| PURPOSE:To hold a constant vibrating property of a piezoelectric pump, to keep a constant gas rate, and to enable to perform a reliable detection of an augular velocity, by controlling a drive voltage of a piezo-vibrating plate corresponding to a change in a dynamic impedance. CONSTITUTION:An output of an oscillator 17 is applied as a piezoelectric pump drive signal to a bridge circuit 30 for detecting a dynamic impedance via a dynamic impedance circuit 20 to drive a piezo-vibrating plate 12. If the dynamic impedance of the plate 12 changes, an unblanced voltage (e) between connecting contacts (c) and (d) of the circuit 20 is generated corresponding to the change. After the voltage (e) is converted 23 into a DC voltage ec, a difference in a voltage between the voltage ec and a reference voltage Ec is produced, and is applied as a control signal es to an electronic attenuator 21. This causes controlling of the drive signal of the plate 12 so that the signal es is brought to zero, allows the amplitude of the plate 12 to be kept in a constant manner, enables the amplitude of the piezoelectric pump to be held constant, and causes bringing of a gas current rate of gas, jetted from a gas chamber, into a constant manner. | ||||||

| PURPOSE:To generate a stable gas current and to enable reliable detecting of an angular velocity, by a method wherein a vibrating amplitude of a piezoelectric pump is detected, and the amplitude of the piezoelectric pump is controlled so that deviation between a detecting value and a reference amplitude value is brought to 0. CONSTITUTION:An AC output signal Vo of an oscillator 17 drives a vibrating plate 12 of a piezoelectric pump 11 through an amplitude control circuit 20. A frequency and a voltage, corresponding to the vibration of the plate 12, are applied to the control circuit 20 from the pump 11, and a control signal (e) corresponding to the amplitude of the plate 12 is generated. A damping ratio of an electronic attenuator 21 is controlled corresponding to the signal (e), and the output driving signal of the control circuit 20 is controlled so that the amplitude of the plate 12 goes to a reference amplitude. This causes the amplitude of the pump 11 also to be normally kept constant and allows a velocity of flow of gas exhausted from a gas current also to be held constant. | ||||||

| PURPOSE:To stabilize the output of a zero point, to enable to perform the operation of a sensor with a high performance, and to simplify a circuit constitution, by amplifying a difference in an output between a pair of temperature-sensitive elements through the working of a chopper amplifier. CONSTITUTION:If an angular velocity movement is applied from the outside and a gas current is deflected, temperature-sensitive elements 9a and 9b vary in a change in resistance with said deflection, and a signal Ve is outputted from a bridge circuit 20. The signal Ve is a DC signal which is sized corresponding to a magnitude of an angle speed applied to a gas rate sensor. After it is converted into an AC signal Vc of a given period by change-over switches 22a and 22b in a circuit 22, it is applied to an AC amplifying circuit 24. The circuit 24 applies the amplifying signal Vc to a modulating circuit 25 which converts an input AC signal into a DC signal corresponding to said AC signal to output it. | ||||||

| PURPOSE: To perform the best temperature correction of a sensor output by detecting respective resistance values of a couple of temperature sensing elements in a sensor main body. CONSTITUTION: A resistance detecting circuit 19 has a resistance circuit of the couple of heat wires 14a and 14b and resistances R a, R b, and R c whose values are already known and detects a voltage drop E 1 across the resistance R c for voltage detection when a constant voltage power source 21 is connected to the resistance circuit and applies a constant voltage E, and an arithmetic processing part 22 finds the resistance values R 1 and R 2 of the heat wires 14a and 14b according to the detected value E 1 and the sensor output X from the main body 18. Then when the resistance values R 1 and R 2 both increase or decrease, it is decided whether or not the current sensor output X is in an area set having a specific permissible range for an offset value; when it is decided that the sensor output X is in the area, the current sensor output X is set again as a corrected offset value and correction is performed so that the current sensor output X is zero.
