    摘要： A method for manufacturing a color cathode ray tube capable of surely applying a predetermined tension force to a shadow mask and preventing the generation of wrinkles and a manufacturing apparatus of the color cathode ray tube. The method includes applying a compression force to a mask frame formed in a frame shape in the direction in which a gap between at least a pair of facing sides is reduced; and welding and fixing a shadow mask to the upper surface of the mask frame with a tension force applied in the direction opposite to the compression force. In this method, a place to which the compression force is applied is the upper end of the external surface of the mask frame. Thus, a repulsion force in the direction in which a shadow mask is stretched can surely be obtained after the compression force is released, as compared with the case where the same level of compression force is applied to the lower end. Consequently, it is possible to prevent the deterioration of the tension force of the shadow mask.

    摘要翻译： 一种制造彩色阴极射线管的方法，该彩色阴极射线管能够确实地向荫罩施加预定的张力并防止皱纹的产生和彩色阴极射线管的制造装置。 该方法包括：在至少一对相对侧之间的间隙减小的方向上对形成为框状的荫罩框架施加压缩力; 并且以与压缩力相反的方向施加的张力将荫罩焊接并固定到荫罩框架的上表面。 在该方法中，施加压缩力的地方是荫罩框架的外表面的上端。 因此，与向下端施加相同水平的压缩力的情况相比，在压缩力被释放之后，可以确保在荫罩拉伸方向上的排斥力。 因此，可以防止荫罩的张力的劣化。

    摘要： Welding is conducted by rolling a roller electrode of a roller-type resistance welder while contacting an electrode surface of the roller electrode against an outer edge of the mask frame via the shadow mask. This method eliminates the need for complex control, and allows smooth and reliable welding at predetermined positions with a simple configuration. By forming the weld nugget on the side of the edge, a flat portion remains when the shadow mask is torn off the mask frame in case of a failure of the shadow mask. Thus, a second welding with a flat portion of the original height is possible, and the mask frame can be reused with the same precision for the welding position.

    摘要： After adhesive resin is applied to a surface of a flat panel, a front panel is glued thereto. One side of the front panel is contacted to the adhesive resin layer with the front panel tilted toward the surface of the flat panel. Then, the front panel is moved slowly to be close and parallel to the front panel. Finally, the front panel is pressed to the surface of the flat panel. Afterward, the adhesive resin is hardened. It is preferable that the thickness of the adhesive resin applied to the surface of the flat panel is decreasing from the side to which the side of the front panel is contacted, to the opposite side. By the above-mentioned method, an image display apparatus having multilayer structure comprising of a flat panel for displaying image, an adhesive resin layer and a front panel can be manufactured efficiently.
