Crystal resonator plate and crystal resonator device

An at-cut crystal resonator plate (2) includes a first main surface (2a) on which a first excitation electrode (211) is formed and a second main surface (2b) on which a second excitation electrode (212) is formed. The at-cut crystal resonator plate (2) further includes: a substantially rectangular-shaped vibrating part (21) that is piezoelectrically vibrated when a voltage is applied to the first excitation electrode (211) and the second excitation electrode (212); a holding part (22) protruding from a corner part (21a) of the vibrating part (21) in a z′ axis direction of the at-cut crystal; and an external frame part (23) configured to surround an external circumference of the vibrating part (21) and to hold the holding part (22).. ... Daishinku Corporation

Optical low-pass filter and imaging device provided with optical low-pass filter

An optical low-pass filter (30) includes a vertically splitting birefringent plate (31), a 45° splitting birefringent plate (32), and a 135° splitting birefringent plate (33). The 45° splitting birefringent plate (32) and the 135° splitting birefringent plate (33) are adjacent to each other. ... Daishinku Corporation

Electronic component-use package and piezoelectric device

An electronic component-use package includes a base that holds an electronic component element, and terminal electrodes formed on a bottom surface of the base. The terminal electrodes have chamfered parts facing corner parts of the base bottom surface and having angles of chamfer ranging in ±10 degrees to a reference line. ... Daishinku Corporation

Piezoelectric device

A piezoelectric device has an insulated container including a frame portion. Four external connection terminals to be solder-bonded to an external substrate each have a shape with a bent portion in plan view in which the external connection terminal is extending from one of the four corners on a bottom surface of the frame portion in a long-side direction and a short-side direction of an outer peripheral edge of the frame portion. ...
