Title: Vibration detecting device
Inventor: IWATA TOSHIO
IPC: G01R31/08
Filed: 1982-03-08
Abstract: PURPOSE:To make it possible to perform automatic detection of the fault of wire  breakdown, by superimposing a DC signal on a detecting coil which outputs an AC signal corresponding to the vibration, and issuing a report and the like based on the  change in the DC signal. CONSTITUTION:The AC signal corresponding to the vibration is generated from the  detecting coil 11 of a vibration sensor 1, which is mounted on a body to be measured  and vibrated as a unitary body. The signal is applied to a signal processor 3 from one  terminal 13 of the coil 11 through a signal line 12. Meanwhile, the DC current flows  from a DC constant voltage power source 29 to a resistor 21, the coil 11, the other output terminal 14 of the coil 11, a resistor 22, and the like. Since the DC resistance of the coil 11 is small, the DC voltage, which is superimposed on the AC signal at the output terminal 14, becomes a constant value corresponding to a voltage dividing ratio of the  resistors 21 and 23. The AC signal is moved by an LPF formed by a capacitor 26 and  the resistor 23. The constant DC voltage is applied to a comparator 25 through a capacitor 24. When the signal line 12 or the coil 11 is broken by the vibration, the output of the comparator 25 is inverted. The reporting, controlling, and the like are performed  based on said output, and the fault of the wire breakdown can be automatically detected.

Abstract: PURPOSE:To attain the operation at several hundreds MHz or over by giving an input signal to a differential amplifier circuit, obtaining two outputs being noninverting and inverting outputs with a gain of 2:1, shifting the phase of one output, not shifting the phase of the other output, adding them to a next stage circuit, in which they are added in phase. CONSTITUTION:FETs Q1, Q2 form a differential amplifier circuit, and a signal S2 in phase to a signal S1 resulting from inverting the phase of an input signal SIN is obtained through its load resistor with a gain of 2:1. The signal S1 is phase-shifted at a turning angle in response to an angular frequency by a capacitor C1 and the signal S2 is given to each gate of FETs Q4, Q5 forming an in- phase adder circuit while the phase of the signal S2 is unchanged. The resistance of each resistor is selected as R1=R2=R9 and R6=R7 to make the characteristic of the FETs Q1, Q2 and the FETs Q3, Q4 equal to each other. Thus, the circuit is formed without use of a feedback circuit and the circuit is operated in an excellent way at a frequency of several hundreds of MHz or over.
