Title: Toshiaki Makino: Innovator in Railway Car Design

Introduction

Toshiaki Makino is a prominent inventor based in Kudamatsu, Japan. He has made significant contributions to the field of railway car design, holding a total of 15 patents. His innovative approaches have led to advancements in safety and efficiency in railway transportation.

Latest Patents

One of Makino's latest patents involves a railway car design that features a front end portion disposed on the front end of the car body. The floor consists of extruded hollow members that act as shock absorbers. These shock absorbers are divided into upper and lower sections, utilizing annealed extruded hollow members to form the structure. The hollow members are strategically placed to align with the longitudinal direction of the car body. They are divided longitudinally by a plate, allowing for even deformation upon impact. This design enables the members to fold into concertinas, effectively absorbing impact forces. Another patent focuses on the underframe of a railway car, composed of multiple hollow shape members. These members are arranged to ensure their longitudinal orientation matches that of the car body. The underframe is constructed by welding these members together using friction stir welding, which maintains structural integrity during impact.
