Application 10/286,535
The issues before us are:
1. Whether Appellants have shown that the Examiner erred in rejecting
claims 1, 3-5, 7, 10-27, 42, and 43 as unpatentable over Sakayanagi and
McGaffigan.
2. Whether Appellants have shown that the Examiner erred in rejecting
claims 6 and 36-41 as unpatentable over Sakayanagi, McGaffigan, and Bleske.
FINDINGS OF FACT
We find that the following enumerated findings are supported by at least a
preponderance of the evidence. Ethicon, Inc. v. Quigg, 849 F.2d 1422, 1427,
7 USPQ2d 1152, 1156 (Fed. Cir. 1988) (explaining the general evidentiary
standard for proceedings before the Office).
1. Sakayanagi discloses a method for manufacturing armatures having a
cylindrical core with multiple slots in the outer periphery and a commutator
connected to coils wrapped around the slots in the outer periphery of the core, the
coils having coating layers consisting of a fine inorganic powder on their surfaces.
The method includes, inter alia, using a high-frequency induction heating
apparatus to turn the coating layers on the coils into ceramic by heating up the core
by means of the Joule heat (Sakayanagi 5).
2. The high-frequency induction heating device is provided with high-
frequency coils 51 and a high-frequency power source 52 (Sakayanagi 9 and
Fig. 1).
