Appeal No. 1997-1181 Page 2
Application No. 08/000,735
BACKGROUND
The appellants’ invention relates to a method of
manufacturing electrical windings used for rotating electric
machinery for rail and road vehicles, etc., and, more
particularly, to an electrical winding manufacturing method
which can be effectively applied to the manufacture of various
types of electrical windings including wires differing in
shape, size and function while enabling the respective
windings to perform the required functions (specification,
page 1). Claim 1, the only independent claim involved in this
appeal, reads as follows:
1. A method of manufacturing electrical windings
differing in function comprising the step of forming
windings by winding conductors, the step of applying
insulation on each of said windings, the step of
embedding each of the windings covered with the
insulating layers in a core, the insulating layers
suitable for each of the respective types of
windings being formed in said step of applying
insulation, the step of impregnating a same resin in
all of the respective windings and a single step of
hardening the impregnated same resin in all of the
insulated windings to set the windings embedded in a
core.
The examiner relied upon the following prior art
reference of record in rejecting the appealed claims:
