    摘要： A physical quantity sensor 1 comprises a driving circuit 4 that drives a sensor element based on a reference signal; the sensor element 3 that is driven by the driving circuit 4 to convert an externally applied physical quantity to an electrical signal; and an amplifier circuit 5 that amplifies an output signal of the sensor element 3. The driving circuit 4 controls a driving signal, which drives the sensor element, based on the reference signal so that the driving signal is at a fixed level, and the amplifier circuit 5 has a gain characteristic that amplifies the output signal in a direction reverse to a direction in which the reference signal varies or the driving signal of the driving circuit varies. This configuration allows the physical quantity sensor to reduce output level variations in the sensor output against signal level variations in the reference signal and to make the sensitivity constant.

    摘要： A physical quantity sensor comprises a sensor circuit that converts an externally applied physical quantity to an electrical signal and outputs a detection signal; an adjustment circuit that adjusts the detection signal, which is received from the sensor circuit, to a predetermined signal; and an output circuit that forms an output signal from the signal of the adjustment circuit wherein the sensor circuit and the output circuit are driven by a common power supply voltage.

    摘要： A vibration body 1 includes a vibrator 2 having vibration pieces 7 and a supporting part 5, and a mounting substrate 11 for mounting the vibrator. The mounting substrate has a seat part 13 for supporting the supporting part, and a base part 12. The seat part 13 has a level difference above the base part, the level difference being at least equal to or higher than the oscillation width of the vibration pieces, and the seat part is also provided with an edge portion 14 having a curved line shape. A normal line direction at each position on the edge portion is the same as a reference direction determined for the mounting substrate, or has at least one different angle with respect to the reference direction. When the vibrator is mounted on the seat part 13, tangential directions at the end portion of the supporting part and the edge portion of the seat part coincide with each other at a mounting position selected from the edge portion having the curved line shape of the seat part. The angle for mounting the vibrator on the mounting substrate is determined by the normal direction at the edge portion of the seat part by the position adjustment between the end portion and the edge portion. In mounting the vibrator on the angular speed sensor, oscillation of the vibrator is not impeded, and a preferable fixing of the vibrator is achieved as well as being set at any angle within a predetermined angle range.

    摘要： Using an oscillating unit (601) that can start oscillation with a low voltage, an oscillation signal (S1) of the oscillating unit (601) is amplified via a waveform shaping unit (603), and is fed to a boosting control unit (105). A boosting unit (103) is caused to perform a boosting behavior by a boosting clock (Sa) with the same frequency as an oscillation frequency of the oscillation signal (S1) just after the oscillating unit (601) starts. Thereby, a whole electronic timepiece (100) can be self-actuated, even if a generation voltage is low. Further, the oscillating unit (601) is constituted such that a operating current always becomes constant. Thereby, the electronic timepiece can be provided with an electricity-generating unit (101) such as a solar cell with a one-stage constitution having a low open voltage.
