    摘要： In a heavy duty pneumatic radial tire, at least one carcass layer is provided between right and left bead portions and at least two belt layers formed of steel cords which exhibit a breaking elongation of 4% or less are arranged in an outer periphery of the carcass layer in a tread portion. The belt layers are composed of at least one upper belt layer (A) and at least one lower belt layer (B). The upper belt layer (A) has a belt width that is 0.6 times or less a carcass line maximum width SW of the carcass layer at a tire section and the lower belt layer (B) has a belt width such that both end portions thereof extend to tread shoulder portions. An inclination angle of the steel cords of the lower belt layer (B) relative to a tire circumferential direction is set to be larger than that of the upper belt layer (A). A ratio (Mb.sub.2 .multidot.N.sub.2)/( Mb.sub.1 .multidot.N.sub.1) of a product of a bending rigidity Mb.sub.2 per steel cord of the lower belt layer (B) and the number N.sub.2 of the steel cords per unit width of the lower belt layer (B) to a product of a bending rigidity Mb.sub.1 per steel cord of the upper belt layer (A) and the number N.sub.1 of the steel cords per unit width of the upper belt layer (A) is set to be at a range of 0.2 to 0.65.

    摘要： A lactulose syrup suitable for use in the production of foods and drugs is produced by the alkali isomerization of lactose. Elimination of monosaccharides formed in the reaction mixture, such as galactose, is conducted by passing the reaction mixture through a column packed with beads of a strongly-acidic chromatographic cation-exchange resin, said beads having substantially the same crosslinking degree, and then collecting lactulose-containing eluate fractions. This process is suitable for the industrial production of a high-purity lactulose syrup.

    摘要： A heavy-duty radial tire having a belt layer comprising at least four metallic cord layers of first, second, third, and fourth belts in that order from the carcass layer towards the tread. The first belt has a cord angle of 40.degree. to 75.degree. relative to the circumferential direction of the tire and is split into left and right portions provided on left and right shoulder portions, respectively, so as to provide a space in the central region of a crown portion provided with either at least one organic fiber cord layer having a total tensile strength per unit width of at least 240 kgf/cm and a cord angle of 0.degree. to 10.degree. or an inextensible fiber cord layer having a two-layer structure wherein the sum of the tensile moduli per unit width in the initial tension of all the cords is at least 1.3.times.10.sup.3 kgf/cm, the cord angle is larger than 0.degree. and two layers in the two-layer structure cross each other at an absolute angle smaller than the cord angle of the second and third belts. The second belt comprises cords provided at a cord angle of 22.degree. to 30.degree.. The third belt comprises cords crossing the cords constituting the second belt and provided at a cord angle of 10.degree. to 16.degree.. The fourth belt comprises cords provided at a cord angle of at least 18.degree..

    摘要： A heavy duty pneumatic radial tire,wherein a main area of contact with the road provided on a tread surface is formed with a circular arc, having a large radius of curvature, which crosses another circular arc having a small radius of curvature, Ra, to form an edge-shaped boundary, said radius of curvature, Ra, being larger than the depth of main grooves provided in said main area of contact with the road and smaller than the value five times as much as the depth of said main grooves,wherein narrow grooves provided on the shoulder portions are linearly provided in the circumferential direction of the tire and at a distance of 1.5 to 5 mm away towards the center of the tread surface from said edge-shaped boundary and have a groove width in the range of 1.5 to 5 mm, the direction of said narrow groove being inclined at an angle in the range of 1.degree. to 5.degree. relative to the perpendicular to the rotating shaft of the tire, the bottoms of said narrow grooves and the bottoms of said main grooves being present on an imaginary line drawn parallel to the circular arc of said main area of contact with the road, andwherein the widths of the partitioned ribs, located on the side of the center of the tread surface, among the partitioned ribs formed by partition with said narrow grooves, are equal to or larger than the maximum width of the remaining ribs which are present near the center of the tread surface as compared with said partitioned ribs.

    摘要： The present invention relates to an improvement in the cooling efficiency of an air cooling and vent device for use with a belt drive type power transmission for an all terrain vehicle, wherein cooling air introduced into a belt drive casing by an air suction fan built integrally with a drive pulley of the transmission is forced out of an air outlet provided in the middle position between the drive pulley and a driven pulley to the atmosphere by the suction effect of a cooling fan of the engine.
