Abstract: A terminal joining structure includes a terminal having a tubular barrel portion and a flange portion that is integrally formed at the axis-direction end of the barrel portion, a conductor substrate on which is opened a through-hole for inserting the barrel portion, and a ring that fits on the barrel portion on the opposite side of the conductor substrate. On the barrel portion is formed a taper that increases in diameter toward the flange portion. The diameter of the larger-diameter portion of the taper is larger than the inner diameter of the through-hole. The terminal is caulked to cause radially outward expansion of an end part of the barrel portion, which passes through the ring, on the opposite side of the conductor substrate and is fixed to the conductor substrate together with the ring.

Abstract: As a method for maintaining a frame having a mask, at a predetermined position inside a panel of a color cathode-ray tube, provided are a first plate type—elastic body which is fixed to the panel through a stud pin adhering to the panel, a second plate type—elastic body which is fixed to the frame, a third plate type—elastic body which is provided between the first plate type—elastic body and the second plate type—elastic body, a bent part, protruding in the direction of the first plate type—elastic body, which is provided in a part of the third plate type—elastic body, a space being equal to or less than 1.0 mm between the bent part and a slant plane of the first plate type—elastic body, and a space being equal to or less than 1.0 mm between an end part of the third plate type—elastic body and the second plate type—elastic body.

Abstract: A frame (3) for supporting a color selection electrode body (2) under tension includes a pair of first frames (10) arranged in the horizontal direction and a pair of second frames (20) arranged in the vertical direction. The first frames (10) are each formed by bending a sheet material into a substantially triangular sectional shape, whose three side faces are formed by a first support part (12), a second support part (14) and a third support part (16). Projections (30) each having a shear plane (32) are formed in an inner position of the one side edge of the first support part (12). The other side edge (16a)) of the third support part (16) is arranged to be in contact with a main surface of the first support part (12) and the shear plane (32) of each of the projections (30). Shearing force acting between the other side edge (16a)) of the third support part (16) and first support part (12) is received by the projections (30).

Abstract: A color selection mask is provided with an aperture region including a slit region (21) and bridge regions (22). The bridge regions (22) are provided on top and bottom ends of the aperture region. In the slit region (21), slits (123) through which electron beams pass and strips (124) are arranged alternately. The strips (124) extend into the bridge regions (22), where bridges (25) for connecting adjacent two of the strips (124) and through holes (122) through which electron beams pass are provided.

Abstract: A tensioned mask structure for a color CRT includes a color-selecting mask that is formed with a plurality of electron beam passing holes therein, a mask frame on which the color-selecting mask is mounted, and a vibration-attenuating mechanism in contact with the color-selecting mask to damp vibration of the color-selecting mask. The color-selecting mask includes an effective mask area having a slit region and a slot region. The slit region has a plurality of long narrow elements that extend in a vertical direction of a screen of the CRT and are aligned to define slit-like holes between adjacent long narrow elements. The slot region has a plurality of slot-like holes shorter than the slit-like holes, the slot-like holes extending in the vertical direction. The slit region is formed in an area except a left peripheral portion and a right peripheral portion of the effective mask area.

Abstract: A method for manufacturing CRT interior parts made of material such as of iron or steel has the steps of: introducing hydrocarbon and air into a conversion furnace, thereby producing an exothermic gas; cooling the exothermic gas to a predetermined temperature higher than a dew point of the exothermic gas; and introducing the exothermic gas at a temperature higher than the dew point into a blackening furnace which houses the CRT interior parts, thereby producing a blackened film on a surface of each of the CRT interior parts. The blackened film is mainly consisting of Fe.sub.3 O.sub.4. The temperature of the exothermic gas, when introduced in the blackening furnace, may be higher than a boiling point of each component composing the exothermic gas.
