Title: Control device of directional control valve in refrigerating cycle
Inventor: TAKAHASHI KIKUJI
IPC: F25B13/00
Filed: 1984-12-28
Abstract: PURPOSE:To simplify the structure of a four-way valve and consequently facilitate the control of the four-way valve by a structure wherein a signal generating circuit and an electric current control element are provided so as to change over the direction of current energizing the electromagnetic coil of the four-way valve and at the same time a permanent magnet to hold the four-way valve under working state within the four-way valve.

Patent JP-H03139925-A (JP)
Title: Center clipper circuit
Inventor: ITO HIDENORI
IPC: H04B3/23
Filed: 1989-10-25
Abstract: PURPOSE:To remove unnaturalness due to a center clipper and to suppress the deterioration of speech quality by setting up the I/O characteristics of a clipping circuit so that a signal of a prescribed level is outputted at the time of inputting a low level signal. CONSTITUTION:A level detector 93 measures an input signal level, and when the signal level is lower than a previously determined signal level TH, a selection circuit 95 selects the B side to output an attenuated signal from an attenuator 9 to an output terminal 92. When the input signal level is higher, the circuit 95 selects a signal inputted from an input terminal 91 and directly outputs the input signal to the clipping circuit. Since the attenuator 96 can attenuate the input signal to a low level such that its output signal can not be recognized as an echo, an input signal whose level is higher than the level TH determined by an absolute level is directly outputted and an output signal whose level is lower than the TH is attenuated and outputted as an attenuated signal. Thereby, the complete disappearance of signal does not occur in the clipping circuit and speech quality can be prevented from being deteriorated due to the ON/OFF of the center clipper circuit.
