Title: Pulsively operated amplifying circuit
Inventor: TANAKA AKIO
IPC: H03F1/02
Filed: 1981-10-27
Abstract: PURPOSE:To reduce power consumption of an FET amplifier through the pulsive operation. CONSTITUTION:A CW signal from a signal source 14 is modulated pulse amplitude by a pulse modulator 15 and a moldulating source 16, and amplified by a class A operation FET power amplifier 7. A terminal 3 is normally biased to a cut-off voltage and the amplifier is brought to a cut-off state. In inputting a driving pulse to an input terminal of a circuit 8, a gate voltage from a power supply input terminal 5 is set to a normal operating bias and the amplifier 7 is normally operated. This driving pulse is synchronized with an input signal of the amplifier 7, and when an input signal pulse is completed for amplification, the driving pulse is lost, the gate is again biased to the cut-off voltage and the amplifier 7 is inoperative. Thus, in using this system for a radar transmitter/receiver, the power consumption can be reduced, and the deterioration in the S/N of the receiver due to the leaked noise from the transmitter at no operation can be prevented.

IPC: E21B21/06
Filed: 1994-07-25
Abstract: PURPOSE:To eliminate the need for exchanging a sealing member as the need for the sealing member required for preventing back flow of mud water to a supply port is eliminated. CONSTITUTION:This separator has a conical cylindrical cover 82 formed to a trumpet shape in such a manner that its outer periphery flares gradually from one end toward the other end. This conical cylindrical cover 82 is so fixed to a right side wall 72 that its one end covers the supply port. Then, the conical cylindrical cover 82 is formed to the circular conical shape so as to converge gradually toward a right side part 72 and, therefore, guides the mud water falling onto the outer periphery of the conical cylindrical cover 82 toward the right part side 72. As a result, the mud water does not flow to the large-diameter aperture side of the conical cylindrical cover 82 any more and, therefore, the back flow of the mud water to the supply port 12B through the large-diameter aperture of the conical cylindrical cover 82 is prevented.
