Title: The Innovations of Tomoyuki Hashimoto

Introduction

Tomoyuki Hashimoto is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of fuel injection technology, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of Hashimoto's latest patents is a fuel injection device designed to reduce the amount of fuel discharging to the outside. This device features a nozzle body, an injection control valve, and a close assistance piston. The nozzle body contains a first fuel chamber and a nozzle valve close chamber. The injection control valve can advance to a first position, allowing communication between the first fuel passage and the first fuel chamber while blocking access to the third fuel passage. When the valve retreats to a second position, it blocks access from the first passage to the first chamber and allows communication with the third passage. The close assistance piston plays a crucial role in preventing fuel from discharging outside the device.

Another significant patent by Hashimoto is a diffusion joining structure. This innovation involves the external surface configuration of a mounted member that is joined to a mounting member. At the distal end position, which first contacts the mounting member, there is a curved surface bulged toward the mounting member. Other curved surfaces are also bulged toward the mounting member, with larger radii of curvature linking up with the initial curved surface.
