は同一または相当部分を示す。Figure 1 shows a CRT using a CP magnet. Figure 2 is a side view showing the assembled state of the deflection yoke and CP magnet. Figure 2 is a side view showing the assembled state of the CRT deflection yoke and CP magnet sheet when a CP magnet sheet is used. Figure 3 is a side view showing the assembled state of the CRT deflection yoke and CP magnet sheet. A diagram showing a correction magnetization pattern, and FIG. 4 is a diagram showing a magnetization pattern when a CP magnet sheet is magnetized from an apparently non-magnetized state. DESCRIPTION OF SYMBOLS 1...CRT, 4...Neck tube part, 5...Electron gun, 6...Deflection yoke, 8...CP magnet sheet, 13...Non-magnetized pattern. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

電子ビームをパネルガラスの中央部で一点に集束させる
とともに、３本の電子ビームの軌道を変化させて色純度
を補正する補正用マグネットシートをネック部に備えた
陰極線管であって、マグネットシートがネック部に装着
される以前において、その厚さ方向に微小間隔でＮ極お
よびＳ極に交互に着磁されて見かけ上は無着磁状態にさ
れたのち上記ネック部に装着されていることを特徴とす
る陰極線管。For correction that focuses the three electron beams corresponding to red, green, and blue emitted from the electron gun to a single point at the center of the panel glass, and also changes the trajectory of the three electron beams to correct color purity. This is a cathode ray tube that has a magnet sheet in its neck, and before the magnet sheet is attached to the neck, it is magnetized alternately to N and S poles at minute intervals in the thickness direction, making it appear to be completely invisible. A cathode ray tube characterized in that the tube is magnetized and then attached to the neck portion.
