With a total of three patents to his name, he has made significant advancements in the field, particularly in the development of reinforced optical fibers and innovative molding methods.

Latest Patents

One of Yoji Ida's latest patents is for a reinforced optical fiber. This invention features a single-core cord that includes an optical fiber element, which is covered by a primary coating made of silicone rubber. The secondary coating has a unique three-layer structure, consisting of a reinforcing inner layer made of longitudinally arranged reinforcing fibers and a cured non-styrene binder. This binder contains an unsaturated polyester resin with a non-styrene monomer as a cross-linking agent. Additionally, the outer layer is formed of fiber-reinforced cured styrene resin, while the surface layer is made of thermoplastic resin, ensuring a strong bond between the layers.

Another notable patent is a method for continuous molding of a rod-like product. This method involves creating an uncured rod-like molding by passing reinforcing fibers impregnated with uncured thermosetting resin through a specially designed squeezing die. The process includes extruding molten thermoplastic fluororesin in a ring shape to enclose the rod-like molding. The resulting sheathing layer is formed by cooling and solidifying the thermoplastic resin, which is then hardened in a heated tank, ultimately producing a rod-like product with a surface of fiber-reinforced thermosetting resin.
