Abstract
Abstract A multi-pin record electrode assembly comprises two series of record electrodes formed on the same substrate and folded to form a zigzag pattern with respect to each other. The electrodes are formed on a flexible substrate having a fold line separating the substrate into two substrate portions. Each substrate portion has an electrode set and its associated leads formed thereon. The substrate is folded along the fold line to produce the record electrode assembly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A multi-pin record electrode assembly comprising: an insulating substrate folded into two substrate portions along a fold line; and first and second electrode sets formed on said substrate along said fold line, said first electrode set including a plurality of closely spaced electrodes arranged at a predetermined distance from each other along a first side of said fold line, said second electrode set including a plurality of closely spaced electrodes arranged at said predetermined distance from each other along a second side of said fold line, said second electrode set being offset along said fold line from said first electrode set approximately one half said predetermined distance said electrodes of each set are spaced from each other; said substrate being folded so as to form a record electrode assembly having an edge formed along said fold line, said first and second electrode sets having alternating electrodes presented along said edge.
Claim 2
Dependent Claim
150 words
A multi-pin record electrode assembly comprising: an insulating substrate folded into two substrate portions along a fold line; and first and second electrode sets formed on said substrate along said fold line, said first electrode set including a plurality of closely spaced electrodes arranged at a predetermined distance from each other along a first side of said fold line, said second electrode set including a plurality of closely spaced electrodes arranged at said predetermined distance from each other along a second side of said fold line, said second electrode set being offset along said fold line from said first electrode set approximately one half said predetermined distance said electrodes of each set are spaced from each other; said substrate being folded so as to form a record electrode assembly having an edge formed along said fold line, said first and second electrode sets having alternating electrodes presented along said edge.
Claim 3
Dependent Claim
49 words
The electrode assembly of claim 1, wherein said first and second substrate portions each have inner surfaces juxtaposed to each other when said substrate is folded, said inner surace of said first substrate portion being folded to lie substantially coplanar to the inner surface of said second substrate portion.
Claim 4
Dependent Claim
27 words
The electrode assembly of claim 2, wherein said first and second electrode sets are formed on the inner surfaces of said first and second substrate portions, respectively.
Claim 5
Dependent Claim
35 words
The electrode assembly of claim 3, further comprising: an insulating film disposed between the inner surfaces of said first and second substrate portions for electrically isolating said first and second electrode sets from each other.
Claim 6
Dependent Claim
37 words
The electrode assembly of claim 2, further comprising: lead lines connected to each electrode of said first and second electrode sets, each of said lead lines extending perpendicularly from said fold line and parallel to each other.
Claim 7
Dependent Claim
32 words
The assembly of claim 2, further comprising: a shield disposed on the outer surface of each of said first and second substrate portions to electrostatically isolate said first and second electrode sets.
Claim 8
Dependent Claim
14 words
The multi-pin record electrode assembly according to claim 1, wherein said substrate is flexible.
Claim 9
Dependent Claim
25 words
The assembly of claim 1, further comprising: an auxiliary substrate bonded to the outer surface of said substrate portions, said auxiliary substrate being relatively rigid.
Claim 10
Dependent Claim
59 words
The electrode assembly of claim 1, wherein each of said electrodes has a width along said fold line approximately equal to said predetermined distance between adjacent electrodes, said electrodes of said first and second electrode sets alternating so as to substantially continuously cover the length of said fold line upon which said first and second electrode sets are disposed.
