Abstract: [Summary] [Problem to be Solved] To construct a management server that can provide video and audio according to the position, where a camera films, to user terminals. [Solution] It is configured that a management server comprises a camera extraction section receiving a desired camera from a user terminal, an audio extraction section receiving audio generation data from a distributor terminal, a video extraction section receiving video generation data corresponding to a filming subject from the distributor terminal, a distribution audio generation section generating distribution audio to be distributed to the user terminal, a video generation section generating distribution video to be distributed to the user terminal based on the video of the filming subject and the distribution audio.

Abstract: A material for gas separation obtained by mixing a copper compound and a benzoin and/or an ascorbic acid in a solvent.

Abstract: A gas separation membrane using, as the material for the membrane, a polymer having the main repeating unit of the formula: ##STR1## and/or formula: ##STR2## (where R represents alkyl group, vinyl group, allyl group, cycloalkyl group, aryl group, benzyl group or hydrogen atom, each R being possibly identical or different to each other) and having the number average molecular weight of between 1,000-1,000,000, or a partially or wholly hydrogenated product of said polymer with the unsaturation bonds therein.

Abstract: In a foodstuff container of the type comprising a cylindrical body of a laminated sheet and lids closing the opposite ends of the cylindrical body, the laminated sheet is made up of two outer layers made of a thermoplastic resin consisting essentially of a synthetic resin having a melting point higher than 115.degree. C., a paper layer and an aluminum foil. The opposite side edges of the laminated sheet are covered by tape shaped aluminum foils with both surfaces coated with a thermoplastic resin similar to that of the laminated sheet, and one ends of both of the tape shaped aluminum foils are bent back to face the inner surface of the container. The tape shaped aluminum foils and the opposite side edges of the laminated sheet are welded together to form the cylindrical body.
