores simultaneously the programs read out of the ROM 2 into the RAM 14 in various working tests. Then the CPU 1 reads out these program after the end of the working tests and compares successively the programs with each original one. Thus the normal working of each program is confirmed based on a fact whether the data are identical with each other or not in each address. In such a constitution, the program working state can be easily confirmed.

Filed: 1991-03-22
Abstract: PURPOSE:To shorten a defrosting time at the time of defrosting and to reduce power consumption by feeding refrigerant of high temperature and high pressure to a heat coil connected to a discharge port side of a compressor and radiating heat from the coil. CONSTITUTION:Refrigerant is fed to a heat coil 25 at the time of defrosting, and the heat coil 25 radiates heat removed at a cooler 9 together with a condenser and waste heat of a compressor through the refrigerant of high temperature and high pressure. The atmospheric air from an opening 23a is heated by the coil 25, fed through a chilled gas duct 23, discharged from a suction collecting port 21, sucked from a suction port 7b by a fan 10, and blown from a diffuser 7a to form a protective air curtain in an opening 1a. It is then sucked through a suction port 5b by a fan 8 to defrost the cooler 9. Since defrosting hot water heats the coil 25 by the hot atmospheric air, a defrosting time is largely shortened. Since a heat source of the defrosting hot air is the coil 25, power consumption can be remarkably reduced.
