Title: Hiroshi Machida: Innovator in Optical Fiber Technology
Introduction
Hiroshi Machida is a prominent inventor based in Annaka, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 4 patents. His innovative methods and apparatuses have advanced the manufacturing processes of glass base materials used in optical fibers.
Latest Patents
Hiroshi Machida's latest patents include a method of manufacturing porous glass base material used for optical fibers. This method involves flame-hydrolyzing raw materials for glass in an oxyhydrogen flame. The generated glass fine particles are deposited on a rotating target to form porous glass base material. The process includes dehydrating and sintering the porous glass base material to transform it into clear glass. A key feature of this method is the adjustment of the temperature difference between the surface temperature of the porous glass base material touching the burner flame and the surface temperature before touching the flame, ensuring it remains within the range of 200 to 700 degrees centigrade.
Another notable patent is the glass base material manufacturing apparatus and method. This apparatus is designed for manufacturing a glass base material, which serves as a base material for optical fibers. It comprises a base rod around which the glass base material is formed, a burner that hydrolyzes and accumulates gas material around the base rod, and two burner-moving units that facilitate the movement of the burner in relation to the base rod.
