Abstract: A rotating electrical machine includes an annular coil connection body provided coaxially with a stator. The coil connection body has, in a groove provided on a holder, an overhang portion for restricting an axial-direction movement of a terminal, and a positioning projection for restricting a radial-direction movement of the terminal. The positioning projection positions the terminal such that a part of the terminal overlaps the overhang portion in the axial direction. In this structure, when the terminal moves in a direction from a terminal holding portion toward a groove opening, the terminal comes into contact with a side surface of the overhang portion, whereby lifting and coming-off of the terminal can be prevented.

Abstract: A sheet processing apparatus includes a processing unit, a sheet discharge unit, a determination unit, and a control unit. The processing unit performs crease processing on a sheet. The sheet discharge unit discharges a sheet having been subjected to the crease processing by the processing unit. The determination unit determines whether a number of the discharged sheets having been subjected to the crease processing exceeds a predetermined number of sheets. The control unit performs control to cause the discharge unit to discharge a sheet. In a case where the determination unit determines that the number of the discharged sheets having been subjected to the crease processing exceeds the predetermined number of sheets, the control unit performs control to cause the discharge unit to not discharge sheets having been subjected to the crease processing onto the discharge destination.

Abstract: A fuel cell system which prevents the deterioration of the fuel cell stack when feeding of the oxidant gas is paused under a load to perform a fuel conservation operation. Controller shuts down oxidant gas compressor and cooling water circulating pump to execute fuel conservation operation at a low fuel cell system load. The controller gives a current draw instruction to electric power controller. In the fuel conservation operation, electric power controller draws a current larger than zero from fuel cell stack, and keeps the total charge drawn per unit time constant or substantially constant.
