Introduction

Katsumi Iijima is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the field of thermoplastic resin technologies. With a total of 2 patents, Iijima's work focuses on innovative methods that enhance the capabilities of thermoplastic materials.

Latest Patents

Iijima's latest patents include an "Even pressure welding method by using fluid pressure." This method involves vacuum-packing joined members made of thermoplastic resin, which have a fluid flow path formed of a groove and/or a hole in a junction face. The wrapped body is heated to soften the joined members, allowing them to be welded together through the application of fluid pressure. This process ensures even pressurization from the periphery, followed by cooling to solidify the weld. Another significant patent is the "Method for embedding part in base made of thermoplastic resin." In this method, an embedding hole is formed in a thermoplastic resin base, and an embedded part is inserted. The base undergoes heating treatment to soften it, followed by restraining treatment to control outward thermal expansion, allowing the base to conform closely to the embedded part.
