Title: Pulse generating circuit
Inventor: KONDO CHIAKI
IPC: H03K5/00
Filed: 1986-03-03
Abstract: PURPOSE:To minimize number of components and to miniaturize the chip size by forming two rectangular wave signals having a width in response to an input signal and its inverted signal and generating a pulse signal synchronously with one leading and other trailing. CONSTITUTION:When an input signal I is inverted to '0' level and the inverted signal I' is inverted to '1' level, and an output of a NAND gate 41 goes to '1' level with a delay of a prescribed time. A transfer 52 is turned on at the same time and an output terminal O' goes to '1' level. Then the output of a NAND gate 42 (output at terminal Q) goes to '0' level with a delay of a prescribed time. Thus, a transfer gate 51 is turned off and the transfer gate 52 is turned on, then the output terminal 0' goes to '0' level. The process above is repeated when the level of the input signal I changes and the pulse signal is outputted at each occasion.

Abstract: PURPOSE: To prevent the thermal rising of discharged refrigerant gas without lowering the heating capacity for defrosting even under cold open air or other conditions by providing a refrigerant cycle, an intermediate circuit, a defrosting valve device, and the first and the second bypass circuit.  
     CONSTITUTION: When frosting is advanced in an evaporator 8, a three-way valve 13 is switched over by a defrosting signal to close a liquid line electromagnetic valve 5. Consequently, the discharged refrigerant gas from a high stage side compressor 2 is conducted to the evaporator 8 through the first bypass circuit 41 as a dotted line arrow shows. After defrosting the evaporator 8 by the compression heat, it is separated into gas and liquid and returned to a compressor 1. Meanwhile, the discharged refrigerant gas is partly introduced into a liquid-receiver 4 through the second bypass circuit 50, and forces out the refrigerant liquid in the liquid-receiver 4 for injecting into a suction pipe 26 in the high stage side compressor 2 through an intermediate circuit 30. This construction serves to maintain and stabilize the temperature of the discharged refrigerant gas in the high stage side compressor.
