Abstract: A static apparatus includes an iron core which includes a plurality of magnetic plates stacked in one direction and in which a shaft portion having a main surface and a side surface is formed, and a coil wound around the shaft portion. Slits extending in an axial direction of the shaft portion are formed in at least a surface layer magnetic plate constituting the main surface, of the plurality of magnetic plates. Some of the slits are formed in the main surface, at an end portion close to the side surface, at a predetermined formation density. The formation density of the slits is highest at the predetermined formation density, and is reduced as at least one of a minimum distance from the side surface within the main surface and a distance from the main surface on a side close to the slits in the stacking direction is increased.

Abstract: A transformer includes a leg iron core including a plurality of magnetic sheets stacked in one direction (Z axis direction), and a coil wound around the leg iron core. A slit is formed in at least a magnetic sheet which faces an inner peripheral surface of the coil in a stacking direction of the plurality of magnetic sheets, of the plurality of magnetic sheets. Since eddy current is divided by the slit, eddy current density can be reduced. By reducing the eddy current density, loss density in an iron core can be reduced. By reducing the loss density in the iron core, loss in the transformer can be reduced.

Abstract: An independent two pump system comprising an implement hydraulic pump and a steering hydraulic pump is described. The system has an inexpensive structure and the capability of preventing a construction machine from engine stalling without impairing fuel economy. When the implement hydraulic pump is actuated with the output of an engine to operate an implement attached to the construction machine, while actuating the steering hydraulic pump with the output of the engine to turn a vehicle body of the machine, the load exerted on the implement is detected and if the detected load is determined to exceed a preset value, the displacement of the steering hydraulic pump is reduced to thereby reduce the load associated with turning of the vehicle body.
