In Keun YU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10986701
    Abstract: The present invention relates to a superconducting magnet apparatus using movable iron core and induction heating apparatus thereof. The superconducting magnet structure is composed by including a pair of superconducting magnets and a pair of movable iron cores which are symmetrically located with respect to the heating target product located between the superconducting magnets and a part of which move through the cutouts of the superconducting magnets. And the distance from the superconducting magnets is adjusted by moving the movable iron cores. Further, the present invention manufactures an induction heating apparatus by using the superconducting magnet structure.

  • Patent number: 9012780
    Abstract: Provided are a three-phase coaxial superconducting power cable and a structure thereof. A certain space is formed between adjacent superconducting wires of a superconducting layer (disposed at an outer portion) having more superconducting wires among a plurality of superconducting layers, and another wire is disposed in the space, or the superconducting wires of the respective superconducting layers are disposed to have different critical currents. Accordingly, a waste of superconducting wires is prevented, and the optimized three-phase coaxial superconducting power cable is provided.
