Title: Source follower circuit
Inventor: TERADA TOSHIYUKI
IPC: H03K19/0952
Filed: 1993-12-24
Abstract: PURPOSE:To improve the frequency characteristic by providing a coupling capacitor respectively between a source of a source follower FET receiving a signal and a gate of a current source FET of a source follower stage processing a signal of an inverted phase. CONSTITUTION:When input signals IN1, IN2 in a source follower circuit in biphase operation changes from 'L' to 'H', a level of source terminals N1, N2 of source follower FETs QS1, QS2 changes from 'L' to 'H'. Since a current of current sources FETQC1, QC2 of a source follower stage processing signals of opposite phase is increased, a potential at an output terminal is discharged at a high speed and changes from 'H' to 'L'. Conversely when the signals N1, N2 change from 'H' to 'L', the output potential changes from 'L' to 'H'. Furthermore, the gate width of the FETQC1, QC2 is made narrower than the gate width of the FETs QS1, QS2 to increase the capacity of coupling capacitors C1, C2 relatively and the amplitude of the signal at a gate electrode is increased.

IPC: G21D3/08
Filed: 1988-12-26
Abstract: PURPOSE:To hold a nuclear reactor water level in a prescribed water level even if abnormality is generated in a main vapor flow rate sensor and a feed water flow rate sensor by bringing a water level signal of a nuclear reactor and a mismatching signal to feedback to an inlet side of a main water level controller and an outlet side, respectively. CONSTITUTION:To a main water level controller 1, only a deviation signal of a water level set value 3 and a nuclear reactor water level 4 is inputted. A three/single changeover switch 2 is connected to an outlet side of the controller 1, and a mismatching flow rate 6 being a deviation of a main vapor flow rate 9 and a feed water flow rate 10 is constituted so that it only passes through the switch 2, and thereafter, added to an output of the controller 1. That is, a signal obtained by adding the mismatching flow rate 6 to the output of the controller 1 is sent out as a feed water command to turbine driving feed water pumps TD1, TD2 and motor driving feed water pumps MD1, MD2. In such a way, even when a feedback signal of the feed water flow rate or the main vapor flow rate comes not to indicate a normal value due to a fault of a sensor, etc., although a fluctuation is given temporarily to the feed water flow rate and the nuclear reactor water level, the nuclear reactor water level is returned to an initial water level before abnormality of the feedback signal is generated, and maintained normally.
