Abstract

A CATHODE RAY TUBE INCLUDES A PAIR OF PLAT MEMBERS (7) FACING EACH OTHER, A PAIR OF SUPPORTERS (14) ADHERED TO THE RESPECTIVE PLATE MEMBERS (7) TO SUPPORT THE PLATE MEMBERS (7), AND A SHADOW MASK (6) ADHERED TO THE RESPECTIVE PLATE MEMBERS (7) WHILE BEING APPLIED WITH TENSILE FORCE. THE SUPPORTERS (14) HAVE CRANK-SHAPED STEPS (15) FORMED TO PROTRUDE TOWARD THE SHADOW MASK(6). THEREBY, AN INTERNAL MOMENT OF A SHADOW MASK STRUCTURE (16) CAN BE DECREASED, AND THUS DISPLACEMENT OF THE SHADOW MASK (6) IN THE AXIAL DIRECTION IS SUPPRESSED EVEN WHEN THE SHADOW MASK (6) IS EXPANDED BY HEAT GENERATED BY IMPACT OF ELECTRON BEAMS, AND Q-VALUE DEVIATION IS SUPPRESSED AS WELL. MOREOVER, SINCE THE CRANK-SHAPED STEPS (15) ARE HELPFUL IN BLOCKING A TRANSVERSE CLEARANCE WITH A FERROUS MATERIAL, THE MAGNETIC PROPERTIES CAN BE IMPROVED.
