Title: Variable gain differential amplifier circuit
Inventor: IHARA HIROSHI
IPC: H03G1/00
Filed: 1983-04-01
Abstract: PURPOSE:To attain stable AGC feedback by applying a fixed component and a variable component of a gain control current from separate current sources to eliminate the need for limitation to the variable range of a gain control voltage. CONSTITUTION:The current given to the 1st differential pair (transistors TRs 101, 102) and the 2nd differential pair (TRs 103, 104) is divided into the fixed component (1-alpha)I0 and the variable component alphaI0 required for the variable gain and the components are applied from separate current sources 401 and 112. That is, the maximum value of the variable component of an emitter current I1 is alphaI0 and the remaining (1-alpha)I0 is the minimum value of the fixed component. Then, the fixed component (1-alpha)I0 of the emitter current is supplied from the current source 401 and the variable component alphaI0 is supplied from the current source 112. The emitter current I1 given to the 1st differential pair (TRs 101, 102 and resistors 113, 114) is limited so as not to exceed alphaI0 (alpha=RE2/RE1+RE2).

Title: Dual-system type hydraulic brake pressure control valve unit for vehicle
Inventor: NAGASHIMA TAKU
IPC: B60T17/18
Filed: 1981-04-16
Abstract: PURPOSE:To ensure hydraulic pressure control upon one system failure, by supporting, with three pins, a lever which transmits the force of a spring to two pistons, so that the lever is surely stuck in case of one system failure. CONSTITUTION:Two pistons 5 are disposed in a body 1, and are subjected to the force of a one spring 19 through a lever 12. The lever 12 is supported by a pin 10 and as well pins 9 with clearances 16, 14 therebetween, respectively, and normally balances the spring force to the two pistons. Upon one system failure the lever 12 is limited to its tilt motion due to the provision of the clearances 14, 16 so that the lever 12 surely transmits the whole spring force to the piston in the other system. The tilt motion of the lever 12 is not so great due to the provision of three pins, thereby the operation of the control valve device is assured upon one system failure.
