Appeal No. 97-0124
Application No. 08/273,672
The disclosed invention relates to a cathode ray tube having
an electron gun which includes a pair of spaced apart electrodes
which are secured to insulating support members by connecting
elements. More particularly, Appellant indicates at pages 3 and
4 of the specification that, by varying the widths of the
connecting elements of adjacent electrodes, the “hopping” of
electrons between electrodes can be reduced or eliminated.
Claim 1 is illustrative of the invention and reads as
follows:
1. A cathode ray tube comprising: a display screen and an
electron gun having a means a for generating electrons, a number
of electrodes and a support means which is composed of an
insulating material, said electrodes being provided with
respective connecting elements which are secured in the support
means, wherein the electron gun comprises a pair of electrodes
which are arranged one behind the other, said electrodes which
are arranged one behind the other, said electrodes having the
connecting elements extending in a plane transverse to the
electron beam, and wherein the width of said connecting elements
of one of the electrodes of the pair of electrodes differs from
the width of the connecting elements of the other electrode of
the pair of electrodes.
The Examiner relies on the following reference:

Claims 4-9 stand finally rejected under 35 U.S.C.
§ 112, first paragraph, as being based on an inadequate
disclosure. Claims 1, 4, and 7-10 stand finally rejected under
35 U.S.C. § 102(b) as being anticipated by Guzowski. Claims 2,
