Appeal No. 96-2276
Application 08/128,622
in Fig. 5a with a slit 41 located in at least one side of the
frame to which the mask is attached at points 42. (Spec., pg.
6, lines 26-29). The differences in thermal expansion between
the mask and the frame result in the slit 41 becoming narrower
or wider. (Spec., pg. 7, lines 1-5). The narrowing or
widening of the slit 41 results in bending of the frame.
(Spec., pg. 7, lines 5-6). The expanding or contracting and
hence bending of the frame is said to be accomplished without
deforming the shadow mask. (Spec., pg. 7, lines 5-7).
The second embodiment in the specification that describes
preventing deformations of the shadow mask is found on pages 8
and 9, with reference to Fig. 6. In this embodiment, in
addition to the slit located in at least one side of the
frame, a flexible connection 51 is located at the ends of the
side of the frame and connected to both the mask and the
frame. (Spec., pg. 9, lines 1-2). As in the other
embodiment, contracting, expanding, and bending of the frame
is said to be accomplished without deforming the shadow mask.
(Spec., pg. 9, lines 2-6).
In both embodiments, when the frame contracts, expands or
bends, the shadow mask is not further deformed. Nothing
disclosed in the specification purports to keep the shadow
