Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

Abstract: A power supply unit for converting AC power into DC power and a battery unit for converting power stored in a battery into DC power and outputting the same are both accommodated in one shelf to form an uninterruptible power supply device, and the DC output terminals of the power supply unit and the DC output terminals of the battery unit are connected in parallel within the shelf by a connection conductor module that holds a connection conductor therein. The connection conductor module is composed of a module case formed from an insulating material and an electrically conductive connection conductor.
