    摘要: A dry-etching method for working SiO.sub.2, phospho-silicate glass, Si, Mo, W, Cr, TiW, Si.sub.3 N.sub.4 or the like by the use of a glow discharge plasma involves the steps of introducing He, Ar, N.sub.2, O.sub.2 or a mixed gas thereof into a reaction chamber from the outside; and effecting the plasma discharge in the reaction chamber so that a reactive gas is liberated from a high molecular resin material arranged in the reaction chamber and containing fluorine atoms. The dry-etching method requires and uses no expensive gas containing a fluorocarbon, but has sufficient etching rate and selectivity.

    摘要: A method for dry-etching Al and Al alloys is disclosed, which comprises producing plasma discharges with a mixed gas comprising boron trichloride and freon and/or oxygen incorporated therein and patterning Al or an Al alloy by the produced discharges. In this dry etching method, the etch rate of Al or an Al alloy can be remarkably improved over the etch rate attainable according to the conventional techniques, and the difference of the etch rate between Al or an Al alloy and other material can be remarkably increased.

    摘要: This invention relates to a fine processing of aluminum and aluminum alloy layers, and to a method for dry etching by a plasma in a gas containing hydrogen and/or a gaseous hydrogen compound and further containing a gaseous chloride. The fine processing without suffering from the side-etching is feasible even in case using an inorganic material as a mask.

    摘要: This invention relates to biological treatment of waste water using a carrier floatable on water, and more particularly to a novel process for treatment of waste water utilizing a fluidized bed which is formed by supplying waste water in a downflow operation. The process for treatment of waste water of this invention is applicable to both anaerobic and aerobic biological treatment. A good example of the former anaerobic biological treatment to which this invention is applicable is the process wherein the nitrate or nitrite nitrogen which is one of the nitrogen compounds that are at present believed to be one cause of the eutrophication in rivers, lakes, seas, etc. is treated with denitrifying bacteria in an anaerobic condition to be released in the form of nitrogen gas, and the typical of the latter aerobic treatment is the practice in the utilization of the action of the aerobic bacteria which can oxidize organic substances in sewage, industrial waste waters, etc.

    摘要: A method for preparing a conductive thermoplastic resin composition or an electric conductor includes the step of kneading (a) conductive resin master batch pellets of conductive carbon black and a thermoplastic resin in which the conductive carbon black accounts for 5 to 50% by weight relative to the total amount 100 parts by weight of the conductive carbon black and the thermoplastic resin, (b) a thermoplastic resin in a weight ratio: (a+b)/(a) ranging from 1.01 to 1.5. This method permits the production of a conductive carbon black-containing conductive resin composition and an electric conductor which show stable conductivity even within a high resistance region (having a surface resistivity ranging from 10.sup.6 to 10.sup.16 .OMEGA.), wherein the control of the conductivity is difficult.
