Abstract: Ablation data of a region other than an image region, which ablation data is required for a positive-type printing plate, is added at a printing plate automatic exposure device side. Thus, a disadvantage of a time duration for transmission of job data from a PC being slowed because of the ablation data is solved. As a result, image recording operations can be made more efficient. Furthermore, the ablation data includes non-exposure portions at regions corresponding to peripheral edge portions of the printing plate. Consequently, light does not impinge on a leading end chuck, a trailing end chuck and the like, and the ablation data can be made suitable for interlaced scanning.

Abstract: A light amount adjustment method for use in an image exposure apparatus records an image by scanning a photosensitive material with a light beam modulated in accordance with image signal. The light beam has a first light amount level and a second light amount level that is higher than the first light amount level to perform exposure of one dot. The method sets the first light amount level based on the image signal, exposes test patches by displacing a focus position of the light beam on the photosensitive material and changing the second light amount level that is outputted in accordance with changing of the image signal and adjusts the second light amount level such that halftone dot percent fluctuations of the exposed test patches are minimized to set the adjusted second light amount level.

Abstract: There is provided a data transfer system capable of performing reliable data transfer while suppressing increases in costs. The data transfer system includes a data compressing apparatus and a data decompressing apparatus. The data compressing apparatus includes: a CPU which performs a compression process for applying compression to uncompressed electronic data to obtain compressed electronic data and performs a determination process for determining whether or not the compression process achieves predetermined targeted compression; and an output section which, only if the compression process achieves the predetermined targeted compression, outputs the compressed electronic data, and otherwise outputs uncompressed electronic data. The data decompressing apparatus includes a decompressing section which performs a decompression process only if electronic data received from the data compressing apparatus is compressed electronic data.

Abstract: A method and apparatus for recording an image by simultaneously recording a plurality of scanning lines by a plurality of laser beams. Image data are written sequentially in units of one scanning line into a plurality of memories. The image data of adjacent scanning lines are read simultaneously in order starting with a memory area corresponding to a leading end of the scanning line toward a memory area corresponding to a terminating end thereof. Laser beams are emitted on the basis of the image data read, so as to record the image. Since the plurality of items of image data are read simultaneously from the plurality of memories, the processing speed can be increased as compared with a case where image data are read sequentially from a memory.

Abstract: A microfilm retrieval system includes blip marks provided at transversely opposite side portions of selected image frames of an elongated microfilm, a device for detecting the blip marks, counters for counting the number of blip marks in accordance with kinds of blip marks, respectively, a device for determining a specific combination of the kinds of blip marks when two or more kinds of blip marks are provided to selected the image frames, and a controller for controlling the counters such that the blip marks are counted with a unit of count and a reset value corresponding to the specific combination of marks determined by the determining device. The unit of count and the reset value at the time of counting blip marks can be set to desired numerical values, and counting is effected by making a page number or the like provided on a photographed object coincide with a count value, thereby facilitating retrieval.

Abstract: The present invention relates to an elevator group control method of controlling a plurality of elevator cars servicing for a plurality of floors, including the steps of applying fuzzy rule groups to a hall call when such a call occurs, and selecting an optimum elevator car with a fuzzy inference applied, and assigning a call to the car. A plurality of fuzzy rule groups are successively applied according to respective priority orders previously given to the fuzzy rule groups. In such successive application, only when there is at least one car, excluding the car whose assignment aptitude is optimum, which has the difference in the assignment aptitude value for the current rule group, from that of an optimum car, of not greater than a predetermined threshold value, a subsequent rule group is applied.

Abstract: Disclosed is a synchronizing circuit for an optical scanning apparatus in which synchronization of writing of an image in the horizontal direction is achieved using a synchronizing signal generated in response to the output signal of an photo sensor for detecting the light which has passed through a scanning means. The synchronizing circuit includes a frequency dividing circuit for dividing the frequency of a clock pulse train having a predetermined frequency in response to the output signal from the photo sensor, a delay circuit for successively delaying the phase of the frequency divided clock pulse train by a predetermined time interval when it produces output signals, and a selecting circuit for selecting as a synchronizing signal the output of the delay circuit whose phase difference is at a minimum with respect to the output of the photo sensor.
