    摘要: An angular velocity sensor is provided that includes a frame, an oscillator and torsion bars that connect the oscillator to the frame. The frame, the oscillator and the torsion bar are formed integral with each other by etching a material substrate in the thickness direction of the substrate. The oscillator, configured in the form of an H, includes a support, two first arms and two second arms. These arms extend from the support in an arm-extending direction perpendicular to the thickness direction of the substrate. The oscillator includes a mounting surface that is provided with a piezoelectric driver for generating in-plane oscillation of the oscillator, and with a piezoelectric detector for detecting out-of-plane oscillation of the oscillator.

    摘要: A structure with superior shock resistance is proposed for a parasol-type acceleration sensor. The acceleration sensor comprises a support portion the lower end of which is fixed to a substrate; a beam portion on which a detection element for applying changes to an output signal in correspondence with strain caused by acceleration acting on the detection element is formed, one end of the beam portion being connected to the top part of the support portion; a suspended weight connected to the other end of the beam portion; and a stopper substrate with a window portion through which, in order to guide an output signal of the detection element via a pad that is formed on the upper end face of the support portion, a conductor lead that is connected to the pad passes. Overswing of the weight is limited by means of the stopper substrate.
