Abstract: An angular velocity sensor includes: a substrate; a drive beam supported via a support member with a fixing part; a drive weight supported with the drive beam; a detection weight supported via a beam part including a detection beam with the drive weight; and a detection part in the detection beam generating an electric output corresponding to a displacement of the detection beam when an angular velocity is applied. When the angular velocity is applied while the drive weight and the detection weight vibrate and are driven by the drive beam, the detection beam is displaced in a direction intersecting the vibration direction. The angular velocity is detected based on a change of an output voltage of a detection piezoelectric film in accordance with a displacement of the detection beam.

Abstract: When one direction of plane directions of a substrate is a first direction and a direction of the plane directions of the substrate perpendicular to the first direction is a second direction, a vibrating member is supported at an outer peripheral section via a plurality of beam sections having first beam-configuring members that can displace at least in the first direction and second beam-configuring members that are joined to the first beam-configuring members and that can displace at least in the second direction. In at least a subset of the plurality of beam sections, beam-configuring members on a side of the outer peripheral section among the first beam-configuring members and the second beam-configuring members are integrated with each other.

Abstract: A vibration angular velocity sensor includes a fixed portion, a movable portion, a beam portion, and an anti-vibration spring structure. The movable portion has driving-detection weights. The beam portion has detection beams, support members, and driving beams, and has a frame structure formed of the driving beams, the support members, and the driving-detection weights. The anti-vibration spring structure is disposed between the detection beams and the fixed portion and is deformable along a first axis and a second axis. The vibration angular velocity sensor causes the driving-detection weights disposed on both sides of the fixed portion to undergo driving vibrations in directions opposite to each other along the first axis about the fixed portion and detects an angular velocity based on a fact that the driving-detection weights vibrate also along the second axis upon application of the angular velocity.

Abstract: A vibration type angular velocity sensor includes a substrate having a surface; a plurality of fixation parts, a plurality of weights, two linear drive beams, a plurality of supporting members, a drive part and a detection part. The two linear drive beams are disposed on opposite sides of the weights in one direction so as to be connected to each other through the weights. The supporting members join the fixation parts to the drive beams. The drive part drives the drive beams to vibrate. The detection part generates an electric output according to displacement of the weights caused by an angular velocity applied thereto while the drive beams are being driven to vibrate. The fixation parts are disposed between the two linear drive beams.

Abstract: In a gyro sensor, two detection weights are placed in an outer drive weight to be arranged in an x-axis direction and coupled to each other via a coupling spring. By thus coupling the two detection weights via the coupling spring, it is possible to separate an in-phase-mode resonant frequency fin and an anti-phase-mode resonant frequency fanti from each other. As a result, it is possible to provide the gyro sensor which can suppress an output error on receiving an impact and perform more precise angular velocity detection.

Abstract: An electrostatic actuator includes a fixed electrode and a movable electrode arranged to face the fixed electrode. The movable electrode is configured to be displaceable with respect to the fixed electrode and a fixed portion. An attractive force acts between the movable electrode and the fixed portion. In the electrostatic actuator, a non-linear vibration of the movable electrode when a voltage is applied to the fixed electrode and the movable electrode is reduced by the attractive force acting between the movable electrode and the fixed portion.
