A glasses-type shutter holder may include left and right temple parts connected respectively to left and right frame end parts of frame. The left and right temple parts may be foldable respectively with respect to the left and right frame end parts in accordance with movement, for each frame end part and temple part pair, of a contact position at which a movement part provided with one of the temple part and the frame end part of the pair is in contact with a contact part of the other of the temple part and the frame end part of the pair. For each of the pairs, the contact part is in contact with the movement part when the temple part is unfolded to a maximum degree, and a maximum degree of opening of the temple part is varied in accordance with the movement of the movable part.

A method of making a steel sheet for a tension mask, including the steps of: hot rolling a steel consisting essentially of, by weight %, 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: 0.010% or more, and the balance of Fe; and annealing the cold rolled steel sheet, followed by a secondary cold rolling at a reduction rate of 35% or higher. The steel sheet produced by this method shows excellent creep resistance during blackening treatment and excellent magnetic shielding property with an anhysteretic permeability of 3400 or more at a DC bias magnetic field of 0.35 Oe, and therefore causes no color-deviation when applied to the tension mask.

In a casting process using a resin core, sometimes molten resin remains in a cast product after the steps of withdrawal of the resin core from the cast product. In order to solve the problem, as a material of the resin core, a resin which is hard and not deformed against high temperature and high pressure of molten metal until the molten metal is solidified and is softened with an increase of temperature beyond the temperature at which the metal is solidified is used. The resin core is withdrawn from the cast product after it is softened but before it is melted. The softened core is pulled out from the cast product without being broken apart.

Disclosed is a cathode ray tube and a intensity controlling method achieving a reduced amount of factors for correcting intensity prepared and capable of performing proper intensity control so that the joint portion of split picture planes is inconspicuous from a viewpoint of intensity. With respect to the direction of overlapping a plurality of split picture planes, only correction factors at representative signal levels are pre-stored as a basic factor table. Any of the factors at the other signal levels is obtained by performing an interpolating operation using the basic factors in the basic factor table. The value of the signal level of a video signal referred to when the correction factor in the overlapping direction is obtained is changed by using a shift factor associated with the pixel position in the direction orthogonal to the overlapping direction. The basic factor is thereby changed according to the pixel position in the orthogonal direction.
