Appeal No. 96-1301
Application 08/175,078
opposite sides of the central member are oriented so that
their magnetic fields are opposed.” (Brief, at 8).
Our reading of the Hawsey disclosure does not reveal that
its magnet pieces are positioned as the appellants say they
are as is shown in appellants’ Fig. 3b. Instead, as is
indicated in the claim language of the Hawsey patent (i.e.
claims 4, 13 and 18) the second set of magnets are oriented
such that the polarities of the second set of magnet pieces
are opposite the polarities of the first set of magnet pieces
across the central member, as is the case with the appellants’
claimed invention shown in Fig. 3a. The magnetic lines of
force in Hawsey do not cross the central member, because in
Hawsey, the rotor’s central member includes an isolator to
isolate the magnet pieces on the opposite faces from each
other. See Hawsey in column 3, lines 2-4. That is not
excluded by the appellants’ claim 1.
Appellants’ claims 1-5, 7-15, 17-19, 21 and 22 stand
finally rejected as being anticipated by Takahashi. Takahashi
teaches a central member 9 of a rotor with magnets 1 secured
to the central member, as shown in Fig. 8. The examiner
states that Takahashi teaches “a 2 m field magnet consisting
of north and south poles alternately positioned”. But this
