    摘要： A vector-signal processing circuit can be operated with low power consumption and can be configured so as to be cheap. Sensor signals in three-axial directions are individually rectified by full-wave-rectifier circuits individually formed by combining four diodes. Subsequently, the outputs of the above are added by an adder circuit and are further processed by a comparator, thereby generating digital signals. Forward-voltage-falling characteristics of the individual diodes used in the full-wave rectifier circuits are set to 0.3 V, and a threshold of the comparator is set to 0.6 V.

    摘要： A vibration gyro sensor is constructed as follows. Namely, a detecting piezoelectric/electrostrictive element 12, which detects displacement generated in a direction perpendicular to a direction of vibration of a vibrator 2 when the vibrator is rotated, is provided on a detecting section. The detecting section is constructed by an integrated fired product made of ceramics together with the vibrator 2 and a support base 4. The detecting section is constructed by a first plate-shaped section 6 which is more thin-walled than the vibrator 2 and which has its principal surface extending in the direction of vibration. The piezoelectric/electrostrictive element 12 is formed in an integrated manner on the first plate-shaped section 6 in accordance with a film formation method. Further, a thin-walled second plate-shaped section 8, which is provided for decreasing rigidity in the direction of vibration and facilitating the vibration for the vibrator 2, is formed in an integrated manner so that its principal surface extends in the direction perpendicular to the direction of vibration. Accordingly, it is possible to obtain the vibration gyro sensor made of ceramics having excellent sensitivity, in which the characteristics of the vibrator are scarcely affected by an ambient magnetic field, processing or machining can be easily performed, and the electric characteristics can be advantageously adjusted.

    摘要： A piezoelectric/electrostrictive (P/E) device includes at least one actuator section secured to thin plate sections with an adhesive. The actuator section includes a multilayered member including at least three actuator films, each of which include a P/E layer and electrode films. One or more holes or recesses are formed in portions of the thin plate sections on which the P/E elements are formed. The electrode films contact upper and lower surfaces of respective P/E layers and alternately extend to opposite surfaces thereof. End surface electrodes electrically connect an electrode film that contacts one of the P/E layers and an electrode film that contacts another one of the P/E layers. The end surface electrodes are electrically connected to terminals which are provided on a surface of an outermost layer of the P/E layers, and which are separated from one another by a predetermined distance.
