Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

Abstract: The present invention is to provide a material that is capable of selectively adsorbing organic fluoro-compounds such as perfluorooctane sulfonic acid, allows the adsorbed organic fluoro-compounds to be recovered, and is reusable as an adsorbent, specifically to provide a polymer in which cyclodextrin is supported on the surface of a water-insoluble polymer, and an adsorbent containing the same, and a method of use of the same as a selective adsorbent of, in particular, an organic fluoro-compound.

Abstract: Disclosed are an adsorption process whereby a fluorocarboxylic acid having an ether bond can be adsorbed to a high extent by using active carbon without changing the form thereof, and a desorption process whereby the adsorbed material can be desorbed from the active carbon to thereby enable the reuse of the active carbon and the adsorbed material. In the aforesaid processes, a solution containing a fluorocarboxylic acid having an ether bond is contacted with active carbon and thus the active carbon is allowed to adsorb the fluorocarboxylic acid, to thereby give a solution having a small fluorocarboxylic acid content. Then, the active carbon having adsorbed the fluorocarboxylic acid is heated to thereby desorbs the fluorocarboxylic acid from the active carbon.

Abstract: An adsorption process in which high adsorption of C2-C6 fluorine-containing compound can be attained without any morphological change thereof by the use of active carbon; and a desorption process in which active carbon and adsorbed substances can be recycled by desorption from active carbon. A liquid containing the C2-C6 fluorine-containing compound is brought into contact with active carbon to thereby cause the active carbon to adsorb the fluorine-containing compound and thus obtain a liquid of low fluorine-containing compound content. The active carbon having the adsorbed fluorine-containing compound is heated so as to desorb the fluorine-containing compound from the active carbon.
