Title: **Ken Fujiwara: Innovator in Tire Technology**

Introduction

Ken Fujiwara, an accomplished inventor based in Urawa, Japan, has made significant contributions to the field of tire technology with a total of four patents to his name. His inventive spirit has led to the development of innovative solutions designed to enhance vehicle safety and performance.

Latest Patents

Among his recent patents, two noteworthy inventions stand out. The first is a patented sealant aimed at preventing blowouts in tubeless tires and tire tubes. This inventive sealant features a carefully calibrated viscosity range of 25 to 35 dPa·s and a thixotropy index between 6.5 and 11.0. When a vehicle is in motion, the viscosity of the sealant decreases due to stirring actions induced by vibrations or centrifugal forces, allowing it to disperse evenly within the sealant chamber. Upon stopping, the viscosity increases, preventing the sealant from flowing downward due to gravitational forces. This mechanism effectively minimizes vibrations and noise during high-speed travel.

The second notable patent is for a method of producing a reclaimed joint sheet, which serves as a gasket or packing member for applications in automobiles and ships. This joint sheet is constructed in layers, incorporating a first layer from a specific composition, a second layer produced from finely pulverized pieces of the original joint sheet, and a third layer identical to the first. This innovative design enhances the durability and functionality of automotive and marine joints.
