IPC: G03G15/08
Filed: 1989-07-03
Abstract: PURPOSE:To simplify or eliminate a recessed and projecting part forming stage for the surface of the base substance of a sleeve in production by forming a film containing crystalline graphite on the surface of a developer carrier. CONSTITUTION:In a developing device in which development is performed by restraining developer with magnetic force, the film 4 containing the crystalline graphite is formed on the surface of the developer carrier. A metallic drawing material is used as the base substance 1 of the developer carrier. Namely, paint containing the crystalline graphite is applied to the base substance 1 so that the surface roughness of the base substance 1 may be maintained without executing surface working to the base substance 1. Thus, the surface working to the base substance 1 is eliminated and the developer carrier excellent in endurance stability is obtained.

IPC: B61L25/02
Filed: 1982-09-29
Abstract: PURPOSE:To recognize exactly a movement of a cab by frequency-dividing a radio wave from a wayside, and thereafter, sending it back. CONSTITUTION:A sine wave signal of frequency F1 generated by a wayside device 3 is sent to a wayside loop coil 4 through a demultiplexer 7. When a cab coil 17 is coupled with the wayside loop coil 4, the frequency F1 is detected by a cab loop coil 2. That which amplitude-detects this signal becomes an electric power source of the cab coil. At the same time, this signal is converted to a pulse, and thereafter, is frequency-divided, and three kinds of signals of frequencies f1, f2 and f3 are generated. One of those signals is transmitted from the cab loop coil 2. The wayside device 3 checks a shift state of frequency and discriminates the cab coil.

IPC: H01L21/60
Filed: 1994-07-22
Abstract: PURPOSE:To realize high speed operation without sacrifice of bonding quality by braking the lowering operation of a capillary tool immediately before application of bonding load to a capillary tool. CONSTITUTION:A wire is passed through a capillary tool 42 held by a bonding arm which is then oscillated by means of a motor thus connecting aboard with a chip mounted through the wire.
