摘要:
An assembly of at least two detachably superposed anti-implosion bands 14, 24. Each anti-implosion band 14, 24 comprises suspension elements 15, 25 projecting from the anti-implosion band 14, 24. The suspension elements 25 of the anti-implosion band 24 surround the anti-implosion band 14 with clearance. As a result hereof, anti-implosion bands can be stacked in a simple manner to form an assembly, and the anti-implosion bands can be detached in a simple manner.

A cathode ray tube for use as a video display or the like comprises a panel, a funnel, and a stress resistant frame having an L-shaped bend and constituted by a metal frame joined to both the panel and the funnel. The stress resistant frame is adapted to reinforce the cathode ray tube against a tensile stress occurring due to a reduction in the internal pressure of the cathode ray tube.

A cathode ray tube subjected to an antistatic treatment and a method of making the same. A conductive surface of a panel (2) of a bulb body (7) is grounded through a metal reinforcement (4) serving as a reinforcement for maintaining the bulb's inward bursting resisting properties to instantaneously leaking any electrified charge, thereby providing the antistatic cathode ray tube which is free from the effect of air-conditioned humidities. Thus, there is the effect of preventing the occurrence of erroneous operations of the cathode ray tube and peripheral units and adverse effects on the human body, e.g., electric shock due to the charged static electricity on the panel surface (2), and there is another effect that the implosion protective adhesive glass tape (5) or the member interposed between the conductive coating (1) and the metal reinforcement (4) is equivalent to lead wires thus eliminating the use of lead wires and thereby eliminating the provisions of complicated connections to the panel surface (2).
摘要:
A resin bonding system (14) which bonds a substantially flat implosion protection panel (12) to the nominally flat faceplate (10) of a flat tension mask CRT tube and is cured by exposure to ultraviolet radiation. The resin bonding system is designed for differential adhesion so that the faceplate separates more easily from the resin than does the implosion protection panel, thus achieving superior implosion performance. It also incorporates a contrast-enhancing neutral density agent, preferably confined to a flat layer adjacent to and adhered to the flat surface of the implosion panel in order to achieve uniform neutral density filtration across the face of the tube. The neutral density agent is preferably an organic dye. Because the nominally flat faceplate is actually somewhat concave after evacuation of the tube, confining the neutral density agent to the layer which adheres to the flat faceplate avoids mottling of the CRT picture which would otherwise result from changes in the thickness of the pigmented layer across the face of the CRT.

A composite mounting structure for a cathode ray tube is described wherein L-shaped mounting brackets 23 are secured along the corner regions of the peripheral skirt 19a of the cathode ray tube face panel 15 by a steel tension band, and wherein slippage of the brackets 23 and tension band 21 during severe thermal or mechanical shock is minimized by the inclusion of slip-resistant foam mounting blocks 30 between the base portions 29 of the mounting brackets 23 and the glass skirt portion 19a of the face panel 15.
摘要:
Bei Bildröhren werden wenige scharf begrenzte und unregelmäßig verteilte Hindernisse als Inhomogenitäten im oder am konischen Teil der Kolbenwandung angebracht. Damit wird der Ablauf einer unvermeidbaren Implosion schon von Beginn an beeinflußt, indem an den Inhomogeni täten infolge der Energieanreicherung beim Auftreffen von die Röhre gefährdenden Stößen Rißbildung ausgelöst wird. Diese Risse pflanzen sich sofort bis zum Röhrenhals fort und führen dort zu einer gefahrlosen Belüftung der Röhre.
摘要:
A cathode-ray tube comprising an envelope including a glass faceplate panel (27) and an adjoining glass funnel (25) sealed to the panel, is provided with protection against the effects of implosion by means of an elastomeric coating (39) of polyurethane disposed around and adhered to external surfaces of the envelope. This mode of implosion protection is easier and cheaper to manufacture, especially in mass production, than is the prior art provision of an encircling rigid coating of plastic-impregnated fiber or fabric. The coating (39) is preferably produced by applying, drying and curing a coating of an aqueous emulsion of polyurethane on the desired external surfaces of the tube. The coating may extend from the panel (27) as far back on the adjoining funnel (25) as desired, and as far forward on the panel sidewall (29) and over the viewing window as desired. The polyurethane coating (39) may be used in combination with a metal tension band.

The present invention provides a flat-panel display member comprising a barrier rib on a glass substrate, wherein the barrier rib contains a low softening point glass as a main component, the barrier rib contains a low softening point glass and the barrier rib is composed of at least two layers, and also a low softening point glass, which is a main component of the uppermost layer of the barrier rib, has an elastic modulus of 80 GPa or less. According to the present invention, the destruction of the barrier rib, which may cause non-lighting or abnormal lighting of discharge cells, has been suppressed.
