Appeal No. 2005-0189 Page 2
Application No. 09/683,997
(specification, pages 2 and 3). The coils of the series circuits
are wound in alternating direction (specification, page 6) to
prevent or reduce a circulating current from flowing in the
parallel circuit (specification, pages 2 and 8). An
understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced as follows:
1. A permanent magnet type three-phase AC rotary electric
machine including a permanent magnet element having a number of
permanent magnet poles and a coil winding element having a number
of slots, each of said three phases being connected in a line
current circuit and being comprised of a parallel circuit formed
by connecting a plurality of series circuits in parallel, said
coil winding element comprising cores of each of said series
circuits combined such that electromotive voltages or counter
electromotive voltages generated across opposite ends of said
plurality of series circuit forming each phase are substantially
the same based on symmetry of arrangement of said permanent
magnets and said coils, thereby preventing generation of a
circulating current in said parallel circuit.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Kilgore 2,575,716 Nov. 20, 1951
Nishio et al. (Nishio) 5,006,745 Apr. 9, 1991
Naoki et al. (Naoki) JP2001-197696 Jul. 19, 2001
Claims 1-4, and 7-9 stand rejected under 35 U.S.C. § 103(a)
as being unpatentable over Naoki in view of Nishio.
Claims 4 and 6 stand rejected under 35 U.S.C. § 103(a) as
being unpatentable over Naoki in view of Nishio and Kilgore.
