Abstract: Provided is an abrasion-resistant polyester fiber, which has, in particular, a strength within a specific range, an elongation within a specific range and a Young's modulus falling within a specific range in a specific elongation range on a stress-strain curve, to improve the abrasion resistance of a woven/knitted product for clothing using, in particular, a fine size polyester fiber. The polyester fiber is an abrasion-resistant polyester fiber comprising ethylene terephthalate as a main repeating unit, characterized by satisfying the following requirements: (1) the fineness being from 8 dtex to 200 dtex inclusive; (2) the single yarn fineness being from 1.0 dtex to 4.0 dtex inclusive; (3) the breaking strength being 3.5 cN/dtex or greater; (4) the breaking elongation being from 20% to 50% inclusive; and (5) the minimum differential Young's modulus being 20 cN/dtex or less in an elongation range of from 2% to 5% inclusive on a stress-strain curve of the fiber.

Abstract: A fire distinguishing device includes: a detection device which detects an outbreak of a fire; a fire presence/absence distinguishing device which distinguishes the presence or absence of the fire; and a cumulative time determining device which determines the cumulative time required for distinguishing the presence or absence of the fire, in the fire presence/absence distinguishing device. The cumulative time determining device distinguishes an environment type of an environment where the detection device is installed, or a phenomenon type of a phenomenon being detected by the detection device, and further determines the cumulative time according to the distinguished environment type or phenomenon type.

Abstract: An immunochemical method is provided for the detection and determination of an analyte. The zeta potential of a latex-particle loaded with an immunologically active substance is measured before and after bringing the loaded latex-particle into contact with an analyte. The difference in zeta potential is correlated with changes of zeta potential for known concentrations of the analyte in order to determine the presence and amount of the analyte.

Abstract: A display device includes first and second light sources. Lights emitted from the first and second light sources respectively provide different illumination effects on a display face so that a combination of the first and second light sources provides variety of illumination patterns.

Abstract: For a crane having a boom for hanging loads apparatus for detecting overload is provided which comprises a boom bending moment set value generator, which is determined by a variable quantity corresponding to the operating radius of the crane, a boom bending moment detector having transversely spaced strain gauges mounted on the boom, a comparator for comparing the output of the boom bending moment set value generator with the averaged output of the boom bending moment detector, and means operated by the output of the comparator which is produced when the output of the detector exceeds the output of the boom bending moment set value generator.
