The neutral points are arranged on one side of the windings 31 to follow the periphery of the stator 11.

Abstract: In a system for dehydrating carbon dioxide gas, the carbon dioxide gas is cooled by using a turbo expander (21), and the power extracted by the turbo expander from the carbon dioxide gas is used in the system for compressing the carbon dioxide gas. The cooled carbon dioxide gas is fed to a knock-out drum (22) to remove free water therefrom. The carbon dioxide gas from the separator is introduced to a secondary dehydration unit (11) and recompressed to the required pressure for carbon storage or for EOR operation.

Abstract: An electric vehicle includes a wire harness that flexibly follows the swinging of the swing arm, surely avoids any contact with other components, and has excellent durability. The electric vehicle includes a battery mounted to a frame, an inverter and an electric motor accommodated in a swing arm, and a wire harness wired between the frame and the swing arm. The swing arm includes a hollow pivot section, and a partition wall partitioning the pivot section and an arm section. The wire harness suspends from the frame side, enters inside the pivot section from the top face side of the pivot section, and is bent inside the pivot section reaching the inverter through the partition-wall through port.
