    Abstract: In a shadow mask support means comprising a bi-metal piece having one end secured to a shadow mask frame with the other end left free, and a leaf spring secured at one end to said free end of the bi-metal piece and extending therefrom toward a pin provided on a side wall of a face panel, the improvement residing in that a metallic plate portion disposed between said frame and said spring is so arranged that it is displaced due to thermal deflection of the bi-metal at the end adjacent to said pin by an amount smaller than the displacement at the opposite end.

    Abstract: A shadow mask support means including three leaf springs for supporting a rectangular shadow mask on a face panel at three sides of a frame of the mask, said three leaf springs having a predetermined relationship with respect to the spring constant and deflection so that, even when the image tube is subjected to a shock load or the shadow mask in thermally expanded, the change in the relative position of the shadow mask and the face panel is minimized.

    Abstract: 1278360 Colour television tubes MATSUSHITA ELECTRONICS CORP 24 March 1970 [24 March 1969] 14054/70 Heading H1D A rectangular shadow mask is supported by means of three spring supports of which the top one 10 has a spring constant 50-60% of that of the other two 20 and 30 and a smaller spring deflection so that the resultant of the three forces 14, 24, 34 produced by the springs is substantially reduced. The spring deflection is defined as the displacement of the end of the spring towards the mask, and that of the support 10 may be 0À42-0À5 of that of the other two supports. Preferably the supports 20 and 30 are disposed so that the line X 11 -X 11 intersects the spring portions 23 and 33, this line being spaced below the centre line X-X by a quarter of the height of the frame. In a 20 11 tube the line X 1 -X 1 joining the pins 21, 31 may be disposed 54 mm. below the line X-X.
