  • Patent number: 9283125
    Abstract: In a disposable wearing article, a first waist region is elasticized and formed of an inner sheet and an outer sheet. The non-skin-facing side of the outer sheet is formed substantially over its entire area with a plurality of thermocompression-bonded spots regularly and intermittently arranged at predetermined intervals. The outer sheet has non-thermocompressed regions surrounded by a plurality of thermocompression-bonded spots. A fibrous layer lying at least on the outer surface of said outer sheet is formed of thermal adhesive crimped fibers which are bonded together by thermocompression-bonding treatment in the thermocompression-bonded spots. The outer sheet and the inner sheet are bonded to each other by adhesive applied on at least one of respective opposite surfaces thereof so that the crimped fibers in the non-thermocompressed regions may protrude outward in a thickness direction of the outer sheet as the inner sheet contracts in the direction of the transverse axis Q.

  • Publication number: 20150372338
    Abstract: A non-aqueous electrolyte secondary battery includes an electrode wound body formed by winding positive and negative electrode sheets with separators interposed therebetween. The positive electrode sheet is manufactured through a coating process wherein a positive electrode mixture paste is applied to a current collecting sheet to form a mixture layer. Prior to the coating process, sections of the current collecting sheet to be uncoated and to be coated are differentiated in terms of wettability. Alternatively, a positive electrode mixture paste with viscosities at slow and fast shear velocities within a predetermined range is used. Thus, the cross-sectional shape of the width-direction end of the mixture layer includes a steep cross-sectional shape, wherein the width of a section as thin as or thinner than 50% of a thickness of a width-direction center flat portion of the mixture layer is 100 ?m or less.
