Title: Focus correcting mechanism
Inventor: KUBOTA TAKASHI
IPC: G02B7/02
Filed: 1985-03-14
Abstract: PURPOSE:To correct the focus accurately and automatically by arranging a focus correcting mechanism, which consists of a focus correcting actuator using the thermal expansion characteristic of a fluid, on the optical axis of an optical system. CONSTITUTION:A focus compensating actuator 11 consists of a tank 11a which has a cylindrical section and is formed into a ring shape, an operating fluid 11b packed in the tank 11a, cylinder holes 11d provided in several positions on the tank 11a, and pressing moving pieces 11c fitted to cylinder holes 11d. End face projected to the outside of moving pieces 11c are brought into contact with the side face of a condenser lens holder 2a holding a condenser lens 2. If the ambient temperature of the optical system rises and the focus position of an objective lens 1 is moved from a point (a) to a point (b), the operating fluid 11b packed in the focus compensating actuator 11 is expanded to press the condenser lens holder 2a in the direction of an arrow A along an optical axis O against the force of a restraining spring 13, thus allowing the focus position to coincide with the point (b).

Inventor: NOGUCHI FUMIO
IPC: A43B13/14
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To enable a golfer to develop the muscles on an inner side, to correct the bad habit of a sway or the like by immediate perception of centroid move ment and to early learn a correct golf swing by manufacturing golf lesson shoes by mounting shoe soles on the outer side of the shoes as one component by means of screws and internal threads. SOLUTION: The golf lessen shoes are manufactured by mounting the shoe shoes 2 on the outer side of the shoes 1 as one component by means of the screws 3 and the internal threads 4. At the time of a golf lesson, the golfer removes the shoe soles 2 on the outer side of the shoes 1 by loosening the screws 3 by means of a screw driver and makes a swing so as to horizontally maintain the shoes 1. The golfer is then able to make the ideal swing of himself preventing the centroid from escaping outside from the inner side of both feet. When the force on the inner side of the feet is removed in this state, the centroid moves to the outer side and the shoes l incline. The point is that the golfer is able to immediately perceive the movement of the centroid by this inclination. The use of rails, etc., in place of the screws, etc., is possible as well.  The shoes are applicable to bowleg correction, etc.

Abstract: PROBLEM TO BE SOLVED: To ensure the lock without holding a ball in the lock position by preventing the rotation of a locking body mounted on a device body by a ball moved from a stable position, and retaining the slightly opened state of a hinged door by the elastic force of the groove of the locking body. SOLUTION: When an earthquake occurs, a ball 9 moves forward from the rear end chamber of a vibration area A and laterally moves at the front edge thereof. The front part of the vibration area A is extended sideward in the inclined front edge, and the ball 9 laterally moves into the front part extended sideward. According to this, the locking part of a locking body is never lifted up even if a hinged door 91 touches against the tip side inner wall of an opening 7a according to the opening directional movement, and the groove of the locking part is contracted, so that the locking part reaches an opening end 7b through the throttled part 7c of a locking tool 7. When the force received from the vibration return of the earthquake is less than the locking retaining force in the step in this state, the hinged door 91 is not released, and the hinged door 91 is locked and retained in the state having a clearance.

Title: Magnetron type sputtering device
Inventor: SHIRAISHI YASUSHI
IPC: C23C14/35
Filed: 1990-03-05
Abstract: PURPOSE:To make improvement in the effective utilization rate of a target by disposing plural rotating magnet pairs on the rear side of the target at the distances varying from the central axis of the target. CONSTITUTION:The secondary electrons released from the target 13 impressed with a negative potential 11 are moved by receiving the influence of a magnetic field 15 formed by revolving two sets of the rotating magnet pairs 12 disposed at the distances varying by 1/3 the radius and 2/3 the radius from the central axis 10 of the target. Particularly the magnetic lines of force having the component parallel with the surface of the target 13 cause the cycloid motion of the secondary electrons on the target and, therefore, the ionization of Ar is accelerated and Ar ions are created. The Ar ions collide against the target 13 which is a cathode and drive out the target material, thereby depositing the target material onto a semiconductor substrate 17 on a substrate holder 16 and forming the thin film. Since the erosion of the target is generated along the magnetic field at this time, the erosion regions 14, 14A corresponding to double components are formed and, therefore, the effective utilization rate improves.
