摘要： Contact pressures between a driven member and an ultrasonic vibrator are balanced, making the driving characteristics in the forward and reverse directions uniform, and the driven member is driven with high driving efficiency. The invention provides a pressing mechanism of an ultrasonic vibrator for pressing sliding members against a driven member, the sliding members being provided at two or more positions corresponding to antinodes of a standing wave vibration of the ultrasonic vibrator. The pressing mechanism includes a pressing member configured to make contact with the ultrasonic vibrator at two or more positions corresponding to nodes of the standing wave vibration of the ultrasonic vibrator; and pressing-force adjusting units configured to adjustably apply pressing forces, which press the sliding members against the driven member, to the pressing member at two or more separate positions in the direction of a gap between the two or more nodes of the standing wave.

摘要： There is provided a piezoelectric actuator which includes a piezoelectric material layer in which, a portion sandwiched between a first electrode and a second electrode is an active portion, and a vibration plate which is arranged on a surface of the piezoelectric material layer. The piezoelectric material layer is polarized in a direction parallel to a direction of thickness thereof, and a direction of polarization of a central portion in the active portion and a direction of polarization of an edge portion excluding the central portion, in the active portion are mutually opposite. Accordingly, even when a drive voltage is low, it is possible to increase sufficiently an amount of deformation of the piezoelectric actuator.

摘要： An electromechanical motor includes a rail to be moved, a dry, non-lubricated, sliding bearing for the rail, and driving members imposing a mechanical driving force on the rail. The bearing has two rail contacting portions. A first portion contacts the rail for obstructing displacements of the rail in a first direction transverse to a main extension of the rail. The first portion also obstructs rotation of the rail around an axis parallel to the main extension. The second portion is arranged for obstructing displacements of the rail in the first direction transverse to the main extension, while allowing at least a minor movement of at least one of rotation of the rail. The motor allows for mechanical flexibility at certain selected positions and ensures immobility at other selected positions, in order to reduce the impact of externally induced displacements, torques and rotations at critical places in the motor.
摘要翻译：机电电动机包括待移动的轨道，用于轨道的干燥，非润滑的滑动轴承以及在轨道上施加机械驱动力的驱动构件。轴承具有两个轨道接触部分。第一部分接触轨道，用于在横向于轨道的主延伸部的第一方向上阻挡轨道的位移。第一部分还阻碍导轨围绕平行于主延伸部的轴的旋转。第二部分布置用于阻挡轨道在横向于主延伸部的第一方向上的位移，同时允许轨道的至少一个旋转的至少轻微的移动。电机允许在某些选定位置处具有机械灵活性，并确保在其他选定位置处的不动作，以减少外部诱发的位移，转矩和转动在电机关键位置的冲击。
