Abstract
Abstract Thick film resistors, particularly useful as elements in a resistive voltage divider on a common substrate, are shown to consist of pluralities of substantially identical segments connected in series or in parallel to obtain desired resistance values, each successive pair of such segments being joined through a low resistance connection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
A thick film resistor disposed on a substrate between a first and a second terminal, such resistor comprising: (a) a plurality of similarly shaped electrically conductive pads disposed on the substrate at equal distances between the first and the second terminal; and (b) a thick film resistor in the shape of a strip on the substrate interconnecting the first and the second terminals, such resistor overlying each one of the plurality of similarly shaped electrically conductive pads.
Claim 2
Dependent Claim
77 words
A thick film resistor disposed on a substrate between a first and a second terminal, such resistor comprising: (a) a plurality of similarly shaped electrically conductive pads disposed on the substrate at equal distances between the first and the second terminal; and (b) a thick film resistor in the shape of a strip on the substrate interconnecting the first and the second terminals, such resistor overlying each one of the plurality of similarly shaped electrically conductive pads.
Claim 3
Dependent Claim
30 words
A thick film resistor as in claim 1 wherein the plurality of similarly shaped electrically conductive pads divide the strip making up the thick film resistor into substantially equal segments.
Claim 4
Dependent Claim
120 words
A resistive voltage divider incorporating thick film resistors disposed on a substrate, such divider comprising: (a) a first, a second and a third terminal on the substrate; (b) electrically conductive pads on the substrate at points between the first and the second terminal; and (c) a first and a second thick film resistor of similar cross-sectional shapes interconnecting the first, second and third terminals, the second such resistor connecting the second and the third terminal and the first such resistor connecting the first and the second terminal and overlying the "N" electrically conductive pads at equally spaced points along the length thereof, the overall length of such first resistor being equal to ("N"+1) times the length of the second resistor.
Claim 5
Dependent Claim
120 words
A resistive voltage divider incorporating thick film resistors disposed on a substrate, such divider comprising: (a) a first, a second and a third terminal on the substrate; (b) electrically conductive pads on the substrate at points between the first and the second terminal; and (c) a first and a second thick film resistor of similar cross-sectional shapes interconnecting the first, second and third terminals, the second such resistor connecting the second and the third terminal and the first such resistor connecting the first and the second terminal and overlying the "N" electrically conductive pads at equally spaced points along the length thereof, the overall length of such first resistor being equal to ("N"+1) times the length of the second resistor.
Claim 6
Dependent Claim
22 words
The resistive voltage divider as in claim 3 having, additionally, means for adjusting the resistances of the first and the second resistors.
