    摘要: This invention provides an ultrasonic motor using a bolt-tightened Langevin type torsional vibrator as a stator. The stator produces a vibrational energy to be converted into a rotational energy for a rotor contacted with the stator. The rotor is provided between a piezoelectric actuator and the torsional vibrator so that the contact state between the rotor and the torsional vibrator is controlled either one of loose contact and tight contact therebetween. According to the present invention, since the piezoelectric actuator is slidingly combined to the rotor, the rotation energy is not applied to the piezoelectric actuator and thus the life time of the actuator becomes long.

    摘要: A transducer is comprised of a piezoelectric ceramic cylindrical vibrator vibrating radially, and a sheet provided on an outer peripheral surface of the cylindrical vibrator and including a fiber reinforced composite material with fibers oriented only in the direction of central axis of the cylindrical vibrator. Non-piezoelectric cylinder consisting of Al alloy or Mg alloy may be useable instead of the sheet. Another type of transducer includes a cylindrical piezo-transducer vibrating radially, a cylindrical sound radiator with the central axis coincident with the cylindrical piezo-transducer, and a bending coupler provided at a predetermined interval on end surfaces of the two cylinders and coupling the cylindrical piezo-transducer and the cylindrical sound radiator. Other type of transducer is comprised of a cylindrical piezo-transducer vibrating radially, an outside cylindrical sound radiator with its central axis coincident with the central axis of the cylindrical piezo-transducer which contains the piezo-transducer therein, and a coupler extending radially from an outer peripheral surface of the cylindrical piezo-transducer to an inner peripheral surface of the cylindrical sound radiator, thereby coupling both the two.

    摘要: A trapped-energy mode resonator is obtained by forming conductive patterns on sheets of ceramic material and then laminating the ceramic material to obtain a resonator wherein a pair of central electrodes oppose one another through a central portion of the ceramic and peripheral electrodes oppose one another through peripheral portions of the ceramic, with the central and peripheral electrodes not overlapping one another. The distance between the central electrodes is shorter than the distance between the peripheral electrodes, with the central electrodes being embedded within the ceramic and the peripheral electrodes being either embedded within or formed on the surface of the ceramic.
