Title: Teiji Miura: Innovator in Liquid Crystal Technology
Introduction
Teiji Miura is a prominent inventor based in Suwa, Japan, known for his significant contributions to liquid crystal technology. With a total of 7 patents, Miura has made remarkable advancements in optical devices that enhance printing capabilities.
Latest Patents
One of Miura's latest inventions is a dual frequency, optically active liquid crystal cell. This high-speed responsive liquid crystal optical device boasts improved light transmissivity. The device features a liquid crystal panel that includes an optically active liquid crystal material with dielectric anisotropy, which becomes zero at a crossing frequency ('fc') of 100 KHz or below. The dielectric anisotropy is positive at frequencies lower than fc ('fl') and negative at frequencies higher than fc ('fh'). The device is equipped with crossed polarizers on each side of the liquid crystal panel. A liquid crystal driving circuit selectively applies a signal of frequency fh to open the device and a signal of frequency fl to close it. This optical device is particularly well-suited for use as a light valve in printer devices. Its response time of less than 1 millisecond allows for a printing speed of 10 A4 size prints per minute, achieving a resolving power of about 10 dots per millimeter. This translates to a printing speed of approximately 500 lines per second, with each line being written in less than 1 millisecond. Additionally, Miura has developed a photosensitive printing apparatus designed for use with a photo-sensitive drum. This apparatus includes a spotlight source that generates a point source of light, a photo-optical converter that transforms the light into linear rays, and a series of microshutters that selectively transmit light to the photo-sensitive drum.
