While applying the semi-conductivity rubber cement on the production

摘要

PROBLEM TO BE SOLVED: To improve size stability for a long term, electric resistance stability ozone resistance, and heat resistance under various environments by constituting this transcription belt for an electronic apparatus by forming a semiconductive rubber layer on a seamless reinforcing layer constituted out of continuous yarn. ;SOLUTION: This transcription belt is constituted of a seamless reinforcing layer 21 consisting of continuous yarn, a semiconductive rubber layer 22 formed on the reinforcing layer 21, and a resistance adjusting layer 23 formed on this semiconductive rubber layer 22. Because it contains an elongation preventing reinforcing layer therein, the permanent elongation is extremely small when it is used under tension within breaking elongation. Further because the rubber layer 22 is contained, restoring force due to elasticity acts, an effect preventing meandering acts, and permanent strain is prevented and simultaneously meandering is also prevented. As for the material of the yarn constituting the reinforcing layer 21, natural fiber such as cotton or hemp, synthetic fiber such as polyester or nylon, monofilament or multifilament such as metallic inorganic fiber can be used.;COPYRIGHT: (C)1999,JPO
