Patent number: 8212458Abstract: A flexural-mode tuning-fork type quartz crystal resonator includes a proximal portion, a pair of vibrating arm portions, and a plurality of first concave portions. The vibrating arm portions project in a direction from the proximal portion. The first concave portions are formed into groove shapes in the upper and lower principal surfaces of the proximal portion, and extend in the widthwise direction perpendicular to the longitudinal direction of the pair of vibrating arm portions. The first concave portions formed in the upper principal surface of the proximal portion and those formed in the lower principal surface of the proximal portion are arranged at a predetermined interval not to face each other.Type: GrantFiled: June 28, 2010Date of Patent: July 3, 2012Assignee: Kyocera Kinseki CorporationInventors: Shigeru Kizaki, Ryota Kawai, Kazuyoshi Kawakita, Yoshiji Matsui, Shinichi Morishima

Patent number: 7851980Abstract: A tuning fork flexural crystal vibration device includes a base, two vibration arms, grooves, electrodes, and wirings. The base has a flat plate shape. The two vibration arms have flat panel shapes extending from a side surface of the base in the same direction. The grooves are provided for the two vibration arms so as to extend from base-side end portions of the vibration arms along the longitudinal direction of the vibration arms and are depressed in the thickness direction of the vibration arms. The grooves include front-side grooves which open in the front main surfaces of the vibration arms and are provided at least one by one for each vibration arm, and rear-side grooves which open in the rear main surfaces of the vibration arms and are provided at least one by one for each vibration arm. The bottom surface of the front-side groove does not face the bottom surface of the rear-side groove provided in the same vibration arm in which the front-side groove is provided.Type: GrantFiled: March 27, 2008Date of Patent: December 14, 2010Assignees: Kyocera Kinseki Corporation, Kyocera Kinseki Hertz CorporationInventor: Shigeru Kizaki
