Abstract: A magnetic-transfer method comprising the steps of: initially DC-magnetizing a transfer-recipient disc in a circumferential direction, by applying a magnetic field to the transfer-recipient disc in the circumferential direction thereof; bringing initially DC-magnetized transfer-recipient disc and a master disc into close contact with each other, on the top side of the master disc a magnetic layer including a great number of protrusions that configure a magnetic pattern being formed, ratio t/b of thickness t of the magnetic layer to circumferential length b of the protrusion being from 0.5 to 4.

Abstract: A magnetic transfer method for performing magnetic transfer is provided wherein magnetic transfer is performed by conjoining and holding in surface-to-surface contact by a holder a transfer master medium, on which transfer data is borne, and a slave medium, to which the transfer data is transferred, and by applying a transfer magnetic field to the transfer master medium held in the holder by a magnet disposed facing to a recordable surface of the slave medium. The holder and the magnet are held movable relative to each other in the direction of the normal to the recordable surface of the slave medium. The distance between the holder and magnet as seen in the direction of the normal is adjusted when magnetic transfer is performed.

Abstract: A one-way damper includes a cylindrical housing, a viscous fluid contained within the housing, a rotor rotatably disposed in the housing, and a valve body. The rotor has a center part for forming a rotational center, and a control wall extending radially outwardly from the center part for dividing an inside of the housing. The control wall has a distribution path. The valve body has a holding part for holding the center part, and a free edge part extending from one side of the holding part for opening-and closing the distribution path. A seal member prevents the viscous fluid from leaking between the housing and the rotor.

Abstract: A magnetic transfer apparatus for transferring patterned information formed on a surface of a master disk to a magnetic recording medium as a slave disk placed in intimate contact with the surface of the master disk by applying a magnetic field to the disks, which comprises: a magnet; a first holder for holding the master disk and the slave disk; and a second holder facing the first holder, the first holder being supported by a supporting member, the magnet being disposed on only an outer side of the second holder, and the second holder being formed solely of a lid.

Abstract: A spacer includes a first cam having an inclined cam surface and a second cam having an inclined cam surface. The overall length of the two cams can be changed by contacting the cam surfaces together to move the cams relative to each other.

Abstract: A photo film cassette includes a spool for winding the photo film thereabout, and a cassette shell for containing the spool in a rotatable manner. The spool has first and second ends disposed to appear outside the cassette shell. To manufacture the photo film cassette, a cassette shell with the spool is retained while confronting a drive shaft with the first end and confronting a support shaft with the second end. The support shaft is slid in an axial direction, to support the second end. The spool is displaced via the support shaft to a braked state where rotation of the spool is blocked. The spool is displaceable between the braked state and a released state. The drive shaft is rotated and slid while the spool is in the braked state, to engage the drive shaft with the first end in a key-engaged manner. After the drive shaft is engaged with the first end, the spool is displaced from the braked state to the released state.

Abstract: A filament-type trimming apparatus comprises a reel case including a main body and a bottom member, a cord reel housed in the reel case and which is wound with a nylon cord, plural stoppers on a lower surface of the cord reel and on an inside of the bottom member and which become engaged when the cord reel is pressed downward by a coil spring, a mechanism for releasing a centrifugal force of the cord reel and which is provided between the cord reel and the bottom member and which comprises radial guide grooves and balls arranged inside the guide grooves, and plural stoppers on an upper surface of the cord reel and on an inner surface of the reel case respectively and which become engaged when the cord reel is pressed upward resisting against the pressing force of the coil spring. A boss is provided inside the reel case main body at its center and to which the coil spring is fixed.

Abstract: Automobile windows on both sides of the vehicle are curved inwardly and arcuately toward the top of the compartment and are made separate from the doors and slidably abutted at least at the front edges on the support frame for the windshield, at least either of the side windows being made openable by sliding them upwardly. When opened, they are accommodated in recesses formed for that purpose in the roof that covers a middle part of the ceiling space above the car body. Alternatively, the windows extend toward each other until their upper edges overlap along the central longitudinal line of the ceiling space above the car body, the windows being made slidable relative to each other, one over the other in a superposed relation, so that either window, when opened, is partly or fully superposed, as desired, parallelly over or under the other.
