Abstract: As shown in FIG. 1, a biosensor according to the present invention is provided with an area in which a reagent having bleaching action is carried in a state where it can be dissolved, at least in a part of a sample application area to which an inspection target solution is applied or the downstream of the sample application area in the direction of the inspection target solution permeating, in a development layer.

Abstract: A chromatography specimen 10 according to the present invention has a sample application part 2 to which a liquid sample is applied; a marker hold region 3 which holds a marker reagent; a reactive layer 4 where a binding reaction between the marker reagent and an analysis target is processed; a specific protein immobilization part 5 in which a specific protein is held in the area of the reactive layer 4; and a water-absorbing part 6 for absorbing a sample, and the reactive layer 4 is impregnated with a surface active agent dissolved solution having such a property that it can be solidified when dried and thereafter subjected to a drying processing.

Abstract: A substantial amount of a marker reagent associated with measurement is measured in an marker reagent measurement area 6, and the substantial amount of the marker reagent is reflected by a result obtained in an reaction result measurement area 7 where a reaction with a measurement target in an inspection target solution is measured.

Abstract: According to the biosensor and the blood component analytical method of the present invention, in a biosensor that is made of a single layer or plural layers of a porous material as shown in FIG. 1, having a reagent holding part and utilizing chromatography, a cell shrinkage reagent is carried on at least part of the reagent holding part, or at least part of a chromatographically developed part that is upstream of the reagent holding part.

Abstract: A biosensor which is provided with a development layer (2) for developing an inspection target solution, that has a reagent immobilization part (5) where an antibody for a measurement target in the inspection target solution is immobilized and a reagent holding part (4) which marks in a dry state and holds an antibody which can be eluted by development of the inspection target solution in parts of the development layer (2), and measures a bonding amount of the marker reagent bonded to the reagent immobilization part (5), thereby qualitatively or quantitatively measuring components to be measured in the inspection target solution, is further provided with a space forming material (8) that forms a cavity part (1), which is a space into which the inspection target solution flows, between the development layer (2) for developing the inspection target solution and the space forming material (8).

Abstract: A charging member comprising a conductive mandrel, a semiconductive foamed elastic layer provided on the periphery of the mandrel, and a functional double-layer film provided on the periphery of the semiconductive foamed elastic layer. The semiconductive foamed elastic layer is a layer formed by making the mandrel and a semiconductive rubber composition standing uncured and unfoamed pass through a crosshead die of an extruder to set the composition on the periphery of the mandrel, followed by curing and foaming. The semiconductive rubber composition has a Mooney viscosity of from 15 to 30 and having a curing percentage of 40% or less when the foaming pressure reaches 50%. The functional double-layer film is a double-layer tube having a thin layer such that a tube formed out of only the layer is hard to use for covering. Also disclosed are a process cartridge and an electrophotographic apparatus which have such a charging member.

Abstract: A disposable diaper having an excellent fit to the wearer has an outer member (2) having front and back waist sections (4, 5) and crotch sections (6), and a liquid absorbent member (3), wherein the outer member includes an outermost sheet layer (21) and a pair of side liner sheet layers (22), and the liquid absorbent member includes a liquid non-permeable back sheet layer (13), a liquid permeable top sheet layer (14) and a liquid absorbent pad layer (15) interposed between the back and top sheet layers, each side liner sheet layer being formed from a composite sheet including an elastic sheet ply capable of expansion and contraction in the transversal direction of the diaper and at least one non-elastic sheet ply laminated on at least one surface of the elastic sheet ply and capable of elongation in the transversal direction of the diaper.
