摘要： An information processing system comprises a display apparatus having a display screen which can be held in position of either vertical elongation or lateral elongation. The information processing system provides the operator with messages necessary for operation. By detecting the position of elongation of the display screen, data for the messages are selectively rotated so as to be always displayed uprightly on the display screen.

摘要： It is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible. A stator (6) includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles (6a, 6b, 6c). The stator magnetic poles (6a, 6b, 6c) are each composed of an arcuate stator core (13) having a plurality of axially extending claw poles (16b) and a circumferentially elliptically wound stator winding (14). The stator magnetic poles (6a, 6b, 6c) are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles (6a, 6b, 6c) can improve a cooling effect.

摘要： An A.C. generator has a rotor that is equipped with a permanent magnet and a field coil. The output of the A.C. generator charges the high-voltage battery. Voltage of the high-voltage battery is stepped-down by a DC/DC converter and supplied to the low-voltage battery. When the motor controller detects that the field coil has not been energized, the higher-rank controller switches so as to generate power by means of the permanent magnet of the A.C. generator and charge the low-voltage battery. This mechanism enables power to be generated when a circuit malfunctions.Thereby, a power supply system for vehicle can generate power when a circuit malfunctions so that the driver on the vehicle can drive the vehicle to a repair shop.
