摘要： A fluorescent X-ray analyzing apparatus capable of being used as either a wavelength dispersive type or an energy dispersive type is provided, with which the analysis can be performed quickly and accurately. The fluorescent X-ray analyzing apparatus includes a detecting unit for detecting and analyzing fluorescent X-ray (5) emitted from at least one target area (1a) of a sample (1) to be analyzed as a result of excitation of such target area (1a) with a primary X-ray (3). The detecting unit includes a wavelength dispersive type detecting unit (6) including a spectroscope (8) and a first detector (9), and an energy dispersive type detecting unit (11) including a second detector (12) of an energy dispersive type. The angle &thgr;1 formed between a first path (81) of travel of the fluorescent X-ray from the target area (1a) towards the spectroscope (8) and a surface of the sample (1) is equal to the angle &thgr;2 formed between a second path (82) of travel of the fluorescent X-ray from the target area (1a) towards the second detector (12) of the energy dispersive type and a surface of the sample (1), but the second path (82) is shorter than the first path (81).

摘要： In an optical time domain reflectometer, an optical pulse output unit supplies optical pulses intermittently to an optical fiber to be measured in accordance with the input timing of a cyclic signal. In response to the intermittent supply of the optical pulses, a reflected light data sampling unit samples the signal obtained from the optical fiber while the optical pulses are being supplied, while a noise data sampling unit samples the signal obtained from the optical fiber when the optical pulses are not supplied. Each of two or more groups of reflected light data and noise data obtained by the above sampling operations is averaged. After the averaging operations, an waveform data operating unit subtracts the noise data from the reflected light data in the common mode components corresponding to each other in terms of time, and then transforms the resultant data logarithmically to thereby operate the waveform data thereof.

摘要： The present invention produces halftone dots which shows small fluctuations in area irrespective of variation of the relative position of the address range of screen pattern data against the pixels. a plurality of exposure-decision points RC, SP1, SP2, and SP3 are set for each pixel RP. Screen pattern data is compared with an image signal at each of the exposure-decision points, and the results of comparison are output as preliminary decision value. The preliminary decision value is summed up to make total value Tex for each pixel, and the total value Tex is further accumulated in a primary scanning direction U to make total-sum value .SIGMA.Tex. When the total-sum value .SIGMA.Tex for a pixel is equal to or greater than the number of exposure-decision points, the pixel is determined to be exposed, and carry-over data Dco, which is obtained by subtracting the number of the exposure-decision points from the total-sum value .SIGMA.Tex, is transferred to the next pixel. When the total-sum value .SIGMA.Tex for a pixel is less than the number of the exposure-decision points, the pixel is determined not to be exposed, and the total-sum value .SIGMA.Tex is transferred to the next pixel as the carry-over data Dco.

摘要： An image reading method and apparatus therefor where charge-coupled devices (CCDs) and similar devices are utilized, especially for making adjustments to compensate for read-out position errors. The apparatus for reading images includes a circuit for generating an adjusted read-out address in order to obtain the desired image signals. The adjusted read-out address is obtained by using the actual data derived from scanning a sample chart with an image device, and computed reference data which is the same data that would be obtained if the sample chart is scanned with an ideal optical system. The sample chart comprises a series of lines provided at regular intervals. An apparatus and method for reading images inexpensively and easily is thus obtained, and which allows the reproduction of original images without distortion, color error or the like.

摘要： Experiential gradation correction curves for sample images are prepared. By analyzing the experiential gradation correction curves and accumulated density histograms of the sample images, two points (Y.sub.1, Q.sub.1) and (Y.sub.2, Q.sub.2) are specified, where Y.sub.1 and Y.sub.2 are values of accumulated occurrence and Q.sub.1 and Q.sub.2 are halftone dot percentages for image reproduction. The values Y.sub.1 and Y.sub.2 through an accumulated density histogram of an original image whose gradation is to be corrected. A gradation correction curve Q=G(x) is determined so as to pass through the two points (x.sub.1, Q.sub.1) and (x.sub.2, Q.sub.2).

摘要： A printed image (I.sub.t4) is produced with halftone images for respective color printers while so-called rosette moire and a color shift from an original iamge are prevented. Halftone dots (H.sub.m4, H.sub.c4, H.sub.k4) are formed in linear shapes extending in respective prescribed directions, thereby forming parallel lines with respective intervals (d.sub.m4, d.sub.c4, d.sub.k4). These extensional directions and intervals of parallel lines are so established that they effectively prevent the rosette moire and the color shift.

摘要： A photosensitive film is scanned with nine laser beams for recording an image on the same. The subscanning pitch .DELTA.X.sub.1 is so determined as to be 4.5 P, where P is an alignment pitch of photospots formed by the laser beams. Scanning lines which belong to a "front line group" and are scanned in a main scanning are spatialy alternated with other scanning lines which belong to a "rear line group" and are scanned in the next main scanning.

摘要： A clock generator (15) and a delay circuit (16) create N dot recording clock signals (.phi..sub.1 to .phi..sub.N) of a cycle t, delayed by t/N. A counter (20) counts a detecting time interval between a start sensor (12) and an end sensor (14) for every surface of a polygon mirror (8) to generate time resolution t/N. The difference between the count value and a reference count value set in a latch (24) is input to a subtracter (23), so that a translation table (28) outputs clock crossover timing responsive to the difference. A latch (17) and an encoder (18) select an N dot recording clock signal synchronous with detection output of the start sensor (12) for every surface of the polygon mirror (8). A second selector (33) outputs a crossover dot recording clock signal (.phi..sub.X) for image recording by performing crossover from the selected dot recording clock signal to other dot recording clock signals that are sequentially along the clock crossover timing.
