Latest Patents

One of Toshio Tsukada's key patents is for a grain-oriented electrical steel sheet that possesses stable magnetic properties. This invention proposes a steel sheet that has a low watt loss after stress relief annealing. The final texture of the steel sheet is achieved through annealing, and it features recessed parts on its surface that form indentations with a depth ranging from 0.01 to 0.1 mm. These recessed parts are filled with a composition that has a coefficient of thermal expansion smaller than that of the steel sheet body. This design allows for the subdivision of magnetic domains, enhancing the overall performance of the material.
