Title: Chiyoji Hitomi: Innovator in Thermal Transfer and Liquid Crystal Technologies
Introduction
Chiyoji Hitomi is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the fields of thermal transfer and liquid crystal technologies. With a total of 2 patents, his work has had a considerable impact on modern technology.
Latest Patents
One of Hitomi's latest patents is for a thermal melt transfer color ink sheet. This innovative ink sheet is designed for making thermal transfer color recordings with high speed and resolution using a semiconductor laser beam. It comprises a support film coated with an opto-thermal conversion layer that generates heat by absorbing the laser beam. The overlying thermal melt transfer ink layer is engineered to ensure optimal performance, with the opto-thermal conversion layer being 5 micrometers thick or less, and having a laser beam transmittance of 5% or less in the wavelength region of 700 nm to 900 nm.
Another significant patent by Hitomi involves liquid crystal devices. This invention features a layer of fibers or filaments permeated with liquid crystal material. The layer is strategically located between electrodes, allowing an electric field to be applied across it. This configuration enables the variation of transmissivity of the liquid crystal/fiber composite, with the diameters of the fibers/filaments selected to reduce sensitivity to mismatches in the refractive indices of the liquid crystal and the fibers/filaments.
