Title: Koichi Warino: Innovator in Multi-layer Structures and Molding Technologies
Introduction
Koichi Warino is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the field of materials science, particularly in the development of multi-layer structures and molds for resin molded articles. With a total of 4 patents to his name, Warino's work showcases his expertise and innovative spirit.
Latest Patents
One of Warino's latest patents is focused on a multi-layer structure that excels in barrier properties against alcohol gasoline, especially hydrocarbon components. This innovative structure also demonstrates excellent interlayer adhesion, low-temperature impact resistance, heat resistance, and chemical resistance. The multi-layer structure comprises two or more layers, including at least a layer (a) made of nylon 11 and/or nylon 12, and a layer (b) consisting of a polyamide resin (nylon 9T). This polyamide resin is composed of a dicarboxylic acid component and a diamine component, with specific percentages of terephthalic acid and diamines such as 1,9-nonanediamine and 2-methyl-1,8-octanediamine. Additionally, the structure may include a layer (c) of nylon 11, nylon 12, or nylon 6.
Another significant patent involves a mold for producing resin molded articles. This mold features a molding cavity with a member that has a recessed surface defining the shape of the article being molded. A thin plate body with a specific heat capacity is positioned between the molding cavity wall and the member. This design allows the resin, when introduced at a high temperature, to cool near the recessed surface before being heated again to exceed its transfer starting temperature after filling the recessed surface.
