Latest Patents
Yamauchi's latest patents include an "Apparatus for producing single crystals." This method involves withdrawing a semiconductor or dielectric material from its molten state while allowing it to grow into a single crystal solid. A die, heated to a temperature higher than the solidifying point of the melt, is disposed at the melt withdrawing outlet, allowing the single crystal to be withdrawn through the die. Another notable patent is for the "Fabrication of superconducting oxide wires by powder-in-tube method." This method discloses a process for producing an oxide superconducting wire, where a preformed copper oxide superconducting powder is continuously filled into a tube precursor. The tube precursor is formed into a tube by bending and welding, and the resulting tube is drawn to a reduced cross-section and further heated to sinter the packed powder, forming the finished oxide superconducting wire.
