    摘要: Embodiments of the present disclosure may include a piezoelectric pump having: a piezoelectric vibrator whose periphery may be fluid-tightly sealed; and a pump chamber and an air chamber that may be formed on front and rear sides of the piezoelectric vibrator. The piezoelectric vibrator may include: a main shim that may be formed of a conductive thin metal plate; a plurality of piezoelectric element layers that may be formed on the main shim; and an intermediate shim that may be formed between the plurality of piezoelectric element layers and may be made of an elastic metal material having mechanical recovery. The piezoelectric vibrator may be vibrated to perform a pumping operation.

    摘要: A vibratory gyroscope including an elongated vibrator having a central (neutral) axis (Y-axis), a drive unit for deforming the first direction such that the vibrator vibrates in a first (X) direction, an added mass attached to the vibrator at a position offset from the central axis in a second (Z) direction, and a detector formed on the vibrator. Rotation of the vibratory gyroscope about the second (Z) direction during vibration in the second direction causes Coriolis force to acting on the added mass in a direction parallel to the central axis. Because the added mass is offset from the central axis, a resulting vibration in the second (Z) direction is produced, which is detected by the detector. With this arrangement, the central axis of the vibrator is placed in parallel with the surface of rotation of the rotating system. Thus, rotations about two or three axes in each direction can be detected in such a manner that noise generation is prevented.

    摘要: A switch device is provided in which the coupling members are flexible in a plane perpendicular to the reciprocating direction of the driving bar. This allows significantly decreasing the length of the coupling members in the reciprocating direction so that a thinner switch device can be provided.
