Title:
ASSEMBLY OF LIQUID COOLED TYPE CATHODE-RAY TUBE
Document Type and Number:
Japanese Patent JP3141250
Kind Code:
B2
Abstract:

PURPOSE: To improve the accuracy for assembly of a cathode-ray tube and for alignment of optical axes of the panel and a projection lens, by placing the front face of the panel of the cathode-ray tube on the tips of reference rods so as to position the front face of the panel and an end plane of a frame in parallel.
CONSTITUTION: When a frame 12 wherein cooling liquid is to be sealed is attached to the front face of the panel 9 of a cathoderay tube 1, the frame 12 is placed on a horizontal reference plane 32a of a jig 31 so as that one side end planes 17a, 18a of the frame 12 whereon a lens is to be arranged are contacted to the reference plane. Then the front face of the panel 9 is placed on the tips of reference rods 33 projecting vertically from the horizontal reference plane 32a so as to position the front face of the panel 9 of the tube 1 and the end planes 17a, 18a parallel to each other to attach the frame 12 to the front face of the panel 9. The frame 12 is attached to the front face of the panel 9 through an adhesive layer 44. Thereby the optical axis of the curved surface provided on the inner face of the panel 9 and the optical axis of a lens system attached to the frame 12 can be aligned in high accuracy to assemble the cathode-ray tube.
