Title:
METHOD AND DEVICE FOR CASTING CONDUCTOR OR SEMICONDUCTOR MATERIAL
Document Type and Number:
Japanese Patent JPS6152962
Kind Code:
A
Abstract:
A method and apparatus is disclosed for casting conductive and semiconductive materials. The apparatus includes a plurality of conductive members arranged to define a container-like area having a desired cross-sectional shape. A portion or all of the conductive or semiconductive material which is to be cast is introduced into the container-like area. A means is provided for inducing the flow of an electrical current in each of the conductive members, which currents act collectively to induce a current flow in the material. The induced current flow through the conductive members is in a direction substantially opposite to the induced current flow in the material so that the material is repelled from the conductive members during the casting process.
