Abstract: An aircraft window member includes film made of acrylic resin, a conductive mesh, which is formed on the film and in which a conductive material, is formed in a mesh shape so as to have optical transparency for ensuring visibility and to have electromagnetic-wave shielding properties, and a window main body, which is made of acrylic resin, and to which the film on which the conductive mesh is formed is attached.

Abstract: An aircraft window member excellent in durability, a method of manufacturing the same, and an aircraft window assembly are provided. The aircraft window member includes: a film made of acrylic resin; a conductive mesh which is formed on the film and in which a conductive material is formed in a mesh shape so as to have optical transparency for ensuring visibility and to have electromagnetic-wave shielding properties; and a window main body which is made of acrylic resin and to which the film on which the conductive mesh is formed is attached.

Abstract: A method of treating organic waste water in an aeration tank is characterized by the fact that (1) the dissolved oxygen content in the aeration tank is adjusted to be within the range of 1.5-4.5 ppm; (2) the temperature of the waste water is controlled to be within the range of 15.degree.-40.degree. C. and the residence time of the waste water in the aeration tank is set at ten or more days if the ratio of the total carbon content to the nitrogen content of the organic materials contained in the waste water (TOC/N) is not less than 5, and the temperature of the waste water is controlled to be within the range of 20.degree.-40.degree. C. and the residence time of the waste water in the aeration tank is set at ten or more days if the TOC/N is less than 5 and not less than 2.5, and (3) the activated sludge content in the aeration tank is kept constant by controlling the amount of COD to be removed according to the equation:.sigma.T=33.5.times.1.058.sup.(T-20)wherein T is a temperature (.degree.C.

Abstract: A process for preparing a free-flowing lactulose-containing powder from a solution containing lactose, by adding calcium hydroxide to the solution to adjust the pH of said solution to from 9.4 to 11.2; heating the resulting solution so that the pH is reduced to from 7.5 to 9.0; the homogenizing, concentrating and drying.

Abstract: Packaged aseptic soya bean curd containing no bactericidal agents is manufactured by a method which comprises continuously sterilizing a soya bean juice by maintaining it at a temperature of 128.degree. to 150.degree. C for 1 to 6 seconds and cooling to room temperature; homogeneously mixing said sterilized soya bean juice with a sterilized coagulating agent-containing solution in an aseptic atmosphere continuously or in a pipeline; continuously filling the resulting liquid mixture into a container in an aseptic atmosphere and sealing it; and dipping said sealed container into a water tank heated to 70.degree. to 95.degree. C for 20 to 60 minutes in order to coagulate the mixture.
