Latest Patents

Hiroshi Sugihara holds a patent for a "Method of preparing composite sintered body." This invention relates to a method that involves preparing a composite sintered body with inner and outer portions that fit together. The process includes several steps: preparing an inner powder compact, preparing an outer powder compact, fitting these compacts together to create a composite powder compact, and finally sintering this compact to form the composite sintered body. The method ensures that the inner powder compact grows more than the outer compact during sintering, resulting in a strong bond between the two portions. The materials used for the compacts include wax-type and metal-soap-type segregation prevention powder mixtures, enhancing the mechanical properties of the final product.
