PROBLEM TO BE SOLVED: To provide a light-weight cathode-ray tube by making a copper wire coil which is installed in the cathode-ray tube light. SOLUTION: In the cathode-ray tube, a light-weight cathode-ray tube is obtained by changing a deflection coil from the copper wire to aluminum wire. Thus the cathode-ray tube, in turn, a television receiver is made significantly light in weight. COPYRIGHT: (C)2004,JPO
