    Abstract: This invention concentrates multiplex electron-beams at all the points of a scanning raster without using a dyanmic convergence apparatus. The TV set(10) includes a glass-tube(11) whose front side has a surface panel (12). The inside of the surface panel is coated with red, green, and blue fluorescent elements (13) (13a) (13b).

    Abstract: An evacuated envelope has a rectangular addressing section and a gun section at one edge of the addressing section. The addressing section includes front and back walls in closely spaced, parallel realtion and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes gun structure that will selectively direct electrons along each of the channels.

    Abstract: A cathode ray tube which increases self-supporting force and prevents hear-expansion of shadow mask caused from electron beam in beginning of operation includes a shadow mask shaped wave for which peaks and bottoms are parallel with each other and have hundreds of thousand of holes. A distance between pitch and pitch of wave is at least two times of a distance between hole and hole.
