摘要： An optical switch has an input section for inputting a light beam and movable optical members each comprised of a piezoelectric actuator for inputting the light beam from the input section and for individually switching an optical path of the light beam. Each of the piezoelectric actuators has a piezoelectric body for undergoing oscillating movement and a movable body frictionally driven by oscillating movement of the piezoelectric body. A driving control device drives the piezoelectric bodies of the piezoelectric actuators and controls positions of the piezoelectric bodies to switch the optical path of the light beam. An output section outputs the light beam from the piezoelectric actuators.

摘要： A low cost portable dosing apparatus enables the dispensing rate to be changed while enabling solution to be continuously dispensed to the body. The solution to be dispensed into the body is stored in a tank unit. A pump unit pumps the solution from the tank unit into the body of the patient. A controller controls pump unit operation. The tank unit, pump unit, and controller are attached to a wrist strap so that they can be easily connected and disconnected from each other. A compact, thin ultrasonic motor with high output per unit size drives the pump unit. A smaller pump unit is thus available, improving the portability of the apparatus. The ultrasonic motor is also substantially free of misoperation resulting from exposure to magnetic fields because the ultrasonic motor is not magnetically driven. Reliability is therefore improved.

摘要： An ultrasonic motor has a vibrating body polarized in a given direction. The vibrating body comprises a first piezoelectric body and a second piezoelectric body laminated to the first piezoelectric body in a preselected direction generally parallel to the polarized direction. Each of the first piezoelectric body and the second piezoelectric body has a first polarized portion and a second polarized portion. The first polarized portion of the first piezoelectric body is aligned in the preselected direction with the second polarized portion of the second piezoelectric body. The second polarized portion of the first piezoelectric body is aligned in the preselected direction with the first polarized portion of the second piezoelectric body. A movable member is frictionally driven by a combination of a stretching vibration and a bending vibration generated by applying a driving signal to the first polarized portions of the first and second piezoelectric bodies or to the second polarized portions of the first and second piezoelectric bodies.

摘要： An ultrasonic motor is provided that is improved in reliability of a self-oscillator circuit constituted by the ultrasonic motor itself and high in efficiency. In a case of driving with one standing wave, the resonant point of a vibration mode used for driving is made lower than a resonant point of another vibration mode that is same in form as this vibration mode but different in node position. Furthermore, oscillation is caused between two resonant points. Where using two standing waves, oscillation is caused at a higher frequency than any of the two resonant points.

摘要： An ultrasonic motor has a piezoelectric element driven by application of a voltage thereto to undergo expansion and contraction. A vibrating body is vibrationally driven by the expansion and contraction movement of the piezoelectric element to thereby produce standing waves. A moving body is frictionally driven by the standing waves of the vibrating body. Power transmission projections apply a frictional force to the moving body to thereby frictionally drive the moving body in accordance with the standing waves. The power transmission projections are disposed only every preselected number of wavelengths at intermediate positions between loops and nodes of the standing waves, the preselected number being a natural number.
