Introduction

Haruki Okuyama is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 3 patents. His innovative work has been instrumental in advancing the capabilities and applications of optical fibers.

Latest Patents

Okuyama's latest patents include a novel optical fiber design and a method for manufacturing optical fibers. The optical fiber comprises a glass fiber with a core and cladding, a primary resin layer in contact with the glass fiber, and a secondary resin layer covering the primary layer. The primary resin layer contains a cured product of a resin composition that includes a urethane (meth)acrylate oligomer, a monomer, a photopolymerization initiator, and an aromatic acid compound. The content of the aromatic acid compound is maintained between 20 ppm and 12000 ppm based on the total amount of the resin composition, with a Young's modulus of the primary resin layer being 0.6 MPa or less at 23° C.±2° C.

The method for manufacturing optical fiber involves a coating step where a first layer is formed by applying a first ultraviolet ray curable resin composition onto a glass fiber. This is followed by forming a second layer with a second ultraviolet ray curable resin composition. The process includes a first irradiation step to cure both layers and a second irradiation step to further enhance the optical fiber's properties.
