Introduction

Tomohiro Sakai is a notable inventor based in Obu, Japan. He has made significant contributions to the field of laser technology, particularly in the area of welding methods. His innovative approach has led to the development of a unique patent that enhances the efficiency of welding processes.

Latest Patents

Sakai holds a patent for a laser welding method. This method involves welding a filter made of a laser beam-transmittable fiber material to a case made of a laser beam-nontransmittable resin material. The process begins with placing the filter on the case, followed by pressurizing the filter with a jig to increase the fiber density at the welding portion. The welding portion is then irradiated by a laser beam. During the fiber density increase, the jig pressurizes the periphery of the welding portion, enhancing the fiber density over a larger area. As a result, the laser beam melts part of the case, allowing the melted resin to permeate through the gaps between the fibers, effectively welding the two components together.
