Title: Yasunobu Nakagoshi: Innovator in Optical Technologies
Introduction
Yasunobu Nakagoshi is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of optical technologies, holding a total of 4 patents. His work focuses on advancements in polarized materials and manufacturing methods for optical lenses.
Latest Patents
One of his latest patents is a molded laminate for optical use. This invention involves a polarizing sheet that includes a polarizing film and cellulose triacetate films bonded to opposing surfaces of the polarizing film with adhesive layers interposed. A thermoplastic film is stacked on the exposed surface of one of the cellulose triacetate films. Another cellulose triacetate film, free of an ultraviolet absorber, is bonded to the exposed surface of the other cellulose triacetate film of the polarizing sheet with an adhesive containing an organic photochromic compound, forming a laminate sheet. This laminate sheet is then placed in an injection mold, where a molding resin material fusible with the thermoplastic film is injected over it.
Another significant patent is a method of manufacturing polarized spectacle lenses. In this process, a film of a plastic material that is fusible with a lens-forming material and has high light transmissivity is bonded and laminated to a polarizing sheet with a polarization coefficient of 99.0% or higher. The resultant laminate is hot-pressed into a shape similar to an aimed lens, and a lens-forming resin is injected into the cavity to form a polarized lens.
