Abstract: PURPOSE:To reduce the reciprocating mass, to decrease the noise in the sliding, and to improve the assembly work efficiency, by holding spheres with a circular groove provided to a shaft, and a circular groove provided to a keep plate made of a reinforced synthetic resin which is fixed to the upper side of the shaft. CONSTITUTION:In a crankshaft 14, a shaft 13 furnishing an oil hole 11 in the axial direction and a circular groove 12 on which spheres 9 slide, and a keep plate 17 made of a reinforced synthetic resin furnishing a circular groove 16 fixed to the upper side of the shaft 13 and spheres 9 slide on are provided. While spheres 9 are held between the circular grooves 12 and 16, the center axis L of both circular grooves is formed deflecting from the axial center M of the shaft 13. As a result, by making the shaft 13 and the like also of the reinforced synthetic resin, the major parts of the crank 10 can be formed of the reinforced synthetic resin, and the reciprocating mass can be reduced. And since a shaking between the spheres 9 can be suppressed by the elasticity of the keep plate 17 itself, a noise in the sliding can be reduced. Furthermore, since the number of parts can be reduced, the assembly work efficiency can be improved.

Filed: 1987-09-08
Abstract: PURPOSE:To improve the accuracy of an access by generating a tracking switch- off timing from a relative speed signal obtained from between a slider and a tracking actuator and from a speed command signal. CONSTITUTION:A relative speed detection means detects the relation speed between the slider and the tracking actuator 6, and outputs a result as a relative speed signal to a tracking OFF-timing generation means. The timing generation means, after confirming that this signal supplies a command to the slider to move, observes the relative speed between the tracking actuator 6 and the slider, and generates a tracking OFF-timing at a time when at least the relative speed in the accessing time comes zero or less. At this timing, a tracking switch 4 is turned off, and an output from a compensating amplifier 11 is transmitted to a drive circuit 5 so that a tracking position is locked. As a result, the accuracy of an access can be improved.

Filed: 1989-08-31
Abstract: PURPOSE:To lower rigidity partially by providing plural protruding parts in multi-stages through plural dent parts and providing the lower periphery of the protruding part in the uppermost stage with plural recessed parts formed circumferentially at specified spaces apart. CONSTITUTION:Three protruding parts 13-15 are formed in multi-stages at the periphery of a bumper body 11 through two annular dent parts 12. When compressive load acts upon the bumper body 11, each dent part 12 is crush- deformed, so that the respective protruding parts 13-15 are mutually brought into contact. When the respective protruding parts 13-15 start their compressive deformation, the protruding part 13 in the lowest stage is compressively deformed in the relatively flexible state while being enlarged radially. The protruding part 14 in the intermediate stage is compressively deformed in the flexible state, with one part of its upper end part being absorbed gradually into a recessed part 17. The rigidity of each protruding part is thus lowered partially.
