Title: The Innovative Mind of Nobuyuki Matsui

Introduction

Nobuyuki Matsui, an accomplished inventor based in Kaga, Japan, has made significant contributions to the field of mechanical engineering, particularly through his groundbreaking patents. With a total of 3 patents to his name, his work focuses on advanced silent chain technology, which enhances both productivity and wear resistance in industrial applications.

Latest Patents

One of Matsui's notable inventions is the design of a double-sided driving silent chain and a double-sided driving silent chain transmission. This innovative silent chain features double-sided driving link plates, which are designed with symmetrical upper and lower teeth. A primary challenge with traditional designs is that they often fail to maintain the necessary risky sectional area of the plates due to narrow width between the upper and lower crotches. Matsui's solution includes undercutting the back side of the link plates and creating unsymmetrical upper and lower parts, ensuring the required sectional area is met. Furthermore, the teeth on the back side are cut away to create a flat surface, enhancing contact area with shoes and other components.

Another significant patent involves a link chain where a bush is pressed into a turning link rank. This bush is uniquely molded into a seamless cylindrical shape through cold-forging and is coated with a high-strength metal carbide layer, substantially improving wear resistance. Additionally, through processes such as quenching and tempering, Matsui's invention not only enhances productivity but also reduces associated costs in manufacturing.
