A method of making a self-sealing membrane for a prosthetic implant includes applying tension to a first layer of a cured elastomeric material to stretch the first layer, and while the first layer remains stretched, applying a second layer of an uncured elastomeric material over a first major surface of the first layer. After the second layer is cured, the tension on the first layer is released, whereupon the first layer returns to a non-stretched configuration for holding the second layer in contraction. The method includes, while the first layer remains stretched, applying a third layer of an uncured elastomeric material over a second major surface of the first layer. After curing the second and third layers, tension is released from the first layer, which returns to the non-stretched configuration for holding the second and third layers in contraction.

Provided is a beauty care pack including: a support; and a membrane that is laminated on the support so as to be separated by moisture, formed by electrospinning a polymer material, a water-soluble polymer material and a functional material, and a dry type, in which the functional material is dissolved by moisture, to thereby enable an easy and convenient storage and package, and enable a convenient use since a dry sheet is attached to the face.

A method includes applying a transferrable material to an outer surface of a casting plate to form a pattern on the outer surface of the casting plate. After applying of the transferrable material, a composite material is applied to the outer surface of the casting plate to form an inflatable membrane. The composite material covers at least a portion of the pattern and includes a florescent material and a pigment material. The inflatable membrane is cured to allow removal of the inflatable membrane from the casting plate. The inflatable membrane has an inner surface having the pattern detectable upon receiving of light causing the fluorescing material to emit florescent light.

A composite membrane, a biosensor, and preparation methods thereof are disclosed. In the preparation process, a moldable and plastic material is used as a carrier; after a dispersion liquid of a nanocarbon material wets the carrier, by means of multiple stretching and folding processes, the nanocarbon material is uniformly distributed and arranged regularly inside the entire plastic material in a stretching strain direction. The prepared composite membrane is elastic, attachable, and cost-efficient, and may detect strains as high as 530%. The composite membrane further has high sensitivity and high durability, and may be effectively applied to a biosensor for monitoring motion and humidity.

A method of manufacturing an all-solid-state battery and an apparatus for manufacturing the same are provided. The method of manufacturing the all-solid-state battery includes: (a) a step of forming a non-woven fabric having a fiber made of a resin; (b) a step of applying a slurry containing solid electrolyte particles onto the non-woven fabric; (c) a step of drying the slurry on the non-woven fabric by a heater; (d) a step of pressurizing the slurry on the non-woven fabric by a roller; (e) a step of forming a positive electrode member on one surface of the solid electrolyte membrane; and (f) a step of forming a negative electrode member on the other surface of the solid electrolyte membrane. The step (a) is a step of forming the non-woven fabric by making a resin containing a polar filler fibrous by a laser electrospinning method. By such a method, the all-solid-state battery (a laminated body of a positive electrode member, a solid electrolyte membrane, and a negative electrode member) can be efficiently manufactured.

The present invention relates to a folded side-leakage-proof arc-shaped elastic sanitary product wainscot and a production line therefor. After two sides of an elastic membrane under a tensile state are compounded with nonwoven fabric strips by hot pressing respectively, the elastic membrane rebounds and resets to impel the nonwoven fabric strips located on two sides of the elastic membrane to form a folded side-leakage-proof side wall. The elastic membrane is in the shape of a concave arc. The present invention has the following advantages: 1, the nonwoven fabric strips may be compounded with two sides of the elastic air-permeable membrane without a hot melt adhesive so as to ensure that the air permeability of the elastic air-permeable membrane and the nonwoven fabric strips is not affected by the hot melt adhesive; and 2, after two sides of the elastic air-permeable membrane under a tensile state are compounded with the nonwoven fabric strips, the elastic air-permeable membrane rebounds to impel the nonwoven fabric strips to form a required elastic folded side-leakage-proof side wall with the rebound and reset of the elastic air-permeable membrane. This side wall not only has a function of preventing liquid from flowing, but also greatly reduces a contact area between a sanitary napkin or a panty-shape diaper and a human body, such that the comfort level of the human body is greatly improved.

A mixed powder and a material for molding have polytetrafluoroethylene as a main component. Each includes polytetrafluoroethylene that can be fibrillated, a non-hot melt processable component that is not fibrillated, and a hot melt processable component with a melting point of lower than 320 C. that is not fibrillated. The non-hot melt processable component that is not fibrillated is contained in a range of 20 to 40% by weight of the total weight. The hot melt processable component is contained at equal to or more than 0.1% by weight but less than 20% by weight of the total weight. A drawn porous body includes a plurality of fibrils, and a plurality of knotted portions that are connected to each other by the fibrils.

A polyolefin microporous membrane includes a polyethylene composition, and 0.5% or more but less than 5% by mass of polypropylene, wherein the polyethylene composition includes polyethylene having a mass average molecular weight of 2.510.sup.5 to 510.sup.5 and ultrahigh molecular weight polyethylene having a mass average molecular weight of 110.sup.6 to 310.sup.6 in an amount of more than 5% by mass and not more than 50% by mass based on 100% by mass of polyethylene composition and has a molecular weight distribution (Mw/Mn) of 5.0 to 300, and the polyolefin microporous membrane has an injection of electrolyte of 20 seconds or less and a uniform polypropylene distribution in at least one plane perpendicular to the thickness direction.

An orifice plate having orifice openings is interposed between a roller body and a side plate. In a closed region of an outer peripheral surface of the roller body which is covered with a base material, the base material is held on the outer peripheral surface of the roller body under suction by a negative pressure developed in suction holes. In an open region of the outer peripheral surface which is not covered with the base material, the sucking of a gas from an exterior space into the roller body is suppressed because it is difficult for the gas to pass through the orifice openings. This suppresses a reduction in sucking force in the closed region due to the entry of the gas from the open region. The roller body, the orifice plate and the side plate rotate as a unit. This suppresses deterioration of the members due to the slidable movement thereof.
