Latest Patents

Hiyama holds a patent for a resin-coated optical fiber. This invention includes a glass optical fiber composed of a core and a clad for coating the core. The optical fiber features a primary layer made of UV-curing resin in contact with the glass optical fiber. Additionally, there is a secondary layer made of the UV-curing resin disposed on the outer periphery of the primary layer. The primary layer has a two-layer structure, consisting of an inner layer in contact with the surface of the clad and an outer layer for coating the inner layer. The UV-curing resin of the inner layer has a Young's modulus of 0.9 MPa or more and 3.0 MPa or less at room temperature in a film state based on JIS standard K7113. The UV-curing resin of the outer layer has a Young's modulus of 0.1 MPa or more and 0.7 MPa or less at room temperature in a film state based on JIS standard K7113. Hiyama has 1 patent to his name.
