Inventor: KAI FUJIO
IPC: B65G65/20
Filed: 1986-02-21
Abstract: PURPOSE:To prevent the meandering and derailing of a traveling body, by monitering the wear of the traveling wheel utilizing the signal of a traveling distance detecting pulse transmitter and corrected position detector, thereby detecting the traveling deviation based on an distance between strikers and real traveling distance, and making an alarm if it is judged that abnormality is generated.

Abstract: PURPOSE:To obtain an electrifying member almost inhibiting deterioration by ozone, NOx, etc., and excellent in durability by incorporating a leuco base into a layer of an electrifying member into which substances generated by using an electrophotographic device penetrate. CONSTITUTION:A low resistance elastic layer 2b contg. electrical conductive carbon dispersed in silicone rubber is molded around a core metal 2a in 3mm thickness and a high resistance layer 2c is formed by dip coating in about 15mum thickness with a compsn. based on methoxymethylated nylon mixed with a proper amt. of a leuco base by using methanol.
