Title: The Innovations of Tadashi Mimura
Introduction
Tadashi Mimura is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of electrophotography, holding a total of 4 patents. His work focuses on developing photoconductors that enhance the quality and durability of printed images.
Latest Patents
Mimura's latest patents include a photoconductor for electrophotography. This invention relates to photoconductors that exhibit excellent electrical properties, which are not significantly affected by environmental changes or repeated use. These photoconductors demonstrate remarkable durability during repeated printing, allowing for the production of large quantities of high-quality output images. The design includes a conductive substrate and a photoconductive film, which consists of multiple charge generation and transport layers. Each layer contains a phthalocyanine compound, serving as both a charge generation agent and a charge transport agent, with a higher concentration of the charge generation agent in the upper layer compared to the lower layer.
Another significant patent is the process for preparing a metal-free phthalocyanine. In this process, phthalonitrile, an alkali metal or an alkali metal compound, and a hydrogen donor compound are heated in an organic solvent. This synthesis results in a partially hydrogenated alkali metal phthalocyanine, which is then treated with a dealkalizing agent to substitute hydrogen, yielding high-purity metal-free phthalocyanine. This compound can be utilized as a charge-generating substance to create an electrophotographic photoconductor that is highly sensitive to near-infrared rays and produces high-quality images.
