Application 07/891,852
efficient conductor of heat. Appellant does agree that Graham
does not require resinous
cement but Graham's only teachings is a cement which is more
of a heat insulator than a heat conductor.
Turning to Appellant's claim 10, we fail to find
that the scope of the claim requires a heat conductor cement
as argued by Appellant. Appellant's claim 10 recites "an
electrically conductive coil attached to said cylindrical
portion of said diaphragm, said coil transmits to said
diaphragm heat generated by an acoustical current passing
through said coil to quickly and efficiently dissipate heat
generated by said coil through said metal diaphragm to said
metal support unit." Appellant's
claim 10 does not require an attachment means that transmit
heat to the diaphragm. Appellant's claim 10 only requires
that the coil transmit heat to the metal diaphragm.
Sotome '124 and Graham teach a coil made of
conductive material that would transfer heat quickly and
