摘要： PROBLEM TO BE SOLVED: To form a blackening film in which enough radiation rate can be obtained and also adhesion is stable, by treating an iron oxalate film made on the surface in one or two kinds of atmosphere out of nitrogen gas, combustion gas, and steam. SOLUTION: An iron oxalate film is formed on the surface of a steel plate part by showering or soaking a steel plate part for a color cathode ray tube, which has iron for its main ingredient, with or in iron oxalate dilute aqueous solution of 0.2-7wt.%. Next, a blacked film is made on the steel plate part by heat-treating this part within the furnace in one or two kinds of atmosphere out of combustion gas, nitrogen gas, and steam so as to blacken it.

摘要： PURPOSE:To reduce red rusting and lowering of adhesiveness of a blackened film by throwing steel plate parts into a steam atmosphere under a high temperature while permuting the steam atmosphere into an inert gas atmosphere on the way to temperature rise or temperature holding. CONSTITUTION:Under a high temperature, steel plate parts are thrown into a steam atmosphere while the temperature is risen and held up to 450-600 deg.C in said atmosphere while permuting a steam atmosphere into an inert gas atmosphere on the way to its temperature rise or temperature holding for taking out steel plate parts. Thereby, the thickness of a blackened film to be formed can be easily controlled while reducing the red rusting due to the passage through an atmospheric furnace lying in the manufacturing process of a color cathode- ray tube which has been formerly the question and the lowering of adhesiveness of the blackened film thus improving deterioration of a withstand voltage property and suppressing defective mesh clogging of a shadow mask due to exfoliation of the blackened film almost to nothing.

摘要： PURPOSE:To reduce color discrepancy by a method wherein, regarding drilling arrangement on the corner part of a shadow mask, the more approaching the prescribed row in the direction of a vertical row from the outermost peripheral position of the drilling part, the minimum opening width in the horizontal direction of the mask is gradually reduced or the vertical bridge width is gradually increased. CONSTITUTION:Regarding the drilling arrangement on the corner part linking the long side and the short side of the drilling surface of a shadow mask 5, the vertical bridge width W2, for instance, up to the second row in the direction of a vertical row from the outermost periphery of the drilling part is increased as against the vertical bridge width W1 in the direction of the horizontal axis X of the neighboring mask, while the minimum opening width D in the direction of the horizontal axis of a thin hole 9 is set up about equal to D1 D2. Further, the vertical bridge width W2 up to the second row in the direction of the vertical row from the outermost periphery of the drilling part is increased as against the vertical bridge width of to be continued the neighboring one in the direction of the neighboring mask horizontal axis X, besides the minimum opening width D2 of the thin hole can be reduced as against the opening width D1 in order to be formed. In this way, the defective at the time of press molding of the mask 5 can be checked thus improving a material yield and mechanical strength also reducing color discrepancy on the peripheral part of the picture screen.

摘要： PURPOSE:To effectively remove only a foreign object stuck to a shadow mask without causing the thermal deformation of the shadow mask and the thermal alteration of phosphors by intermittently radiating an electron beam having a high current density to the foreign object. CONSTITUTION:An electron beam 12 is scanned with the electron gun of a cathode-ray tube over the whole face of the shadow mask 3 of the cathode-ray tube, and the luminescence state of a fluorescent screen 2 is observed with an ITV camera 28 from the outside of the cathode-ray tube. The presence of a foreign object 5 stuck on the shadow mask 3 and the position of the foreign object 5 are detected based on observation data. The spot is moved near the detected foreign object 5 while the horizontal and vertical deflection of the beam spot is adjusted by a DC deflection control circuit 22, the voltage of a focusing power source 16 is adjusted, and the electron beam 12 is focused and positioned so that the luminescence diameter becomes a preset size on the fluorescent screen 2. The electron beam 12 is intermittently radiated from a cathode 6 via grids 8, 9 and a focusing electrode 10 to remove the foreign object 5.

摘要： PURPOSE:To make it possible to remove the dirt with no remaining by providing the first dirt removal process to remove the dirt by vibrating only a shadow mask, and the second dirt removal process to make the uneven outer surface of a face panel to which the shadow mask is installed face upward and to remove the dirt by vibrating the face panel. CONSTITUTION:After the uneven outer surface of a shadow mask 8 is faced downward and the shadow mask 8 is installed to the fixing arm 18 of a vibration generator 11, the vibration generator 11 is driven continuously for a specific time. As a result, the dirt attached or piled to parts, or blocking holes is shaken off and removed. Then, after the shadow mask 8 and an inside magnetic shield 10 after the first dirt removal process is over are installed to the original face plate 4 again, the uneven outer surface of the face plate 4 is faced upward, and the vibration generator 11 is driven on condition that the center of the uneven outer surface is vacuum-adsorbed by a sucker 15, and operated continuously for a specific time. In this case, the residual dirt in the first dirt removal process is shaken off and removed. The dirt can be removed with no remaining in such a way.

摘要： PURPOSE:To assuredly prevent a trespass of a metal foil in the tube inside with the metal foil adhered to an air exchange nozzle of the tube inside by detecting a presence of a remains of the metal foil coated to a neck opening part of a funnel before the air exchange nozzle is inserted into the tube inside by a through type metal sensor. CONSTITUTION:A color cathode-ray tube 4 is made to stop at the place where a through type metal sensor 7 of a ring or rectangular state is mounted with a conveyer frame 5 moved. A presence of a remains of a metal foil 2 in a neck part 1A is made to be detected with the through type metal sensor 7 penetrated into a neck part 1A of a funnel 1 and moved in the x-y direction in the stopped position. And the metal foil 2 is completely eliminated by an air-blow means etc. When the remains of the metal foil 2 exist, and only a color cathoderay tube 4 in which the metal toil 2 is completely eliminated is shifted to next pipe inside air exchange place via a movement of the frame 5. This enables carrying of a part of the metal foil 2 adhered to a nozzle inserted to the tube inside for the tube inside air exchange is assuredly to be prevented.
