A framework capable of providing transparent handling of network traffic in close proximity networks such as home networks is provided. The present invention attains the object by providing an ambient temperature molten salt including a first imidazolium salt having a cationic segment represented by the general formula and an anionic segment represented by MX4 ; and a second salt having a cationic segment as a monovalent cation and an anionic segment as a halogen. The baffles help move the solid material toward the rotating toothed disk. The body opening includes a first elliptical half opening provided on the sliding top panel, and a second elliptical half opening provided on the fixed top panel. The cut out segment is rotatable from an article receiving position to an article bypass position. The thin film transistor array substrate may be used for an organic light-emitting display apparatus.
