Latest Patents

One of Okamura's latest inventions is a photosensitive printing apparatus. This innovative printing apparatus is designed for use in printers equipped with a photo-sensitive drum. It features a spotlight source that generates light, providing an essentially point source. The apparatus includes a photo-optical converter that converts the light from the spotlight source into linear rays of light. Additionally, a plurality of microshutters, which are optically coupled to the photo-optical converter, selectively transmits light to the photo-sensitive drum. This design creates a defined light path from the spotlight source through the photo-optical converter and the microshutters to the drum.

Another significant invention by Okamura is a liquid crystal shutter. This device incorporates means for stabilizing the molecular orientation of a liquid crystal material. In one embodiment, isolation electrodes are positioned parallel to and between adjacent common electrodes on a substrate. In an alternate embodiment, the effective gap distance between adjacent common electrodes is at least ten times greater than the distance between opposing substrates.
