摘要： In an optical disc fabricating apparatus, when the disc substrate is lowered from the tip of a disc inserting portion at a center pin down to a disc supporting portion, a disc urging portion of an alignment lever is pressed by a disc substrate, to be thus pushed in toward an inner periphery and a sheet urging portion is pushed out toward an outer periphery, so as to press the inner peripheral surface of a cover sheet so that both of the cover sheet and the disc substrate are urged in an alignment direction. Thus, it is possible to eliminate play generated between the inner peripheral surface of the cover sheet and the outer peripheral surface of a sheet inserting portion and play generated between the inner peripheral surface of the disc substrate and the outer peripheral surface of the disc inserting portion.

摘要： A method and apparatus for transferring a workpiece quickly and which can handle a variety of workpieces even of different outside sizes, and can accurately position workpieces. Workpieces on a transfer surface are adjusted in position to maintain an interval between the workpieces at a certain value. Along the transfer surface are disposed two belts on which are provided first and second holders raised above the transfer surface and which contact the workpiece at its front and rear edges. The holders, which are separately formed on the belt, cooperate with each other to hold the workpieces. The apparatus is also provided with a driving force which is able to change the rotational phase between the two belts. By changing the phase between the belts, the interval between the holders in the transfer direction can be varied in accordance with the size of the workpiece to be transferred.

摘要： In a method for inspecting a magnetic disk cartridge, the state, with which an adhesive agent has been applied as an annular layer onto a flange of a center hub in order to adhere a magnetic disk body and the flange of the center hub to each other, is inspected. A collimated light beam is irradiated to a cross section of the layer of the adhesive agent, which cross section is taken in the radial direction of the center hub, from a direction which is parallel to the surface of the flange and which is perpendicular to the cross section of the layer of the adhesive agent. The collimated light beam has a beam diameter such that the whole cross section may be included in the beam diameter. The amount of the collimated light beam, which has passed through the region in the vicinity of the flange, is detected. The area of the cross section of the layer of the adhesive agent is calculated from the detected amount of the collimated light beam, which has passed through the region in the vicinity of the flange. Thereafter, the amount of the adhesive agent, which has been applied onto the flange, is investigated from the results of the calculation.

摘要： A magnetic disc cartridge includes a casing formed of upper and lower shell halves mated together, a disc-like recording medium supported for rotation in the casing and a liner fixed to each of the inner surfaces of the upper and lower shell halves by ultrasonic welding by use of an ultrasonic welding horn. The liner has an outer contour defined by an outer peripheral edge, a central opening defined by an inner peripheral edge, and a slit-like cutaway portion defined by a pair of linear edges extending between the outer peripheral edge and the inner peripheral edge. The ultrasonic welding horn is provided with a welding pattern in the form of a protrusion pattern formed on a welding face thereof over the entire welding area in which the ultrasonic welding horn is brought into contact with the liner, and the liner is welded to the inner surface of the shell half over the entire area of the liner along the welding pattern.

摘要： A torsion spring having a central coiled portion and a pair of resilient arms projecting from the coiled portion in different directions is incorporated in a workpiece so that the coiled portion is fitted on a support pin on the workpiece and the arms are engaged with first and second engagement portions on the workpiece. A center pin is inserted into the coiled portion of the torsion spring, and the coiled portion is held by attraction of an attracting portion provided around the center pin. A pair of forming pins are moved relative to the center pin in directions perpendicular to the longitudinal axis of the center pin to abut against the respective arms of the torsion spring and deflect them. Then, the torsion spring held by the attracting portion is moved to bring the end of the center pin into abutment against the top end of the support pin, and the attracting portion is moved toward the support pin so that the center pin is pushed away from the coiled portion and the support pin is inserted into the coiled portion, and the arms of the torsion spring are released from the forming pins and brought into engagement with the first and second engagement portions on the workpiece.

摘要： In the configuration wherein a metal thin plate is pressed by dies 2 to a punch 1 having unload channels 1b and 1c which elongates from one end of the punch 1 to the position corresponding to a tab-bent portion 60a of a workpiece 60, the edge portions of the punch 1 are chamfered as curved faces R or formed into an obtuse angle of 90.degree. or more. After the metal thin plate is bent along the punch, the angle of the edge portions is formed by pressing the metal thin plate toward the punch, and the workpiece 60 is unloaded in the direction along which the dimensions of the unload channels 1b and 1c formed on the punch 1 can be shortened.

摘要： In an ultrasonic welding method and apparatus for molded resin materials, molded resin materials, whose corresponding parts to be welded to each other have been superposed one upon the other, are held between a welding horn and a molded material receiving section, and the corresponding parts of the molded resin materials are welded to each other with an ultrasonic welding process. A plurality of parts of the molded material receiving section are supported independently of each other by a plurality of receiving section support members. When the corresponding parts of the molded resin materials are welded to each other, the supporting forces of the plurality of the receiving section support members are adjusted independently of each other such that a welding pressure applied by the welding horn onto each pair of the corresponding parts of the molded resin materials may become equal to a predetermined value. The corresponding parts of the molded resin materials are thus accurately joined to each other without any adverse effect occurring from fluctuations in the thicknesses of the molded resin materials.

摘要： A magnetic disk cartridge which prevents center cores from biting into each other when the cores are stacked during manufacture, and which can be produced at low cost with improved productivity. The center core includes an engagement hole formed in the central portion thereof, which includes a rising edge portion in the edge portion thereof. The height of the rising edge portion is determined in such a manner that, in order to prevent the flange inner peripheral corner portion and bottom outer peripheral corner portion of the center cores from contacting each other along the peripheries thereof when the cores are stacked, the rising edge portion of the engagement hole of one center core is allowed to contact the bottom surface portion 4b of the adjacent core. Also, the radius of curvature of the bottom outer peripheral corner portion is made greater than the radius of curvature of the flange inner peripheral corner portion.
