  • Patent number: 5824115
    Abstract: A cellulose fiber is immersed in a cellulose fiber dissolving agent such as tertiary amine-N-oxide, lithium chloride/N,N-dimethylacetoamide or N-methylmorpholine-N-oxide under conditions where the dissolving agent does not dissolve the cellulose fiber. Therefore, the water absorbing property and moisture absorbing and discharging property of the cellulose fiber can be improved without deteriorating the strength and feeling of the cellulose fiber.

  • Patent number: 5635468
    Abstract: The present invention relates to a liquefying alkaline .alpha.-amylase having the enzymatic properties described below, a production process thereof and a detergent composition containing the same.1) Action:It hydrolyzes .alpha.-1,4-glucosidic linkages in starches, amylose, amylopectin and partial degradation products thereof and from amylose, forms glucose (G1), maltose (G2), maltotriose (G3), maltotetraose (G4), maltopentaose (G5) and maltohexaose (G6). It however does not act on pullulan.2) Isoelectric point:It has an isoelectric point higher than 8.5 when measured by an isoelectric focusing electrophoresis.The amylase according to the present invention has a liquefying activity capable of permitting degrading starches and starchy polysaccharides at high random, and has an optimum pH on the alkaline side. Owing to the high isoelectric point, it can be purified readily. Detergents with the amylase incorporated therein have excellent detergency especially against the soil of smeared food.

  • Patent number: 4613401
    Abstract: The dry etching rate of a Cr film has been increased by adding ethyl or methyl alcohol vapor to an etchant gas containing a halide of a hydrocarbon such as CCl.sub.4 and oxygen gas. The dry etching rate increase is attributed to the reduction reaction of a dry etching product, CrO.sub.2 Cl.sub.2, into chemically stable CrCl.sub.3, the reduction reaction suppresses deposition of Cr generated by the decomposition of chemically unstable CrO.sub.2 Cl.sub.2.
