摘要： Low and high impedance thickness mode vibration portions are integrally laminated. Each vibrator portion comprises electrode layers between which a piezoelectric layer polarized in the direction of thickness is interposed. In each vibrator portion, every other electrode layer is connected to respective common external terminals. These common external terminals are of either four-terminal construction consisting two pairs, one pair for the low impedance mode vibrator portion and the other pair for the high impedance thickness mode vibrator portion, or three-terminal construction in which one of each pair are united together into a common terminal. Difference between the impedances is set on difference in the number of electrode layers and/or on difference in dielectric constant between the piezoelectric layers.

摘要： One driver having external electrodes arranged over both surfaces of a piezoelectric ceramic plate polarized in the direction of its thickness, and one generator having two mutually opposed interdigital electrodes on one or both surfaces of a piezoelectric cermic plate and alternateley polarized in the direction of its length between the electrode fingers of the interdigital electrodes are formed combined in alignment in the direction of the length of the piezoelectric ceramic plate. Alternatively, the driver and generator may be formed in alignment in the direction of the width of piezoelectric ceramic plate. By applying a low voltage to this piezoelectric ceramic transformer from the driver at a resonance frequency of a longitudinal vibration of second order mode of the piezoelectric ceramic plate, a high voltage can be picked up from the generator. Here, through connection of the input terminals and output terminals at the nodes of vibration, failure due to vibration of lead wires can be prevented, thereby obtaining a compact and slim transformer element that provides high reliability. A plurality of drivers and generators may also be employed, and in addition, an interdigital electrode may be used in the driver as well as in the generator.

摘要： A piezoelectric ceramic transformer includes a piezoelectric plate, a pair of driving sections, and a power generating section. The piezoelectric plate is made of a piezoelectric ceramic material and has a long plate-like structure. The pair of driving sections are arranged at two end portions of the piezoelectric plate and formed by alternately stacking a plurality of piezoelectric ceramic layers polarized in a direction of thickness of the piezoelectric plate and first internal electrodes, and cause longitudinal vibration by a driving voltage applied to first and second input terminals. The power generating section is arranged at a central portion of the piezoelectric plate in a lengthwise direction thereof and polarized in the lengthwise direction of the piezoelectric plate, and generates an output voltage at a first output terminal by the longitudinal vibration transmitted from the driving sections.

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.
