Title: Offset compensating method for detecting circuit
Inventor: ISHIHARA TSUTOMU
IPC: G01B7/00
Filed: 1986-03-04
Abstract: PURPOSE:To perform the offset compensation of a detecting circuit suitable to an integrated detector by finding such a compensating resistance value that offset voltages at temperatures at two high and low points of the output of an amplifier and their temperature dependency are both minimum. CONSTITUTION:Offset voltages at an amplifier output terminal 21 are measured at a low temperature TL and a high temperature TH and divided by the gain of the amplifier 20. Consequently, offset values VL and VH converted into values at the input of the amplifier are found. Further, mans resistance values RL and RH of piezoresistance elements 1-4 are found. Then, when a voltage supplied from a bridge circuit 10 to an excitation terminal 7 is denoted as VE and the resistance of the element 1 is denoted as R1, compensating resistance values gammaS and gammaP of compensating resistances 5 and 6 for eliminating variations in the voltages VL and VH with temperature are calculated from said numerals. Here, when gammaS and gammaP are larger then zero (or when gammaS and gammaP are less than zero), the resistances 5 and 6 (or 5' and 6') are connected to the element 1 (or 2). Consequently, the output offset voltage of the amplifier 20 is adjusted and temperature-compensated so that it is minimum between the temperatures TL and TH.

Abstract: PURPOSE:To smoothly carry out speed change and facilitate the start on a slope by constituting the titled device from a main transmission and a load sensing machine for controlling the transmission. CONSTITUTION:The main transmission consists of an input side cylinder group which converts the revolution supplied from a pedal to an oil flow and an output side cylinder group which converts the oil flow to the revolution of wheels.

On the both input and output sides, fine speed change is permitted by setting a plurality of cylinders. When the pedal stepping force increases on an ascent, a hydraulic cylinder installed with the pedal sends oil into a valve opening/closing cylinder, and a valve is opened, and when the pedal stepping force decreases, the cylinder is returned to close the valve. Therefore, on the ascent, shift-down is carried out, and on a descent, shift-up is performed.
