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.

An X-ray inspection apparatus includes an X-ray irradiation unit that irradiates an article with X-rays, an X-ray detection unit that detects the X-rays transmitted through the article, an inspection unit that generates an X-ray transmission image of the article based on a signal output from the X-ray detection unit and performs inspection of the article based on the X-ray transmission image, and a control unit that controls the X-ray irradiation unit and the X-ray detection unit. The control unit executes a first control of controlling the X-ray irradiation unit such that an irradiation output is increased if a detection output of the X-ray detection unit is decreased when the control unit controls the X-ray irradiation unit such that the irradiation output of the X-ray irradiation unit becomes a first irradiation output. The control unit executes the first control in a state where the article is not irradiated with the X-rays.

A weighing device includes a supply unit, a weighing unit, a stock unit, a discharge unit, a transfer unit, and a revolving mechanism. The supply unit supplies a target object to a container revolving in the weighing unit. The weighing unit weighs the container while revolving the same. The stock unit stocks a plurality of containers while holding the plurality of containers three-dimensionally and revolving them. The discharge unit discharges the target object from the container while revolving the container.

A noise canceling apparatus () comprises an amplifier () for amplifying a measured signal (ms) outputted from a measuring device (), an analog filter (), an ADC (), a digital filter (), a coefficient control section (), and a data input section (). The digital filter () is a notch filter for attenuating a frequency component of a quantitative signal D(n) outputted from the ADC () at a plurality of notches (stop bands). A transfer function of the digital filter () is expressed by the product of a plurality of factors each having a root that corresponds to each one of the plurality of notches. The coefficient control section () changes a frequency component of a root corresponding to a notch selected from the plurality of notches, and thereafter, expands in a polynomial the transfer function of the reconstructed digital filter (). On the basis of the polynomial thereby obtained, a new series of filter coefficients is calculated. A filter characteristic is controlled in such a manner that it conforms to a frequency variation of a fixed-period vibration noise, whereby the fixed-period vibration noise that varies in frequency is attenuated with a high degree of precision.
