Vis-a-vis discharge nonuniformity measuring method, discharge nonuniformity observation manner and the discharge nonuniformity

摘要

PROBLEM TO BE SOLVED: To provide a discharge irregularity observation method for obtaining a member making use of discharge or a charge phenomenon by the discharging which is developed on the basis of knowledge obtained by measuring a microscopic electrical property and in which irregularity in density or a void is not occurred.;SOLUTION: A discharge irregularity observation device is provided with a transparent electrode substrate 7 with a semi-transparent or transparent electrode 2 on a surface facing a roller member 1 installed so that an electrode surface can be brought into contact with or separated from a surface of the roller member. Then, a potential difference is provided between the transparent electrode substrate 7 and a metal core of the roller member. Discharge light occurring due to the potential difference provided between the transparent electrode substrate 7 and the roller member 1 is photographed by a photographic device 3 installed on a back side of the transparent electrode substrate and discharge irregularities occurring in the roller member are observed.;COPYRIGHT: (C)2012,JPO&INPIT
