摘要:
A scanning optical device that includes a laser source that emits a laser beam; a deflector for deflecting a laser beam to form a scanning beam spot on an image surface; a beam splitter, between the laser source and the deflector, and a sensor positioned in a predetermined position relative to the beam splitter. In particular, the beam splitter includes a reflective area in which the laser beam from the laser source is reflected and a transmitting area that is distinct from the reflective area through which the laser beam is transmitted. One of the reflected laser beam or transmitted laser beam is a main beam to be deflected by the deflector and the other is a monitor beam to be detected by the sensor.

A scanning optical device that includes a light source that emits a light flux; a polygon mirror for deflecting the light flux; a scanning lens for converging the light flux deflected by the polygon mirror to form a beam spot on an image surface; a dynamic prism that is rotatably disposed between the light source and the polygon mirror to affect the direction of the light flux; a driving mechanism for rotating the dynamic prism to change the deviation angle of the dynamic prism; and a controller for controlling the driving mechanism to change the position of the beam spot during scanning. In particular, the controller rotates the dynamic prism to compensate for errors that affect the position of the beam spot on the image surface, such as errors that vary with time and errors that occur randomly during the scanning process.

On one side of a valve shaft, there are provided an accelerator drum connected to an accelerator pedal by an accelerator wire, a return spring for urging the accelerator drum in a valve closing direction, and an accelerator sensor for detecting rotation of the accelerator drum and transmitting a detected signal to a host system. On the other side of the valve shaft, there are provided a large-diameter gear and an opening sensor. An armature of a solenoid clutch is attached to the gear and held on a motor shaft via a slide bearing. Thus, the motor, the solenoid clutch and the throttle valve are arranged into a U-shaped form for interconnection through four gears.

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.

It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.

An AC generator comprises a rotor and a stator having a three-phase winding. A three-phase inverter is connected to the three-phase winding. Here, the three-phase winding comprises at least two independent three-phase windings. Switching elements for respective phases of the three-phase inverter are connected in parallel by the number of the independent three-phase windings, and in-phase windings are individually connected to their parallel switching elements.
