Appeal No. 1996-1568
Application No. 08/235,235
This is a decision on an appeal from the final rejection
of claims 1 through 5, 21 through 23 and 25 through 28 which
are all of the claims pending in the application.
The subject matter on appeal relates to a process for
producing a resistive element which comprises coating a glass-
glazed substrate with a resistive element-forming paste and
calcining the paste in a first heating step at a first
temperature level to form an element comprising a film on the
substrate and subjecting the resulting element to a heat
treatment in a second heating step at a second temperature
higher than the first temperature level to diffuse an amount
of the glass into the film to increase resistivity of the
element. This appealed subject matter is adequately
illustrated by independent claim 1 and dependent claim 28,
copies of which taken from the appellants’ Brief are appended
to this decision.
The references relied upon by the examiner as evidence of
obviousness are:
