enclosure." On pages 2 and 3 of the answer, the Examiner
states that Oeschger "teaches using a ceramic feedthrough
block (14), having a pin brazed therein (Column 5, lines 48-
53), in a wall (17) of an enclosure (Column 1, lines
7-10) wherein the ceramic feedthrough block is brazed (Column
5, lines 63-68) to a metal member sealed to the wall using
brazing." The Examiner also asserts on page 3 of the answer
that Oeschger teaches simultaneously brazing a ceramic member
to a metal member and a metal pin to the ceramic member. The
Examiner asserts on page 9 of the answer that:
Oeschger et al states that the brazing techniques
used are "well known in the vacuum capacitor and
interrupter arts." It would be obvious to use
teachings of Oeschger et al for any type of
electrical package, and since Oeschger et al
specifically states the brazing techniques are known
for vacuum components, it would be obvious to use
them for a vacuum package.
Finally, on page 9 of the answer, the Examiner asserts that
brazing the ceramic directly to the metal wall "would have
been obvious to one of ordinary skill in the art at the time
the invention was made since it is already brazed to a metal
member" and the prior art of record in the case supports this
assertion.
