摘要： Ad. X-ray inspection apparatus includes a conveyance unit, an X-ray radiation unit, an X-ray detection, unit, and an image processing unit. The X-ray detection unit has a plurality of direct conversion-type X-ray detection element arrays disposed, side-by-side in rows along a direction intersecting both a conveyance direction in which an object is conveyed by the conveyance unit and a radiation direction in which X-rays are radiated by the X-ray radiation unit The image processing unit has an edge detection unit configured to carry out edge detection processing on an X-ray transmission image to generate an edge detected image, a horizontal direction gradation unit configured to carry out horizontal direction gradation processing on the edge detected image to generate a horizontal direction gradation linage, and a synthesizing unit configured to synthesize the X-ray transmission image and the horizontal direction gradation image to generate a post-processing X-ray transmission image.

摘要： Provided is an X-ray apparatus and a method of controlling an X-ray apparatus capable of detecting a sign of breakage of a filament. A method of controlling an X-ray apparatus for performing control involving controlling a filament current flowing through a filament of a cathode part to maintain constant a tube current flowing between the cathode part and an anode part with a target, includes: monitoring the current value of at least one of the filament current and the tube current; detecting the mode of change in the current value; determining the presence or absence of a sign of breakage of the filament based on the mode of change in the current value; and issuing a warning based on the determination.

摘要： Provided is a highly reliable X-ray inspection device having two line sensors, in which accurate inspection results can be obtained even when there is displacement of the mounting position of the line sensors. The X-ray inspection device is provided with a conveyor unit for conveying an article, an X-ray emitter, a first line sensor, a second line sensor, a detection unit, and a corrected-image generation unit. The X-ray emitter emits X-rays to the article conveyed by the conveyor unit. The first line sensor detects, in a low energy band, X-rays that have passed through the article. The second line sensor detects, in a high energy band, X-rays that have passed through the article. The detection unit detects positional displacement of the second line sensor with respect to the first line sensor in horizontal direction and vertical direction.

摘要： The object of the present invention is to provide a combination weighing device in which supply of articles at an article conveyance part is controlled with good precision. A combination weighing device (100) is provided with article conveyance parts (10, 20) having loading parts (11, 21) of articles and driving parts (12, 22) for driving the loading parts, the article conveyance parts (10, 20) driving the driving parts and thereby causing the articles to be conveyed to hoppers (30) arranged downstream in a conveyance direction, a sensing part (60) for sensing, in non-contact manner, a state of the articles on the loading parts, and a supply control part (82c) for controlling supply of the articles by controlling driving of the article conveyance parts based on a sensing result of the sensing part. The sensing part sense, for a plurality of regions along the conveyance direction, the state of the articles for each of the regions. The supply control part controls the driving based on a physical quantity relating to a height of the articles on the loading parts for each of the regions, the height being ascertained from the state of the articles of each of the regions.
