Title: Constant voltage power supply circuit, semiconductor integrated circuit and ic card
Inventor: KADOKAWA SHIGERU
IPC: G05F1/613
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To obtain a stabilized output voltage from a voltage generated through a rectifier circuit by constituting an output circuit for feeding an output current corresponding to an input voltage formed through a voltage division circuit from the power supply voltage. SOLUTION: In a constant voltage power supply circuit 2, a reference voltage generated from a band gap reference voltage generation circuit 21 is subjected to level shifted through a level shift circuit and divided through a resistance voltage division circuit before being fed to an output circuit comprising an inverted Darlington circuit producing an output current. Current flowing through the output circuit increases as the input voltage increases and decreases as the input voltage decreases to absorb fluctuation of output voltage thus obtaining a stabilized power supply voltage. Furthermore, since the constant voltage power supply circuit includes no operational amplifier having a large gain in the feedback loop, oscillation due to fluctuation of output current is prevented even in case of low power supply filter capacity and a stabilized power supply voltage is obtained.

IPC: F15B11/04
Filed: 1992-01-20
Abstract: PURPOSE:To conform stoppage operation to lever operation sensation by supplying a flow control valve with reverse currents corresponding to the difference of the actual operation speed of a hydraulic actuator and control target speed set by a control lever in a short time when the control lever is changed over from the position of drive operation to the deceleration side. CONSTITUTION:The target-speed arithmetic means B of a controller 12 arithmetically operates the control target operation speed of a control lever 11 from the change of an output from a potentiometer PM for working a turning motor. An actual operation-speed arithmetic means C arithmetically operates the actual operation speed of the turning motor M from an output from a rotational- quantity detecting sensor S. When the output from the potentiometer PM exceeds a specified value and is conducted on the deceleration side and the difference of control target operation speed and actual operation speed reaches a fixed value or more, the operation of the lever 11 determines the magnitude of reverse currents and a time from the difference. A reverse-current supply means D supplies an electromagnetic type proportional flow control valve V with reverse currents only in a determined short time.
