Latest Patents

Hidetoshi Usui holds a patent for a marine organism prevention system for structures in seawater. This antifouling system features an anode forming member that is bonded to the seawater-exposed surface of the structure using an insulating adhesive. The anode forming member is coated with an electrical catalyst film that is both electrochemically active and stable. A conductive member is also included, which is designed to be wetted with seawater. The system is powered by an external DC power supply, which is equipped with an automatic potential controller. This controller regulates the potential difference between the positive and negative terminals, allowing for the generation of oxygen in seawater while suppressing chlorine generation. This innovative design helps prevent abnormal corrosion of metal parts, even if the rubber lining that protects them is damaged.
