摘要： In an electron gun for a cathode ray tube in which a focus electrode group includes a single platelike electrode having three apertures arrayed in one plane and a thickness equal to a depth of each of the three apertures, a tapered surface is formed on the entrance side and/or exit side of each of the three apertures, the tapered surface having a diameter larger than the aperture diameter and having a linear or curved shape in cross section, and a step which extends in the direction of the depth is formed around an aperture periphery of the tapered surface. With this constitution, the concentricity between each of the tapered surfaces and a respective one of the apertures can be measured with high precision on the basis of the boundary between each of the tapered surfaces and the corresponding one of the steps, thereby improving the precision of measurement of the concentricity between each of the apertures formed in the platelike electrode and the tapered surface formed around the aperture periphery.

摘要： The profile lines of plate-like grid electrodes are formed by a first punching step and separation lines of the plate-like grid electrodes are formed by a subsequent punching step. The angle of a crossing portion formed by the profile line and the separation line is set to not less than 70 degrees and not more than 110 degrees. Due to such a constitution, burrs on the plate-like grid electrode which constitutes an electron gun of a color cathode ray tube can be reduced so that the quality of the cathode ray tube can be enhanced and the manufacturing time of the cathode ray tube can be shortened.

摘要： A cathode ray tube has a phosphor screen and an electron gun. The electron gun includes an electron beam generating section and an electron beam focusing section for focusing an electron beam from the electron beam generating section onto the phosphor screen. The electron beam generating section and the electron beam focusing section are mounted in predetermined spaced relationship on plural insulator support rods. The electron beam focusing section includes at least one compound electrode formed of a first electrode member, a second electrode member and a plate-like electrode member sandwiched therebetween. The plate-like electrode member is fabricated from a material thicker than materials from which the first and second electrode members are fabricated. The plate-like electrode member is laser-welded to the first and second electrode members at points of edges of the first and second electrode members. The points of edges of the first and second electrode members are positioned so as not to face mounting tabs of the plate-like electrode member embedded in the insulator support rods, and edges of the plate-like electrode member extend by an approximately equal distance outwardly beyond the points of edges of the first and second electrode members welded to the plate-like electrode member.

摘要： A cathode-ray tube having an electron gun which includes an electrode plate (E) in which a portion having three beam passage holes (H) and a portion having bead supports (S) are formed as a unitary or one piece structure, the two portions having different thicknesses (T.sub.1, T.sub.2), and the steps being inclinedly formed along the boundaries of the two portions. Since the portion having beam passage holes and the portion having bead supports are formed as a unitary or one piece structure easily and highly precisely in the electrode plate, the conventionally employed process of welding can be omitted, and thereby the productivity is raised and the manufacturing cost is decreased. Moreover, use of the material having the steps formed in advance contributes to increasing the productivity and preventing the machining tools from being damaged during the press-forming.
