Introduction

Tadahiko Ooba is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of engineering, particularly in the development of systems that enhance the performance and longevity of structures exposed to harsh environments.

Latest Patents

Ooba holds a patent for an antifouling system designed for structures exposed to seawater and heat exchangers. This innovative system utilizes a titanium sheet that serves as an anode-forming member, which is fixed on a tube plate of a heat exchanger via an insulating sheet and an insulating adhesive. The titanium sheet is coated with a film of an electrochemically active, stable electrical catalyst. A direct current (dc) power unit is connected to the sheet, with a positive electrode linked to it and a negative electrode connected to the tubes. The inner surfaces of the tubes act as a cathode for electrolysis, generating oxygen while suppressing chlorine generation in seawater. An automatic potential controller adjusts the potential difference between the electrodes, ensuring optimal performance. Additionally, an external dc power unit and a cathodic protection electrode supply a cathodic protection current to the tubes.
