An angular velocity detection element includes: a drive vibration arm configured to perform flexural vibration according to an applied drive signal; and a detection vibration arm configured to perform flexural vibration according to an applied angular velo...

An apparatus in one example comprises a vibrating beam, a first drive component, and a second drive component. The first drive component for a first time period oscillates the vibrating beam in a first direction to sense angular rate of the vibrating beam....

A dynamic-quantity sensor includes two piezoelectric vibrators which are arranged such that stresses generated by a dynamic quantity, such as acceleration, are applied in opposite phases to the piezoelectric vibrators. A current-voltage converting and sign...

The gyrometer has displacement engines (16, 17) exciting two orthogonal oscillation modes of a micro electro mechanical system (10) to cause alternately right or left circular movements of a suspended mass (11) of the system. A phase shift measuring circui...

A vibrator (4) has a pair of vibrating bodies (3) with both end portions fixed together by intermediate metal portions (2). Buckling vibration is applied to the vibrating bodies. Detection electrodes (9) output signals corresponding to the magnitude of the...
