Introduction

Yasushige Otani is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of rust-resistant technology, particularly in water pipeline applications. With a total of 2 patents to his name, Otani's work focuses on enhancing the durability and reliability of water infrastructure.

Latest Patents

Otani's latest patents include a rust-resistant sleeve designed for use in a branch hole of a water pipeline. This innovative sleeve unit features a water-absorbing swelling rubber that ensures a reliable seal while controlling rust development. The design incorporates a cylindrical metal sleeve with a flange on its outer circumference, leaving a specific height length of the metal sleeve uncovered. This allows for effective insertion into the inner circumference of the branch pipe connected to the branch hole.

Another patent by Otani is a rust-resistant cylindrical metal sleeve that prevents rust and corrosion around the wall of a branch hole. This sleeve is designed to be rigidly fitted into a drilled branch hole of a metal conduit, such as a water pipeline. It features a projecting portion on its outer circumference and an inner flange portion that projects inward at its lower end. The outer circumference of the sleeve is coated with a water-absorbing swelling rubber, which is blended with synthetic resin rubber and a water-absorbing polymer. This unique composition allows the rubber to increase in volume as it absorbs water, thereby preventing water ingress between the metal sleeve and the wall of the branch hole.
