Title: Stage controlling device
Inventor: TSUYUSAKI HARUO
IPC: H01L21/30
Filed: 1981-05-14
Abstract: PURPOSE:To improve shifting and positioning accuracy of a stage, by weighting digital data output of a comparator and controlling loop gain of a control corresponding to a difference between real and target shift distances. CONSTITUTION:A control computer 16 commands a stage 11 driven straightly by an oil pressure cylinder 13, by making target shift distance a digital signal. The target and real shift distances of stage 11 are compared and subtracted at a comparator 17. The comparator 17 output is weighted at a shift register 20 in correspondence with a command of the control computer. the digital output of shift register 20 is converted 21 into analog voltage. The digital voltage is converted 15 into analog current. The analog current from an amplifier 15 is converted into input fluid to the oil pressure cylinder 13 by an electric oil pressure servo valve.

Title: Current amplifying circuit
Inventor: OKASHIN YAMATO
IPC: H03F3/343
Filed: 1980-05-30
Abstract: PURPOSE:To suppress the dispersion of characteristics by obtaining a resistance value corresponding to a DC current amplification factor, by forming pinch resistors on the same semiconductor substrate as the 1st and 2nd transistor (TRs) and restricting the width of base diffusion region to the same as to individual ICs. CONSTITUTION:Pinch resistors 13, 14 are inserted respectively to the collector and the emitter of a TR12 forming a current Miller circuit MK, and an output current picked up from the collector of the 1st TR12 is taken as a driving current and fed to the base of the 2nd TR2, and all the circuit elements are formed on the same semiconductor substrate. Thus, even if the hFE of the TRs is varied, since the ratio of the resistance values of the pinch resistors 13, 14 is constant and the ratio of the pinch resistor 14 to a diffusion resistance 4 is changed, the variance of the collector current of the 2nd TR is not fluctuated. For example, when this circuit is applied to a tuning meter, the indication value of the tuning meter 17 can not be fluctuated.
