    摘要： A process is provided for producing curable polyorganosiloxanes where noble metal oxides are used as hydrosilylation catalysts. The noble metals can be used in solid granular form or as part of a fixed bed, and do not form part of the final curable composition or cured product. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resins at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency) in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.

    摘要： There is provided a method for industrially producing a phosphor with high performance, in particular, high brightness. There is also provided a nitrogen-containing alloy and an alloy powder that can be used for the production method. A method for producing a phosphor includes a step of heating a raw material for the phosphor under a nitrogen-containing atmosphere, in which an alloy containing two or more different metal elements constituting the phosphor is used as the whole or part of the raw material for the phosphor, and in the heating step, the heating is performed under conditions such that the temperature change per minute is 50° C. or lower.It is possible to suppress the rapid progress of a nitridation reaction in heat treatment in producing the phosphor using an alloy for a phosphor precursor as the whole or part of the raw material, thereby industrially producing the phosphor with high performance, in particular, high brightness.

    摘要： Poly(L-lactic acid) was melt-spun at 200° C. and drawn to obtain a hollow monofilament 0.15 mm in outside diameter and 0.12 mm in inside diameter. The monofilament was cut to a length of 8 cm. Each of opposite ends of the cut piece was wound around a stainless steel mandrel, 1 mm in diameter, one-half turn, held in J-shaped curl, heat-treated at 150° C. and then cooled. In this way, a bioabsorbable vasoocclusive coil 3 of the invention was prepared which had a J-shaped curved portion 1 at each of opposite ends thereof and a hollow portion 2 over the entire length thereof. The hollow portion can be filled with a drug such as carcinostatic or antitumor agent, permitting the drug to exhibit a sustained release effect. When the follow portion is filled with an X-ray contrast mediums the coil can be delivered to a desired intravascular site reliably, while the process of treatment can be observed more reliably.

    摘要： A tape-shaped magnetic recording medium for executing recording/reproducing processes at a running speed 2m/sec or higher is capable of exhibiting an excellent running characteristic and making it hard to cause print-through as well. This magnetic recording medium comprises a non-magnetic support, a magnetic layer formed on one surface of the non-magnetic support body and containing at least ferromagnetic metal powders and binding agent resin, and a backing layer formed on an opposite surface thereof and containing at least a carbon black and the binding agent resin. In this magnetic recording medium, a three-dimensional root mean square value roughness Rq of the surface of the backing layer is 200 nm or above through 280 nm or under, and a three-dimensional distortion degree Rsk of the surface thereof is -0.2 or under: ##EQU1## where f(x, y) is the roughness surface expressed on the unit of nm on the definition that an X-Y plane is the roughness mean surface, a recessed portion is negative and a protruded portion is positive, and S represents an area of a roughness measurement area on the X-Y plane.
