Abstract: An object of the present invention is to provide a method for producing high-purity 2,6-NDA having a small alkali metal content. The present invention relates to a method for producing a high-purity 2,6-naphthalene dicarboxylic acid, comprising a purification step of washing a crude 2,6-naphthalene dicarboxylic acid having a specific surface area of 2 m2/g or more in the presence of an aqueous medium under a temperature condition of 90° C. or more and less than 200° C.

Abstract: Provided is a support device configured to achieve space saving of an occupied area of a wall surface required for carrying out maintenance work. The support device includes a pair of support legs to be mounted to a housing of an electronic device to support the housing; a pair of fixing legs to be mounted to a mounting surface, at which the electronic device is to be installed, to fix the electronic device at a position at which the electronic device is to be installed; and a pair of slide hinge mechanisms configured to couple end portions of the pair of support legs to end portions of the pair of fixing legs in a manner in which the pair of support legs is pivotable with respect to the pair of fixing legs in an upright direction, and in a manner in which the pair of support legs is horizontally slidable with respect to the pair of fixing legs.

Abstract: Provided is a technology capable of reducing a surface area taken up on a wall surface and improving maintenance workability. A support device of this invention includes: a pair of support legs configured to be mounted to a side surface of a housing to support the housing; a pair of fixing legs configured to be mounted to a mounting surface at which the housing is to be installed to fix the housing at a position at which the housing is to be installed; and a movable mechanism configured to pivotably couple the pair of support legs and the pair of fixing legs.
