摘要:
A linear stimulating ray source produces stimulating rays and linearly irradiates them to a portion of a stimulable phosphor sheet, on which a radiation image has been stored. A photoelectric read-out system divides light, which is emitted from the portion of a front surface of the stimulable phosphor sheet exposed to the stimulating rays and/or the portion of a back surface of the stimulable phosphor sheet corresponding to the portion of the front surface exposed to the stimulating rays, into picture elements along a length direction of the portion exposed to the stimulating rays, and photoelectrically reads out the divided picture elements by arraying them in a two-dimensional form. A scanning system moves the stimulable phosphor sheet with respect to the linear stimulating ray source and the photoelectric read-out system and in a direction, which is approximately normal to the length direction of the portion exposed to the stimulating rays.

@ A device is disclosed for measuring ionic activity of ions contained in solutions. The device comprises a lower supporting frame, at least one pair of ion-selective electrodes, an upper supporting frame made of a thermoplastic material having at least one pair of apertures for spotting reference and sample solutions, and at least one porous bridge for effecting an electrical conduction between both solutions. Both ends of the porous bridge are fixed on the upper supporting frame by softening or melting of the the thermoplastic material such that the porous bridge is extended over the pair of the apertures.
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.

57 An apparatus for measuring ionic activity is comprised of a rotatable turret (13A) and at least one pair of vertically movable probes (14A). The turret (13A) 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 (14A) 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 (13A) further conveys the device to a discharging section (15) where the device is automatically discharged. The reference solution is preferably dripped through a nozzle (12C) connected to a reservoir (12A) when the measuring device is located at a position below the nozzle (12C).
