摘要： An ultrasonic motor has a piezoelectric vibrator driven by a voltage signal to undergo expansion and compression movement. At least two elastic bodies are connected to opposite ends of the piezoelectric vibrator and are vibrationally driven by the expansion and compression movement of the piezoelectric vibrator. Each of the elastic bodies has at least one groove formed in a surface thereof for converting the expansion and compression movement of the piezoelectric vibrator into torsional vibration so that the elastic bodies generate a combination of longitudinal vibration and torsional vibration. A movable member is connected to the elastic bodies to be frictionally driven by the combination of longitudinal and torsional vibrations generated by the elastic bodies.

摘要： An ultrasonic motor comprises first piezoelectric oscillators alternately arranged with first polarized regions having a first direction of polarization and second polarized regions having a second direction of polarization opposite to the first direction of polarization. The first piezoelectric oscillators undergo bending vibration in a first direction upon input of drive signals having a same phase to the first polarized regions and the second polarized regions to thereby excite the first and second polarized regions. Second piezoelectric oscillators are laminated to the first piezoelectric oscillators in a second direction generally perpendicular to the first direction for undergoing elongation and contraction vibration in the first direction. When a driving signal is applied to the first and second piezoelectric oscillators a drive force is generated by a combination of the bending vibration of the first piezoelectric oscillators and the elongation and contraction vibration of the second piezoelectric oscillators.

摘要： A piezoelectric actuator has a base and a movable body disposed over a surface of the base for undergoing movement relative thereto. The movable body has a frame and at least one cantilever having a first end integrally connected to the frame and a second free end. A piezoelectric element is disposed on the cantilever for undergoing expansion and contraction movement in response to application of an alternating voltage to bring the second free end of the cantilever into and out of contact with the surface of the base to thereby move the movable body relative to the surface of the base. Spring members are connected to the frame of the movable body for regulating a direction of movement of the movable body relative to the surface of the base.

摘要： Disclosed is an ultrasonic motor whose output is improved by enhancing the exciting force of a vibration caused on a vibrating body having a rectangular portion. The ultrasonic motor includes the vibrating body having a piezoelectric element, and a moving body which contacts the vibrating body. The phases of two difference vibrations caused on the vibrating body are changed to make the moving direction of the moving body or the vibrating body itself variable by selecting whether to apply a drive signal to first electrodes provided at one side of the piezoelectric element or to apply a drive signal to second electrodes provided at a portion whose polarization direction differs from that of the first electrodes.

摘要： A method of optically coupling one end of an optical fiber to a waveguide formed on a substrate, such that an end portion of the fiber is fitted in a groove formed in the substrate. The groove is formed by forming a beam-shielding mask having a cutout, on the substrate such that the cutout is aligned with a part of the substrate in which the groove is formed, and by irradiating the above-indicated part of the substrate with a high-energy beam. Alternatively, the groove is formed by a cutting tool. An inclined end surface of the groove left uncut by the tool may be irradiated with a high-energy beam, through a beam-shielding mask which has a cutout aligned with the inclined end surface. The end of the optical fiber, which has a flat face or has a coned or hemi-spherical shape, is positioned for optical coupling with a portion of the waveguide which is exposed to the groove.
