Title: Innovations by Masahiro Doe in Tire Vulcanization

Introduction

Masahiro Doe is a notable inventor based in Takasago, Japan, recognized for his contributions to the field of tire vulcanization. With a total of two patents to his name, Doe has developed innovative methods that enhance the efficiency and productivity of tire manufacturing processes.

Latest Patents

His latest patents include a tire vulcanizing method and a tire vulcanizer. The tire vulcanizing method focuses on reducing energy consumption while increasing productivity during the vulcanization process. This method involves supplying an inert gas to the internal space of the tire through a supply pipe, discharging the gas via a return pipe, and utilizing a rotation type circulation device to recycle the gas. A heating device is employed to heat the circulated gas, while an internal outlet gas temperature sensor monitors the temperature in the return pipe. The controller adjusts the rotation speed of the circulation device based on the detected gas temperature.

The tire vulcanizer patent describes a system with two sets of portions, each containing a lower mold, an upper mold, and a center mechanism equipped with a bladder. Nitrogen gas, heated in a first heating device, is supplied to the bladder's interior, facilitating vulcanization and patterning. The discharged nitrogen gas is then reheated in a second heating device before being supplied to the downstream bladder, ensuring optimal temperature management throughout the process.
