Abstract: Disclosed is a novel hydrous composite oxide of cerium (IV) and phosphorus characterized by the specified chemical composition and the unique X-ray diffractometric pattern, which is useful as an adsorbent or immobilizing agent of strontium ions in an aqueous solution such as radioactive wastes from atomic power plants. The composite oxide prepared by the precipitation reaction of a Ce (IV) salt in an aqueous solution and phosphoric acid can be imparted with an increased adsorption capacity for strontium ions when the precipitates are heat-treated under hydrothermal conditions at up to 300.degree. C. Immobilization of strontium ions adsorbed on the adsorbent can be more complete when the adsorbent bearing strontium ions is dried and subjected to a heat treatment at a temperature of 200.degree. C. or higher.

Abstract: A terminal fixing structure which includes a cylindrical ceramic base with a conductive contact on the side and a metal thermal with a pair of resilient arms for holding the side of the ceramic base and for contacting the conductive contact. The ceramic base has an engaging receptor on the side and each of the arms has an engaging portion for engaging with the receptor. Since the engaging receptor (e.g., ring grooves) of the ceramic base is firmly engaged with the engaging portion (e.g., teeth), the ceramic base and the terminal will not be separated from each other by a vibration, etc. An oxygen sensor using this terminal fixing structure is one possible application.

Abstract: Disclosed is a method for measuring changes in a physical property of a liquid or semisolid material which comprises placing a thin metal wire in the material; passing an electric current through the thin metal wire in such a way that the temperature difference between the material and the thin metal wire is kept constant; measuring the intensity of the electric current; and calculating the heat transfer coefficient at the surface of the thin metal wire on the basis of the measured intensity of the electric current and thereby detecting changes in a physical property of the material. This method makes it possible to detect, for example, changes in the coefficient of kinematic viscosity of a food having the form of a gel or changes in the condition of thrombus formation in a blood vessel.

Abstract: Surimi suitable for the production of Kamaboko (fish meat jelly) can be obtained at high yield by compounding (1) a salt-soluble protein fraction prepared by mincing fish meat taken from raw fish into a sol-form, water-washing the resulting sol and dewatering and then subjecting the same to a salt-solution treatment, with (2) heat-denaturated water-soluble protein fractions prepared by heating to coagulation water-soluble protein fractions leached out in the water-wash and salt-solution treatment.

The method involves forming a slurry of fish meat in a neutral buffer solution containing divalent metal ions and polyvalent weak-acid anions. The anions are present in an amount sufficient to sequester the metal ions. The slurry is converted to a fish meat powder by spray-drying.
