摘要： The present invention is related to an angular velocity sensor, and intends to improve the detection characteristic through a precise measuring of an angular velocity signal. For this objective, the invented angular velocity sensor comprises U-shape first and second piezoelectric elements(4),(5) bonded together sandwiching a detection electrode(6), wherein in at least one of the tuning fork arms(4a),(5a) the first and second piezoelectric elements(4),(5) are polarized in a direction of thickness along which the piezoelectric elements are bonded together. Driving electrodes(7),(12) and (8),(11) provided in diagonal arrangement on the tuning fork arm are supplied with driving signals inverse-phased to each other. In such a structure, the driving signals cancel to each other at the vicinity of detection electrode; as a result, the driving signals never mix with a detection signal to be detected by the detection electrode(6). Thus, the capability of detecting an angular velocity signal is improved.

摘要： An angular rate sensor detects an angular rate which is produced when a mobile body such as a motor vehicle moves. The angular rate detecting device comprises at least two angular rate sensors housed in a case perpendicularly to each other. The angular rate sensor comprising a pair of vibratory units which are interconnected by a connector in a tuning-fork configuration. The vibratory units of the angular rate sensors are vibrated at different frequencies. The angular rate sensors may be accommodated in a damper block, which may be housed in the case. Since the angular rate sensors are housed in the single case, the angular rate detecting device is compact in structure and small in size. With the angular rate sensors accommodated in the damper block, they are protected from resonance, crosstalk interferences, and noise, and hence can produce reliable detected output signals.

摘要： An angular rate sensor detects an angular rate which is produced when a mobile body such as a motor vehicle moves. The angular rate detecting device comprises at least two angular rate sensors housed in a case perpendicularly to each other. Each angular rate sensor comprises a pair of vibratory units which are interconnected by a connector in a tuning-fork configuration. The vibratory units of different angular rate sensors are vibrated at different frequencies. The angular rate sensors may be accommodated in a damper block, which may be housed in the case. Since the angular rate sensors are housed in the single case, the angular rate detecting device is compact in structure and small in size.

摘要： An angular rate sensor has a tuning fork structure composed of vibratory components. The vibratory components include piezoelectric drive and detection elements which are joined together into a tuning fork configuration, the drive and detection elements lying in respective orthogonal planes. Leads are electrically connected to the drive and detection elements, and lead terminals are electrically connected to the leads, respectively. The vibratory components are covered with a coating which is of a material having a lower elasticity than the elasticities of the vibratory components. The coating on the vibratory components effectively reduces the propagation of unwanted vibrations, thereby reducing output signal drifts.
