摘要： A scanning optical system deflects a light beam by a reflection surface of a polygon mirror toward an object surface through an image forming optical system so that the light beam scans on the object surface to form an image thereon. A light shielding member is disposed between the polygon mirror and the image forming optical system. The shielding member is an opaque plate disposed perpendicular to the optical axis of the image forming optical system. The light shielding member prevents a ghost light that is reflected by another reflection surface of the polygon mirror located adjacent to the reflection surface deflecting the light beam from entering the image forming optical system and impinging onto the object surface.

摘要： A hybrid compressor system affords maximum cooling capability by making full use of an additional motor to improve the fuel consumption efficiency of a vehicle while ensuring passenger compartment cooling when the engine is stopped. The hybrid compressor system includes a compression unit for compressing a refrigerant, a motor for driving the compression unit, and disconnection means for disconnecting the drive force of a vehicle engine. In the hybrid compressor system, when the thermal load of the refrigeration cycle system lies within a predetermined range in a higher load region, the control means connects the disconnection means to allow the vehicle engine to drive the compression unit. When the thermal load of the refrigeration cycle system lies within a lower load region of the predetermined range, the control means disconnects the disconnection means to allow the motor to drive the compression unit even while the vehicle engine is running.

摘要： An air-conditioner for use in an automotive vehicle, an engine of which is stopped every time the vehicle stops at an intersection, includes a usual refrigeration cycle having a main compressor driven by the engine and a sub-circuit having a sub-compressor driven by an electric motor. The sub-compressor is connected in parallel to the main compressor, and both compressors are alternately driven. Refrigerant mixed with lubricant circulating in the main refrigeration cycle is prevented from entering into the sub-circuit while the sub-compressor is not in operation by means of a piping structure of the sub-circuit. When the refrigerant enters into the sub-circuit, it is efficiently returned to the main refrigeration cycle by intermittently operating the sub-compressor while the main compressor is operating.
