Latest Patents

Kazuo Hayakawa holds a patent for a "Method and apparatus for correcting the hardening deformation of annular elements made out of steel." This patent describes a method where, during the cooling stage of hardening, an annular element with an austenitic structure is subjected to working on either the outside or inside diameter. The degree of working varies, being 0.05-1.0% for the outside diameter and 0.5-3.0% for the inside diameter. This process effectively corrects deformation in annular steel elements caused by heat treatments, resulting in completely round, strain-free, or deformation-free products.
