Title: **Yasuo Imamura: Innovator in Steel Strip Production Technology**
Introduction
Yasuo Imamura, an inventive mind based in Urawa, Japan, has made significant contributions to the field of steel production with his innovative patents. With a total of three patents to his name, Imamura has focused his efforts on advancing technologies that enhance the manufacturing processes of steel products.
Latest Patents
Among his noteworthy patents, Imamura developed a unique process for producing steel strip material specifically for manufacturing applications such as the shadow mask of Braun tubes used in color televisions. His process involves cold rolling low carbon steel strip with a reduction of 15 to 35% during the final cold rolling step. The steel is subsequently annealed in the form of tight coils at temperatures ranging from 520 to 600 degrees Celsius, resulting in products with grain sizes between numbers 4 to 7 and coercive forces of not greater than 2.0 Oersted. This innovative approach ensures that the steel strip possesses the necessary properties for effective usage in color TV shadow masks. Additionally, Imamura’s patent outlines the specific composition of a steel alloy for the shadow mask, emphasizing its suitability for subsequent processing steps due to a Vickers hardness of at least 110.
