Latest Patents

Ikuo Nakazato's latest patents showcase his ingenuity in developing advanced propeller technologies. One notable invention is the **Variable Propeller for Boat**, which features variable-diameter main blades alongside stationary subsidiary blades mounted on a propeller boss. This design enhances low-speed driving properties, as well as high-speed and high-output performance. When in closed positions, the main and subsidiary blades align axially, minimizing the propeller's diameter. In contrast, when the main blades open, the surfaces of both blades align for optimized performance.

Another significant patent is the **Propeller for Boat**, where a mix of stationary and variable blades is arranged around the outer periphery of a propeller boss. This innovative design includes exhaust passages that allow for efficient passage through the boss at points corresponding to the stationary blades. This configuration permits the formation of a larger section area in the blade boss without obstruction by the shaft of the variable blade, ensuring effective functionality.
