Title: Mamoru Arikawa: Innovator in Continuously Variable Transmission Technology

Introduction

Mamoru Arikawa is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of continuously variable transmission (CVT) technology. With a total of 3 patents to his name, Arikawa's work has been instrumental in enhancing the durability and efficiency of metal components used in CVTs.

Latest Patents

One of Arikawa's latest patents is focused on a belt for continuously variable transmission. This invention features protrusions formed on the inner peripheral surface of the innermost metal ring of the belt. These protrusions are designed to be initially worn, with an average contact width of less than 16 micrometers. This design inhibits the development of pitching at the top of the protrusion in a depthwise direction, effectively eliminating shallow pitching and preventing the generation of cracks. The invention also improves surface roughness, enhancing lubrication and ultimately increasing the durability of the metal ring.

Another significant patent by Arikawa is a method for measuring the free-state diameter of a metal ring. This method allows for the accurate determination of the free-state diameter in a continuously variable transmission by applying predetermined compression and tensile stresses to the outer and inner surfaces of the metal ring. The innovative approach ensures that the metal ring is cut at two points, allowing for precise measurement without interference.
