Abstract: A gas sensor (1) including a sensor element (10); a metallic shell (138); a tubular outer surface member (190) attached directly or indirectly to the metallic shell, constitutes an outer surface of the gas sensor, and extends toward a rear end side in relation to the metallic shell; and a tubular protection member (210, 220) which is detachably fixed to a fixation region C1, C2 of an outer circumference of the outer surface member. The protection member includes a first arc portion (212), a second arc portion (222), and a fixation portion (214,224) brought into contact with and is fixed to the fixation region.

Abstract: The problem to be solved by the present invention is to provide an absorbent article in which a reduction in liquid absorbency caused by the hydrophobicity of thermoplastic resin fiber is prevented through the use of thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component. The present invention solves this problem by providing a sanitary napkin provided with a top sheet, a back sheet, and an absorbent body disposed between the top sheet and the back sheet. The absorbent body has an absorbent material layer that contains a cellulose-based hydrophilic fiber and a thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component in a mass ratio of 90:10 to 50:50. The top sheet has an integrated section that is heat-treated together with the absorbent material layer so as to be integrated with the absorbent material layer.

Abstract: A method for packaging an absorbent article assembly that includes following the steps. First and second breast milk absorbent pads are fed onto wrapping sheet web. Next, the first breast milk absorbent pad is displaced from a transverse center line toward an upper end by ¼ of a dimension thereof as measured in a longitudinal direction, and the second breast milk absorbent pad is displaced from a transverse center line toward an lower end by ¼ of a dimension thereof as measured in a longitudinal direction. Next, the first and second breast milk absorbent pads are folded back from the upper and lower ends toward the transverse center line. Next, the upper and lower ends of the wrapping sheet web are folded back toward the transverse center line. Next, a joint zone is formed between the first and second breast milk absorbent pads and the pads are cut apart.

Abstract: A sanitary napkin provided with an absorbent body which includes a liquid permeable skin contact side sheet, a liquid impermeable non-skin contact side sheet, and an absorbent core which is arranged between these skin contact side sheet and non-skin contact side sheet and with a cover sheet which covers the surface of the skin contact side sheet. An individually wrapped product is formed by wrapping the napkin in the ready-to-wrap state by the wrapping material. The wrapping material includes a belt-shaped material which surrounds the ready-to-wrap napkin across the entire circumference of the ready-to-wrap napkin. A width of the belt-shaped material is shorter than a length of the ready-to-wrap napkin in the width direction of the belt-shaped material.

Abstract: A rotary working apparatus provided with a working unit and an actuator, wherein the working unit is provided with a unit frame and a cutter roll and anvil roll supported by the unit frame so as to be rotatable about mutually parallel axes of rotation, the anvil roll being further supported by the unit frame in a movable manner. The actuator is provided at the outside of the working unit and is provided with advanceable/retractable rods for making the anvil roll move to press the anvil roll against the cutter roll. A workpiece fed between the cutter roll and the anvil roll is worked by the rotating cutter roll and/or anvil roll.
