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： 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： An electric motor has a rotor having an end portion and a recessed portion formed at the end portion. A rotational shaft is mounted to the rotor. A stator covers an outer peripheral portion of the rotor and forms a magnetic field that generates a torque around the rotational shaft to thereby rotate the rotational shaft and the rotor. A bearing rotatably supports the rotational shaft and is entirely spaced-apart from the end portion of the rotor in an axial direction of the rotational shaft. A slider is slidably mounted around the rotational shaft and supports rotation of the rotational shaft about a rotational axis thereof. The slider is interposed between the bearing and the rotor so that a portion of the slider is entirely contained in the recessed portion of the rotor and the remaining portion of the slider is disposed in the space between the bearing and the rotor and in contact with the bearing.

摘要： A control portion always monitors a present-position signal from a position sensor and monitors whether the present position of a moving body is a desired position, or not (Step 101). In the case where the control portion detects that the present position of the moving body reaches the desired position, the control portion generates a stop command signal and gives the stop command signal to an oscillation drive circuit (S102). Then, the control portion checks whether overshooting occurs, or not (S103), and in the case where the control portion judges that overshooting occurs, the control portion retains a stop command signal as it is for a stop command retaining time t (S104). After the stop command retaining time t elapses, the control portion gives a reverse command signal to the oscillation drive circuit to conduct reverse operation (S105). After Step S105, the control is returned to Step S101 and the above operation is repeated. Then, in the case where the control portion judges that overshooting does not occur in Step S103, position correcting operation is completed.
摘要翻译：控制部分总是监视来自位置传感器的当前位置信号，并且监视移动体的当前位置是否为期望位置（步骤101）。在控制部检测到移动体的当前位置达到期望位置的情况下，控制部产生停止指令信号，并向振荡驱动电路送出停止命令信号（S102）。然后，控制部检查是否发生过冲（S103），在控制部判断为过冲的情况下，控制部按照停止指令保持时间t保持停止指令信号（S104）。在停止命令保持时间t过去之后，控制部分向振荡驱动电路给出反向指令信号以进行反向操作（S105）。在步骤S105之后，控制返回到步骤S101，并重复上述操作。然后，在步骤S103中控制部判断为不发生过冲的情况下，完成位置校正动作。
