Latest Patents

Kobayashi holds a patent for "Molding compositions and diaphragms, arm pipes and head shells molded." This patent describes a molding composition created by blending flaky graphite with a resin component. The resin component consists of a mixture of thermoplastic resins, one with a glass transition temperature higher than room temperature and another with a lower glass transition temperature. The composition is kneaded and rolled into a sheet, orienting the graphite flakes parallel to the surface. The resulting sheet can be molded into various articles, such as speaker diaphragms, arm pipes, and head shells, which may be carbonized or graphitized. The final products exhibit enhanced physical properties, including a high specific modulus of elasticity comparable to aluminum and beryllium, along with good internal loss characteristics similar to paper.
