The present invention aims at providing an antistatic optical film having excellent antistatic effect and high light transmittance, wherein an antistatic layer laminated on at least one side of the optical film. An antistatic optical film having an antistatic layer laminated on at least one side of the optical film, wherein rubbing treatment is performed on a surface of the optical film on which the antistatic layer is laminated, and a conductive polymer in the antistatic layer is aligned.

Charge-preventing optical film, charge-preventing adhesive optical film, manufacturing method thereof, and image display device

Provided are a membrane filtering device managing system by which the membrane filtering device can be managed with a better precision and membrane filtering device for use therein, as well as to a membrane filtering device managing method. At least two sensors of an electric conductivity sensor, a flow rate sensor, and a pressure sensorare provided in at least two membrane elementsprovided in a membrane filtering device. A managing deviceobtains data from the at least two sensor, and compares the data with comparison data that represents a correlative relationship between a position along the axial line direction in the membrane filtering deviceand a standard value obtained from the at least two sensor. Accordingly, it is possible to specify the cause of change occurring in the membrane filtering devicemore definitely, and to carried out a suitable maintenance in accordance with the cause, so that the membrane filtering devicecan be managed with a higher precision.

Provided are a spiral type membrane element that can re-collect the electric power that is used in a good manner, and a spiral type membrane filtering device having the same. The spiral type membrane element comprises a power generating section that generates electric power by using a liquid, and an electric power outputting section that outputs, either in a wired manner or in a wireless manner, the electric power supplied from said power generating section. The electric power that is generated in the power generating section using the liquid (raw water, permeated water, or concentrated water) can be output from the electric power outputting section in a wired manner or in a wireless manner. Therefore, the electric power that is output from the aforesaid electric power outputting section can be used in an electric component disposed outside or can be stored into a capacitor section disposed outside.

A method for manufacturing a polarizing plate in which a transparent protective film is provided on at least one surface of a polarizer with an adhesive layer interposed therebetween, wherein an adhesive is coated on a surface of the transparent protective film on which the adhesive layer is formed or/and a surface of the polarizer on which the adhesive layer is formed to form the adhesive layers, and thereafter, an aqueous liquid is caused to be present on an adhering surface when the transparent protective film and the polarizer are continuously adhered to each other with the adhesive layer interposed therebetween. A polarizing plate having uniform polarization characteristics, and excellent in durability is obtained by the method.

Method for manufacturing polarizing plate, polarizing plate, optical film and image viewing display

A liquid crystal display comprising a liquid crystal display wide viewing angle polarizing adhesion film, which comprising a polarizing layer laminated on an optical compensation film and a retardation film and/or a brightness enhancement film laminated on said polarizing layer, wherein said polarizing layer is directly laminated on said optical compensation film, adhered onto at least one side of a liquid crystal panel, is less brightness nonuniformities.

Liquid crystal display wide viewing angle polarizing film and liquid crystal display wide viewing angle polarizing adhesive film

A spiral wound type membrane element is formed by superposing gas-liquid contact membranes on both surfaces of a first fluid passage forming member, superposing a second fluid passage forming member on the surface of one of the gas-liquid contact membranes and spirally winding the gas-liquid contact membranes around a second fluid supply pipe along with the first fluid passage forming member and the second fluid passage forming member. A side portion on the inner peripheral side and a side portion on the outer peripheral side of a first fluid passage formed by the first fluid passage forming member between the gas-liquid contact membranes are sealed. Both end portions of a second fluid passage formed by the second fluid passage forming member between the gas-liquid contact membranes are sealed. The spiral wound type membrane element is stored inside a cylindrical container. The gas-liquid contact membranes are formed by PTFE (polytetrafluoroethylene) porous membranes having hydrophobicity. First fluid is supplied from a first fluid inlet of the cylindrical container, passes through the first fluid passage of the spiral wound type membrane element and is taken outward from a first fluid outlet of the cylindrical container. Second fluid is supplied into the second fluid supply pipe from a second fluid inlet of the cylindrical container, passes through the second fluid passage of the spiral wound type membrane element and is taken outward from a second fluid outlet of the cylindrical container.
