page 5) that Chuta discloses more than one region where the hub
is bonded to the outer races. In addition, we agree with
appellants (reply brief, page 1) that as shown in figures 3 and 4
of Chuta, the only surfaces of the outer races which are
contiguous to hub body 126 are located above and below the ball
bearings, forming more than one bonding surface, and that the
bonding region is not located axially between the two ball
bearings. We do not agree with the examiner that the contact
between hub 104 and spacer 125 can reasonably be construed as a
plurality of contact regions. The plurality of contact regions
are the portions of the hub 104 which contact the outer races at
locations above and below the ball bearings, as shown in figures
3 and 4 of Chuta.
In addition, we find that one of ordinary skill in the art
would not have been motivated to combine the teachings of Chuta
with the teachings of figure 2 of AAPA, as advanced by the
examiner. In Chuta, (col. 1, lines 60-64) an object of the
invention is to prevent the outer bearing member from being
deformed when fixing the hub member, or as a result of
temperature changes after assembly of the spindle motor. Chuta
teaches (col. 2, lines 9-13) that the hub member is fixed to the
outer bearing member by press fitting or shrinkage fitting, and
