Latest Patents

Nagai holds a patent for an "Apparatus and method for manufacturing monocrystals." This invention involves a monocrystal producing device that utilizes a pulling-down method. The device continuously supplies a raw material melt into a crucible, allowing for the growth of crystals. By employing a powdery raw material supplying device, the raw material is melted on a premelt plate inside an electric furnace. This process generates a raw material melt that drops into the crucible. Additionally, dry air is introduced into the powdery raw material tank to prevent moisture, and a cooled transferring tube is used to avoid filling issues. This innovative method enables the production of monocrystals with stable chemical compositions, large diameters, and extended lengths at a lower cost.
