Latest Patents
One of Okoshi's latest patents is a process for producing a metal-polyimide composite article. This invention addresses the challenge of preventing the deterioration of polyamide film due to oxidation during the imidization of a polyimide precursor in contact with metals such as copper or silver. The process is characterized by the use of a polyimide precursor that has a masked acidic functional group, which enhances the durability of the resulting composite material. Examples of suitable polyamide precursors include polyamic acid epoxy adducts, amido polyamic acids, and silylated polyamic acids.
Another significant patent is related to a nuclear fusion reactor. This invention introduces a new vacuum vessel designed to enclose plasma particles. The reactor wall, which is exposed to these plasma particles, features a piled structure. A series of heat-resisting ceramic tiles are metallurgically bonded to a metal-base body equipped with a cooling mechanism through a brazing material. The ceramic tiles are preferably made of high-density sintered silicon carbide, with a small amount of beryllium oxide present between the boundaries of the crystal grains.
