Abstract: The present invention relates to a method of preparing an ABS graft copolymer and a method of preparing a thermoplastic resin composition including the ABS graft copolymer. More specifically, the present invention relates to a method of preparing an ABS graft copolymer, in which a predetermined amount of a vinyl aromatic compound and a predetermined amount of a vinyl cyanide compound are grafted to a small-diameter rubber latex before enlarging particle size of the small-diameter rubber latex is performed, and then enlarging particle size of the small-diameter rubber latex is performed by adding a certain amount of a polymer coagulant, and to a method of preparing a thermoplastic resin composition including the ABS graft copolymer. According to the present invention, latex stability may be improved, and an ABS graft copolymer having excellent impact resistance may be prepared.

Abstract: Disclosed is an electron gun which includes at least one pair of plate electrodes for focusing and accelerating thermal electrons, and at least one pair of cup-shaped focusing electrodes for focusing an electron beam coming out of plate electrodes, wherein the focusing electrodes have two or more electrodes embedded in a bead glass by means of fusing. The embedded electrodes are arranged perpendicularly to each other. A final focusing electrode has a cut groove at both ends, which contains the embedded electrodes. The inside of the final electrode is provided with an internal electrode having the embedded electrodes extended towards the outside through the cut grooves.

Abstract: An electron gun for a color cathode ray tube taking a multi-level focusing form includes a focusing electrode and a pre-focusing electrode. The distances between the centers of the apertures of the focusing electrode are larger than the distances between the corresponding apertures of the pre-focusing electrode. The electron gun further includes a post-focusing electrode. The distances between the centers of the apertures of the focusing electrode are larger than those of the corresponding apertures of the post-focusing electrode. But, the center distances between the apertures of the pre-focusing electrode are equal to the center distances between the corresponding apertures of the post-focusing electrode. The post-focusing electrode is partitioned from the focusing electrode.
