摘要： An angular velocity sensor includes first and second vibrators having a movable portion with driving and detecting purpose movable electrodes and a fixed portion with first and second side driving and detecting purpose fixed electrodes. The driving voltages applied to the first side driving purpose fixed electrode in the first vibrator is a first driving voltage including direct and alternating voltages. The driving voltage applied to the second side driving purpose fixed electrode in the first vibrator is a second driving voltage including direct and alternating voltages. At least one of the direct voltages, one of the alternating voltages, or one of duty ratios of the first and second driving voltages is controlled so that the first vibrator vibrates opposite to the second vibrator.

摘要： A semiconductor device includes gaps formed in a semiconductor substrate to provide an inner portion movable in x and y directions. Drive electrodes vibrate the inner portion in the x direction, and detection electrodes detect movement in the y direction generated when an angular velocity is applied thereto. Monitor electrodes generate monitor signals for monitoring movement of the inner portion in the x direction. Shield wires are provided between the drive and detection electrodes and the monitor electrodes to suppress capacitive coupling. Dummy electrodes adjacent to the output electrodes and capacitively coupled to the drive electrodes generate a dummy signal. Dummy signal wires are respectively connected to the dummy electrodes and to the circuit substrate. The dummy signal includes an induced component of a periodical signal and is supplied to the circuit substrate to cancel another induced component of the periodical signal in the drive and monitor signals.

摘要： To cancel in-phase components acting on vibrators of first and second sensor units in an angular velocity sensing direction Y, a differential amplification circuit obtains a differential waveform between a first angular velocity sensing waveform J1 and a second angular velocity waveform J2. Furthermore, to reduce a residual in-phase component of the obtained differential waveform, input gain adjusting circuits adjust an input gain of the first angular velocity sensing waveform J1 and an input gain of the second angular velocity sensing waveform J2 before these waveforms J1 and J2 are entered into the differential amplification circuit.

摘要： A semiconductor dynamic quantity sensor, for example, an acceleration sensor is formed on a SOI substrate having an activation layer and a supporting layer with an oxide film interposed therebetween. A structure for the sensor is formed in the activation layer. An opening is formed in the supporting layer and the oxide film to expose the structure. In this sensor, stress layer is formed in the activation layer at a side contacting the oxide film. The stress layer is removed at a region facing the opening to prevent the structure from cambering.

摘要： A semiconductor angular velocity sensor has a frame-shaped base portion, a detection oscillator connected to the base portion through a detection beam portion, and a drive oscillator connected to the detection oscillator through a drive beam portion. Each of the beam portions has a pair of beams each generally having a U shape and connected to each other through a bridge portion. Accordingly, the beam portions can have large rotational rigidity not to prevent oscillations of the oscillators.

摘要： An ultrasonic sensor device includes a substrate, a piezoelectric vibrator, and a Q-factor adjuster. The piezoelectric vibrator includes a pair of detection electrodes that face each other in a thickness direction of the substrate and a piezoelectric body interposed between the electrodes. The piezoelectric vibrator provides a membrane structure which is formed on a surface of the substrate and has rigidity lower than that of a remaining portion of the substrate. An ultrasonic wave is transmitted by the piezoelectric vibrator, and its reflected wave is received by the same piezoelectric vibrator. The Q-factor adjuster adjusts a Q-factor of the piezoelectric vibrator so that the Q-factor can be larger during a transmission period where the piezoelectric vibrator transmits the ultrasonic wave than during a reception period where the piezoelectric vibrator receives the ultrasonic wave.

摘要： A physical quantity sensor has a weight mass movable in a detection direction. Auxiliary capacitors are formed at both side ends of the weight mass in a non-detection direction by auxiliary movable electrodes and auxiliary fixed electrodes, respectively. When capacitances of the auxiliary capacitors change due to movement of the weight mass in the non-detection direction, a limiter circuit feedback-controls voltages applied to the auxiliary fixed electrodes to maintain the position of the weight mass unchanged. Thus, the weight mass is limited from moving in the non-detection direction thereby to improve accuracy in detection of the movement in the detection direction.
