摘要： A novel electron gun for the color picture tube is disclosed, which comprises at least a cathode for emitting three electron beams in alignment and focusing electrodes for focusing the electron beams emitted from the cathode. The forcusing electrodes include first and second focusing electrodes for passing electron beams. The first focusing electrode includes a plurality of perpendicular plate electrodes arranged in such a manner as to sandwich the electron beams along the direction of arrangement thereof after being passed through the passage apertures and rim electrodes surrounding the perpendicular plate electrodes. The second focusing electrode includes a couple of horizontal plate electrodes arranged in such a manner as to hold the electron beams along the direction perpendicular to the direction of arrangement thereof after being passed through passage apertures and extending in opposed relationship with the perpendicular plate electrodes and rim electrodes along tht electron gun axis. The resolution of the peripheral parts of the display surface of the picture tube is thus improved and the assembly of the electron gun thereof is facilitated.

摘要： An electron gun for a color picture tube has beam generators for generating three electron beams and directing them toward the fluorescent screen along three paths which are parallel with each other on the same plane, and at least one pair of electrode surfaces each having three apertures centered with the three paths for forming independent main lenses so as to focus the electron beams on the fluorescent screen, the electrode surfaces being spaced apart from each other. Provided for the electrode surface are cylindrical shield members centered with the apertures and extending from the apertures in opposition to the opposing electrode surface. Outer ones of the cylindrical shield members have each an end surface inclined with respect to the center axis of the aperture so as to form inclined electric fields effective to converge the outer beams to one point to which the central beam converges.

摘要： An in-line type electron gun assembly has a cathode unit for producing a central electron beam and two side electron beams and first and second electrode units. Each of the first and second electrode units has a cylindrical member of a non-circular elongated cross section and a plate member provided on the inner wall of the cylindrical member so as to be joined therewith to define three electron beam passage holes juxtaposed, within the cylindrical member, in a direction parallel with a lengthwise direction of the elongated cross section of the cylindrical member. The plate member of each electrode unit has at least one hole therein serving as an electron beam passage hole for the central electron beam. The diameter of the hole in one of the plate members of the first and second electrode units measured in a direction perpendicular to the lengthwise direction of the elongated cross section of the cylindrical members is different from the diameter of the corresponding hole in the other plate member measured in a direction perpendicular to the lengthwise direction of the elongated cross section of the cylindrical members for optimizing the central electron beam shape and for emphasizing one of a focusing and diverging function.
