摘要： A sensor includes detecting element (28) with an acceleration sensor, which is formed of weight (18) coupled to rigid section (14) via flexible section (16), substrate (10) confronting weight (18), and an electrode section including opposed electrodes (20, 22, 24, 26) placed on respective opposed faces of weight (18) and substrate (10).

摘要： A vibrator is received within a case and the case is contained in a containing portion. Further, the case is arranged to be supported by the surrounding terminals having first ends thereof embedded in the containing portion. By virtue of the described configuration, the vibrator is securely retained by the case even if strong vibrations are applied to the terminals. With this configuration, an angular velocity sensor ensuring the strength to retain the vibrator even if the vibrator is reduced in size and causing no degradation of the output characteristic even when subjected to strong vibrations can be provided.

摘要： An angular rate sensor is capable of restraining an output voltage of the sensor from being offset by suppressing a current flowing in and out of a common terminal so as to prevent it from flowing in and out of a side of a reference voltage generator. The angular rate sensor is provided with a buffer between a reference voltage generator and a support pin, which serves as a common terminal for a vibration exciter, a detector for detecting a level of vibrations, and a detector for detecting a Coriolis' force. A current flowing in and out of the support pin is prevented from flowing in and out of a side of the reference voltage generator.
