Title: Narutoshi Murasugi: Innovator in Microcomponent Manufacturing

Introduction

Narutoshi Murasugi is a prolific inventor based in Matsudo, Japan, with a remarkable portfolio consisting of four patents. Murasugi is known for his innovative contributions to the field of microcomponent manufacturing, focusing on developing advanced forming die assemblies that enhance production efficiency and quality.

Latest Patents

Murasugi's latest patents are a testament to his ingenuity and engineering expertise. His first patent describes a forming die assembly for microcomponents, which includes a forming die and a punch. This assembly is designed with a cavity and a punch hole connected to a supply path for a raw material consisting of metal powder and a binder with plasticity. The punch can slide into the punch hole, effectively opening and closing a gate to allow raw material to fill the cavity. By doing so, the punch compresses the material into a green compact, demonstrating Murasugi's focus on precision and efficiency in manufacturing microcomponents.

The second patent also concerns a forming die assembly for microcomponents, featuring a design that includes a forming die, a plunger, and a punch. In this configuration, the plunger slidably fills the cavity with stored raw material from the storage portion through the punch hole. Like the first patent, the punch's reciprocatory sliding action is pivotal in compressing the raw material into a compact form, showcasing Murasugi's continuous commitment to innovating production methods.
