Title: The Innovations of Sumiyo Wakaki

Introduction

Sumiyo Wakaki is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of materials science, particularly in the development of glass ceramic substrates. His innovative work has led to the filing of a patent that showcases his expertise and creativity.

Latest Patents

Wakaki holds a patent for a "Glass ceramic substrate and method for producing the same." This invention involves a unique process where a first paste film containing a metal powder and non-vitreous inorganic oxide is formed on a glass ceramic green sheet. A second paste film, which also contains a metal powder, is then applied to cover at least the edge portion of the first paste film. The glass ceramic green sheet, along with the two paste films, is subsequently fired to produce a surface electrode. This electrode is then plated, resulting in a structure where the second paste film contains less non-vitreous inorganic oxide than the first. Notably, the abundance ratio of the non-vitreous inorganic oxide in the surface electrode is lower in the region bordering the plating layer compared to the region bordering the glass ceramic layer, particularly at the edge portion of the surface electrode.
