摘要： A molding lost foam pattern made out of synthetic resin is decomposed and gasified by molten metal. The molding lost foam pattern includes a runner portion foam pattern extending vertically. The runner portion foam pattern includes a hollow portion and a base portion. A plurality of short-sized gate portion foam patterns are provided on external surfaces of the hollow portion of the runner portion foam pattern, and a product portion foam pattern is connected to the external surfaces of the hollow portion through the plurality of short-sized gate portion foam patterns. A method of making the molding lost foam pattern is also disclosed.

摘要： A surface treating and smoothing method of surface-treating and smoothing a sliding member including steps of finishing the sliding member by pressurized particle containing fluid blasting to a sliding surface with surface roughness ranging approximately 0.02 to 0.7 &mgr;mRa after pre-finishing it to a surface with surface roughness lower than lower one of a surface roughness of a counter member and 0.2 &mgr;mRa, treating the sliding member by salt-bath nitrocarburizing so as to provide the sliding member with surface hardness higher than surface hardness of the counter member but lower than 1500 Hv, and driving the sliding member and the counter member so as to slide on each other for running-in, thereby smoothing the surfaces of the sliding member and the counter member.

摘要： A pressure molding method and apparatus uses a mold with a casting cavity and a pouring gate through which a molten metal is fed into the casting cavity. After feeding a molten metal into the mold through the pouring gate to fill the casting cavity and pouring gate, a cap member is placed on the mold to bring its open end into contact with a dead head of the molten metal in the pouring gate of the mold so as to form an air-tightly sealed chamber between the cap member and dead head of the molten metal. Pressure is supplied into the sealed chamber to force the molten metal in the mold through the dead head.
