Abstract: A method for producing a steel sheet for a tension mask which comprises the steps of hot rolling a steel having the chemical composition in wt.%: C: less than 0.1 %, Si: 0.05 % or less, Mn: 0.4 to 2 %, P: 0.03 % or less, S: 0.03 % or less, sol.Al: 0.01 % or less, N: 0.01 % or more, balance: substantially Fe, cold rolling the hot rolled steel sheet followed by annealing, and subjecting the resulting steel sheet to a secondary cold rolling at a reduction in thickness of 35 % or more. A steel sheet produced by the use of the above method exhibits excellent resistance to creep in blackening processing and also has an excellent magnetic shielding property such that it exhibits a non-hysteresis magnetic permeability of 3400 or more at a DC bias magnetic field of 0.35 Oe, and thus causes no color divergence when used for a tension mask.

Abstract: A steel sheet for a heat shrink band having a non-hysterisis magnetic permeability in a magnetic field of 0.35 Oe of 15000 or more and a yield stress of 24 kgf/mm or greater. The steel sheet for a heat shrink band can be produced by a method comprising a step of subjecting a steel containing C in an amount of 0.01 to 0.15 wt % to a hot or cold rolling, a step of annealing the rolled product at 650 to 900 DEG C, and subjecting the annealed product to temper rolling at a draft of 1.5 % or less. The steel sheet for a heat shrink band can be used for producing a cathode-ray tube which is almost free from the occurrence of color slippage and does not suffer the deformation of its panel face.

Abstract: PURPOSE:To reduce the number of high-voltage and medium-voltage cables by building a division resistor in a cathode-ray tube. CONSTITUTION:The resistive body 12 of a division resistor for supplying voltage to an electron gun within a cathode-ray tube is arranged in a ceramic base board 11, on which the coat glass 13 of an overcoat is arranged and baked, and built in within the cathode-ray tube. Therefore, as compared with the case of being mounted outside, the division resistor can be reduced to simplify the external circuit arrangement of the cathode-ray tube and to reduce the number of a high-voltage and a medium-voltage cable. Incidentally, a similar effect can be obtained with a part of the division resistor built in.
