    摘要： An optical switch for use as a shutter for intercepting or passing light signals, such as beam lights, including a piezoelectric actuator attached at one end thereof to a base plate and at its other end to an optical shielding object for intercepting or passing over light beams, a mirror installed on a location close to the place where the piezoelectric actuator is attached to the base plate to reflect passed light beams, and the piezoelectric actuator being coupled to a source of energy. The light signals are intercepted or passed by the movement of the object due to modifications of the piezoelectric actuator, and the passed light signals are reflected by the mirror and detected by an optical detector.

    摘要： An optical scanner for scanning light signals, such as light beams, including an electrostrictive element attached at one end thereof to a base body, a convex mirror fixed to the other end of the electrostrictive element, a driving circuit for changing a voltage applied to the electrostrictive element, and an emitter for emitting a light beam to the surface of the convex mirror in a direction different from the modified direction of the electrostrictive element. When the applied voltage to the electrostrictive element changes by the driving circuit during reflecting light beams on the convex mirror surface, the electrostrictive element is modified according to the applied voltage. Simultaneously light beams are scanned over a wide range, even if the modified volume is small, due to continuous change of deflection angles of beams according to the radius of the curvature of the convex mirror.

    摘要： A piezoelectric transducer having electrodes formed on both surfaces has a piezoelectric base molded as a curved plate which can converge sound fields of acoustic waves at an arbitrary point and which can reduce noise or reverberation in a lateral direction which otherwise occur due to unnecessary vibration. At least one of the electrodes is divided concentrically. A material having a small electromechanical coupling factor K.sub.p in the lateral direction is used for the piezoelectric material, preferably porous PZT.

    摘要： A toner cartridge includes a toner receptacle that houses toner, a plurality of stirring members housed in the toner receptacle, a plurality of gears meshing with each other on outside of the toner receptacle, and a phase display section. The stirring members are arranged next to each other in the toner receptacle and rotate to stir the toner. Each of the stirring members has a scraper that scrapes off the toner adhering to an inner surface of the toner receptacle. The gears rotate to rotate the stirring members in an interlocked manner with each other. The phase display section shows a meshing position of the gears so that the gears mesh with each other at a position where a phase difference along a rotating direction of the stirring members occurs between the scrapers of the stirring members that are next to each other.
