摘要： A thin film micromechanical resonator (resonator) having improved drive efficiency, a resonator gyro having improved sensitivity in detecting an angular velocity, and a navigation system and an automobile using the resonator gyro. The resonator includes a tuning fork structure made of a non-piezoelectric material, and a first electrode and a second electrode disposed respectively at the inner side and the outer side of the tuning fork arm. On the first and second electrodes, a first piezo film and a second piezo film are provided respectively, and a third electrode and a fourth are respectively provided electrode thereon. When an alternating voltage is applied to the third and fourth electrodes at the opposite phases each other, the tuning fork resonates in the direction perpendicular to the center line. The resonator gyro detects, at the sensing section which is formed of another electrodes and another piezo film, the Coriolis force generated in proportion to angular velocity given to the resonator.

摘要： An angular velocity sensor is provided, which is capable of accurate failure diagnosis on a detecting portion despite of its simple configuration and small size without providing additional means on an oscillator separately from the driving portion and a detecting portion. When a check signal for carrying out failure diagnosis is input to terminal (54) from outside, the degree of amplification at amplifier (45) is decreased, and the degree of amplification at amplifier (44) is simultaneously increased by an operation of AGC circuit (43). As a result, a driving signal having the decreased amplitude can be obtained at terminals (50) and (53), and a driving signal having the increased amplitude can be obtained at terminals (51) and (52). The driving signals are supplied to one driving electrode and another driving electrode, respectively, of a pair of driving electrodes spaced from each other across the center of the arm of a tuning fork type oscillator through terminals (50) to (53).
