Abstract
1513809 Cathode ray display tubes SONY CORP 4 Dec 1975 [17 Dec 1974; 28 April 1975] 49870/75 Heading H1D A c.r.t. comprises a conductive reinforcing band 21, transparent protective panel 14, transparent conductive, adhesive resin material 15, and at least one conductive connecting element 20 providing connection between the material 15 and band 21 so that the conductive resin can be connected to a reference potential such as ground. The arrangement counters the probability of shock by a receiver on contacting the panel. Flexible insulating tape 18 (e.g. 0À5 mm's thick polyester) prevents resin leakage and is pierced by pointed contact piece(s) 20B. Each member 20 is positioned after the resin has been injected and may include a further portion 20A (also Fig. 3, not shown) to define a U-shaped clip for panel 14. The various portions of member(s) 20 may be formed integrally or positions 20A, 20B may be resilient for gripping panel 14, and portion 19 flexible to conform to band 21 contours. Alternative forms of connecting members are detailed (Figs. 4A, B and 6, not shown). There may for example, be one of the latter at each corner with bores 23 for mounting. Conductive resin and panel materials are exemplified.
