Yoshito Tsuyama is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of manufacturing, particularly in the production of metal pipes. With a total of 3 patents to his name, Tsuyama's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method for manufacturing spiral-welded steel pipes. In this process, a material strip or plate is fed in its longitudinal direction and continuously formed into a spiral pipe form. The side edges of the strip are welded together using the electric-resistance method where they meet. The edges are held together simultaneously with or immediately after the welding using a pair of pressure rolls. The bead formed from the welding is reformed during this process. Additionally, the electric-resistance welded side-ends are welded again by the arc method. Another significant patent is a method of manufacturing a metal pipe with longitudinally differentiated wall thickness. This involves preparing a rectangular metal plate with thinner and thicker portions, adjusting the width, and then bending the plate to form a tubular piece. By butt-welding the adjoining edges, a metal pipe with differentiated wall thickness is achieved.
