IPC: G11B7/135
Filed: 1983-07-06
Abstract: PURPOSE:To reduce aberration, to enlarge a moving range of an objective lens and also to attain low cost and miniaturization by moving the objective lens in a diverged luminous flux irradiated from a semiconductor laser. CONSTITUTION:A light irradiated from the semiconductor laser 3 passes through a half mirror 7, is made incident to the objective lens 1 while the state of diverged luminous flux is kept and stopped at the lens 1, and a minute spot is formed on a disc 5. The light is reflected on a signal face of the disc 5, and the image is formed on a photodetector by means of the half mirror 7. Since the light is focused onto the disc at all times by means of focus control in this case, even if the objective lens 1 moves to any position, the luminous flux returns along the original path at all times, the luminous flux separated by the half mirror 7 is formed at a position being conjugate to the semiconductor laser 3 to the half mirror 7 without fail and a normal signal obtained. When the ratio of the number of apertures of the object side and the image side of the objective lens 1 is selected large, no effect is caused on aberration.

Abstract: PURPOSE:To improve the feeling of riding and the stability of steering upon turning as well as high-speed straight running by a simple structure by a method wherein a ball joint and rubber bushes are arranged so that the tyre is turned into the direction of toe-in in case either one of side force, braking force, engine braking force and driving force is acting on the tyre. CONSTITUTION:When the side force acts on the tyre upon turning, a turning moment is generated about an axle 6 and the force end of the tyre is displaced inwardly by the horizontal component HF of the reaction F of a stabilizer due to the one-side bump while a wheel hub 18 is displaced into the direction of toe- in. When the engine braking force E acts on a wheel center W from fore side to aft side, the hub 18 is turned about the axle L and is displaced into the direction T of toe-in. When the braking force B acts on the grounding point G from the fore side to the aft side of the wheel, the tyre tries to turn about the axle M and the hub 18 is displaced into toe-in by the directions of the rubber bushes 19, 20. When the driving force K acts on the wheel center W from the aft side to the fore side, the tyre tries to effect toe-out, because the driving force K acts into the reverse direction of the braking force E, however, the hub 18 is displaced into toe-in about the axle L by the stoppers of the bushes 19, 10.
