摘要： An external memory control device which is capable of reducing the time required for processings such as write and read of data for the storage areas of an external memory device, such as a disk, is disclosed. The external memory control device includes a smallest sector number register and a largest sector number register which store the smallest and the largest sector numbers, respectively, within a processing range on a track that is designated by a processing request signal frokm a central processing unit, and a processing range detecting part which detects whether a sector number read from the designated track is within the processing range. In this external memory control device, if the sector number read from the designated track is within the processing range, the processings start from the next sector, so that waiting until the arrival of the smallest sector number is no longer needed, and the time required for processing per track can be reduced.

摘要： A driving power control device for a hybrid vehicle controls the engagement state of a lockup clutch so that high efficiency in regeneration is obtainable. The driving power control device for a hybrid vehicle includes an engine and a motor-generator as power sources, an automatic transmission disposed between the power sources and driving wheels with an intervening torque converter having a lockup clutch, and an ECU for controlling selection of the power sources and for controlling a slip ratio of the torque converter. In this control device, a target slip ratio of the torque converter, which corresponds to a target amount of regeneration that is retrieved using regeneration amount determining factors, is obtained by executing a feedforward control operation using friction torque determining factors, and the slip ratio is controlled in a feedback manner based on the difference between the target slip ratio and the actual slip ratio.

摘要： A multi-beam scanning optical system includes a plurality of light sources, a deflecting unit which deflects a plurality of laser beams emitted from the light sources, and a scanning optical unit which focuses the laser beams deflected by the deflecting unit onto the surface of a photosensitive member. The scanning optical unit is set such that lateral chromatic aberration is overcorrected. In addition, among angles formed between each laser beam incident on the surface of the photosensitive member and the normal at the surface of the photosensitive member in a sub-scanning direction, the oscillation wavelength of the light source that emits a laser beam forming the minimum angle is set to a value smaller than the oscillation wavelength of the light source that emits a laser beam forming the maximum angle.

摘要： The tractor-feed unit has a pair of first and a pair of second rollers rotatably supported by frame members. A pair of endless tractor belts are wound around the first and second pair of rollers. The tractor belt has protrusions, with which sprocket holes formed in a continuous sheet are engaged. A central portion of each of the frame members is bent to form a guide member, which is engaged with an upper and peripheral edge of a tractor belt, so that a tractor belt is deflected downward. Thus, the protrusions are separated from the sprocket holes to a position, corresponding to a guide member, below the continuous sheet.
