Application No. 08/445,926
As to the second element discussed by appellants,
involving the zero draft geometries, we agree that Moon
includes no such disclosure. However, the examiner has relied
upon the teachings of Roddy for the reason why the skilled
artisan would have modified Moon to meet the claim limitation.
Specifically, Roddy teaches (column 1, lines 63-66)
"eliminat[ing] the need for a machined opening in a die cast
bearing support structure by providing an opening in the
bearing support structure effectively having zero draft."
Further, Roddy states (column 2, lines 3-4) that an object of
the invention is to lower the cost of a bearing support
structure. In addition, Roddy suggests (column 1, lines 11-
13) that the invention applies to other die cast press fit
structures. Since Moon uses metal castings, in view of the
combined teachings of Moon and Roddy, one of ordinary skill in
the art would have found it obvious to utilize Roddy's zero
draft geometries with Moon's metal castings for mounting the
spindle motor shaft and actuator bearing shaft to eliminate
the need for a machined opening and reduce the cost.
Lastly, regarding the integral diffusion path and
channel, although we disagree with the examiner's first line
