Title: Sadao Ishihara: Innovator in Structural Member Production
Introduction
Sadao Ishihara is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of structural engineering through his innovative patent. His work focuses on enhancing production methods and reducing costs while maintaining dimensional accuracy.
Latest Patents
Ishihara holds a patent for a "Structural member having closed sections, and apparatus and method for producing the structural member." This invention aims to decrease production costs and secure dimensional accuracy through a simple construction. The apparatus he developed produces a structural member with a channel-shaped sectional portion and adjacent closed sectional portions by bending a workpiece. It includes a press mold formed of a punch and a die, which are used for press-forming. This design ensures that both side edges of the workpiece overlap on the bottom wall of the channel-shaped sectional portion. Additionally, a fall-down prevention means is incorporated to guide the side edges, ensuring they come into contact with each other during the press-forming process. The die applies a compression force, resulting in a curved portion with residual compression stress between the longitudinal outer side wall and the vertical outer side wall.
