Patent number: 7587941Abstract: A vibration piezoelectric acceleration sensor including a pair of beam shaped members linearly and oppositely disposed on a frame, a support body supporting the beam shaped member, and a holding part holding the support body moveably in a linear direction, and another pair of beam shaped members disposed linearly and oppositely crossing the pair of beam shaped members detecting acceleration in two axes, i.e. X and Y directions. The beam shaped members are extended and retracted by the acceleration transmitted to the support body through the holding part, changing a natural oscillation frequency. Accordingly, a high change ratio of resonance frequency can be provided with the detection of the acceleration, and the acceleration in the direction of two axes can be detected without being affected by a change in temperature.Type: GrantFiled: February 14, 2005Date of Patent: September 15, 2009Assignee: Panasonic CorporationInventors: Jiro Terada, Masaya Nakatani, Takami Ishida

Patent number: 6598476Abstract: Here disclosed is an angular velocity sensor with much accuracy, not allowing other vibration components to mix into the Coriolis force component. The angular velocity sensor contains a first through a fifth beams: the first, the second, and the third beams have a length of substantially the same and disposed in a substantially parallel arrangement on a substantially the same plane—with the first beam placed between the second and the third; the fourth connects each one end of the first through the third, while the fifth connects each other end of them. The first beam is supportively fixed at its mid-portion. The first beam serves as a detector; the second serves as a driver; and the third serves as a monitor.Type: GrantFiled: March 19, 2002Date of Patent: July 29, 2003Assignee: Matsushita Electric Industrial Co. Ltd.Inventors: Jiro Terada, Katsunori Matsubara, Takeshi Yamamoto

Patent number: 6532817Abstract: An integral bimorph angular rate sensor is formed by directly bonding two tuning fork members in the thickness direction to enhance the detecting sensitivity of the angular velocity sensor. The individual tuning fork members are formed from a single crystalline piezoelectric material such as quartz and are bonded in the crystal axis direction as to establish a piezoelectric phenomenon wherein the piezoelectric materials of the bonded tuning fork members have inverse polarities in their width or thickness directions.Type: GrantFiled: April 27, 1999Date of Patent: March 18, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Junichi Yukawa, Jiro Terada, Kuniharu Nakamaru, Minoru Ishihara, Kozo Ono
