Abstract
1,234,513. Colour television tubes. SONY CORP. 8 April, 1969 [14 April. 1968], No. 17755/69. Heading H1D. In a colour television tube of the type wherein three co-planar electron beams follow divergent paths through a common focusing lens (of which part of the last electrode G5 is shown in Fig. 3) and are converged on the apertures of a grid or shadow mask by means of two pairs of deflection plates PP<SP>1</SP> and QQ<SP>1</SP>, the outer plates Q and Q<SP>1</SP> are supported by insulating members 25 of glass or -the like which extend across -and -are secured to the outer surfaces of the plates, the members 25 being supported by conductive pins 24 which extend through notches in the sides of the plates Q to the plates P. In this way the deflection space is shielded from any electric field produced by charges on the insulation 25, and further shielding is provided by-flaring the ends of the plate Q as shown in Fig. 3. The inner plates P may be provided with tabs .23 which are welded to a flange 53 on electrode G5 which is supported from the envelope by two discs, of which one 31 is shown in Fig. 3. Spring contact elements (27, Fig. 2, not shown) extend from the flange 53 to a wall coating to supply the-required voltage to electrode G5 and the inner plates P. The outer plates Q are'connected together by a lead 40, and a lead 36 extends to a button on the envelope to supply the required potential.
