Abstract: A chassis has rotatably mounted thereon a magazine for accommodating a plurality of disks as positioned upright. A playback portion and an insertion-discharge portion are arranged respectively inside and outside the magazine radially thereof. Roller units for holding and transporting the disk are provided between the insertion-discharge portion and the magazine and between the magazine and the playback portion, respectively. The roller units are coupled together by a train of gears and driven by a motor M3 to rotate in directions opposite to each other. Control apparatus is disposed within the device main body for energizing the motor M3 for a specified period of time before the magazine is rotated to rotate the roller units in directions to draw the disk into the magazine.

Abstract: Each of two coupling members is formed in an abutting end lace thereof with a recessed portion for accommodating a gasket and a retainer therein, and the recessed portion has a retainer holding hollow cylindrical portion formed centrally on a bottom surface thereof and provided on an end face thereof with an annular projection for clamping the gasket. The gasket comprises a small portion and a large portion having a greater outside diameter than the small portion. The retainer is attached to the cylindrical portion of the coupling member with which the gasket small portion is in contact.

Abstract: A disk playback device comprises a magazine having a plurality of disk spaces for accommodating disks in an upright position, and an inlet-outlet portion provided externally of the magazine for permitting the disk to pass therethrough into the magazine from outside a device main body. Sensors for detecting loading of the disk into the magazine are disposed beside a path of travel of the disk and connected to a processor for storing information as to presence or absence of the disk in each of the disk spaces. The device main body has an automatic loading mode wherein an empty disk space having no disk accommodated therein is searched for based on the information stored in the processor as to presence or absence of the disk, the magazine is rotated to position the empty disk space as opposed to the inlet-outlet portion and the operation to search for an empty disk space is repeated again after completely loading a disk into the empty disk space.

Abstract: A method is provided for tightening up threaded members with proper tightening torque free of unequivalent tightening. In tightening a plurality of threaded members by drive means, the amount of tightening and tightening torque of each threaded member are detected as the members are progressively tightened, and when the tightening amount of each member has reached a value within a specified range, the difference in tightening torque between the threaded members is checked as to whether it is within a predetermined range.

Abstract: A fluid control apparatus comprises a mass flow controller, two on-off valves disposed at the inlet side of the controller and three on-off valves disposed at the outlet side of the controller. At the inlet side, a main fluid on-off valve is positioned on a purge fluid on-off valve, and at the outlet side, a vent on-off valve is positioned on a vacuum suction on-off valve, with a main passage on-off valve further positioned on the vent on-off valve.

Abstract: A control system for a disc playing device which facilitates selection of playing of discs by assigning identification codes comprising consecutive numbers to all disc holding grooves of a magazine. A memory of a microcomputer has a first storage area for storing the identification code of the magazine groove positioned as opposed to a disc insertion-discharge portion or playing portion, and a second storage area for storing the identification code of the groove accommodating the disc to be played. The direction of rotation of the magazine is determined by an arithmetic procedure based on the two identification codes stored in the first and second storage areas and on the difference in position between the insertion-discharge portion and the playing portion around the center of the magazine.

Abstract: A magazine controlling method is disclosed for smoothly stopping a disk storing magazine. According to the method of the invention, the rotational speed of the disk storing magazine in rotation is reduced upon the magazine reaching a position a small distance short of a predetermined stop position, and the magazine is then stopped at the predetermined stop position.
