Title: Differential amplifier circuit
Inventor: UCHIYAMA SHINKICHI
IPC: H03F3/45
Filed: 1985-09-28
Abstract: PURPOSE:To expand a differential input voltage range and to improve the accuracy by adding a circuit using an operational amplifier so as to make the bias current constant. CONSTITUTION:A potential of a common connecting point of resistors R0, R1, R2 is compared with a reference potential decided by resistors R20, R21 at an operational amplifier OP5 and the potential difference is impressed to a common connecting point of the resistors R6, R7 as a voltage V3. When the potential of the common connecting point of the resistors R0, R1, R2 rises, the voltage V3 rises, and when the potential is decreased, the voltage V3 is decreased. Thus, a current (i) flowing to the resistor R0 is made constant to cancel the change in the current (i) due to an in-phase voltage fluctuation of each base of transistors Q1, Q2 and an output voltage fluctuation of an operational amplifier OP1.

IPC: G06F15/78
Filed: 1987-08-28
Abstract: PURPOSE:To increase the processing speed of a microcomputer, by using three system clock signals of different phases. CONSTITUTION:The addresses which are previously outputted to an internal address bus 11 in the timings of timing signals 21 and 22 are outputted to an external address bus 13 at the trailing edge of a timing signal 23. An address output circuit 12 consists of a flip-flop circuit and the delay time 1 of an address set to the trailing edge of the signal 23 is limited only to the delay time of a path reaching an output driver from a flip-flop. For input of data, the data on an external data bus 5 is latched by a data input circuit 6 at the trailing edge of a timing signal 19. Then the latched data is transferred to an internal register 9 via a data bus 8 in the timing of a timing signal 20. Thus the data set-up time 2 set to the trailing edge of the signal 19 is limited only to the delay time produced between the bus 5 and the circuit 6.

Filed: 1990-08-16
Abstract: PURPOSE:To feed documents sheet one by one surely by the co-operation of a separation pad and a feed-in roller by converting the kinetic energy of a vigorously inserted document to the elastic energy to be absorbed. CONSTITUTION:When a vigorously inserted document P is brought into contact with a separation pad 71, the separation pad 71 is slid against the elastic urging force. Thus, the kinetic energy of the document P is elastically absorbed and the force is restrained while the document reaches a contacting surface between the separation pad 71 and the feed-in roller 1. Accordingly, a satisfactory separation function can be exhibited so as to increase a multi-feed preventing effect.

Abstract: PURPOSE:To minimize the disturbance to an electric power system by controlling the opening and closing speed of a main steam control valve lift with setting to the characteristics of the valve flow quantity so that the changing rate of a steam flow quantity can be made constant. CONSTITUTION:The opening of a main steam control valve is controlled by a main steam control valve opening command 11 during a normal operation. At the valve testing time the output of a total closing signal transmitter 14 is applied on a rate limitter 15 by a valve test total closing command 12 and a function generator 18 gives to the rate limitter 15 the signal 20 giving the valve closing speed by the signal 22 giving the valve opening. The rate limitter 15 transmits the signal 21 changing to -100% governors lift from the valve opening of the normal operation time at the changing speed given by the signal 20. The function generator 17 converts the sum of the output of the valve opening command 11 and signal 21 into the value lift according to the characteristics of the steam flow of the valve and becomes a valve opening setting signal. When the valve is closed and becomes total closing, the valve test total closing command is released and the signal of a zero output transmitter 13 is transmitted and the valve is controlled in its opening direction.

IPC: G11B15/29
Filed: 1989-08-21
Abstract: PURPOSE:To reduce loss torque received by the pressing force of a spring and to obtain a stable pressing load on the capstan shaft of a pinch roller by comprising a device so that no direct energizing force of the spring can be applied on a pin. CONSTITUTION:The device is formed in such a structure that the spring 9 allowing the pinch roller 4 to be adhered on a capstan with its energizing force is engaged with a cylindrical ring 11, and the pin 15 is inserted to the cylindrical ring 11, and the pin 15 can be prevented from being directly pressed on the elongated hole 13 of a lever 7 which supports the spring 9 with the pressing force of the spring 9. Therefore, since no pressing force of the spring 9 is received with the pin 15, the loss torque received by the pressing force of the spring 9 with the pin 15 while the pinch roller 4 is moved from a position separated from the capstan to the position adhered by pressing on the capstan can be reduced. In such a manner, the stable pressing load on the pinch roller can be obtained.
