Latest Patents

One of his latest patents is focused on a shadow mask support member that boasts high strength and thermal deformation resistance. This innovative support member is designed to hold a shadow mask of a Braun tube and is made from a parallel bonded-type bimetal. The design incorporates a high-strength, low-expansion alloy plate bonded to a high-expansion alloy plate, ensuring excellent thermal resistance and mechanical strength. The low-expansion alloy plate consists of specific weight percentages of carbon, silicon, manganese, nickel, molybdenum, and iron, providing an average thermal expansion coefficient of not more than 6 × 10⁻⁶ /°C at 30-100°C.

Another notable patent involves a shadow mask sheet made from an Fe-Ni invar alloy. This sheet exhibits excellent etchability and is produced through a series of hot-rolling and cold-rolling processes, resulting in a fibrous microstructure. The alloy consists of 30-40 weight % of nickel, with the balance being primarily iron and inevitable impurities. The production method ensures a high percentage of {100} texture in the rolled surface, enhancing its performance in applications.
