Appeal No. 1996-1568
Application No. 08/235,235
APPENDIX
1. A process for producing a resistive element,
comprising:
(A) forming a substrate glazed with glass;
(B) printing or coating a resistive element-forming
paste onto said substrate glazed with glass;
(C) calcining the paste in a first heating step by
maintaining said paste at a first temperature level to
decompose and eliminate organic substances in the coated paste
without interaction between the coated paste and the glass to
form an element comprising a film on said substrate glazed
with glass; and
(D) subjecting the resulting element to a heat treatment
in a second heating step at a second temperature higher than
said first temperature level to diffuse an amount of the glass
into said film to increase resistivity of said element.
28. A process as claimed in claim 1, wherein conditions
of said heat treatment are selected to control resistivity of
said element.
