An apparatus for processing a two-dimensional image obtained by scanning sensor arrays of image detectors perpendicular thereto, the apparatus including an image memory for storing pixel data output by the image detector as a two-dimensional image, a first read-out unit for reading the stored pixel data about a particular detector in a particular array, a second read-out unit for reading pixel data in the neighborhood of the pixel data read by the first read-out unit, a first arithmetic unit for measuring the magnitude of difference in sensitivity between the detector whose pixel data is read by the first read-out unit and the detector whose pixel data is read by the second read-out unit, and a second arithmetic unit for compensating for the deficiency of sensitivity on the basis of the output of the first arithmetic unit.

According to the method of manufacturing an optical matrix device of this invention, semiconductor films and gate insulating films which influence the characteristics of thin-film transistors most are formed in a vacuum (S12, S13), whereby the interfaces between the semiconductor films and gate insulating films are not contaminated. The semiconductor films and gate insulating films are formed in a vacuum, but wires need not be formed in a vacuum (S03). Thus, the semiconductor films and gate insulating films formed in a vacuum are transferred onto the wires formed beforehand (S21). Even if a substrate has a large area, the wires, semiconductor films and gate insulating films of the thin-film transistors can be formed efficiently.

According to the method of manufacturing an optical matrix device of this invention, lyophobic portions which are lyophobic, and lyophilic portions which are lyophilic, with respect to metal ink are formed alternately and parallel, and with a pitch smaller than a width of droplets applied by printing technique, on a foundation of wires to be formed on a substrate. Thus, the ejected droplets extend along edges of the lyophobic portions, while straddling the plurality of lyophobic portions, thereby to improve the accuracy of wire formation. This can form a uniform wire width, and eliminate a possibility of a formed wire making a short circuit with an adjacent wire.

A subtraction image is obtained, by a subtraction process (DSA process), from a live image and a mask image. A lag-behind part included in each X-ray detection signal is considered due to an impulse response formed of exponential functions. The lag-behind part is removed from each X-ray detection signal by a recursive computation to obtain a corrected X-ray detection signal. The live image and mask image are obtained from such corrected detection signals.

A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of a plurality of exponential functions with different attenuation time constants. The lag-behind parts are removed by using impulse responses of the FPD corresponding, for example, to an X-ray dose used in a fluoroscopic image pickup and an X-ray dose used in a radiographic image pickup. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.

A new strain Lactobacillus sp. KPB-176, which does not possess strict selectivity for specific media and which involves no reduction in the productivity of polysaccharides even during subculture, was isolated from kefir grains. When this new strain is cultured on a medium containing milk whey and casamino acid or when on a medium containing carbohydrate and yeast extract, capsular polysaccharides are produced in high yields.

The present invention discloses a join operation processing system in a relational model where a data base processing mechanism provides at least maximum/minimum calculation execution means, reduction sort execution means and the join operation execution means.During the join operation for generating a new table linking tuples of a plurality of pertinent tables based on a common field or plurality of common fields, a minimum extraction range for determining the tuples to be processed is determined with respect to the join field or the plurality of join fields for each table which is considered as the object of the join. The operation rate is thereby improved by omitting the processing referring to unwanted data.

Disclosed is a vertical roller mill wherein a material fed to a casing is ground between a rotary table and a plurality of grinding rollers which are pressed against the rotary table and are rotated as the rotary table is rotated, the ground material being entrained by the upblast of heated gas or the like and discharged out of the casing. A bracket extended above the rotary table for carrying the grinding roller is pivoted at the side of the casing, and a pull-down means is connected with the bracket adjacent to the part thereof at which the grinding roller is supported. The bracket is pulled down by the pull-down means so that the grinding roller may be pressed against the rotary table.

According to a radiographic apparatus of this invention, an image correcting unit corrects offset for every pixel relative to a detection value outputted from a radiation detector having pixels for detecting radiation arranged in a two-dimensional array. In addition, the image correcting unit corrects the offset while holding noise components contained in the detection value. Thus, upon quantitative evaluation of the noises contained in the detection values outputted from the radiation detector, the noises of not only positive values but also negative values can be considered. Consequently, accurate evaluation may be achieved.
