PRESSURIZING JIG USED IN MANUFACTURING COLOR SELECTING ELECTRODE OF COLOR CRT, AND MANUFACTURE OF COLOR SELECTING ELECTRODE OF COLOR CRT

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of wrinkles on an electrode element assembly by using a pressurizing jig having a fixed projection provided on a prescribed face of a block in contact with the vicinity of the center section of one of the upper and lower members, to which many electrode element assemblies are fixed, of the frame of a color selecting electrode and an oscillating projection having a planer contact face provided on the prescribed face of the block is contact with the vicinity of the center section of one of the upper and lower members. ;SOLUTION: This pressurizing jig 20 is provided with an extremely small-diameter semicylindrical projection 22 extended in the nearly perpendicular direction to the long side from one long side to this side of the other long side near one end section on one side face of a nearly rectangular solid-shaped block 21. The pressurizing jig 20 is also provided with an oscillating projection 23 having a planar contact face 23a in contact with one of the upper and lower members of a frame near the other end section on one side face of the block 21. A recess 24 is provided at the other end section of the block 21, and the oscillating projection 23 is inserted into the recess 24 so that a part of the contact face 23a side is exposed. When two pressurizing jigs 20 are used to pressurize the frame, the applied force to the vicinities of both end sections of the upper and lower members is distributed.;COPYRIGHT: (C)1998,JPO
