Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
97 words
AN ASSEMBLY OF DISCRETE FILM RESISTORS COMPRISING AN INSULATIVE SUBSTRATE HAVING A PLURALITY OF HOLES THEREIN, EACH HOLE CORRESPONDING TO ONE OF SAID FILM RESISTORS AND HAVING A THIN LAYER OF ANODIZED METAL OF A CLASS CONSISTING OF TITANIUM, ZIRCONIUM, AND HAFNIUM ON THE INNER SURFACE THEREOF FORMING A RESISTIVE FILM, AND A WIRING PATTERN FORMED ON AT LEAST ONE FACE OF SAID SUBSTRATE FOR ELECTRICALLY INTERCONNECTING THE RESISTIVE FILMS IN SAID HOLES IN A PREDETERMINED MANNER, THE RESISTIVITY OF THE RESISTIVE FILMS IN SAID HOLES BEING VERY MUCH GREATER THAN THE RESISTIVITY OF SAID WIRING PATTERN.
