Title: Innovations of Kunio Shibatsuji
Introduction
Kunio Shibatsuji is a notable inventor based in Kusatsu, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced laminates. With a total of 3 patents to his name, his work has had a considerable impact on various applications.
Latest Patents
One of his latest patents is a metal-film laminate that includes a metal plate and a biaxially oriented polyester-group film laminated on the metal plate. The orientation degree of the film is controlled such that, when the thickness of the film is represented by T and the mean orientation degree of the film in the area from the metal-plate side surface to a position of T/2 in the thickness direction of the film is represented by X, the orientation degree of the film in the area from the metal-plate side surface to the position of T/2 is in the range of X ± 0.5X, and an orientation degree of the film at the non-metal-plate side surface is not less than 2X. This innovation allows for excellent drawing properties and impact resistance in the resulting metal-film laminated products. Another significant patent is for a polyester film designed for use in laminates with metal plates. This polyester film comprises a polyester-group resin containing a white pigment with a mean particle diameter of 0.01 to 1.8 µm at a content of 10 to 30% by weight. The film exhibits a void ratio of 4 to 30%, a melting peak temperature of 150°C to 245°C, an oligomer content of not more than 3% by weight, and an orientation degree of 0.7 to 4.0. When laminated on metal, this film demonstrates excellent light interruptive properties, lamination properties, forming properties, and processing properties.
