A fluid handling device including an eaves section of a first side wall engaged with a recess of a strip plate including a plurality of wells using concavity and convexity and an eaves section of a second side wall engaged with a recess of the strip plate using concavity and convexity. The dispersant has a multifunctional head that comprises an acidic group, a basic group and an aromatic group, thereby enhancing an affinity for the surface of phosphor particles and improving dispersibility. Then, of end portions of the island semiconductor regions, at least a portion used to form a channel of a thin film transistor, or a portion that a gate electrode crosses is etched, so that a region that the distortion is accumulated is removed. As such, the tube of the present invention may be useful as a manufacturing aid, as a deployment sheath, and in other applications that may benefit from easier tubular sheath removal. The electronic check out system includes readers located a tool boxes and the central storage facility exit to identify the tool and the user of the tool as well as the time and date the tool was removed from the storage facility.
