Title: Kuniki Seino: Innovator in Electrophotography
Introduction
Kuniki Seino is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of electrophotography, holding a total of 7 patents. His work has advanced the technology used in electrical charging apparatuses and electrophotographic processes.
Latest Patents
One of his latest patents is an electrical charging apparatus for electrophotography. This apparatus includes a confronting electrode formed by a metallic plate, a heat-resistant electrically insulative member covering the surface of the confronting electrode, and an exciting electrode in the form of a thin wire fixed to the surface of the heat-resistant electrically insulative member. A power source applies a high voltage AC current between the confronting electrode and the exciting electrode, while a control electrode in the form of a mesh is provided to confront the exciting electrode.
Another significant patent is the electrophotographic copying method with a residual charge erasing step. This method involves a transparent conductor backed photoconductor layer positioned in virtual contact with a conductor backed dielectric layer. During the process, a first voltage is applied between the conductors to produce an electrostatic latent image on the dielectric layer. The erasing step, applied after the transfer of the latent image, includes positioning the photoconductor and dielectric layers in virtual contact, illuminating the full surface of the photoconductor layer, and applying a second voltage of opposite polarity to the first voltage.
