Title: Controller for pwm control converter
Inventor: OKUYAMA TOSHIAKI
IPC: H01L21/027
Filed: 1981-11-11
Abstract: PURPOSE:To allow an ordinary cable and photocoupler to be used even when a switching frequency is high by applying a pulse signal for controlling the conduction of a transisitor through a resistor. CONSTITUTION:A current command signal (a) which is fed from a control circuit passes through a wiring cable and photocoupler 13 to a comparator 8. The comparator 8 inputs the signal and the output of a current transformer 7, outputs a valtage of +DC when the signal is larger than the output signal of a converter, while outputs a voltage of -DC in case opposite to the above. Since the comparator 8 and the resistor 14 for handling the high frequency pulse signal are disposed at the high voltage side near transistors 1, 2, it does not need a signal insulating photocoupler therein. Further, since signal transmission delay and th noise problem do not exist, ordinary wiring cable and photocoupler can be used.

Title: Heating/dehumidifying device
Inventor: WATANABE TAKEJI
IPC: F25B29/00
Filed: 1989-07-12
Abstract: PURPOSE:To enable optimization of a discharge temperature and execution of comfortable dehumidification by a method wherein a refrigerant heater having a compressor, a four-way valve, a first heat exchanger, a check valve, a pressure reducing device, a second heat exchanger, a blower, and a burner is formed with a closed circuit. CONSTITUTION:A high temperature and high pressure gas refrigerant compressed with the aid of a compressor 1 flows to a refrigerant heater 9 after the passage of it through a four- way valve 2 and flows to a second heat exchanger 6. The gas refrigerant emits heats for condensation and liquefaction, and is reduced in a pressure by a pressure reducing device 5 and flows in a first heat exchanger 3, where it absorbs heat from indoor air for vaporization and gasification and is returned to the compressor 1 through the four-way valve 2. Thus, indoor air is cooled and dehumidified by the first heat exchanger 3, and then heated by a second heat exchanger 6 without changing absolute humidity and discharged in a room. When a discharge temperature is reduced to a value lower than a room temperature, condensing capacity by the refrigerant heater 9 can be increased and condensing capacity by the second heat exchanger 6 can be reduced in a way that a blower 7 is turned ON and forced radiation is effected by the refrigerant heater 9. This constitution keeps a discharge temperature at a comfortable value even during a rainy season and a winter season and enables execution of comfortable dehumidifying operation.
