Abstract: PURPOSE:To reduce variations in characteristics due to heat generation of a metallic member by making the resistant value of a part facing a metallic member, of the resistance pattern of a resistor, relatively smaller than the resistant value of other parts. CONSTITUTION:In an electron gun, a resistor 30 extending from the side of a cathode K to the side surface of a convergence cup C is arranged along the back surface of one side insulating support 11. Furthermore, a linear metal member 13 is annularly attached to the third grid G3 just like hemming a pair of insulating support 11 and the resistor 30. The resistance pattern 33 of the resistor 30 is composed of a high resistance part 38 and a low resistance part 39 which is formed in a position facing the metal member 13. Even if the metal member 13 is heated by high frequency heating, the resistance value of the part facing the metal member 13 changes only a little, variation in a resistance division ratio can be made remarkably small, and the third and the fourth grids G3 and G4 can be provided with their set voltages, respectively.

Abstract: PURPOSE:To provide excellent resolution by allowing an electron beam to receive a converging effect relatively stronger in the vertical direction than in the horizontal direction on the low potential side of an electron lens, and to receive a dispersive effect relatively stronger in the vertical direction than in the horizontal direction on the high potential side of the lens. CONSTITUTION:The isopotential distribution in the vertical direction inside cup-shaped electrodes 132, 141 is such that the isopotential line in the central part protrudes into electrode because of influence of electric field correcting members 160, 161, 170, 171. That is, the radius of curvature of the isopotential line in the vertical direction becomes greater than in the horizontal direction, and this trend is more distinctive in the cup-shaped electrode 141 having a shorter distance between the electric field correcting members. Because no electric field correcting plate exists in the horizontal direction, the radius of curvature of the isopotential line is smaller than in the vertical direction. By other words, both the converging and dispersing effects are applied relatively stronger in the vertical direction, while these effects act in the horizontal direction relatively weaker. This accomplishes enhanced resolution in the peripheral area of a screen without causing drop of the resolution in the central part of the screen.

Abstract: PURPOSE:To provide vertical and horizontal adjustability for an electron beam spot substantially independently from each further by forming an asymmetrical converging electric field stronger in the vertical direction than in the horizontal direction. CONSTITUTION:Converging electric field penetrating No.5 electrode 50 has a common isopotential line for the central hole 542 and side holes 541, 543. The radius of curvature of the isopotential line in the vertical direction becomes smaller than in the horizontal direction because of influence of side walls 55 of electrode. That is, the converging effect in the vertical direction becomes relatively stronger than in the horizontal direction. In the same manner the dispersive electric field penetrating No.6 electrode 60 in the vertical direction becomes relatively stronger than in the horizontal direction. Thereby coordination of the vertical and horizontal directions of electron beam is not needed at the time of focus adjustment, and the two directions can be adjusted substantially independently.

Abstract: PURPOSE:To enhance the resolution at the peripheries of the screen without causing drop of the resolution in the center of screen by impressing on those of the electrodes constituting focusing electrode which are not impressed with the focusing voltage through a resistor in which the focusing voltage is arranged within the tube. CONSTITUTION:Focusing voltage is impressed on No.1 focusing electrode 13a through a resistor 16 after being impressed on No.2 focusing electrode 13b. While electron beam is situated in the center of the screen, the No.1 focusing electrode 13a and No.2 focusing electrode 13b are at the same potential, and meantime no four-polar lens is formed and therefore the electron beam is focused by a main lens. When the electron beam is deflected to the peripheries of the screen, on the other hand, a potential difference is generated between the No.1 and No.2 focusing electrodes 13a, 13b, and meantime a four-polar lens is formed and therefore the electron beam receives the focusing effect horizontally from this four-polar lens and the main lens and receives dispersion effect in the vertical direction. Accordingly strain as overconvergence in the vertical direction due to deflection abberation can be eliminated with only the electron beam in vertical direction as insufficient convergence.
