Appeal No. 1997-1181 Page 5
Application No. 08/000,735
in Paper No. 22 that the method of the Japanese document
includes a step of embedding a plurality of conductor windings
in a core subsequent to separate steps of impregnating and
hardening insulating resin into the insulation-covered
conductor windings. According to the attachment included in
Paper No. 22, the step of embedding the plurality of windings
in a core appears to be a single hardening step. We perceive
this embedding step to include pouring the high viscosity
resin 8 between the windings and the core and hardening the
resin 8 to form a field device, as discussed above.
Even taking into account the above-noted concessions of
appellants, we find no teaching in the Japanese document to
perform a single step of hardening the impregnated resin in
all of the insulated windings (a plurality of windings
differing in function5) to set the windings embedded in a
core, as required in claim 1. Rather, in accordance with the
method of the Japanese document, each of the windings is
subjected to a separate impregnation and hardening step to
form a plurality of field windings 5 which are then embedded
5 Consistent with appellants’ underlying disclosure, we understand
“windings differing in function” to be windings having different properties,
such as size or shape so as to have different current-carrying and/or magnetic
properties.
