Latest Patents

Kusunoki's latest patents include a casting mold and method for manufacturing the same. This invention involves a casting mold molded by heating mulled sand, which consists of a mixture of refractory molding sand particles, an inorganic water-soluble binder, and water. The binder is a combination of a sulfate compound, such as magnesium sulfate heptahydrate, and a borate compound, like sodium tetraborate decahydrate. The casting mold is formed by baking the mulled sand in a way that retains water of crystallization in the sulfate compound while fusing and curing the borate compound.

Another significant patent is a surface treatment method, surface treatment apparatus, member subjected to surface treatment, and an intermediate member to be subjected to surface treatment. This invention features two beams perpendicular to a moving trajectory in an intake port opening of a cylinder head material. These beams serve as margins to prevent deformation of the opening due to material softening, thus avoiding voids during frictional stirring with a rotary tool.
