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 sensor unit is provided for detecting a physical quantity with improved accuracy while maintaining acceptable detection limits. The sensor unit includes at least three three-axis sensors for three-dimensionally detecting the magnitude and direction of a physical quantity wherein the three sensors are disposed in one plane. Each three-axis sensor includes: an operating member; a supporting base having a hollow with the operating member being located at the center of the hollow; and a flexible plate having a piece of piezoelectric material in contact with at least one pair of electrodes and extending across the hollow at an end of the supporting base, the operating member being suspended at the center of the hollow by the flexible plate. The three three-axis sensors are assigned the X, Y, and Z directions, respectively, of a three-dimensional coordinate system so that the physical quantity applied from the outside is detected for each component in the X, Y, and Z directions independently of each other.
