A multilayer wiring structure comprising a plurality of groups of patterns each having a multiplicity of wirings formed on the opposite sides of an intervening insulation film. The intervening insulation film is formed with a void exposed to both an upper pattern of a multiplicity of wirings and a lower pattern of a multiplicity of wirings, the upper and lower patterns being formed on and beneath the intervening insulation film and arranged to form a matrix. The void extends longitudinally across one of the patterns, and the upper and lower patterns are connected together through the void at crossing points of the matrix.

A color picture tube is disclosed which comprises an electron gun for emitting an electron beam and a shadow mask including a plurality of slots and a plurality of bridges each interposed between adjacent slots along the longitudinal axis thereof. When X and Y axes are assumed passing through the central point of the surface of the shadow mask in the direction of horizontal deflection of the electron beam and passing through the same central point in the direction perpendicular to the X axis, respectively, the angle that each bridge forms with the X axis as viewed from the electron gun is determined in relation to the incident angle of the electron beam impinging upon the bridge, in accordance with the distance of the bridge from the X and Y axes.
摘要:
A method for making a phosphor screen of a black matrix type color picture tube wherein use is made of two light sources, one being placed inside the faceplate of the tube and the other placed outside the faceplate, for carrying out a light exposure operation. An apparatus useful for such light exposure operation is also disclosed.
