Abstract
Abstract A potential dividing circuit comprising a plurality of independent electrode patterns spaced equally between two electrode patterns, and a resistance pattern having uniform width is provided between said two electrode patterns; wherein any one of said plurality of independent patterns is an electrode and another of the remaining independent electrode patterns is adapted to serve as dummy electrodes, whereby exact divided voltage can be obtained.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
A thick film printed circuit including a potential dividing circuit formed from a plurality of printed resistance patterns for dividing voltage applied to the potential dividing circuit in the ratio of m:n, said potential dividing circuit comprising n+1 electrode patterns equally spaced from one another and a resistance pattern having a constant width printed transversely of each of said electrode patterns; said potential dividing circuit including means for applying a predetermined voltage between the first of said electrode patterns and the (n+1)th electrode pattern, and means including the (n+1-m)th electrode pattern in said plurality of electrode patterns for receiving a potential divided from said predetermined potential.
Claim 2
Dependent Claim
106 words
A thick film printed circuit including a potential dividing circuit formed from a plurality of printed resistance patterns for dividing voltage applied to the potential dividing circuit in the ratio of m:n, said potential dividing circuit comprising n+1 electrode patterns equally spaced from one another and a resistance pattern having a constant width printed transversely of each of said electrode patterns; said potential dividing circuit including means for applying a predetermined voltage between the first of said electrode patterns and the (n+1)th electrode pattern, and means including the (n+1-m)th electrode pattern in said plurality of electrode patterns for receiving a potential divided from said predetermined potential.
Claim 3
Dependent Claim
34 words
A printed circuit as set forth in claim 1, one of said electrode patterns including a dummy electrode connected electrically to said resistance pattern and to no other circuit component of the printed circuit.
Claim 4
Independent Claim
91 words
A method for dividing voltage applied to a potential dividing circuit of a thick film printed circuit in the ratio of m:n, said potential dividing circuit comprising n+1 electrode patterns equally spaced from one another and a resistance pattern having a constant width printed transversely of each of said electrode patterns; the steps including: applying a predetermined voltage between the first of said electrode patterns and the (n+1)th electrode pattern, and receiving a potential divided from said predetermined potential by using the (n+1-m)th electrode pattern in said plurality of electrode patterns.
Claim 5
Independent Claim
91 words
A method for dividing voltage applied to a potential dividing circuit of a thick film printed circuit in the ratio of m:n, said potential dividing circuit comprising n+1 electrode patterns equally spaced from one another and a resistance pattern having a constant width printed transversely of each of said electrode patterns; the steps including: applying a predetermined voltage between the first of said electrode patterns and the (n+1)th electrode pattern, and receiving a potential divided from said predetermined potential by using the (n+1-m)th electrode pattern in said plurality of electrode patterns.
Claim 6
Dependent Claim
33 words
A method as set forth in claim 3, one of said electrode patterns including a dummy electrode connected electrically to said resistance pattern and to no other circuit component of the printed circuit.
