    摘要: A fuel assembly comprises a plurality of fuel rods bundled in grid pattern, a part of the fuel rods containing gadolinium as a burnable poison. At least one of the fuel rod having gadolinium contains gadolinium enriched in at least one kind of isotope of odd mass number more than an isotopic abundance of natural gadolinium. In the enriched gadolinium, a ratio of a content of Gd-155 to that of Gd-157 is 0.1 or less. An average concentration (wt %) G0 of enriched gadolinia is, with M denoting the number of month under rated power operation per one cycle of an equilibrium core, P power density of a nuclear reactor (kw/l unit) and W a sum of isotopic composition, is set in the range shown by the following expression. G0

    摘要: A print control system managing a print job on a job basis and on a page basis. When a print job is interpreted, a job description file and page data for each page are created. The job description file contains the attribute of the entire job and a job element (content) list. An item of page data is associated with the print attribute of each page including image data. The job control module extracts necessary image data according to the job element list and sends it to a printer. Because a plurality of print jobs share the common data, many job management functions, including print job combination and page addition/deletion, can be implemented easily.

    摘要: Electric discharge breakdown in an optical waveguide pattern formed on a crystal substrate having pyroelectric effect is substantially extinguished or reduced, so that the yield of optical waveguide devices in the manufacturing process can be increased. A plurality of optical waveguide patterns 5 are formed, in parallel, by means of heat treatment on a substrate 2 of lithium niobate having pyroelectric effect, and the formed waveguide patterns are cut into a predetermined chip-shape. In the manufacturing method of this optical waveguide device, patterns are formed so that both ends of the optical waveguide pattern 5 are respectively communicated at a position where both ends of the optical waveguide pattern 5 are out of an effective chip range. Further, a dummy pattern 26 is formed at a position close to a waveguide pattern 25.
