摘要:
A blood dialyzer is produced by a process in which a plurality of artificial composite fibers having core portions consisting of a water-insoluble core liquid and surrounded by sheath portions consisting of a fiber-forming polymer are subjected to a removal of almost all of the core liquid; the resultant hollow fibers are bundled; the hollow fiber bundle is packed in a cylindrical case having open end; end portions of spaces left between the hollow fibers peripheries and between the hollow fibers and the inside surface of the cylindrical case are sealed with a bonding material, to fix the hollow fiber bundle to the cylindrical case at the end portions thereof; and the hollow fibers in the cylindrical case are cleaned with a cleaning liquid comprising at least one aliphatic monohydric alcohol having 3 to 8 carbon atoms.

A blood dialyzer having semipermeable polymeric dialyzing membranes is sterilized by impregnating the dialyzing membranes, for example, dialyzing hollow fibers, with an aqueous solution of a .gamma.-ray-absorbent and water-soluble dihydric aliphatic alcohol and irradiating .gamma.-rays to the dialyzing membranes, to prevent the deterioration of the dialyzing membranes and the generation of ultraviolet-ray-absorbent substance in the dialyzing membrane.

摘要:
An image-processing apparatus, as well as an image-processing method, is provided with a first inspection circuit which, with respect to density values of pixels within a specific area consisting of a target pixel and pixels in a vicinity thereof in image data for each color component, calculates an average density value, the sum of density differences, that is, the sum of absolute values of differences between the target pixel and the peripheral pixels, and the number the peripheral pixels having the same density value as the target pixel, so that a judgement is made as to whether the target pixel is a maximum value or a minimum value, and also calculates a run-length and the degree of busy from the pixel forming the maximum value or the minimum value. Moreover, based on the run-length and the degree of busy, the second inspection circuit extracts a pixel weight switching signal for each of the color components, and detects the periodicity of meshes of image data by counting pixels not less than the standard value or not more than the standard value based on the pixel weight switching signal within a predetermined counting area. With this arrangement, it becomes possible to carry out the discrimination between character areas and mesh areas as well as the discrimination between black character areas and white character ares with high precision.
