With a total of 11 patents to his name, Kuragaki's work has had a lasting impact on the industry.
Latest Patents
Kuragaki's latest patents include innovative designs aimed at enhancing the performance and safety of marine outboard drives. One of his notable inventions is an outside power source-type electrical corrosion protection system. This system features several embodiments of reference electrode constructions that are used in electrically anti-corrosion protection systems for marine outboard drives. Each embodiment contains a reference electrode within a protective covering that has a restricted small volume area. This design ensures that when the reference electrode dissolves in the surrounding water, it forms a saturated solution in the small volume area, preventing further dissolution.
Another significant patent is the hydraulic tilt and trim unit for marine drives. This invention introduces an improved flow control mechanism for tilt and trim adjustment systems, which accelerates the tilt operation of associated outboard drives without compromising control during trimming. The mechanism includes a bypass line that connects both sides of a tilt and trim cylinder, with a bypass valve that regulates the flow. This allows for quick adjustments within the tilt range while maintaining a slower speed for precise control in the trim range.
