    摘要: The vibrator includes, for example, a triangular prism shaped vibrating body. On each of three side faces of the vibrating body, piezoelectric elements are formed respectively. The vibrating body makes bending vibration by giving a driving signal to one or two piezoelectric elements. The vibrator is used in a vibratory gyroscope. In this case, for example, one piezoelectric element is used for vibrating the vibrator. When a rotating force is applied to the vibratory gyroscope, a Coriolis force is exerted to produce output voltages on the remaining two piezoelectric elements corresponding to the rotational angular velocity.

    摘要: A vibrating gyroscope includes a vibrating body which is formed into, for example, a square loop. A section of the vibrating body is formed into, for example, a square. Driving piezoelectric elements are formed on upper and lower faces of one piece of the vibrating body. Detecting piezoelectric elements are formed on outer and inner side faces of a piece of the vibrating body whereon the driving piezoelectric element is formed. On a piece adjoining the piece whereon the driving piezoelectric element is formed, the detecting piezoelectric elements are formed. By applying a signal to the driving piezoelectric elements, the vibrating body is subjected to bending vibration, and by measuring an output voltage of the detecting piezoelectric elements, a rotational angular velocity is detected.

    摘要: In a mounting board, two through-holes are formed which are used for inserting both ends of a supporting member for a vibrator. On a surface of the mounting board, a ground conductor pattern is formed. In the ground conductor pattern, two portions of arcs, where the ground conductor pattern is removed, are formed on respective peripheries of the two through-holes. Furthermore, on the mounting board, two connecting conductor patterns are formed on surfaces of portions defined by the two through-holes and so on, so as to extend from the ground conductor pattern. Both ends of the supporting member for the vibrator are respectively inserted into the two through-holes and soldered to two connecting conductor patterns.

    摘要: A support base of an angular velocity sensor is supported rotatably at one end, and the support base is vibrated by a piezoelectric element. By this vibration, a known rotational angular velocity is applied to the angular velocity sensor. For example, a difference of two output signals of the angular velocity sensor is measured. This difference of the output signals is detected in synchronism with phases which differ from each other by 180.degree., in two synchronous detection circuits. The detected signal is smoothed in smoothing circuits, and further, amplified in amplifying circuits. An output signal of the amplifying circuit is composed in a variable resistor as a composite circuit. Meanwhile, from the output signal of the amplifying circuit, the output signal of the variable resistor and a signal corresponding to the known rotational angular velocity are subtracted.

    摘要: The invention is based on a thin-film semiconductor FET device. A field plate electrode for producing an electric field is formed on a channel-protecting film above the end of the gate electrode that is on the side of an offset region. Stable transistor characteristics can be maintained for a long time with the field plate electrode voltage set to a low value. The drain electrode is coated with a film of an anticorrosion metal. Where an integrated circuit with a high device density is fabricated from semiconductor devices of this construction, the drain electrodes are effectively prevented from being corroded.

    摘要: The detection circuit includes a first synchronism detection circuit for synchronous detection of an input signal. A second synchronism detection circuit synchronously detects the input signal separately from the first synchronism detection circuit. A phase-shifting circuit outputs differently phased signals to the first synchronism detection circuit and the second synchronism detection circuit. A first smoothing circuit smooths the output of the first synchronism detection circuit. A second smoothing circuit smooths the output of the second synchronism detection circuit. A composite circuit adds the outputs of the first smoothing circuit and the second smoothing circuit. Even when a drift component is contained in the input signal, the detection circuit will output a predetermined output signal in which the drift component is suppressed.
