Application 08/246,140
DECISION ON APPEAL
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-3.
We reverse.
BACKGROUND
The invention is directed to a fixing spring which is
used for securing a color-selecting electrode within a
cathode-ray tube display. In particular, Appellants claim a
fixing spring having a shape factor K determined by the
dimensions of the spring and the weight of the color-
selecting electrode.
Claim 1 is reproduced below.
1. A cathode-ray tube having a color-selecting
electrode which is secured to a fluorescent glass panel
with a plurality of fixing springs between said
color-selecting electrode and a corresponding plurality
of fixing pins on said fluorescent glass panel, wherein
said fixing springs have a shape factor K in a range of
3 3
from 10 mm /kg to 100 mm /kg, wherein the shape factor K
is determined by the following equation:
K=(a thickness of the fixing spring)x(a breadth of
the fixing spring) x(a height of the fixing spring)/(the2
length of the fixing spring)/(a weight of said
color-selecting electrode).
The examiner relies on the following prior art:
