Latest Patents
Yamamura's latest patents focus on innovative methods for casting dental metals. One of his notable inventions involves a casting apparatus that includes a hermetically sealed casting chamber. This chamber houses an arc electrode positioned above a crucible made of electrically conductive material. The method entails placing a dental metal ingot on the crucible, evacuating the chamber to create a vacuum, and feeding a small amount of inert gas to induce arc discharge. This process melts the ingot, allowing the molten metal to be poured into a mold. An additional amount of inert gas is then rapidly fed into the chamber to increase internal pressure, ensuring optimal casting conditions.
Another patent by Yamamura describes a similar method but features a melting chamber divided from a mold chamber by a partition wall. This design allows for effective communication between the melting and mold chambers, enhancing the casting process. The innovative use of inert gas and vacuum conditions in both patents demonstrates Yamamura's commitment to improving dental metal casting techniques.
