Title: Tomoyuki Torii: Innovator in Printing Technology

Introduction

Tomoyuki Torii is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of printing technology, holding a total of 3 patents. His innovative work focuses on systems that enhance the quality and efficiency of color printing.

Latest Patents

One of his latest patents is a capsule rupture printing system designed for use in printing systems. This apparatus allows for the controlled rupture of a capsule layer to release dye, which prints an image on an image-receiving sheet. An optical valve member is strategically positioned between a light source and an imaging sheet that has a layer of capsules on its surface. The image pattern is formed on a ferroelectric ceramic plate of the optical valve member through the irradiation of an electron beam and ultraviolet light, in accordance with each color separation signal. The imaging sheet is then positioned so that the layer of capsules lies between it and the image-receiving sheet. A pressure roller applies pressure to rupture the capsules, thereby transferring the dye to the image-receiving sheet.

Another notable patent by Torii is also a capsule rupture printing system, which is utilized in color printing systems. In this system, an image is projected using a series of monochrome pictures corresponding to three primary colors onto an imaging sheet containing layers of pressure-rupturable capsules. Each capsule encapsulates a dye and a photosensitive composition. The monochrome pictures are created by a laser scanner unit on a photosensitive drum and are subsequently transferred to a transparent film. This film is then moved between a light source unit and a projection lens unit to project the images onto the imaging sheet.
