Title: The Innovations of Shin Toyokawa

Introduction

Shin Toyokawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of engineering, particularly in the areas of press forming methods and analyzing apparatuses. With a total of three patents to his name, Toyokawa's work reflects a commitment to advancing technology and improving manufacturing processes.

Latest Patents

One of Toyokawa's latest patents is a press forming method for vehicle components. This method involves press forming a workpiece between a die and a punch, utilizing a relative motion to push the punch into the die. The process includes producing an intermediate molding with ridges formed in predetermined parts of the workpiece, which are then press formed into a final shape. This technique effectively thickens and work-hardens specific areas of the workpiece, enhancing its durability.

Another significant patent is an analyzing apparatus, method, and computer program. This invention generates first displacement distribution data that indicates how a member deforms due to springback, based on finite element model data, material physical property data, and stress distribution data. It also produces second displacement distribution data that reflects the displacement of the member across various natural vibration deformation modes. By analyzing the degree of coincidence between these data sets, the apparatus selects natural vibration modes to determine a modified shape that increases natural vibrations, bringing the member closer to a target shape.
