Appeal No. 97-2546
Application 08/399,722
from Figures 1 and 4 that the core member (10) of Takayanagi
includes an annular positioning protuberance (17) thereon for
abutting against the end wall (18) of the sleeve part (4) when
the core and sleeve are assembled together, we see no annular
groove on the sleeve which is complementary to said
protuberance.
The examiner’s position (answer, page 6) that the element
(8) shown in Figure 1 of Takayanagi is part of the sleeve and
“has an annular groove which is complementary to the annular
protuberance 17,” in our opinion, is based on total
speculation and conjecture. Even if we were to agree with the
examiner that the fixing tape (8) wrapped about the sleeve
part (4) and the adjacent portion of the core (10) at the
right side of Figure 1 of Takayanagi could be considered to be
part of the sleeve, there is no reasonable basis to conclude
that the inner surface of the “sleeve” (tape 8) necessarily
includes an annular groove that is complementary to the
protuberance (17) on the core (10). The wrapping of the tape
(8) in the vicinity of the protuberance (17) could just as
easily bridge the space from the edge (at wall 18) of the
