Title: Lamination type magnetic head
Inventor: OJI MASAAKI
IPC: G11B5/147
Filed: 1990-11-26
Abstract: PURPOSE:To improve the contact state between a magnetic head and a recording medium even in case of wear of metallic thin films by constituting a head substrate of >=2 kinds of materials varying in wear characteristics. CONSTITUTION:A laminate 1 is formed by laminating magnetic metallic thin films 6a, 6b consisting of, for example, 'SENDUST(R)', amorphous Co, etc., via an insulating thin film 7. Further, the laminate 1 is pinched by the substrates consisting of two kinds of the substrates varying in the wear characteristics; for example, the head substrate 3 having hard characteristics, such as, for example, ceramics, and the head substrate 2 having the softer characteristics than this head and is further laminated with the magnetic metallic thin films 6... on the side having the higher tendency to wear. Then, the head substrates on both sides of the laminate wear earlier than the conventional substrates even if the magnetic head wears unevenly and, therefore, the magnetic recording medium 8 at the time of traveling is deformed as shown in Fig. and the spacing between the laminate 1 does not increase in the past. The nearly tight contact state is thus maintained.

Title: Image forming device
Inventor: KIMURA SHIGEO
IPC: G03G21/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent electric discharge products from attaching to a developer carrier and to always output a uniform image without density irregularity by rotating the developer carrier of a developing means which is not used in a second image forming mode for a prescribed time. SOLUTION: In a monochromatic mode, the electrifying action of an electrifier 2 and the rotation of a photoreceptor drum 1 are executed. However, when the black sleeve 4Bks of the black developing unit 4Bk used for developing is continuously rotated in a long time the electric discharge products attach to only one part sides of the stopped developing sleeves 4Ya, 4Ma and 4Ca of the other developing units of three colors 4Y, 4M and 4C other than the unit 4Bk. Then, the sleeves 4Ya, 4Ma and 4Ca of the units 4Y, 4M and 4C which are not used are rotated in one second every time that image forming actions as many as 10 sheets are executed in the monochromatic mode.  By periodically rotating the developing sleeves of the developing units which are not used for the image forming action in such a way, a large amount of electric discharge products are prevented from attaching to only one part sides of the surfaces of the developing sleeves.
