摘要： A crystal resonator has a structure in which upper and lower substrates are stacked and integrally and airtightly bonded to the upper and lower surfaces of an intermediate crystal plate. The upper and lower substrates have a concavity on their surfaces facing the intermediate crystal plate to define a cavity in which the crystal resonator element is airtightly sealed in a cantilever manner. The upper and lower bonding surfaces of the intermediate crystal plate are mirror-polished and then provided with a conductive film. Each bonding surface of the upper and lower substrates is a mirror-polished crystal surface.

摘要： In order to provide a tuning fork type piezoelectric vibrator provided with vibrating arms which can improve shock resistance while suppressing a CI value to a small value, a first groove (base end side) and a second groove (tip side) extending along the longitudinal direction from the base end of the vibrating arm and divided into two in the longitudinal direction are formed on at least one of a front surface or a back surface of the vibrating arms. Then, a ratio L2/L1 which is the ratio of the length L2 of the first groove to the length L1 from the base end of the vibrating arm to the tip of the second groove, is set between 0.35 and 0.65, and a ratio d/L1 which is the ratio of a space d between the first groove and the second groove to the length L1 from the base end of the vibrating arm to the tip of the second groove, is set between 0.010 and 0.016.

摘要： Thermomètre à quartz délivrant un signal dont la fréquence est une fonction sensiblement linéaire de la température.
Le thermomètre comprend un diapason 2 muni d'électrodes 12 à 15 et 12' à 15' disposées respectivement sur les bords des faces supérieure et inférieure des branches 8 et 10 du diapason. Ces électrodes sont alimentées pour faire vibrer le diapason en torsion. Les branches 8 et 10 sont sensiblement parallèles à l'axe X du cristal de quartz. La direction perpendiculaire aux faces du diapason fait un angle 6 avec l'axe Z du cristal. L'angle 6 est compris entre -30° et +30°.-

摘要： A tuning fork type quartz crystal resonator may be used to generate higher harmonic oscillations at the base portion thereof by appropriate selection of the width (W) and thickness (t) of an arm portion of the resonator as well as the cut angle of the original crystal. This tuning fork type quartz crystal resonator generating higher harmonic oscillations shows stable characteristics against temperature changes.

摘要： A vibrator element (200) includes a base section (220), a pair of parallel vibrating arms (230, 240) projecting from the base section (220) in a +Y-axis direction, and arranged at a certain distance in a plan view as measured in an X-axis direction, perpendicularily intersecting with the Y-axis direction. The vibrator element (200) further includes a support arm (250) disposed between the pair of vibrating arms (230, 240) and projecting from the base section (220) in the same +Y-axis direction as the vibrating arms (23, 240). The base section (220) includes a first shrunk-width portion (222), disposed on the opposite side of the base section (220) with respect to the side on which the support arm (250) projects, and having a width in the direction opposite to the projection of the support arm (250) which gradually decreases with the distance from the base section (220).
