the conductor is bent. . .”(Column 2, lines 39-42).
Leef describes metal tapes for use in coaxial cables. Those
tapes may be obtained in several described ways including
deposition by evaporative techniques, chemical vapor deposition,
and electrophoretic coating. (Leef, page 4, last 5 lines).
It would have been obvious to spirally wrap the conductive
core of JP ‘321 with an insulator because spirally wrapped
insulators were commonly known in electric equipment and provided
additional flexibility as taught by Townsend. It would also have
been obvious to utilize metallized tapes formed by deposition as
described by Leef in place of the laminated tape of JP 321 in
order to obtain a desired thickness and uniformity and “highly
adherent thin metallic” coatings capable of mass production (Leef,
page 4, lines 10-12 and 32-36).
As to claim 7, we observe that it depends from claim 1, which
recites “. . . an insulation layer wound around said conductor . .
. ” Claim 7 (a newly added claim), on the other hand, recites
that “. . . said insulation layer is formed on said conductor.”
JP ‘622 describes prior art wrapped insulators in direct
contact with the conductor and the problems with them. See the
English language translation of record, page 2, lines 8-12, as
follows:
