Title: Shumpei Miyajima: Innovator in Ceramic-Coated Metal Sheets
Introduction
Shumpei Miyajima is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of materials science, particularly in the development of ceramic-coated metal sheets. With a total of 3 patents to his name, Miyajima's work showcases innovative approaches to enhancing the decorative properties and weatherability of metal substrates.
Latest Patents
Miyajima's latest patents include a ceramic single layer-coated metal sheet and a ceramic multiple layer-coated metal sheet. The single layer-coated metal sheet features a transparent ceramic layer formed on a metal substrate through dry processes such as physical vapor deposition or chemical vapor deposition. This layer has a thickness ranging from 0.05 to 5 micrometers and a refractive index of at least 2.0 in the visible region. The multiple layer-coated metal sheet further includes a colored ceramic layer, which is positioned between the substrate and the transparent ceramic layer. This colored layer is composed of nitrides, carbides, and carbonitrides of elements like titanium, zirconium, hafnium, chromium, niobium, and aluminum, with a thickness of 0.1 to 1 micrometer.
Another significant patent involves a process for manufacturing a multi ceramic layer-coated metal plate. This process results in a metal plate that exhibits an excellent decorative color through a multi-ceramic coating. The colored ceramic layer is formed over the metal plate and is made from nitrides and carbides of various elements, while the transparent ceramic layer is created from silicon oxide, silicon nitride, or aluminum oxide. The thickness of these layers varies, and the deposition can be performed in different orders.
