Abstract
Abstract A thick film printed circuit in which a plurality of electrode patterns are disposed with approximately equal spaced intervals between one another, resistance patterns having approximately equal widths are mounted between adjacent electrode patterns of said plurality of electrode patterns, and an identical shaped resistance pattern to said resistance pattern is provided so as to align in parallel with at least one of said resistance patterns, whereby exact divided potential can be obtained.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
96 words
A thick film printed circuit including a potential dividing circuit having a plurality of printed resistance patterns for dividing voltage; said potential dividing circuit including: first, second and third electrode patterns; a first resistance pattern having a uniform width extending transversely across the first, second and third electrode patterns; and a second resistance pattern adjacent and in parallel to said first resistance pattern, said second resistance pattern having a width substantially equal to that of the first resistance pattern and extending between said second electrode pattern and only one of said first and third electrode patterns.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
A thick film printed circuit according to claim 1, wherein a plurality of said second resistance patterns are provided.
