Abstract: A multilayer analysis sheet for analyzing liquid samples is described, comprising, in sequence, a light transmitting hydrophobic support having on one side thereof at least one layer containing at least one reagent in a binder and a liquid sample spreading layer made of fabric, which layers are laminated to form an integral unit together with the support, wherein said fabric has the ability to supply a liquid sample placed on the surface thereof to the reagent-containing layer at a substantially constant volume per unit area, which ability is conferred upon the fabric by rendering it hydrophilic; the multilayer analysis sheet can be economically manufactured without variations in quality, and improves the spreading capability of liquid samples.

Abstract: A thermal recording element comprising a support having formed thereon a recording layer, a first protective layer of a halogenated polyolefin, polystyrene, polystyrene derivative, halogenated rubber or styrene-vinyltoluene copolymer formed on the recording layer; and a second protective layer of a polymer having strong film strength formed on the first protective layer.

Abstract: An integrated material for chemical analysis comprising three or more reagent layer units on a support and a porous spreading layer, said units containing reagents for different chemical analyses and being proximately arranged on a support such that approximately equal portions thereof are within a spreading circle defined by the diffusion of a liquid sample as it passes through the porous spreading layer, and a method for analyzing blood using the same.

Abstract: A thermal recording element comprising a support having formed thereon a recording layer and formed on the recording layer, a protective layer containing a polymer, and a higher fatty acid having 10 or more carbon atoms or an amide thereof present in or on the protective layer.

Abstract: A multilayered integral chemical analysis element for the blood comprising a filter layer capable of removing formed components from the blood, a water-proof layer having at least one small opening therein, a porous spreading layer and a reagent layer laminated in this order.

Abstract: An integral multilayered element for the chemical analysis of the blood comprising a combination of a porous spreading layer, a reagent layer, and a radiation-blocking layer, said radiation-blocking layer being water-permeable and containing at least one elemental metal or an alloy thereof.

Abstract: An ion selection electrode device for measuring concentrations of predetermined ions such as in biological samples in which measuring electrodes are disposed on a planar substrate with their active heads lying within a circle of small radius. A small sample of a liquid to be measured is dropped on and spreads over the circle contacting each electrode. In a preferred embodiment, two sets of electrodes are provided around adjacent circles on a single substrate, one for the sample and the other for a standard reference fluid. A dam separates the two liquids but electrical contact therebetween is provided by a porous bridge.

Abstract: An integrated material for chemically analyzing a liquid sample comprising a supporting plate having provided thereon two or more different analytical units each comprising a reagent layer and a porous spreading layer or a portion of a common porous spreading layer, the units being disposed such that at least a portion of the reagent layers are in contact with or in close proximity to one another with the porous spreading layer(s) of the units being commonly covered with a liquid sample delivering patch.

Abstract: A process for forming an image is disclosed wherein a photo-sensitive image-forming material composed of a support and a layer of a thermoplastic photo-sensitive composition which is not adhesive at ordinary temperatures, is exposed and developed by heating in intimate contact with a peeling development carrier sheet at least one surface of which is composed of a thermoplastic material not adhesive at ordinary temperatures, and, subsequently, peeling the development carrier sheet from the photo-sensitive image-forming material.

Abstract: A method for treating a waste photographic processing solution containing a silver-sulfur compound comprising applying chemo-synthetic sulfur bacteria to the waste solution under aerobic conditions.

Abstract: A process of treating a waste photographic processing solution containing reductive sulfur compounds, in particular, a waste fix solution for silver halide photographic materials, by applying thereto photosynthetic sulfur bacteria under anaerobic conditions with the irradiation of light. When the waste solution contains silver, the decontamination of the waste solution and the recovery of silver are performed simultaneously by the process.

Abstract: Process of producing aspirin-containing capsules which comprises (1) dispersing aspirin particles in a solution of a cellulose derivative in an organic solvent partially miscible with water; (2) adding the dispersion to an encapsulation medium comprising water containing organic solvent(s) partially miscible with water with or without aspirin; (3) stirring the mixture to form a fine dispersion of the aspirin; and (4) evaporating off the organic solvent to deposit the cellulose derivative around the aspirin particles.

Abstract: A method for controlling the hydrogen ion concentration of an aqueous solution is provided, which method comprises adding to an aqueous solution, microcapsules prepared by encapsulating an acid material with a polymer, which is dissolved in or swelled with water in an alkaline state only, and/or microcapsules prepared by encapsulating an alkaline material with a polymer, which is dissolved in or swelled with water in an acid state only, and adding an aqueous acid solution or an aqueous alkaline solution to the system.
