Abstract: PURPOSE:To provide versatility for a circuit and to make it into an IC by providing an impedance matching circuit with the feedback impedance and input impedance of an operational amplifier as a switched capacitor filter circuit to accurately match the input impedances of variously constituted subscriber circuits while using the same circuit. CONSTITUTION:The impedance matching circuit of the subscriber circuit is composed of a high-precision fixed resistor R, operational amplifier OP 1, and switched capacitor filter circuit provided with an input impedance ZT and a feedback impedance ZX composed of a switched capacitor. Then, the operational amplifier OP 1 is an active filter equipped with the input impedance ZT and the feedback impedance ZX and this active filter is composed of the switched capacitor filter circuit. Thus, by combining the fixed resistor R and the switched capacitor filter, the input impedances of variously constituted subscriber circuits can be precisely matched with a desired complex impedance.

Title: Flow rate regulating valve with function of compensating pressure
Inventor: ARAKI RIYUUKICHI
IPC: F16K17/22
Filed: 1979-12-12
Abstract: PURPOSE: To control the flow rates of a normal flow and backward flow by making an orifice connection between two variable restrictors of area consisting of a spool returning to a prescribed position by a spring and valve housing and then by moving the spool according to a difference in pressure across the orifice.  
     CONSTITUTION: When a fluid enters from port 2 and exits from port 3, the fluid has a difference in pressure across orifice 13 and this operates upon both ends of spool 4 in pressure chambers 14 and 15. When this pressure difference is greater than the elastic force of spring 5, spool 4 is slid to left to increase the area of variable restrictor 8 while decreasing that of variable restrictor 9, preventing the fluid from flowing from hollow part 11 to port 3. When the pressure due to the pressure difference across orifice 13 gets balanced with the force of spring 5, spool 4 stops and a constant flow rate is obtained. When it enters from port 3 and exits from port 2, on the other hand, pressure at the side of hollow part 11 increases above that at hollow part 10 and this pressure difference exceeding the elastic force of spring 5 slides spool 4 to right until the pressure difference gets balanced with the force of the spring, so that a constant quantity of the fluid flow out of port 2.

Title: Image sensor device
Inventor: YAMAMOTO HIDENORI
IPC: H04N1/12
Filed: 1984-07-31
Abstract: PURPOSE:To obtain a nearly constant S/N ratio even in case of a variation in the conveyance speed of a document by varying the electric current value of a solid-state light emitting element according to the conveyance speed and also varying the scanning time of a photoelectric converting element. CONSTITUTION:A conveyance speed detecting circuit 3 outputs conveyance speed information of the document to a current control circuit 2, which then judges whether the conveyance speed is faster than a specific conveyance speed or not to increase the current to a light emitting diode array 1 when the input conveyance speed is faster than a specified speed or decrease the current when the speed is slower. A linear image sensor 4, on the other hand, outputs a photoelectric conversion signal corresponding to the brightness of the light emitting diode array 1, but scanning density is constant, so the scanning time is also varied according to the conveyance speed of the document 7. The scanning time is shortened when the conveyance speed is fast or extended when the speed is slower. Thus, a signal processing circuit 5 obtains speed information from the conveyance speed detecting circuit 3 to vary the scanning time of the linear image sensor 4 according to the conveyance speed.
