    摘要： In an electron gun assembly, three eletron beams emitted from cathodes (KR, KG, KB) are passed through an electrode arrangement (10, 60, 90) in which two inter­mediate electrodes (70, 80) are arranged between focus­ing are accelerating electrodes (50, 60). A focusing voltage which is varied depending on an deflection of the electron beam is applied to the focusing electrode (50) and an accelerating voltage is applied to the acce­lerating electrode (60). A resistor (100) is connected between the accelerating electrode (60) and the earth through a variable resistor (105) and intermediate points of the reisistor (100) are connected to the intermediate electrodes (50, 60). Thus, convergent and divergent lenses (200, 210, 300, 310) are formed between the focusing electrode (50) and the intermediate elec­trode (70) and between the accelerating electrode (60) and the intermediate electrode (80). The lens powers of the convergent and divergent lenses (200, 210, 300, 310) are varied in accordance with the adjustment of the variable resistor (105).

    摘要： An electron gun for color-picture tube device comprises a final accelerating electrode (9) and a focusing electrode (8a, 8b) divided into plural electrode units in the axial direction of the tube. A first focusing electrode unit (8b) adjacent to the final accelerating electrode (9) is connected to a second focusing electrode unit (8a) adjacent to the first focusing electrode unit (8b) through a resistor (11). A focusing voltage being changed in synchronous with the deflection of an electron beam is applied to the first focusing electrode unit (8b). The resistor (11) is used for removing the a.c. components from the focusing voltage. Then, the removed focusing voltage is applied to the second focusing electrode (8a). For the electron beam deflected on the peripheral part of the screen, a quadrupole lens is formed. On the first focusing electrode unit side opposite to the second focusing electrode unit are formed first electron beam path holes (13) whose major axes extend horizontally. On the second focusing electrode unit side opposite to the first focusing electrode unit are formed second electron beam path holes (12) whose major axes extend vertically. As a result, the quadrupole lens serves to suppress a halo portion.

    摘要： An image display apparatus includes a face plate (2) including a low-potential electrode (24) and a plate-like spacer (40) including a longitudinal-direction end (401). The low-potential electrode (24) is set at a lower potential than that of a resistive anode (17) and is disposed between the resistive anode (17) and a feed electrode (21). The longitudinal-direction end (401) of the plate-like spacer (40) is disposed between the resistive anode (17) and the feed electrode (21) so as to overlap the low-potential electrode (24).
