    摘要: Provided is an angular velocity sensor including a first vibration element, a second vibration element, and a support substrate. The first vibration element detects a first angular velocity about an axis parallel to a first direction. The second vibration element detects a second angular velocity about an axis parallel to a second direction obliquely intersecting with the first direction, and generates an output signal corresponding to a third angular velocity about an axis parallel to a third direction orthogonal to the first direction. The support substrate supports the first vibration element and the second vibration element.

    摘要: There is a need for a piezoelectric element capable of improving a productivity and a yield without impairing the piezoelectric characteristic and a method for manufacturing the same. A piezoelectric element is provided with a substrate, a first electrode film disposed on the substrate, a piezoelectric film disposed on the first electrode film, and a second electrode film disposed on the piezoelectric film. The piezoelectric film has a laminated structure composed of a plurality of crystallized piezoelectric thin films. The piezoelectric film having a predetermined thickness is formed by repeated cycles of a film formation step of forming a piezoelectric thin film and a crystallization heat treatment step of heat-treating the piezoelectric thin film to effect crystallization. In this manner, a piezoelectric film exhibiting uniform crystallinity in the film thickness direction may be produced.

    摘要: A vibrating gyrosensor includes a support substrate on which a wiring pattern having lands is formed. A vibrating element is mounted on a surface of the support substrate. The vibrating element includes a base part having a mounting surface on which a number of terminals connectable to the lands is formed. A vibrator part integrally projects from a side of the base part and has a substrate-facing surface coplanar with the mounting surface of the base part. The vibrator part has a first electrode layer, a piezoelectric layer, and a second electrode layer which are laminated on the substrate-facing surface. The vibrator part vibrates when an AC signal is applied between the first and second electrode layers. The central electric field strength of the AC signal is set at a position shifting to the positive direction from the center of a hysteresis loop of the piezoelectric layer.
