摘要： The image recording method and apparatus are used to record an image formed by a group of light source elements disposed in a two-dimensional manner corresponding to recording pixels on a recording medium. In the image recording method and apparatus, an image recording position on the recording medium by the group of light source elements is moved in a direction that contains a component in at least one of two-dimensional disposing directions of the group of light source elements during the recording while modulating, in response to the movement, each recording pixel of the group of light source elements in accordance with an image to be recorded to thereby record the image on the recording medium. The image recording position is moved in accordance with a set magnification for changing the resolution par recording pixel of the group of light source elements. Further, the image recording position is moved by giving a relative speed difference between the relative movement of the group of light source elements and the recording medium and the tracking of the relative movement made by the image recording position by the group of light source elements.

摘要： The image recording method and image recording apparatus synchronize phase of a light deflector with rotation of a drum in response to the drum start point detection signal generated each time the drum rotates once, expose the two-dimensional image of one frame formed by a group of light sources disposed two-dimensionally onto the recording medium while causing the image at rest on the recording medium relatively thereto, thereafter move the optical system in the auxiliary scanning direction by an integral multiple of a pixel pitch forming one frame as well as deflect an angle of the light deflector in the main scanning direction by one frame so as to expose the next frame and on for one rotation of the drum. When the position is dislocated in the auxiliary scanning direction at the time the recording medium is to be exposed in a subsequent one rotation of the drum, the method and apparatus correct the dislocation of the position in the auxiliary scanning direction by changing an auxiliary scanning movement speed in a non-exposure time zone between the previous and subsequent rotations of the drum.Accordingly, the method and apparatus can prevent the occurrence of streaked unevenness in the surface exposure and spiral exposure.

摘要： A vehicle engine is coupled to a driving system that includes a torque converter and an automatic transmission. An ECU sets a target value of an opening degree of a throttle valve based on a depression degree of an acceleration pedal. The ECU changes the throttle opening degree at a predetermined gradual change speed such that the throttle opening degree reaches the set target value. The ECU limits the gradual change speed of the throttle opening degree for a predetermined period such that a changing speed of the engine speed is suppressed at a reverse time when a direction of torque transmitted between the driving system and the engine is reversed. As a result, shock produced when the direction of torque between the driving system and the engine is switched is suppressed.

摘要： A development processing apparatus including a pair of rollers for laminating a silver halide photosensitive material on which an image has been exposed and a processing sheet containing chemicals for forming an image on the silver halide photosensitive material; a heating plate having a curved heating surface for subjecting the silver halide photosensitive material to development processing by heating the silver halide photosensitive material and the processing sheet laminated by the pair of rollers; a transport belt for transporting the silver halide photosensitive material and the processing sheet laminated by the pair of rollers along the heating surface of the heating plate to allow the heating plate to effect the development processing; and a separation roller for separating the silver halide photosensitive material and the processing sheet after completion of the development processing by the heating plate. Accordingly, since processing solutions such as a developer and a fixer are not used for the development of the photosensitive material, the efficiency in maintaining the apparatus can be improved.

摘要： The improved color image forming apparatus comprises a rotating member for rotationally scanning and transporting both an image-receiving material having an image-receiving layer and a colorant sheet having a peelable, thin colorant film, a holder for holding at least the image-recieving material on the rotating member, a lamenator for pressing the colorant sheet so that it adheres to the image-receiving material, a recording device for applying thermal energy to the image-receiving material and the colorant sheet, and a peel/transfer mechanism by which the colorant sheet that has been imagewise supplied with thermal energy by the recording device is peeled for transfer to form a monochromatic image on the image-receiving material. This procedure of monochromatic image formation is repeated for three or four colors to produce a full color image. The apparatus is compact and yet is capable of forming high-quality image while assuring that the colorant sheet can be adhered to or peeled from the image-receiving material uniformly without causing failure in registration, particularly without causing unevenness during peeling.

摘要： An image formation device includes a matrix formation circuit, a pixel identification circuit, a binarization processing circuit, a halftone processing circuit, and a synthesizing circuit. The matrix formation circuit forms a data matrix window successively shifting. The pixel identification circuit determines whether an objective pixel is a binary or a halftone by determining whether each of the pixel signals in the data matrix window is a binary or a halftone. If the objective pixel is determined to be a binary, the binarization processing circuit processes the objective pixel signal. If the objective pixel is determined to be a halftone, the halftone processing circuit processes the objective pixel signal. These objective pixel signals are synthesized to form the image signal fed into a laser printing system.
