Title: The Innovative Contributions of Makoto Matsui
Introduction
Makoto Matsui is a prominent inventor based in Kunitachi, Japan, known for his significant contributions to various technological fields. With a total of 11 patents to his name, Matsui has made remarkable advancements, particularly in the areas of materials processing and display technology.
Latest Patents
One of Matsui's latest patents is a method for reducing alumina or magnesia by utilizing supersonic gas flow. This innovative process not only avoids the emission of harmful greenhouse gases but also enhances energy efficiency compared to traditional methods like Hall-Heroult or Pidgeon. The process involves introducing alumina or magnesia powder with a carrier gas, pressure-transferring it to a throat in a reducing unit, and using a laser beam to convert the material into a plasma state. The thermally dissociated product is then jetted at supersonic speed to isolate aluminum or magnesium. Additionally, hydrogen can be added to accelerate the reduction process.
Another notable patent is for a liquid crystal display device and its driving method. This device features a first substrate with a thin film transistor and a light-screening film, which overlaps with an ITO layer. The second substrate, opposed to the first, includes a color filter and another light-screening film. This design improves the numerical aperture by extending the light-screening film based on external voltage.
