摘要： The invention relates to an ultrasonic motor comprising a plate-shaped piezoelectric ultrasonic actuator (2) and a friction element (5) arranged on a side surface thereof, wherein the connection line (V) through the friction point and the focal point (S) of the ultrasonic actuator defines an operating direction, and a perpendicular plane intersecting the ultrasonic actuator defines an operating plane (W). A holder (6) has two force inlet sections (7) in order to move the holder and thereby the ultrasonic actuator in a direction parallel to the operating direction, and to press same against an element to be driven. The force inlet sections, preferably based on permanent magnets (8, 9) are each arranged in the operating plane and laterally next to and at a distance from the the ultrasonic actuator, and the intersection point (SP) of the connection line (V) with the operating plane (W) either coincides with the focal point (S) or lies between the focal point and the side surface having the friction element.

摘要： The actuator (2) comprises a piezoelectric actuator element (4), which is 18 connected to an adjusting element (12) for exerting an adjusting movement in the adjusting direction (14). For the transmission of a deflecting movement of the actuator element (4), a housing (6) is formed with a variable-shape displacer (8) enclosed therein. During operation, a deflecting movement of the actuator element (4) is transmitted to the displacer (8), so that the latter is deformed and, as a result of the deformation, performs a yielding movement. The housing (6) in this case forms a guide for the displacer (8), so that the yielding movement of the displacer (8) is oriented in the adjusting direction (14). The adjusting element (12) is also connected to the displacer (8), so that the yielding movement of the displacer (8) is transmitted to the adjusting element (12).

摘要： An image pickup apparatus, including: an observation unit configured to observe an object; a detector configured to detect whether or not a user observes the object through use of the observation unit; and a controller configured to control an actuator, the actuator being configured to drive at least a part of an photography optical system and being capable of performing a first operation and a second operation different from the first operation, the second operation being an operation for maintenance of the actuator, wherein, when the detector detects that the user does not observe the object through use of the observation unit, the controller causes the actuator to perform the second operation.

摘要： The invention relates to a piezoelectric rotary drive (1) for a shaft (2), comprising a piezoelectric actuator (3), a deformable frame (4), which can be frictionally coupled to the shaft by means of a coupling segment (5) in order to achieve a stick-slip drive, and a loading means (6) in order to apply a preloading force to the coupling segment and/or the actuator and/or the shaft. In order to simplify production and assembly, the loading means is designed as a leaf spring, which extends substantially in a plane, preferably along a straight line, in the relaxed state.

摘要： An electromechanical actuator (100) includes an oscillation resonator (10) having the shape of a rod. The oscillation resonator (10) is divided by a dividing plane (15) that is not parallel to the longitudinal direction of the oscillation resonator (10) into a first resonator portion (10A) and a second resonator portion (10B). At least the first resonator portion includes electromechanical means which, when activated, are configured to generate a 3-dimensional acoustic bulk wave are with a mode shape asymmetric with respect to the dividing plane (15).

摘要： A motor (3) includes a pressing member (110) pressing a vibrator (104) onto a contacting member (101), first (105) and second (107) holding members respectively holding the vibrator and a transmission member (111), which transmits pressing force by the pressing member to the vibrator, and a coupling member (116) coupling the first and second holding members. The vibrator and the contacting member move by vibrations occurring in the vibrator. The coupling member includes a rolling member (108a, 108b) moving the first and second holding members in a pressing direction of the pressing member, and an urging member (109), which is held by the second holding member, urging the first and second holding members in parallel with a moving direction of the vibrator and the contacting member. The rolling member is sandwiched between the first and second holding members, and abuts against the first holding member on a center side of the vibrator in the moving direction.

摘要： A pump (1) includes a vibrating plate (15) that has a central part (21), a frame part (22), and connecting parts (23 to 26), a piezoelectric element (16) that is stacked over the central part (21) and configured to cause flexural vibrations to occur concentrically from the central part (21) to the connecting parts (23 to 26), and an opposed plate (13) that is stacked over the frame part (22) and positioned facing each of the connecting parts (23 to 26) with a spacing therebetween. The vibrating plate (15) has such a resonant mode that an antinode occurs in each of the central part (21) and the connecting parts (23 to 26). The opposed plate (13) has, at positions facing the connecting parts (23 to 26), a plurality of channel holes (39 to 43) through which a fluid flows.
