摘要： Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only. When a stray field in a direction horizontal in relation to the recording medium is applied, the magnetic field acting on the recording medium is removed by the cover of the device comprising a magnetic component.

摘要： A photo film cassette includes a spool core (13) on which photo film is wound in a form of a roll. A cassette shell (3, 4) contains the spool core in rotatable fashion. In each of a pair of disks (16, 17), a bearing hole (16a, 17a) is formed. The disks are secured to first and second ends of the spool core, and regulate edges of the photo film. To produce at least one kind of disk, a continuous sheet (27, 78, 88, 162, 171, 215) of thermoplastic synthetic resin is partially masked with a mask plate (48, 87, 160, 161, 170). A portion of the sheet emerging out of the mask plate is heated at temperature higher than a softening point of the sheet. The emerging portion is subjected to vacuum/air-pressure forming, so as to form a disk-like portion (20) in the sheet. The bearing hole and a contour of the disks is cut in the disk-like portion, to produce the disks.

摘要： A label sticking apparatus has a suction drum with at least three holding-sticking units mounted at constant intervals on the periphery thereof so as to be movable in radial directions of the suction drum. The suction drum is rotated intermittently by a constant amount so as to feed and stop the holding-sticking units at a label feeding station, a positioning station and a sticking station which are disposed around the suction drum in this sequence. Labels are seriatim peeled from a label tape and held on a distal end of the holding-sticking unit at the label feeding station. At the positioning station, positioning of each label is performed by a positioning head having a centering pin and a pair of angular position correction pins. At the sticking station, the holding-sticking unit is pushed through an eccentric cam radially outward from the suction drum toward a work-piece, to press and stick the label held on the holding-sticking unit onto the work-piece.
