    摘要： An angular rate detector includes an oscillator having a first terminal to which a drive voltage is applied, a second terminal where a signal occurs having a given phase displacement with respect to a signal appearing at the first terminal during a resonance of the oscillator and a third terminal where a signal occurs having a phase which changes in accordance with an angular rate. An oscillator is provided for producing an alternating signal which corresponds to the drive voltage applied to the first terminal in accordance with the signal appearing at the second terminal. A frequency multiplier responsive to a signal which corresponds to the oscillation frequency of the oscillator produces a clock pulse having a frequency higher than the oscillation frequency. A phase difference pulse signal is produced having a duty cycle which changes in accordance with a phase difference between the signal occurring at the third terminal of the oscillator and either the signal applied to the first terminal or the signal occurring at the second terminal. A counter is provided for counting the clock pulses during a time interval when the phase difference pulse signal assumes either a high or a low level.

    摘要： An electrical circuit for reliably starting the oscillation of an oscillator comprising a cylindrical piezoelectric body on which an exciting electrode, a feedback electrode which causes an oscillation, and an electrode for detecting an angular rate are mounted. The electrical circuit includes an exclusive OR gate for detecting a phase difference between an exciting voltage and a voltage developed at the feedback electrode, a circuit for integrating an output voltage from the gate and a band pass filter having its resonant frequency shifted in proportion to a voltage from the integrating circuit. The band pass filter is effective to provide an automatic adjustment of a phase difference of a voltage, which is actually fed back to the exciting electrode, with respect to a voltage developed at the feedback electrode. In this manner, if the natural frequency of the oscillator is offset from a reference value, it is assured that a phase difference between the exciting voltage and the voltage which is actually fed back to the exciting electrode be equal to 360.degree.. The electrical circuit also includes an oscillation starter circuit which increases the gain of a positive feedback loop including the filter for a given time interval immediately after the turn-on of the power.

    摘要： A process and apparatus for building a green tire. The process includes mounting a carcass, in the form of a cylinder, around a green tire building machine having left and right shoulder formers with radially expandable bead locking mechanisms. The left and the right shoulder formers are each moved together into an idle movable state where the shoulder formers are allowed to move freely in an axial direction either closer or farther from each other. The bead locking mechanisms are radially expanded so as to lock the beads in a set position on the outer circumferential surface of the carcass outside the respective bead locking mechanism. Once the beads are locked, each of the shoulder formers are placed in a driven movable state for driving the respective shoulder formers toward each other thereby narrowing the distance between the beads so as to shape the carcass into a toroidal form.

    摘要： A case has parts storage openings through a top plane. Terminals protrude above the plane and extend downward through the case to a bottom plane, where they are bent to conform to the bottom plane. Interconnections of the terminals in the bottom plane provide the wiring pattern necessary for the creation of an LC filter. LC combination parts are made using a coil wound on a coil support with a capacitor secured to the top surface of the coil support. The coil part of the LC combination parts are inserted into the parts storage openings of the case, to secure the coils rigidly in place. The coils and capacitors are affixed to the terminals above the top plane. The resulting rigid support of the LC combination units provides stable and accurate filter characteristic in a compact package. The interconnections of the terminals in the bottom plane permits observation of the connections to permit manual inspection or the use of pattern recognition hardware and software for robotic sorting and assembly.
