With a total of 4 patents to his name, his work showcases innovative approaches to manufacturing and material properties.

Latest Patents

One of Tomikawa's latest patents is a screen-formed plated article comprising mesh cloth using core-sheath composite filament. This invention features a mesh cloth that prevents clogging and maintains uniform openings across its surface. It serves as a stable printing screen and is useful as an electromagnetic wave shielding material and a shadow mask. The production process involves using a core-sheath composite filament, where the sheath has a lower melting point than the core. A metal plating is applied to the mesh cloth, ensuring that the core threads at the intersections are adhered by melting the sheath component, resulting in a uniform surface coverage.

Another significant patent is a method of manufacturing a damper for a loudspeaker. This damper is created by molding a substrate into a desired shape using a fabric or knitted cloth made from core-sheath type conjugate fibers. The resin forming the core material acts as a matrix, while the sheath material, which has a lower melting point, is fused during heat treatment. This process simplifies substrate production and results in a loudspeaker damper with excellent moldability, waterproofness, and durability.
