disclosure of what arrangement of rectifier is used with the
annular arrangement of five phase windings. In this
situation, the rectifier may be less than five phases.
To determine whether claim 1 is anticipated, we must first
determine the scope of the claim. We note that representative
claim 1 reads in part as follows:
[S]aid armature winding is constructed by connecting
five winding phase portions into an annular shape such that
the electrical angular phases of electromotive force differ
from each other by approximately 72 degrees.
At page 8, paragraph 44, Appellants’ specification states
the following:
[0044] The stator 8 is provided with: a stator core 15;
and an armature winding 16 installed in the stator core 15.
This armature winding 16 is constructed into a five-phase
armature winding by connecting five winding phase portions
31a to 31e, including an a-phase winding phase portion 31a,
a b-phase winding phase portion 31b, a c-phase winding phase
portion 31c, a d-phase winding phase portion 31d, and an e-
phase winding phase portion 31e, into an annular shape (a
ring connection) so as to have a phase difference
corresponding to an electrical angle of 72 degrees from each
other. Connection portions between each pair of adjacent
winding phase portions are connected to respective
connection portions between a positive-side diode d1 and a
negative-side diode d2.
Thus, representative claim 1 does require an armature winding
being constructed by connecting five winding phase portions into
an annular shape to be rectified by a five phase full wave
rectifier.
Now, the question before us is what Buening would have
