Abstract: The present invention provides a gas separation system suitable for separating a gas mixture efficiently. A gas separation system of the present invention includes: a first separation membrane that separates a gas mixture into a first permeated gas and a first non-permeated gas; and a second separation membrane that separates the first non-permeated gas into a second permeated gas and a second non-permeated gas. The gas mixture contains a gas A and a gas B different from the gas A. The first separation membrane allows the gas A to preferentially permeate therethrough. The second separation membrane allows the gas B to preferentially permeate therethrough. A membrane area of the first separation membrane is smaller than a membrane area of the second separation membrane. The gas separation system recovers each of the second permeated gas and the second non-permeated gas.

Abstract: The present invention provides a method for manufacturing a separation membrane suitable for transferring a separation functional layer and an intermediate layer from a release liner to a porous support member. The manufacturing method of the present invention is a method for manufacturing a separation membrane 10 including a separation functional layer 1, a porous support member 3, and an intermediate layer 2. The manufacturing method includes: forming the intermediate layer 2 on a first laminate 15 having a release liner 5 and the separation functional layer 1; bonding the intermediate layer 2 of a second laminate 16 having the release liner 5, the separation functional layer 1, and the intermediate layer 2 in this order to the porous support member 3 and thereby forming a third laminate 17; and removing the release liner 5 from the third laminate 17. In the manufacturing method, the intermediate layer 2 is formed in such a manner that a ratio R of an adhesive strength A2 (N/50 mm) between the intermediate layer 2 and the porous support member 3 with respect to an adhesive strength A1 (N/50 mm) between the release liner 5 and the separation functional layer 1 is 3.1 or more.

Abstract: An object of the present invention is to provide a transparent adhesive film which is hardly visually recognized, that is, inconspicuous, and thereby has little influence on design properties of an adherend. The present invention relates to a transparent adhesive film including: a base material having an uneven surface; and an adhesive layer laminated on a surface of the base material on a side opposite to the uneven surface, in which a mean spacing Sm of an unevenness on the uneven surface of the base material is 45 μm or more, an average tilt angle θa of the unevenness on the uneven surface of the base material is 0.5° to 15°, and a 60-degree glossiness GL on the uneven surface of the base material is 60% or less.

Abstract: Provided is an adhesive member to be adhesively fixed through pressure which has both position adjustability and adhesiveness and is capable of producing a sufficient adhesive strength in addition to the position adjustability. The adhesive member comprises a support, a pressure-sensitive adhesive layer provided on one surface of the support, and a plurality of protrusion elements arranged, in spaced-apart relation to each other, on a principal surface of the pressure-sensitive adhesive layer on a side opposite to the support. Each of the protrusion elements is composed of an aggregation of a plurality of cohesive particles, wherein the adhesive member has a frictional force of 0.4 N/cm2 or less, with respect to a stainless steel plate serving as an adherend, as measured when the protrusion elements are in contact with a surface of the adherend, and a shear adhesive strength of 45 N/cm2 or more.
