On side faces of the vibration member 14, piezoelectric elements 16a, 16b and 16c are formed. Two of the piezoelectric elements 16a and 16b are connected to resistors 26 and 28, respectively. Between the other feedback piezoelectric element 16c and these resistors, an oscillation circuit 30 is connected. A signal having a phase opposite to that of the signal output from the feedback piezoelectric element 16c is input to the vibration member 14 serving as a grounding terminal by a phase inverter 34. The signals output from the two piezoelectric elements 16a and 16b are input to a differential circuit 36. The differential circuit 36 is connected to a synchronous detection circuit 38 and connected to a smoothing circuit 40 and a DC amplifier 42 in series.

摘要： The vibrator includes a columnar vibrating body consisting of a piezoelectric material. The vibrating body is formed into a polygonal or cylindrical column and, when necessary, a through hole is formed axially thereof. Furthermore, the vibrating body is polarized. On side faces of the vibrating body, at least three external electrodes are formed. Also, when the through hole is to be formed, an internal electrode is formed on its inner circumferential surface. By applying the driving signal to these electrodes, the vibrating body bends and vibrates. And, when the rotational angular velocity is applied to the vibrating body about its axis, a coriolis force is produced responsive thereto. By this coriolis force, the vibrating direction of the vibrating body changes, and a voltage is produced between the two external electrodes. By measuring the voltage, the rotational angular velocity applied to the vibrator can be measured.

摘要： A piezoelectric vibrating device comprises a vibrating element supported by a support frame through at least two arms with the support frame surrounding the vibrating element. The vibrating element, the support frame and the support arms are of one-piece construction fabricated from a sheet of temperature-stable metal of constant elasticity. A ZnO layer is formed so as to overlay the vibrating element and also a portion of the support frame, and electrodes are formed so as to overlay a part of the ZnO layer on the vibrating element and another part of the ZnO layer on the support frame, respectively. One of the electrodes on the other part of the ZnO layer cooperates with the metal of constant elasticity to define a static capacitance with the ZnO layer serving as a dielectric body. An aluminum layer is interposed between the ZnO layer and the vibrating element.
