Abstract: PROBLEM TO BE SOLVED: To improve the assembling precision of an electron gun by setting each pair of pillows movable to a support columnar body. SOLUTION: A part of each electrode is successively stacked from the lower part within a body magazine part 30. In this case, the reference surface is the inside of the reference-side body magazine part 30a in X-direction, and automatically determined by V-shape of each of six pillows 32, 34, 36, 38, 40, 42 positioned by the reference surface of a magazine part 30b in Y-direction. For the X-directional. position, a spacer 17 mounted on the bottom pillow 32 of the six V pillows is determined by its positioning pin 32a. Each V-shaped pillow 32, 34, 36, 38, 40, 42 is movable in X-direction to a set block 50.

Abstract: PROBLEM TO BE SOLVED: To heat a multi-form glass uniformly. SOLUTION: A pin is protrusively provided at the side of a plurality of parts of an electron gun for CRT fixed onto a base 10 in the vertical arrangement, and a multi-form glass 41 mounted on a bed 43 is softened by the heat from a gas burner 26, bitten into the pin and left for cooling naturally so that the plurality of parts are coupled firmly. When the glass 41 is heated by the gas burner 26, the entire area is heated uniformly even in case the softened glass 41 is put in a bent condition in compliance with the shape of the bed 43 by reciprocating the burner 26 fore and aft in the neighborhood of the glass 41.

Abstract: PURPOSE:To sufficiently remove fluorescent material slurry sticking to a skirt part internal wall over the total periphery of a panel by moving a cleaning nozzle unit moved to be associated with a copying unit between the first/second cleaning positions. CONSTITUTION:In a condition press contact with the peripheral part of a panel P rotated on its own axis by a panel rotating means, a copying unit 2 performs copying action, to move a cleaning nozzle unit 3 associated with this action in parallel to a seal edge surface S while fixedly holding a distance from a skirt part internal wall of the panel P. Simultaneously with this operation, in the case of cleaning a short side of the panel P, the unit 3 is advanced to the first cleaning position A by the first drive means 37, 38. In the case of cleaning a long side of the panel P, the unit 3 is advanced to the second cleaning position B, positioned in a panel internal surface side from the first cleaning position A, by the second drive means 29 to 42. In this way, fluorescent material slurry in the skirt part internal wall can be removed over the total periphery of the panel P.

Abstract: PROBLEM TO BE SOLVED: To aim at improvement in off-centering quality of a cathode-ray tube by enabling to correctly index a position of its center, even if a shape of a cross section of a supported portion of the cathode-ray tube has a tendency to deform. SOLUTION: The positioning method is used in a case where a position of a funnel 2 is indexed of its position by supporting a funnel outer circumference portion 2a of the cathode-ray tube 1. By grasping a deformation tendency of the funnel 2 of the position-indexed cathode-ray tube 1, an area having a small tendency to deform in the outer circumference portion of the funnel, is specified. The above funnel 2 is indexed with its position in a condition in which the supported position 14 is allotted within the limits of the specified area.
