Appeal No. 1997-3148
Application 08/408,088
On pages 3 through 5 of the specification, Appel-
lants disclose that they solve this problem by providing a
high- resistance resistor 17 placed between the junction point
16 and
the terminal 14 as shown in figure 2. Appellants disclose on
page 5 of the specification that the resistance is of approxi-
mately 100K Ohms and that this prevents destructive breakdown
of the insulating layer.
Independent claim 16 is reproduced as follows:
16. A cathode ray tube comprising a display window,
grids and at least one semiconductor cathode for generating an
electron beam, a main surface of a semiconductor body of said
cathode being provided with an electrically insulting [sic,
insulating] layer having at least one aperture at the location
of an electron-emitting area, at least one gate or accelerator
electrode being present on the electrically insulating layer,
characterized in that the at least one gate or accelerator
electrode is connected to a terminal via a relatively high-
resistive resistor and that at least one semiconductor cathode
and the relatively high-resistive resistor are present on a
common support.
The references relied on by the Examiner are as
