Title: Innovations of Shunji Takenaka
Introduction
Shunji Takenaka is a notable inventor based in Hatano, Japan. He has made significant contributions to the field of optical materials and manufacturing processes. With a total of 2 patents, his work focuses on advanced methods for creating laminated transparent substrates and optical compensators.
Latest Patents
One of his latest patents is a method of manufacturing a laminated transparent substrate. This innovative process involves sandwiching ionomer resin between transparent glass substrates, which is formed by bridging ethylene-methacrylic acid copolymers with sodium ions. The method includes sealing the laminated structure in a reduced pressure atmosphere, applying heat and pressure, and then rapidly decreasing both the pressure and temperature of the structure.
Another significant patent is for an optical birefringence compensator. This method entails providing a sheet of ionomer bridged with sodium or magnesium ions and stretching it to generate uni-axial optical anisotropy. The stretched sheet is then sandwiched between substrates, placed in an evacuatable heat-resisting bag, and treated in an autoclave furnace under heat and pressure. The resulting sheet exhibits a positive optical anisotropy along the stretched direction and a negative optical anisotropy perpendicular to the sheet after treatment.
