摘要： PROBLEM TO BE SOLVED: To prevent a hillock when an Al cabling is used to lower resistance in the cabling in a display apparatus. SOLUTION: The Al cabling is made a multi-layer structure and an element which does not form a continuous solid solution with Al is added to each layer. Good elements are rare earth metals such as Nd, dystectic point transition metals such as Ta and noble metal compounds such as Pd. Intermetallics 55 of Al and these elements deposit on interface 151 of the multi-layer cabling and prevents the hillock from being formed by swelling of crystal grains of Al.

摘要： PROBLEM TO BE SOLVED: To cope with generation of sparks around through holes of a glass substrate, in an FED (field emission display).
SOLUTION: The inside of the FED needs to be exhausted in vacuum. Surrounding a venthole 10 formed at a cathode base plate 1, an exhaust room is formed with an exhaust base plate 6 and an exhaust base frame body 71, an exhaust base plate venthole 81 is formed at the exhaust base plate 6 to be connected to an exhaust tube 8, through which, the inside of the FED is exhausted into vacuum. If a sharp edge is formed at an end part of the venthole 10, sparks are generated with the edge as a starting point. As a countermeasure for this, chamfering 101 is formed against the venthole 10. It is more preferable if a chamfering is formed at the exhaust base plate venthole 81 and a high-voltage lead-in button hole 82. With this, sparks based on the end part of the through hole 10 or the like formed at the cathode base plate 1 or the like can be restrained.

摘要： PURPOSE:To make safe the color purifying adjustment work at a narrow and dangerous place, by installing adjusting jigs with the outer diameter layer than that of a ring-form color purifying magnet around conventional color purifying magnets, and operating with grips furnished at the jigs. CONSTITUTION:By engaging ring-form adjusting jigs 2 and 2' with gears 4 around color purifying magnets 1 and 1', the adjustment of the color purifying magnets 1 and 1' is carried out by moving the grips 3 and 3' of the jigs 2 and 2' in the directions of the arrows. Practically the adjustment is formed in the condition of connecting the jigs 2 and 2' together. In this case, by forming the adjusting jigs 2 and 2' not in a regular ring but with cutting ends 5 about at the opposite sides of the grips 3 and 3', the installation and the removal for the adjustment work can be easily done. Therefore, it is possible to use the jigs only when the adjustment is necessary.

摘要： PURPOSE:To prevent the deformation and distortion of a shadow mask by absorbing shock loads with longitudinal and lateral beads provided to surround a welded portion. CONSTITUTION:As longitudinal beads 7, 8 and lateral beads 9, 10 are provided to surround a welded portion 6, stresses do not concentrate on one point due to the presence of beads 7-10 serving as shock absorbing materials. Because the longitudinal beads 7, 8 absorb shock loads in the vertical direction, the skirt portion of the shadow mask has a light strength against buckling stresses. This prevents an effective surface from deforming and prevents the shadow mask 1 from displacing. Also, because the lateral beads 9, 10 absorb the lateral shock loads, the effective surface is prevented from deforming.

摘要： PURPOSE:To allow the correction or the comatic distortion by arranging specific circular arc-shaped flat plates on the periphery of outside electron passing holes. CONSTITUTION:A center electron beam passing hole 2g is arranged at the center of the inside bottom of a cylindrical shield cut 1, and outside electron beam passing holes 2r, 2b are arranged centering the hole 2g on a straight line outside it. Circular arc-shaped flat plates 3, 3 are arranged axially symmetrically on the inside bottom of the cup 1 around the holes 2r, 2b respectively. The flat plate 3 is made of a material of 78%Ni-22%Cr, for example, with the high relative permeability and a thickness of about 0.1-0.4mm and has 90 deg. notch sections outside the arranged positions respectively. Accordingly, the green raster, red raster, and blue raster nearly match, and the comatic distortion can be suppressed to the minimum.

摘要： PURPOSE:To make it possible to obtain good convergence only with a shield-cup by using a shield-cup of specified shape. CONSTITUTION:The cylindrical shield-cup of a cathode-ray tube has a mult-angular bottom plate 7 long in the transversal direction in which three electron beams are arranged and short in the longitudinal direction perpendicular to the transversal direction. And the three electron beams 7a-7c are arranged symmetrically to the plane of arrangement of the three beams 7a-7b including the both outer beams. The shield-cup is constructed so as to be surrounded with two side walls 6a, 6c consisting of plates parallel or slightly tilted to the said plane and long in the transversal direction respectively and two side walls 6c connected to the both ends of which nearly perpendicular to which and facing to each other symmetrically to the tube axis and short in the longitudinal direction. Thereby an eddy current is generated in the wide side walls in the vicinity of the passing through holes of the outer beams, thus the deflections of the both outer beams are delayed to nearly equalize the deflection velocities of the three electron beams 7a-7c. By using this shield-cup with a correction means consisting of a combination of respective two ring-shaped permanent magnetic plates or the like, good convergence can be obtained.
