The present invention is to provide a method for refining hydrogen with a hydrogen refining device in which the inside of a cell is divided into a primary side space and a secondary side space by palladium alloy capillaries each having one end being closed and a tube sheet supporting the open end of the palladium alloy capillaries, in which impurity-containing hydrogen is introduced from the primary side space to allow hydrogen to permeate the palladium alloy capillaries so as to collect pure hydrogen from the secondary side space. The method for refining hydrogen has a capability of decreasing the removed amount of gas containing impurities and efficiently collecting pure hydrogen from the secondary side space. From hydrogen with 1000 ppm or less of impurities as raw material hydrogen, gas containing impurities that does not penetrate the palladium alloy capillaries is removed from the primary side space at the flow rate of 10% or less of the introduction flow rate of the raw material hydrogen. Furthermore, gas containing impurities that does not penetrate the palladium alloy capillaries is removed from the primary side space at a flow rate based on the content of impurities contained in raw material hydrogen.

Image display apparatus

A stimulable phosphor sheet, on which a radiation image of an object has been stored, is scanned with stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored on the stimulable phosphor sheet during exposure of the stimulable phosphor sheet to radiation. The light, which is emitted by the stimulable phosphor sheet when the stimulable phosphor sheet is scanned with the stimulating rays, is detected, and an image signal representing the radiation image of the object is acquired. The scanning of the stimulable phosphor sheet with the stimulating rays is performed from an object image-carrying edge area, in which a radiation image pattern representing the object has been stored, the object image-carrying edge area being one of edge areas of the stimulable phosphor sheet.

Correction processing is performed on the images, which have the common overlapping area, for correcting pixel values of pixels in at least either one of the images, such that the pixel values of the pixels in the overlapping area of one of the images become identical with the pixel values of the pixels in the overlapping area of the other image. A single image is composed from the images having been obtained from the correction processing.
