Abstract: [Problems] To prevent excrement, which is flown back on a diaper, from attaching to a gluteal region of a wearer while the diaper is not deteriorated in a capability of absorbing watery stool and the like [Means for Solving Problem] To a top sheet 30, comprising a widthwise central region 31 extending from front to back ends through a portion corresponding to an intergluteal cleft; left- and right-side intermediate regions 32, 32 that are positioned on left and right sides of the widthwise central region and extend from front to back ends through portions corresponding to left and right gluteal regions, respectively; and left- and right-side regions 33, 33 that extend from front to back ends along a left side of the left-side intermediate region and a right side of the right-side intermediate region, respectively, a large number of permeation holes H are formed at predetermined intervals in the widthwise central region 31, left-side region and right-side region 33, 33, respectively and no permeation hole H is

Abstract: [Problem]0 To provide a disposable diaper which can be used both as a tape-fastening type and an underpants type with an excellent fit. [Means for Solving Problem] By joining the both side portions of the front body part 12F and back body part 12B respectively to thereby form joined portions 12A on both sides along with a waist opening WO and a pair of right and left leg openings LO and in this diaper, perforated lines 100 are formed on the both side portions of the front body part 12F so as to extend from an edge of the waist opening WO to edges of the leg openings LO and at least one pair of fastening tapes 90 having hook members 92 on inner surfaces thereof and straddle the perforated lines.

Abstract: A process for recovering scandium economically with high efficiency by concentration and separation from an oxide ore containing nickel and a small amount of scandium as well as a large amount of iron and/or aluminum comprises the steps of acid leaching the oxide ore under a high-temperature, high-pressure oxidative atmosphere while restraining leaching of the iron and/or aluminum, thereby selectively leaching substantially all nickel and scandium from the ore, recovering the nickel from the resulting leaching solution as a precipitated sulfide while not precipitating the scandium as a sulfide but leaving the total amount thereof in the solution, and then adjusting the pH of the solution with a precipitant to recover the scandium from the solution as a high-concentration scandium hydroxide or carbonate by concentration and separation.

Abstract: A direct method for the production of high-grade, high-purity ferromanganese comprising the steps of charging a molten Mn-containing material, a non-carbonaceous reducing agent and a slagging material in a reaction vessel and subjecting the reaction vessel to horizontal eccentric circular motion to mix and agitate the contents of the vessel, whereby the Mn oxide contained in the molten Mn-containing material is reduced by the non-carbonaceous reducing agent.
