摘要： An ultrasonic motor is proposed comprising a vibrator (101, 103) that vibrates by a high frequency drive voltage applied thereto, a sliding member (104) driven by frictional contact with the vibrator, pressurizing means (108, 109, 110) for pressurizing the vibrator to the sliding member, a base (102) to which the vibrator is fixed, a vibrator support member (105) holding the base, and coupling means for coupling the vibrator with the vibrator support member. The coupling means includes the base (102), a rolling member (106) that freely moves the base to the vibrator support member in a pressurizing direction (A) of the pressurizing means, and an urging member (107) that urges the rolling member in a direction (B) perpendicular to the pressurizing direction of the pressurizing means.

摘要： A control apparatus of a vibration actuator performs control of the vibration actuator using a control amount calculated using both of a first deviation (101) which is a difference between a command value generated by command value generation unit (105) and a relative position measured by position detection unit (117), and a gain (103) changed in accordance with a second deviation (102) which is a difference between a target position (106) and the relative position, so as to reduce the gain in accordance with reduction of the second deviation.

摘要： The invention relates to a multi-aperture imaging device comprising an image sensor, a single-row array of optical channels arranged next to one another, wherein each optical channel has an optic for imaging a sub-region of an object region on an image sensor region of the image sensor, and a beam deflection device for deflecting a beam path of the optical channels. The multi-aperture imaging device comprises an actuator device for generating a relative movement between the image sensor, the single-row array and the beam deflection device, wherein the actuator device is arranged in such a way that it is arranged at least partially between two planes, which are spanned via sides of a cuboid, wherein the sides of the cuboid are arranged in parallel to one another, as well as in relation to a row extension direction of the single-row array and a part of the beam path of the optical channels between the image sensor and the beam deflection device. A volume of the cuboid is minimal and nevertheless comprises the image sensor, the single-row array and the beam deflection device.

摘要： An inertial drive is disclosed, comprising a length-changeable actuator element (1), a frame element (4) with a support section and with a deformation section, against the contact surfaces of which the actuator element bears, wherein the deformation section has an articulation section (13), a flat spring element (5) which is arranged on the deformation section and has a friction section (3) at the free end thereof, and a friction body (2), which can be driven, in mechanical contact with the friction section. A change in length (S) of the actuating element causes a rotatory movement (D) of the deformation section about the articulation section, which movement is transmitted via the spring element to the friction section for driving the friction body which can be driven.
