Abstract
Abstract 11. A CIRCUIT BOARD COMPRISING A DIELECTRIC SUBSTRATE OF YTTRIUM IRON GARNET HAVING AN AUTOGENEOUSLY FORMED CONDUCTIVE PORTION DEFINING A CONDUCTIVE PATH THEREON, SAID CONDUCTIVE PORTION COMPRISING A PART THAT HAS A COMPARATIVELY HIGH CONDUCTIVITY AND A PART CONTIGUOUS WITH SAID COMPARATIVELY CONDUCTIVE PART THAT IS LESS CONDUCTIVE, WHEREBY SAID LATTER PART EFFECTIVELY DEFINES A RESISTOR ON SAID CONDUCTIVE PATH.
