Latest Patents

Among his latest inventions, Toyoda developed significant methodologies aimed at enhancing the production processes of aluminum materials. One notable patent is a method of producing aluminum material for use as electronic material. This innovative technique involves melting aluminum that inherently contains uranium (U) and thorium (Th) to create molten aluminum. The process requires holding the molten aluminum at elevated temperatures and employing a hollow rotary cooling member that rotates in the molten aluminum. This system ensures the cooling member’s surface is maintained at a temperature lower than the solidification point, facilitating the crystallization of aluminum with reduced levels of U and Th.

Another remarkable patent outlines a method for preparing high-purity metal. This invention describes the immersion of a hollow rotary cooling member in molten metal that contains eutectic impurities. By rotating the cooling member while simultaneously supplying a cooling fluid, high-purity metal can crystallize on the metal deposition area of the cooling member. The process effectively generates a downward flow of molten metal, ensuring that impurities are minimal in the resulting high-purity material.
