摘要:
An ionic activity measuring device comprises ion selective electrodes, porous liquid distributing members for distributing a reference solution and a sample solution to the ion selective electrodes, a frame for housing the ion selective electrodes and the porous liquid distributing members and provided with a pair of liquid feed holes for feeding the reference solution and the sample solution to the porous liquid distributing members, and a porous bridge for achieving electrical conduction between the reference solution and the sample solution fed in drops to the liquid feed holes. The porous bridge is disposed in a recess formed in the surface of the frame so that the depth of the recess is not smaller than the height of the porous bridge. End portions of the porous liquid distributing members are protruded to regions under the liquid feed holes so that the fed solutions may enter from side faces of the end portions. The porous bridge may extend at positions deviated from centers of the liquid feed holes. The frame may be provided with holes for insertion of potential measuring probes, and air discharging holes.

An apparatus for measuring ionic activity is comprised of a rotatable turret and at least one pair of vertically movable probes. The turret intermittently conveys slide-type ionic activity measuring devices, one by one, on each of which are spots of reference and sample solutions, to a measuring section where the probes come into contact with the measuring device so as to measure the potential difference corresponding to the difference in ionic activity of a specific ion between the reference and sample solutions. After measurement the turret further conveys the device to a discharging section where the device is automatically discharged.
摘要:
A device for determining ionic activity composed of, as essential components, plural pairs of ion-selective solid electrodes each pair having two electrodes (one electrode on each of two sides) and each pair having a different ion-selective layer; two liquid distribution porous members, each member disposed over all the electrodes of each said side of the plural pairs; and a porous capillary bridge disposed on or between the liquid distribution porous members. The bridge can be in liquid contact with all the electrodes through the liquid distribution porous members and achieve electrical conduction between two electrodes in each pair after spotting a test solution and a reference solution. The device preferably further comprises a support frame and a cover having two apertures for liquid spotting. The device can simultaneously determine ionic activities of a plurality of different ions in a test solution, such as whole blood, plasma, serum, urine, etc., by spotting a test solution and a reference solution each in one operation and measuring an electrical potential difference of each pair.
摘要:
A conductive layer is formed on an insulating base, and at least one groove is formed in the conductive layer by cutting a part of the material of the conductive layer so that the conductive layer is divided into at least a pair of portions electrically isolated from each other by the cut groove. Thereafter, an ion selective layer is formed on the conductive layer to cover substantially the entire surface of the conductive layer including the cut groove.

A vertical filling and packaging machine of the present invention includes tension devices (11) that are disposed near positions of ironing rollers (5) and that pull both sides of cylindrical film (1) laterally outward. Tension devices (11) pull both sides of cylindrical film (1) laterally outward to flatten a portion of cylindrical film (1) before the pair of ironing rollers (5) sandwiches the portion of cylindrical film (1), wherein the content has been injected into the cylindrical film (1). As a result, when lateral seal part (1e) is formed on cylindrical film (1) by lateral seal device (6), lateral seal part (1e) is not easily wrinkled.
