Title: Apparatus for producing magnetic recording medium and production of magnetic recording medium
Inventor: ITO JOTA
IPC: H01F41/20
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To improve the orientability of magnetic particles constituting a magnetic layer by installing a permanent magnet in a position opposite to a cooling can. SOLUTION: A tape-like nonmagnetic base 4 which is a work travels successively toward a take-up roll 3 rotating counterclockwise at a constant speed within a vacuum vessel 1 of a continuous take-up type vacuum vapor deposition device, in which vessel a vacuum degree of 10<-2> Pa, etc., is maintained. The cooling can is cooled to, for example, -20 deg.C to prevent the deformation of the base 4 by the heat at the time of vapor deposition. The apparatus is provided with an electron gun 10 as a heating means and an electron beam 11 is cast onto the ferromagnetic material 7 in a crucible 6, by which the material is heated and melted. The vapor flow X evaporated from the crucible 6 is deposited by evaporation on the base 4 and is formed as the magnetic layer. The permanent magnet 12 is installed in the position opposite to the cooling can 5.  The permanent magnet 12 impresses the magnetic field in the longitudinal direction of the base 4 right after the formation of the magnetic layer on the magnetic layer of the ferromagnetic metallic thin film on the nonmagnetic base 4. The orientational property of the magnetic particles constituting the magnetic layer is resultingly improved.

Title: Image forming device
Inventor: KAWABUCHI YOICHI
IPC: G03G21/04
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of enhancing the working efficiency, while saving energy, through the number of image forming times is controlled for every group of users. SOLUTION: In a CPU, when an ID card is pulled out of a card reader, after copying is completed and the ON edge of a card pull-out signal is received (Yes in the step S501), an APO(automatic power-off) time of 'one minute' is set (the step S503). On the other hand, when the ID card is inserted into the oart reader, to make a copy and the ON edge of a card insertion signal is received (Yes in the step S505), an APO time corresponding to a department code is retrieved from a department information management table stored in a control RAM, because the department code is read from the ID card, at the time of inserting it and then, the retrieved APO time is set as the APO time (the step S508). Thus, when a copying permission state is obtained, as the APO time, a time longer than an APO time of one minute in a copying inhibition state (for instance, 30 minutes) is set.

In such a way, while improving improving a film forming speed, the coagulation of the lubricant is decreased. As a result, the drop-out being a recording and reproducing defect is decreased remarkably.
