does not teach or suggest brazing a ceramic feedthrough plate
directly to a vacuum package enclosure, where the feedthrough
has several holes with pins brazed in the holes. We find that
Mizuhara teaches that metal pins can be brazed to ceramic
substrate. See column 2, lines 38 through 46. Mizuhara
teaches that feedthroughs are used to provide conductive paths
through ceramic articles, and specifically cites a magnetic
inductive field flow meter where the feedthrough goes through
a ceramic cylinder. See column 1, lines 12 through 20. We
agree with the Appellants' statement on page 5 of the brief
that Mizuhara does not teach an enclosure of brazing the
feedthrough plate to the enclosure.
We find that Oeschger neither teaches brazing the ceramic
feedthrough to the vessel nor that the vessel is a vacuum
package enclosure. We find that Oeschger teaches a
feedthrough connector with a pin (item 13) going through a
ceramic feedthrough (item 14). We find that Oeschger teaches
that the brazing is done in one step. Specifically, Oeschger
teaches that the device is assembled such that the brazing
material (items 20, 22 and 23) which hold the ceramic
feedthrough (item 14) to body (item 17) and the brazing
