Abstract: PURPOSE:To prolong the service life of a battery to reduce troublesome replacing operations, and simplify the maintenance and management by incorporating an impeller rotating by the flow of fluid in a pipe-line in which an electromagnetic force-driven control valve is installed, and operating a generator by the impeller to supply current to a battery serving as a power source for operating the control valve. CONSTITUTION:When an impeller 21 is rotated, a drive shaft 35 and a permanent magnet 33 are rotated integrally with the impeller in oder to actuate a generator 31. The generated alternating current is rectified to direct current by a rectifier 41, and the direct current is supplied to a battery 42 to charge it. Further, the direct current flowing from the battery 42 is supplied through a controller 43 to a solenoid coil 12 to open a control valve 1. When the control valve 1 is closed, the impeller 21 is seated on a valve seat 47 by spring force of a shut-off spring 48, and when the control valve 1 is opened to allow a fluid to flow, the pressure at the portion between a valve-opening 5 and a check valve 45 is reduced to separate the impeller 21 from the valve seat 47. Thus, the fluid flows from an inlet 3 to an outlet 4, and the fluid passing through the check valve 45 collides with impeller blades 23 to rotate the impeller 21.

Abstract: PURPOSE:To calibrate a device by its internal oscillator without requiring any standard AC signal generator by finding the difference between the output signal of an amplification part and the output signal of the oscillator when the output signal of the oscillator is amplified. CONSTITUTION:When an AC voltage measurement range is calibrated, a switch SW1 is switched to the side of the oscillator OS. The oscillator OS outputs a sine wave S1 of frequency f2. The output S1 is amplified by the amplification part 10. A computing element U4 inputs the output S2 of the amplification part 10 through a resistance R11 and the output S1 of the oscillator OS through a resistance R9 and adds them together. The signals S1 and S2 are in opposite- polarity relation. Namely, the computing element U4 calculates S1+(-S2)=IS1+(- IS2) to obtain the difference between the signals S1 and S2. Then the resistance values of the resistances R9 and R11 are set previously so that IS1 = IS2 when the frequency characteristics of the amplification part 10 are properly corrected.
