Abstract:
A vacuum envelope of a cathode ray tube comprises a faceplate and a rear envelope bonded to the faceplate. The rear envelope includes a rear plate opposed to the faceplate, a side wall, a plurality of funnels extending from the rear plate, partition walls set up on the rear plate, and necks bonded individually to the funnels. The rear envelope is formed by connecting a plurality of miniature envelopes to one another. Each miniature envelope includes at least one funnel, and is molded by pressing.
Abstract:
A glass panel for an implosion-protected type cathode ray tube is provided with a compressive stress of 7 MPa-30 MPa in an outer surface of a face portion and a relation of Rb≧0.017D+4.0 between the radius of curvature Rb of an outer surface of a blend R portion 9 in a diagonal portion of the glass panel and the largest outer diameter D of the glass panel Further, when the face portion is substantially flat, there is a relation of Tr≦0.014D+11.0 wherein Tr is the largest wall thickness of the blend R portion.
Abstract:
A cathode ray tube includes a panel having a substantially flat outer surface and an inner curved surface with a phosphor screen. The panel has a substantially rectangular effective screen portion with two long sides parallel to each other, two short sides parallel to each other and four rounded edges interconnecting each long side and the neighboring short side. The effective screen portion is structured such that a first line V1 interconnecting centers of the long sides, a second line H1 interconnecting centers of the short sides and a third line D1 interconnecting centers of the rounded edges opposite to each other meet at a point. The effective screen portion has a first thickness Tv at the centers of the long sides, a second thickness Th at the centers of the short sides, a third thickness Td at the centers of the edges and a fourth thickness Tc at the meeting point of the first to third lines V1, H1 and D1. A shadow mask is disposed within the panel such that the shadow mask faces the inner curved surface of the panel. The shadow mask has a curvature corresponding to the inner curved surface of the panel. The ratio of the second thickness Th to the third thickness Td while subtracting the fourth thickness Tc from each thickness satisfies the following condition: 0.75≦(Th−Tc)/(Td−Tc)≦0.85, and the ratio of the first thickness Tv to the third thickness Td while subtracting the fourth thickness Tc from each thickness satisfies the following condition: 0.75≦(Tv−Tc)/(Td−Tc)≦0.85.
Abstract:
A vacuum electron device comprises an evacuated envelope containing a cathode for supplying electrons to form an electron beam, an anode spaced from the cathode for receiving the electron beam, and a sensor electrode located between the cathode and the anode.
Abstract:
A glass funnel for a cathode ray tube capable of increasing the rigidity of a body portion having a rectangular-shaped open end portion and reducing the weight of the glass funnel wherein on at least a long side of the body portion, arched face portions are formed so as to be substantially perpendicular to an open end face of the body portion and an arch-like ridge portion in each of the arched face portions is extended to portions in the vicinity of the open end portion, whereby stresses generated in the body portion can be transmitted to the corner portions of high rigidity of the open end portion along the ridge portions.
Abstract:
A glass bulb for a cathode ray tube includes a panel and a funnel sealed to each other at respective seal edge portions to form a sealing portion. The panel includes a face portion with a substantially rectangular screen, and a skirt portion constituting a sidewall of the face portion and having a seal edge portion at its end. The funnel is connected to a cylindrical neck portion for housing an electron gun. A distance H from the center of the inner surface of the face portion to a point where a reference line of the funnel crosses the bulb's central axis, and the diagonal length D of the screen, satisfy D/H≧3.3. A bent portion bending towards the bulb's central axis is provided at least on a long side of the sealing portion.
Abstract:
A light-absorptive antireflection film comprising a light-absorptive film formed on a glass substrate containing pigment microparticles and having a physical thickness of not less than 10 nm and an antireflection multilayer film attenuating reflected light of incident light by interference of light, wherein at least one layer of the antireflection multilayer film is an electroconductive thin film having a surface resistance of not more than 1000 &OHgr;/□, and a display device including the same and methods of producing them.
Abstract:
A funnel-and-neck sealing body comprises a funnel having a substantially rectangular large opening to which a panel for projection tube is sealed, and a circular small opening; and a neck tube of substantially a cylindrical shape sealed to the small opening of the funnel. The neck tube has an electron gun installing region for installing an electron gun therein, and a yoke mounting region for mounting a deflection yoke externally thereon, wherein an outer diameter of the yoke mounting region is smaller than an outer diameter of the electron gun installing region.
Abstract:
A glass panel for a cathode ray tube comprises a substantially rectangular face portion on which images are displayed and a skirt portion continuous to the face portion through a blend R portion. An effective screen size of the face portion in a diagonal direction is 500 mm or more, an average radius of curvature of an outer surface of the face portion is 10000 mm or more in all radial directions from a face center portion, and a difference in height between the face center portion and an edge portion of the effective screen in the diagonal direction on an inner surface of the face portion is in a range from 9 mm to 17 mm.
