Appeal No. 96-1301
Application 08/175,078
disclosed as generally disk shaped has two faces (see
abstract, lines 5-8). Magnets are disposed around the
periphery of the two faces (see Figs. 2 and 3, column 4, lines
49-51). The polarities of the magnets on the respective faces
are alternating in polarity (see column 4, lines 17-21 and
column 6, lines 56-60). Furthermore, the polarities of the
magnets on the first face are opposite those of the
corresponding magnets on the second face, such that the
direction of polarization for each is the same.
For example, claim 1 of Hawsey recites a first set of
magnets positioned on one face of the rotor and a second set
of magnets positioned on the other face of the rotor (see
claim 1, lines 14-28). Claim 4 of Hawsey further recites that
the first set of magnets on the first face are oriented to
provide alternating polarities and that the second set of
magnets on the second face are oriented to provide alternating
polarities (see claim 4, lines 55-60). Claim 4 of Hawsey also
provides that the polarities of the second set of magnets are
opposite the polarities of the first set of magnets across the
central layer of the rotor (see claim 4, lines 61-63),
indicating that the polar orientation of the magnets is co-
directional.
