Abstract: The invention provides a radiation intensity measuring apparatus for each of small sealed radiation sources for cancer therapy that is capable of measuring multiple cartridges. The apparatus includes a device for setting up multiple cartridges and a device for measuring the radiation intensities of radiation passing through a narrow slit. Radiation is emitted from multiple radiation sources and the radiation measurement device moves simultaneously together with the slit along with the side of cartridge holding device while scanning the radiation intensities. Included is a radiation detection scanning device for measuring radiation intensities for each of the radiation sources passing through the narrow slit, and a slit shielding system for restricting radiation originated originating from both the side neighboring radiation sources.

Abstract: Provided is a radiation intensity measuring apparatus for each of small sealed radiation sources for cancer therapy capable of measuring multiple cartridges efficiently and rapidly.

Abstract: Provided are an absorbent and an absorptive article containing the absorbent which has excellent water absorbability and leakage prevention ability, and has an intent to achieve reductions in the weight and thickness of an absorptive article. The absorbent comprises a polysaccharide that causes a gelation reaction in the presence of a polyvalent metal ion and a source of the polyvalent ion, in which the polyvalent ion is supplied simultaneously with or after dissolution and swelling of the polysaccharide. The absorptive article containing the absorbent can achieve excellent water absorbability and leakage prevention ability and thus reductions in the weight and thickness as the absorptive article.

Abstract: A cleaning structure for removing dust is constituted of a guiding member having a sliding surface for guiding run of a tape, and a vacuum pressure supply source for making a vacuum pressure effect on a suction space provided inside the guiding member and so on. At the sliding surface of the guiding member, a suction port for making the suction space communicate with an external space is formed, and the opening edge of the suction port on the downstream side in the tape running direction is served as a first dust removal portion for removing dust on the tape surface. The guiding member has a guiding wall having a contact surface which guides at least one tape edge of a tape, and the contact surface is served as a second dust removal portion for removing dust adhering to the tape edge.

Abstract: A water-absorbent structure comprises an assembly of thermoplastic synthetic fibers, cellulose-based fibers, super-absorbent polymer and water-pervious sheets wrapping these components together. The assembly is a honeycomb construction having a plurality of through-holes and normally in a compressed state. Upon water permeation into the water-absorbent structure, the super-absorbent polymer is swollen and softened and the assembly is swollen so that the through-holes restore the initial state before the assembly has been compressed.

Abstract: Disclosed is a water disintegratable sheet including bast/leaf fibers and at least one kind of primary fibers. The bast/leaf fibers have a Canadian Standard freeness value of at most 600 milliliter and occupy 2 to 75% by weight of a total fiber weight of the sheet.

Abstract: Disclosed is a water disintegratable sheet of which fibers are hydroentangled about each other. The water disintegratable sheet includes: at least one kind of primary fibers having a fiber length of at most 10 millimeter; and bast/leaf fibers having a Canadian Standard freeness value of at most 600 milliliter and a fiber length of at most 10 millimeter.

Abstract: A disposable diaper includes a pair of tape fasteners 6 that are used to connect front and rear waist regions 8, 10 to each other and are attached to side flaps 14 in the rear waist region 10 of the diaper. Each of the tape fasteners 6 includes fibrous nonwoven fabric made of thermoplastic synthetic resin fiber and thermoplastic synthetic resin coated on a substantially whole area of an outer surface of the fibrous nonwoven fabric wherein the thermoplastic synthetic resin forms a substantially smooth synthetic resin layer on outer surfaces of the respective tape fasteners. Thus, a free portion of each tape fastener is reliably prevented from being disengaged from a target tape even when the outer surface of the tape fastener and an inner surface of an underwear rub together during use of the diaper.

Abstract: An indicator interposed between a liquid-impervious sheet and an absorbent core of a body fluid absorbent article includes a water-absorbent sheet and indication elements held in close contact with the water-absorbent sheet. The water-absorbent sheet is preferably formed from porous thermoplastic films having a total luminous transmittance of 40% or lower in a dry state and 60% or higher in a wet state.

Abstract: A disposable diaper is improved so that a free portion of each tape fastener is reliably prevented from being disengaged from a target tape even an outer surface of the tape fastener and an inner surface of an underwear rub together during use of the diaper. A pair of tape fasteners 6 used to connect front and rear waist regions 8, 10 to each other are attached to side flaps 14 in a rear waist region 10 of a diaper 1A, respectively. In the diaper 1A, each of the tape fasteners 6 including first fibrous nonwoven fabric made of thermoplastic synthetic resin fiber and thermoplastic synthetic resin coated on a substantially whole area of an outer surface of the first fibrous nonwoven fabric wherein the thermoplastic synthetic resin forms a substantially smooth first synthetic resin layer on outer surfaces of the respective tape fasteners.

Abstract: A topsheet for a disposable wearing article that is formed with a plurality of fine openings each having an area of about 0.16-5 mm2 and a part of the peripheral edge of each opening is protuberated upward from an upper surface of the topsheet. The topsheet is thereby improved so that body fluids can be rapidly absorbed and stuffiness as well as eruption of the wearer's skin can be reliably avoided.

Abstract: A disposable body fluid absorbent wearing article includes a liquid-pervious topsheet including plastic film layer sections, liquid-pervious openings and a first fibrous layer bonded to the lower surface of the film layer sections. A second fibrous layer forming a liquid-absorbent core is contiguous to the lower surface of a first fibrous layer and a third fibrous layer is contiguous to the lower surface of the second fibrous layer. The wearing article is constructed so that its Klemm's water absorbency may progressively increase in the order of the first fibrous layer, the second fibrous layer and the third fibrous layer.
