Title: Hisatoshi Tsuchida: Innovator in Hose Production Technology

Introduction

Hisatoshi Tsuchida is a notable inventor based in Ootawara, Japan. He has made significant contributions to the field of hose production technology, particularly in developing methods that enhance the durability and reliability of hoses used for transferring refrigerant gases.

Latest Patents

His most recent patent is titled "Method for producing hose having low permeability." This innovative method involves preparing a rubber mandrel with an outer releasing layer made of fluoride rubber. The process includes applying a silicon-based releasing agent with a viscosity of 300-1000 cs to the mandrel while it is in motion. Subsequently, a molten resin is extruded and coated onto the mandrel, forming a resin layer. This technique improves the releasability of the mandrel, preventing damage to the resin layer when the mandrel is removed. The resulting hose is particularly effective for transferring refrigerant gases, such as freon, as it minimizes gas leakage and enhances durability.
