摘要： An acceleration sensor is able to reduce the mount space thereof and to prevent detection precision from being lowered by yawing when external force is applied. The acceleration sensor reduces the mount space by attaching a circuit substrate so as to extend perpendicularly to a mounting substrate, and prevents detection precision from being lowered by yawing of the circuit substrate by setting the acceleration detecting direction of an acceleration detecting device mounted on the circuit substrate parallel to the main surfaces of both the mounting substrate and the circuit substrate.

摘要： An acceleration sensor includes a detection element having a plurality of piezoelectric ceramic layers laminated together and a pair of retaining members that retain an end portion of the detection element in a longitudinal direction thereof at two principal surfaces of the end portion. The detection element includes electrodes between the ceramic layers and on principal surfaces. The detection element obtains a voltage or a charge generated in the detection element in response to an application of acceleration from the principal-surface electrodes and the interlayer electrodes. The piezoelectric ceramic layers are not polarized in areas between the principal-surface electrodes and the interlayer electrodes within a retaining area in which the detection element is retained by the retaining members.

摘要： A compact, highly sensitive acceleration sensor that is not affected by factors other than acceleration, such as a change in temperature, includes a bimorph acceleration-sensor element including first and second resonators and attached to opposite sides of a base plate with respect to a direction in which acceleration is applied. One longitudinal end or both longitudinal ends of the acceleration-sensor element is/are fixed such that the resonators bend in the same direction in response to the acceleration. Changes in frequency or changes in impedance in the resonators caused by the bending of the acceleration-sensor element are differentially detected in order to detect the acceleration. The acceleration-sensor element is bendable about a central bending plane N1 in response to the acceleration, the central bending plane N1 being positioned at a central portion of the base plate with respect to the application direction of acceleration. Electrodes are disposed on main surfaces of the resonators, the main surfaces being substantially perpendicular to the application direction of acceleration. The height H1 of the resonators in a direction that is substantially perpendicular to the application direction of acceleration is smaller than the height H2 of the base plate in the direction that is substantially perpendicular to the application direction of acceleration.

摘要： An acceleration sensor includes a first resonator and a second resonator which resonate at independent frequencies and each of which includes a piezoelectric body and electrodes arranged on both main surfaces thereof, and a first base plate and a second base plate. A first unimorph type acceleration detection element includes the first resonator bonded to one surface of the first base plate, and a second unimorph type acceleration detection element includes the second resonator bonded to one surface of the second base plate. Each of the first and second unimorph type acceleration detection elements is fixed at one longitudinal end thereof or opposed longitudinal ends thereof such that the first resonator and the second resonator are diametrically opposed to each other or are arranged to face each other to allow the first resonator and the second resonator to independently deflect in response to the application of acceleration. When the two acceleration detection elements are independently deflected in response to the application of acceleration, acceleration is detected by detecting a difference between frequency changes of the first resonator and the second resonator or a difference between impedance changes of the first resonator and the second resonator.

摘要： A tuning fork-type vibrator includes a tuning fork-type vibrating body including a base and legs. The tuning fork-type vibrating body includes two piezoelectric substrates, an intermediate electrode, surface electrodes and an entire-surface electrode that are laminated together. The surface electrodes are separated by separating portions extending from the base to each of the legs. The widths of the separating portions at a point of connection to the circuit board are wider than those of the separating portions at other points. The separating portions are formed by dividing an electrode provided on the entire surface of a piezoelectric substrate in the vibrating body with a dicer or by laser radiation or etching.
