Latest Patents
One of Shimizu's latest patents is a wear-resistant reed for a high-speed loom. This invention features a diamond-like carbon (DLC) film formed on a portion of a reed blade, which is essential for high wear resistance. The design incorporates stainless steel as the base material, with a titanium carbide layer serving as an intermediate layer. The reed blades are strategically coated with a DLC film at the side portions where wear occurs rapidly, while the central portion utilizes either hard films or non-coated blades to ensure uniform wear across the entire reed. This innovation is compatible with various types of fibers, including natural, synthetic, and new material fibers.
Another significant patent is for a permanent magnetic alloy comprising gold, platinum, and cobalt. This alloy is primarily composed of gold, making it suitable for creating magnetic personal ornaments. The composition includes 50 to 75 weight % gold, 12 to 40 weight % palladium, and 3 to 15 weight % cobalt. The resulting alloy is available in gold or white gold colors and can be plastically deformed into desired shapes. The 12, 14, and 18 Karat gold alloys exhibit maximum energy products of 3.0, 2.2, and 0.9 MGOe, respectively.
