A stator comprises: a stator core having a plurality of slots; and a cage coil formed of a rectangular combined conductor that is wound by a plurality of turns. The tunnel junction region includes a first semiconductor layer of a first conductive type and a second semiconductor layer of a second conductive type that forms a junction with the first semiconductor layer, the first semiconductor layer being composed of a supper-lattice layer that at least partially includes aluminum and is partially oxidized. A unique list view through which IOs can be displayed and managed is also disclosed. Also, the computer system may determine a first bin selected from a plurality of non-reserved product bins that is associated with product units of the non-reserved product and generate a pick instruction specifying the first bin and the unit quantity of the non-reserved product specified by the order. The sleeve also defines a plenum surrounding the drill shaft to communicate pressurized fluid to the fluid jet throughout longitudinal and rotational displacement of the drill shaft. By this, the deterioration of carrier mobility is prevented and a metal-oxide-semiconductor field-effect transistor is obtained.
