    摘要： The present invention relates to a nozzle suitable for jetting high pressure and high temperature steam, and a method and an apparatus for producing an entangled nonwoven fabric using the nozzle. According to the apparatus, a steam inlet side main conduit (c1) and a steam outlet side conduit (c3) are connected with both end parts of a tubular nozzle holder (11) in a longitudinal direction provided integrally with nozzle members (15, 16, 23) having a plurality of nozzle holes (16a, 26). A steam outlet side conduit (c2) is provided with an opening/closing valve (55) and a trap conduit (57) is branched from a conduit at an upstream side from the opening/closing valve (55). By opening the opening/closing valve (55), a rapid temperature rise of the nozzle holder (11) can be enabled at a time of starting a production of a nonwoven fabric. Furthermore, even in the opening/closing valve (55) is closed in a regular operation, drainage generated inside the nozzle holder (11) can always be discharged to outside so that steam can be jetted stably and continuously, and thus a high quality entangled fiber nonwoven fabric can be produced continuously from the fiber web by the steam.

    摘要： A method for the preparation of a carbonate spring by supplying carbon dioxide to a carbon dioxide dissolver and dissolving the carbon dioxide in raw water, which comprises the steps of measuring the pH of the formed carbonate spring, calculating the carbon dioxide concentration data of the formed carbonate spring from the measured pH value and the alkalinity of the raw water, and controlling the feed rate of the carbon dioxide supplied to the carbon dioxide dissolver so as to make the carbon dioxide concentration data equal to a preset target carbon dioxide concentration value. According to this method, a carbonate spring having a desired concentration can be easily prepared by using an inexpensive pH measuring device.

    摘要： This invention provides an optical copolymer which is excellent in balance among high transmittance, high heat resistance, low birefringent property, and mechanical strength, and an optical molded article comprising the optical copolymer. The optical copolymer comprises 50 to 80% by mass of methyl methacrylate units, 10 to 20% by mass of units derived from a specific lactone compound, and 10 to 30% by mass of trifluoroethyl methacrylate units. The mass ratio of the trifluoroethyl methacrylate units is in the range of 0.5 to 2.0 when the mass of the units derived from the specific lactone compound is presumed to be 1, and the glass transition temperature is 120°C or above. The optical copolymer is suitable for objective lenses, prisms, condenser lenses, diffraction gratings, collimator lenses and sensor lenses.
