Title: Resin material having good electrical conductivity and friction characteristics
Inventor: SUZUKI OSAMU
IPC: C08L67/00
Filed: 1983-08-31
Abstract: PURPOSE:To provide the titled material having excellent electrical conductivity and friction characteristics useful for a video cassette reel, rotating sheet feeding parts of a copier, etc., by incorporating carbon black and lubricating oil into a thermoplastic resin. CONSTITUTION:The titled material is prepared by incorporating carbon black and lubricating oil into a thermoplastic resin (an acetal copolymer is especially preferable). The carbon black gives electrical conductivity and the lubricating oil gives lubricity to the composition. Although the incorporation of the carbon black tends to raise the friction coefficient and increase the wear of the thermoplastic resin, thus deteriorating its friction characteristics, the extent of deterioration can be greatly decreased by the addition of the lubricating oil, so that a resin material having both good electrical conductivity and good friction characteristics is obtained. Moreover, a bearing material which produces conductive bearings and is applicable to a bearing system wherein no static charge builds up on a shaft can be made.

IPC: G11B21/08
Filed: 1988-06-27
Abstract: PURPOSE:To prevent a head and a disk from flawing due to erroneous movement of the head by detecting that the head has traversed a track during a fine control. CONSTITUTION:On order to carry out a seek command, it is checked by a microprocessor 11 whether an FF 14 is set or not. That is, since there is a possibility of moving the head beyond a control range for holding a head position by an impact from the outside against the device, etc., this is decided by whether this FF 14 is set or not. Since this FF 14 is reset by the processor 11 due to entering the fine control, it is set by outputting a track crossing pulse under the fine control, so that this abnormal state can be detected. Consequently, when the FF 14 is set, since there is a discrepancy between a present head position stored in the processor 11 and an actual head position, the initialization of the head position is carried out.
