    摘要: A camera using films each having a development processing solution in a solution accommodating bag includes rollers feeding photographed film outside of the camera or into an accommodating chamber, a piezoelectric press member held between an electrode and an elastic member also serving as an electrode presses photographed film and spreads development processing solution in the solution bag over an entire exposing portion. A piezoelectric member vibrated by AC voltages applied to the electrode and elastic member reduces a frictional force of the film caused by the press member. The processing solution is heated by vibrating the press member to generate heat. A camera using films each having a development processing solution accommodated in a solution bag includes a follower roller disposed on the upper side of the film, an ultrasonic motor composed of a vibrator on the lower side of the film, a temperature sensor detecting temperature of the ultrasonic motor, a peripheral temperature measuring circuit for detecting a peripheral temperature and a control circuit controlling drive of the ultrasonic motor based on the results detected by the temperature sensor and the peripheral temperature measuring circuit. The ultrasonic motor also serves as a film feed unit for feeding photographed film outside of the camera or into an accommodating chamber, a press unit for pressing photographed film and spreading development processing solution in the solution bag over an entire exposing portion and a heating unit for heating development processing solution before spreading.

    摘要: In an ultrasonic motor, an elliptical vibration is generated by combining a longitudinal primary resonance vibration resulting from an expansion and a contraction of a vibrator in a direction of a central axis and a torsional secondary resonance vibration or a torsional tertiary resonance vibration resulting from twisting around the central axis. A dimension ratio of a rectangle of the vibrator is chosen such that a resonance frequency of the longitudinal primary resonance vibration and a resonance frequency of the torsional secondary resonance vibration or the torsional tertiary resonance vibration match. The vibrator includes a plurality of regions in a surface orthogonal to the central axis, and deformations of the regions adjacent to each other along the direction of the central axis are mutually different. The vibrator expands and contracts in a direction orthogonal to a polarization direction thereof.

    摘要: With the invention, both a longitudinal vibration mode and a flexural vibration mode are independently detected, or only the longitudinal vibration mode is detected, without using a special device. The invention provides an ultrasonic motor including electromechanical transducers for driving, electromechanical transducers for vibration detection, and an ultrasonic vibrator in which, by supplying two-phase alternating voltages with a predetermined phase difference and predetermined driving frequency to the electromechanical transducers for driving, two different vibration modes are simultaneously generated to produce a substantially elliptical vibration at an output. It is possible to independently detect both the longitudinal vibration mode and the flexural vibration mode with the electromechanical transducers for vibration detection.

    摘要: An ultrasonic motor capable of simultaneously generating a plurality of vibration modes efficiently generates each vibration mode so as to stably obtain high motor power. The ultrasonic motor an ultrasonic vibrator and a pressing unit. The ultrasonic vibrator includes an electromechanical converting element that generates a substantially elliptic vibration at an output end of the ultrasonic vibrator by simultaneously generating two different vibration modes by applying a first alternating-current voltage of a first phase and a second alternating-current voltage of a second phase to the electromechanical converting elements, wherein the first and second alternating-current voltages have a predetermined phase difference and predetermined driving frequencies. The pressing unit is configured to press the output end of the ultrasonic vibrator against a driven body. The output end of the ultrasonic vibrator is pressed against the driven body by a pressing force that causes mechanical resonant frequencies in the two different vibration modes to substantially match each other.
