摘要： A surface treatment method improves the surface properties of a metal member while maintaining the metal surface texture, and a metal member is obtained by the surface treatment method. The surface-treated metal member is obtained by bringing a solution of a fluorine-based polymer into contact with a surface of an anodic oxidation coating that is formed on a surface of a metal and has not been subjected to a sealing treatment, and subjecting the anodic oxidation coating to a steam sealing treatment, the surface-treated metal member comprising a fluorine-based polymer layer having a thickness of 100 nm or less, and a composite sealed layer that is formed continuously under the fluorine-based polymer layer, the composite sealed layer having a configuration in which the fluorine-based polymer is present inside pores formed in the anodic oxidation coating.

摘要： A multipurpose arena with a suspended roof and an interior which can be adjusted to accommodate events requiring different space arrangements. The roof is made of sections suspended between opposed supporting pylons and assumes a catenary shape. Rail-mounted, motor-driven, stands can be shifted from place to place depending on the event or events being catered. Partitions divide the arena into separate private compartments wherein separate events can be held simultaneously in each compartment.
