摘要： Provided is a control apparatus of a vibration-type actuator for generating an elliptical motion of contact portions by a common alternating current including a frequency determining unit for setting a frequency of the alternating current. The frequency determining unit sets the frequency of the alternating current for changing an ellipticity of the elliptical motion, within a frequency range such that ellipticity changing frequency ranges set for the vibrators are overlapped, and the ellipticity changing frequency ranges are set for the vibrators as frequency ranges between an upper limit and a lower limit, such that the lower limit is a maximum resonant frequency at a time of changing the ellipticity, and the upper limit is larger than the lower limit and is a maximum frequency for the relative movement of the driving member.

摘要： A plurality of drive sections (20) are defined by forming a plurality of slits (28) in a plate-shaped member (24). Then, a plurality of piezoelectric layers (26) are formed in the drive sections respectively by depositing particles of a piezoelectric material onto the plate-shaped member. Subsequently, after forming individual electrodes (27) on the piezoelectric layers respectively, the drive sections are bent in a direction orthogonal to a plane direction of the plate-shaped member. Thus, there is provided a method of easily producing a piezoelectric actuator including the drive sections which are bent-shaped and on which the piezoelectric layers are formed respectively.

摘要： In order to provide a driving device that can be made more compact and shorter in height, a driving mechanism of a driving device according to the present invention includes: a flex movement member 1 that exhibits flex movement when excited by electronic control, and a first fixing member 14 for fixing a part of the flex movement member 1, both ends of which sandwich the part fixed by the fixing member 14 and bend. A first elastic member 12 and a second elastic member 22 are connected to the both ends of the flex movement member 1. The flex movement of the both ends of the flex movement member 1 causes distortion or bending in the first elastic member 12 and the second elastic member 22, so that a first frictional member 12 and a second frictional member 23 each serving as a contact section in contact with a lens barrel 5 move in a direction different from the flex movement direction of the both ends of the flex movement member 1. Thus, the lens barrel 5 is driven.

摘要： In manufacturing electromechanical drive elements, vibration properties are defined in a test environment. These properties are found to give a good operation when being arranged in a motor. Two flexural vibration modes are defined. One is an s-mode connected to an element being strapped at two supports at respective outer portions. The s-mode have three nodal points. The other vibration mode is an ϵ-mode (112) connected to an element being strapped at the supports and at a drive pad arranged at a middle portion (H l)- The ϵ-mode (112) has one nodal point (155) at each side of the middle portion (111) and the middle portion (111) has a stroke amplitude that is smaller than stroke amplitudes at portions (113, 115) between the middle portion (111) and the nodal points (155). An average of the resonance frequencies of the s-mode strapped at two and three points, respectively, differs from and the ϵ-mode (112) resonance frequency by less than 25%.

摘要： This invention relates to a vibration wave driving apparatus including an electro-mechanical energy conversion element (3) that is sandwiched and fixed between elastic members (1,2,5), in which a flange-shaped elastic member (5) is provided between the electro-mechanical energy conversion element and one of the elastic members (1,2). When a driving vibration is applied to the electro-mechanical energy conversion element, a vibration element excites bending vibrations and those bending vibrations allow out-of-plane bending vibrations to be excited in the flange-shaped elastic member. Since a rotor is brought into contact with the third elastic member (5) sandwiched between the elastic member and the electro-mechanical energy conversion element, the size of the vibration wave driving apparatus can be reduced. In addition, since a travelling wave produced by the bending vibration of the vibration element and a travelling wave produced by the out-of-plane bending vibration of the third elastic member are generated at the frictional surface of the vibration element, the output of the vibration wave driving apparatus can be improved.
摘要翻译：本发明涉及一种振动波驱动装置，其包括夹在和固定在弹性构件（1,2,5）之间的一个凸缘形弹性构件（5）之间的电 - 机能能转换元件（3）机电能量转换元件和弹性元件（1,2）之一。当对机电能量转换元件施加驱动振动时，振动元件激发弯曲振动，并且这些弯曲振动允许在凸缘状弹性构件中激发平面外的弯曲振动。由于转子与夹在弹性构件和机电能转换元件之间的第三弹性构件（5）接触，所以可以减小振动波驱动装置的尺寸。此外，由于在振动元件的摩擦面产生由振动元件的弯曲振动产生的行波和由第三弹性构件的面外弯曲振动产生的行波，因此，可以提高振动波驱动装置。
