Title: **The Innovative Contributions of Shunji Misawa**

Introduction

Shunji Misawa is a notable inventor based in Tsuchiura, Japan. With a remarkable portfolio of innovations, he holds two patents that reflect his significant contributions to technology, particularly in the fields of surface treatment methods and plasma display panel technology.

Latest Patents

Among his latest patents, Misawa has developed two groundbreaking methods: a surface treatment method for aluminum alloy and a surface treatment method for magnesium alloy. These inventions aim to enhance the corrosion resistance of alloys while preventing the scattering of magnesium in high-temperature vacuum conditions. Specifically, by applying a carbon fluoride compound on the surface of the aluminum or magnesium alloy and subsequently heating it in an oxygen atmosphere, a fluoride passivation film is formed. This innovative approach offers a vital solution for the longevity and reliability of these materials in challenging environments.

In addition to surface treatments, Misawa has also pioneered a protective film for plasma display panels. This protective film, primarily composed of Calcium Oxide (CaO) and Strontium Oxide (SrO), reduces the work function compared to conventional Magnesium Oxide (MgO) films. As a result, the plasma display panel operates at a lower discharge voltage, prolonging its service life and enhancing brightness due to the inclusion of xenon gas in the plasma-gas mixture.
