Abstract
1,246,199. Colour television tubes. SONY CORP. 22 Dec., 1969 [28 Dec., 1968], No. 62493/69. Heading H1D. In a colour television tube of the shadow mask type, misregistration of the beams due to thermal expansion of the shadow mask is compensated by moving the centre of deflection of the beams by providing auxiliary deflection coils acting in opposition to the main deflection coils and wound on a core of material whose permeability decreases with temperature. The core may comprise a ring of 70% iron, 30% nickel alloy disposed to the rear of the main deflection yoke; when the screen comprises vertical stripes and the mask has strip-like apertures, compensation is necessary only in the horizontal deflection field and two coils in series are wound on the core (Fig. 3, not shown); when the screen is of the multi-dot type compensation is also necessary in the vertical deflection field, and a further pair of coils are wound on the core (Fig. 8, not shown). The coils are preferably connected in series with their respective main coils.
