Abstract: A cathode ray tube having an evacuated envelope including a substantially rectangular faceplate panel with a sidewall joined to a funnel and an implosion resistant band surrounding at least a portion of the sidewall and in contact therewith. The cathode ray tube is mounted in a cabinet by a plurality of mounting lugs. The mounting lugs having a base portion attached to the implosion resistant band, an adjoining portion substantially perpendicular to the base portion, and a mounting portion positioned at an angle in respect to the adjoining portion. The mounting portion having an aperture for receiving a fastner for coupling the mounting portion to the cabinet.

Abstract: The present invention provides an implosion prevention tension band 16 for use in a cathode ray tube (CRT) 10. The CRT includes a faceplate panel 18 with a substantially flat viewing faceplate 21 and a peripheral rearwardly extending sidewall 22 having an inside blend radius 23 from the viewing faceplate 21 to the sidewall 22. The tension band 16 is a single layer band surrounding the panel 18 and having a predetermined width extending rearwardly from near the faceplate 21 to at least half the distance between the rear edge of the inside blend radius 23 and the rear edge of the sidewall 22. According to another aspect of the present invention, the tension band 16 includes a plurality of tension adjusting features 40 being positioned at locations around the band 16 aft of the inside blend radius 23 in such manner that the stresses in predetermined areas of the panel 18 are reduced.

Abstract: The present invention provides an improvement in the mounting of a cathode-ray tube within a bezel. The cathode-ray tube includes a unitary shellbond frame having integral mounting lugs which are positioned at locations either in the corners or off of the corners. The mounting lugs are formed with tapered sections along a depth dimension to allow a tube having the shellbond frame applied to be simply lowered into a bezel having lug receiving recesses of a complimentary shape. The tapered lug and complimentary lug receiving recess provides self-alignment of the tube before it is secured to the bezel.

Abstract: The present invention relates to an implosion prevention band for a CRT comprising an evacuated envelope having a mask and corresponding faceplate panel with sidewalls joined to a funnel. The faceplate panel and sidewalls form external corner surfaces and a peripheral inside blend radius. An implosion prevention band surrounds and closely hugs at least an edge of the external corner surfaces of the faceplate panel. The band extends along the exterior surface of the sidewall such that the width of the band is at or near the inside blend radius of the faceplate panel. The band is under tension to produce radially inwardly directed force components through the corners of the faceplate panel and primarily near the blend radius to produce a high degree of implosion protection for the CRT.

Abstract: A display apparatus 10 comprises at least one speaker 16 and a cathode-ray tube (CRT) 14 secured within an enclosure 12 to a plurality of mounting bosses 50. The cathode-ray tube 14 has an evacuated envelope 17 with a substantially rectangular-shaped faceplate panel 18 having four corners and a viewing portion 26 extending to a peripheral sidewall 28. The viewing portion 26 has a luminescent line screen 32 on the interior surface thereof The viewing portion 26 including two orthogonal axes, a major axis, X, parallel to a longer dimension of the viewing portion and a minor axis, Y, parallel to a smaller dimension of the viewing portion. The CRT 14 has therein an electron gun 38, capable of generating at least one electron beam, aligned along a central longitudinal axis, Z, of the CRT that is perpendicular to the major and minor axes. The CRT 14 also has a color selection electrode 36 in proximity to the interior surface of the viewing portion 26 of the faceplate panel 18.
