摘要:
A vibration actuator that is easy to manufacture and has good driving performance, and a lens-barrel and a camera provided with the same. The vibration actuator is provided with an oscillator that generates oscillations; and a relative movement member that is pressure contacts the oscillator, and moves relative to the oscillator due to the oscillation. Either a contact face of the oscillator with respect to the relative movement member or a contact face of the relative movement member with respect to the oscillator is a thermosetting resin film that is formed of polyamide-imide resin and fluororesin, and the other contact face is an anodic oxide film.

An oscillatory wave motor, a lens barrel, and a camera system are provided, which have long service lives and which are stable. An oscillatory wave motor includes an oscillator which generates oscillation on an elastic member in accordance with excitation of an electromechanical conversion element, and a relative movement member which is pressurized to make contact with the oscillator and which moves relative to the oscillator in accordance with the oscillation. The oscillatory wave motor has an epoxy resin film formed of silicon beads and an epoxy resin and which is formed on at least one of frictional contact surfaces of the oscillator and the relative movement member.

A component feeding apparatus for pitch-feeding taping components (1) to a component feed position (30), peeling a cover tape (1b) short of the component feed position (30) and taking out and feeding a component (5) from an accommodation portion (1c) at the component feed position (30), wherein the component is supplied stably in an appropriate posture to the component feed position (30). A slit (36) is formed in a shutter (35) capable of moving between a position at which the upper surface of the taping component (1) is covered and a position at which the component feed position is opened so that a cover tape (1b) peeled from the taping component (1) can be passed through the slit (36) and can be pulled up, and the peeling step of the cover tape (1b) and the pitch-feeding step of the taping component (1) can be separated from each other to prevent the component (5) from greatly moving and assuming an irregular posture inside the accommodation portion (1c).

An apparatus for automatically performing plural sequential spherical grinding operations on workpieces such as optical lenses includes a machine base, an index table mounted on the machine base for rotation about an axis, a plurality of chuck units supported by the index table at positions equally spaced about the axis for grasping respective work pieces, and a conveyor for sequentially moving the workpieces adjacent the index table. A positioning device is located adjacent the conveyor for positioning sequentially workpieces to be ground at a selected position on the conveyor. A transfer device is positioned adjacent the conveyor and the index table to sequentially grasp individual workpieces at the selected position and transfer such workpieces sequentially to respective of the chuck units as the index table is rotated about the axis. The chuck units grasp or chuck the respective workpieces. A plurality of grinding units are mounted on the machine base at positions above the chuck units. A plurality of workpiece feed units are mounted on the machine base beneath the index table at positions corresponding to and aligned with positions of respective grinding units. Each feed unit clamps a respective chuck unit, rotates the same, and moves the same upwardly from the index table toward the respective grinding unit.

A positioning device includes an X-direction slide table and a Y-direction slide table which are slidable in directions perpendicular to each other. Stops are adjustable as to their relative positions with respect to the slide tables to define accurate stop positions of the slide tables. Cams and levers shift the slide tables. Biasing devices bias the slide tables against the stops. A linear drive shifts at least one of the slide tables over a predetermined distance against the respective biasing device.
摘要:
The present invention provides an image forming device including: plural image formation sections, a second exposure section, a transfer body, a reading section and an identification section. Each image formation section includes a control section that controls a first exposure section to form an identification image of a color represented by color information in accordance with an image formation instruction. The second exposure section performs exposure onto a charged image-bearing body and forms an electrostatic latent image. An image is formed at the transfer body. The reading section reads an image. The identification section outputs to the plurality of image formation sections an image formation instruction and, on the basis of a duration from the output until the identification image is read by the reading section, identifies a position of the image formation section forming the image of the color instructed by the image formation instruction.
