Abstract: Provided is a method for industrially mass-producing a modified xylopolysaccharide from biomass. The biomass used as a raw material includes xylan in plant cell walls, having at least one kind of substituents selected from acetyl, feruloyl arabinofuranosyl and coumaroyl arabinofuranosyl groups in the side chains of xylan. A passage controlling mechanism is internally arranged to generate plug-flow onto a slurry containing the biomass at a solid content in 10 mass % to 30 mass %. The hydrothermal treatment is performed under the controlled conditions: at a temperature of 160° C. or more, at a pressure equal to or higher than the saturated water vapor pressure at said temperature, and with a reaction severity R0 ranging from 3000 to 7000. A modified xylopolysaccharide is obtained as preserving the substituents in the side chains of xylan by performing a continuous hydrothermal treatment in a cylindrical plug-flow reactor.

Abstract: Disclosed is a composition containing a specific oligosaccharide and a bivalent metal cation, which exhibits an effect on the amelioration, treatment or prevention of allergy or topical inflammatory reactions in an extremely safe and effective manner compared to synthetic oral steroid medicines in spite of a fact that the composition contains components that are generally familiar as a food or an ion occurring in living bodies and have no toxicity against living bodies when used at physiological concentrations. Specifically disclosed is a cell-cell adhesion enhancer in epithelial cells, which comprises 1-kestose and/or nystose and a bivalent metal cation as active ingredients.

Abstract: A highly safe, inexpensive and widely utilizable method, which has a mechanism backed by scientific grounds, for improving an activity of ROS (reactive oxygen species)-scavenging enzyme group; An increase in the amount of an enzyme or promotion of an enzyme activity of the ROS scavenging enzyme group such as superoxide dismutase, catalase or peroxidase is caused in an organism having the ROS-scavenging enzyme with one or two or more kinds of substances selected from the group consisting of erythritol, mannitol, sorbitol and xylitol in 0.01-10% administration concentration.

Abstract: A switchgear has an insulating container filled with an insulating gas, a fixed current-carrying shaft fixed airtightly to one opening of the insulating container, a fixed contact provided on an end of the fixed current-carrying shaft in the insulating container, a movable contact configured to separably contact the fixed contact, a movable current-carrying shaft having the movable contact provided on an end and airtightly movably penetrating the other opening of the insulating container, and an operation mechanism coupled with the movable current-carrying shaft at an outside of the insulating container. The insulating container is constituted by a plurality of insulating layers, and the insulating layers are higher in dielectric constant as closer to an inside of the insulating container.

Abstract: By molding a plurality of vacuum valves (7), (13) having differing functions together with an input member (3) and an output member (21) en bloc in a resin layer (23) to form a switch gear (1), the present invention seeks to achieve dielectric strength without resorting to the use of SF6 gas, while rendering the whole device more compact and reducing both the number of parts and the man hours required for molding.

Abstract: A molded electric device having an insulated casing made of ceramics that has higher dielectric strength. The molded electric device includes an insulated casing, an endplate, an electric component and an electric insulating layer. The insulated casing is made of ceramics and has an end and an unglazed outer surface. The endplate is fitted to the end of the insulated casing. The electric component is accommodated in the insulated casing by the endplate. The electric insulating layer is molded to the unglazed outer surface of the insulated casing.
