摘要： An ultrasonic motor has a longitudinal-torsional composite transducer, a stator constituted by an ultrasonic vibrator sandwiching the transducer, and a rotor urged against the stator. The stator excites longitudinal-torsional ultrasonic vibrations to rotate the rotor by a frictional force. The motor includes a vibration adjusting rod for matching resonance frequencies of longitudinal and torsional ultrasonic vibrations of the stator with each other.

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： 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： 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： A cell search method is disclosed in which autocorrelation patterns are subtracted from a correlation value profile. When carrying out a cell search with respect to a correlation value profile, the peak timing of a first base station is first detected and the scrambling code of this base station is identified. A path search process is then carried out using this timing and scrambling code to detect timings at which multipath occur. Autocorrelation patterns that center on the obtained frame timings and autocorrelation patterns that center on multipath are next generated and a process is performed to subtract these autocorrelation patterns from the correlation value profile. This process enables the rapid detection of peak produced by a second base station.
