Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
A method of assembling a dry type chemical analysis slide having a plurality of plate members formed of thermoplastic resin and a mount which holds a detecting element formed by the use of an electrode film and is integrally sandwiched between the plate members, said method comprising the following steps: (a) forming at least one of the plate members by extrusion into a continuous strip with a plurality of recesses on one side which respectively correspond to electrode receiving recesses of said at least one plate member; (b) winding up the continuous strip into a roll; (c) longitudinally unwinding and conveying said extruded continuous strip member in parallel with a plurality of other continuous strips which correspond to the other of said plurality of plate members while forming any required openings therein; (d) laminating said extruded continuous strip and said plurality of other continuous strips together so as to form a single laminated strip; and (e) stamping out individual chemical analysis slides from said laminated strip.
Claim 2
Independent Claim
166 words
A method of assembling a dry type chemical analysis slide having a plurality of plate members formed of thermoplastic resin and a mount which holds a detecting element formed by the use of an electrode film and is integrally sandwiched between the plate members, said method comprising the following steps: (a) forming at least one of the plate members by extrusion into a continuous strip with a plurality of recesses on one side which respectively correspond to electrode receiving recesses of said at least one plate member; (b) winding up the continuous strip into a roll; (c) longitudinally unwinding and conveying said extruded continuous strip member in parallel with a plurality of other continuous strips which correspond to the other of said plurality of plate members while forming any required openings therein; (d) laminating said extruded continuous strip and said plurality of other continuous strips together so as to form a single laminated strip; and (e) stamping out individual chemical analysis slides from said laminated strip.
Claim 3
Dependent Claim
45 words
A method of forming a dry type chemical analysis slide according to claim 1, wherein said extrusion step (a) includes forming said plurality of recesses on an upper surface of said continuous strip and forming a single bridge receiving groove on a lower surface thereof.
