| 20110015079 | METHOD OF FORMING PRECURSOR SOLUTION FOR METAL ORGANIC DEPOSITION AND METHOD OF FORMING SUPERCONDUCTING THICK FILM USING THE SAME - The present invention relates to a method of forming a precursor solution for metal organic deposition and a method of forming a superconducting thick film using the same. A first precursor comprising one rare earth element, a second precursor comprising barium, and a third precursor comprising copper are dissolved into acid to form a compound solution, the compound solution is dissolved into solvent to form a pre-precursor solution, and the solvent of the pre-precursor solution is evaporated to form a precursor solution with the increased viscosity. A sufficiently thick film can be formed without any cracking through only one-time coating. | 01-20-2011 |
| 20100107979 | APPARATUS FOR CONTINUOUS FABRICATING SUPERCONDUCTING TAPES - Provided is an apparatus for continuously fabricating superconducting tapes. An evaporation using drum in dual chamber (EDDC) method is suitable for mass production of high-temperature superconducting tapes. However, the EDDC method is limited to fabrication of high-temperature superconducting tapes having a limited length. In an attempt, high-temperature super-conducting tapes having a sufficiently large length can be fabricated using the EDDC method by releasing a long high-temperature superconducting tape from one reel and winding the long high-temperature superconducting tape around the other reel. In this case, it is important to stably move a high-temperature superconducting tape spirally wound around a drum from one reel to the other reel. Therefore, the provided apparatus uses endless tract belts separately disposed around a drum to stably and continuously move a high-temperature superconducting tape spirally wound around the drum along the centerline of the drum from one reel to the other reel. | 05-06-2010 |
