Abstract: An individual package of an absorbent article permits a base end of a tape to be bonded with sufficiently large bonding strength without complicating packaging process and increasing manufacturing cost. The absorbent article is wrapped by a package sheet having side edge portions and end edges, and one end edge is overlapped over the other end edge. The package sheet is sealed along the side edge portions, a base end of a tape is fixed on the surface of the package sheet located outside in an overlapping portion, and a free end of the tape extends across one end edge and is releasably adhered on the outer surface of the package sheet adjacent one end edge. The package sheet has a surface, on which the base end of the tape is fixed, the surface being smoothed by a smoothing process.

Abstract: Provided is a lightning-protection fastener that is capable of reliably preventing peeling off of an insulation layer during the operation of an aircraft and of improving the anti-lightning-strike capability and reliability. There is a lightning-protection fastener that fastens a skin of an aircraft and a structural member positioned inside the skin, in which an insulation layer is melt adhered so as to cover one end surface of a head portion and also to mechanically engage with a fastener-side engagement portion (engagement portion) formed on the end surface.

Abstract: The present invention aims to provide an absorbent article adapted to maintain a desired flexibility of the topsheet and to prevent the article from becoming glossy. A sanitary napkin 1 comprises a topsheet 2 defining an inner side facing the wearer's skin, an outer side facing the wearer's garment, a liquid-absorbent structure 4 interposed between these top- and backsheets 2, 3, and a cushion sheet 5 interposed between the liquid-absorbent structure 4 and the topsheet 2. The topsheet 2 is formed with a plurality of pores 6 assuring liquid-pervious property thereof. The pores 6 are distributed over an entire area of the topsheet 2 and extending through the topsheet 2 in its thickness direction. The topsheet 2 is debossed to form a plurality of concavities 13 directed toward the side of the cushion sheet 5.

Abstract: A fiber laser light source is provided with a laser resonator including a pair of fiber gratings optically connected to a fiber in a state that the fiber is interposed between the paired fiber gratings. The reflection center wavelength of a laser-exit side fiber grating, out of the paired fiber gratings, lies in a wavelength range where the reflectance of a fiber grating, out of the paired fiber gratings, closer to the pump laser light source is not smaller than 80% but not larger than 98%.

Abstract: A distributed fiber optic sensor device that employs a photonic band gap fiber as a sensing medium, in which: the photonic band gap fiber, which is the sensing medium, includes: a quartz section; and a plurality of high refractive index portions provided in the quartz section along the longitudinal direction of the fiber, the high refractive index portions being photonic band gaps periodically arranged to form a triangular-lattice pattern; the photonic band gap fiber has a bandwidth in which a wavelength band of a Stokes beam generated due to stimulated Raman scattering is included; and the photonic band gap fiber has a band gap width in which a wavelength band of an anti-Stokes beam generated due to the stimulated Raman scattering and a wavelength band of an optical signal incident into the photonic band gap fiber are included.

Abstract: Disclosed is a sanitary napkin having extensions, parts of which are to be folded back and fixed on an undergarment in use. The sanitary napkin includes: a liquid-permeable topsheet disposed on one side of the sanitary napkin to cover a central region thereof; a backsheet; an absorbent layer disposed therebetween; and leakage preventing portions disposed on laterally opposed side portions of the topsheet and extending in a longitudinal direction of the sanitary napkin. Joints between the respective leakage preventing portions and the topsheet are formed to extend in the longitudinal direction. The extensions are portions of the sanitary napkin extending laterally outwardly beyond the joints. Each extension includes a flexible region for facilitating folding thereof, which is spaced laterally outwardly apart from corresponding one of the joints and has a stiffness lower than that of a region between the flexible region and the corresponding joint.

Abstract: Disclosed is an absorbent article having a liquid acquisition layer between a topsheet and a liquid absorbent layer. The liquid acquisition layer is an absorbent sheet that is three-dimensionally deformed to include: longitudinal ribs projecting toward the topsheet and extending parallel with each other in a longitudinal direction of the article; and transverse ribs projecting toward the topsheet and extending in a transverse direction of the article. The transverse ribs are arranged at intervals in the longitudinal direction and connect adjacent longitudinal ribs, thereby providing a plurality of recesses surrounded by the longitudinal ribs and the transverse ribs. At least the longitudinal ribs are in contact with an overlying component, whereas bottoms of the recesses are in contact with the liquid absorbent layer.

Abstract: A napkin package is difficult to form permanent folding, twisting or corrugation in a leakage preventing wall as folded and wrapped by a packaging sheet, to ensure raising of the leakage preventing wall from a surface of a sanitary napkin after opening the package for achieving satisfactory side leakage preventing effect. A sanitary napkin has longitudinally extending leakage preventing walls on both sides of a liquid absorbing portion. A reinforcement sheet is provided on a surface side of a folded sanitary napkin with covering a portion of the folding line, the reinforcement sheet is bent at a position corresponding to the folding line without forming crease, and portions of the leakage preventing walls located corresponding to the portion across which the folding line extends, are urged onto an outer surface of the bent portion of the reinforcement sheet by the elastic tension force.

Abstract: Disclosed is a hygiene product including a sanitary napkin, a release sheet and a packaging sheet. Wing portions of the sanitary napkin are folded back against a body surface of a main body portion of the sanitary napkin, and pressure sensitive adhesive layers of the wing portions are covered with the release sheet. A stack of the packaging sheet, the sanitary napkin and the release sheet are so folded into the hygiene product that only the packaging sheet is exposed externally. A portion of the packaging sheet protruding rearwardly from a rear end of the sanitary napkin is bonded to an exterior surface of the release sheet at a position spaced rearwardly away from the pressure sensitive adhesive layers of the wing portions.

Abstract: A sanitary napkin has an absorbent core convexly curved upward and the absorbent core is provided on its lower side with a pad adapted to hold a curved shape of the absorbent core. The pad is formed on its upper side with a plurality of projections and continuous troughs so that the projections are bonded to the lower side of the absorbent core and the troughs form a continuous tunnel between the absorbent core and the pad. The pad thus formed improves a breathability of the sanitary napkin during its use.
