Title: Tooth striking sound preventing structure for transmission
Inventor: SHIMOKAWA TADAO
IPC: F16D23/06
Filed: 1993-03-31
Abstract: PURPOSE:To provide an effective means for preventing or reducing the wear of a friction damper in a transmission provided with the friction damper to prevent the generation of tooth striking sound. CONSTITUTION:At the idle time, a separate journal 21 is strongly energized inward by a spring member 24 so as to be pressed to a stopper 22. At this time, friction torque is applied to an output gear 5 from a friction damper 25 so as to prevent the generation of tooth striking sound from the output gear 5. At the time of high speed or the like, on the other hand, the rotating speed of the output gear 5 becomes high, and the separate journal 21 is displaced in the direction of being separated from the friction damper 25 against the energizing force of the spring member 24 by centrifugal force. At this time, the lip part of the friction damper 25 is separated from the separate journal 21. Wear is not therefore generated to the lip part of the friction damper 25, so that its durability can be heightened in large degree.

Filed: 1989-03-29
Abstract: PURPOSE:To make it possible to remove the microscopic foreign substances adhered to the surface by a method wherein a pulse laser beam is made to irradiate on the surface of a solid body. CONSTITUTION:A pulse laser beam (a) is made to irradiate on the surface of a solid material on which microscopic foreign substances are adhered. The density of laser energy varies according to the type of the laser beam (a), but 0.1 to 1.5J/cm<2> or thereabout is considered suitable, and the more the pulse laser beam (a) becomes shortwave beam, the more the microscopic foreign substances 2 becomes easily absorbed, and the effect of the above-mentioned operation is remarkable. To be more precise, the temperature of the microscopic foreign substances 2 suddenly changes by the irradiation of the pulse laser beam, and thermal stress works on the working force between the foreign substances and the substrate. As a result, the foreign substances adhered to an Si wafer, an Si thermally oxidized film and the Si oxidized film, on which a microscopic processing is conducted, can be removed.

Abstract: PURPOSE:To obtain an objective lens driving device having high tracking sensitivity by providing a tracking coil wound in nearly square tubular form in circumferential direction of a circumference that having the axial line of a supporting shaft as a center and at the same time, providing a closed magnetic circuit for the tracking coil. CONSTITUTION:The end (a) of the third yoke 23A, 23B that constitute the second magnetic circuit is inserted into the hollow part of tracking coils 29A, 29B. When driving force is generated in the tracking coils 29A, 29B, twisting force is applied to a cylindrical part 18a. Accordingly, secondary resonance frequency becomes low if rigidity of the cylindrical part 18a is not strengthened. When tracking coils 29A, 29B are fixed to collar parts 18c, 18d, twisting force is not applied to the cylindrical part 18a. Accordingly, secondary resonance frequency can be increased and the cylindrical part 18a can be constituted with resin and eddy current does not generate when driving a focus coil 28. Thus, effective length that generates driving force in tracking direction can be made long and sensitivity of tracking can be increased.
