Filed: 1984-12-25
Abstract: PURPOSE:To uniformize void, by a method wherein a hydrogen storage container is filled with an alloy for hydrogen storage, formed in a shape conforming to the internal shape of a container, without crushing thereof. CONSTITUTION:A cylindrical container body 10 is formed by an alloy 11 for hydrogen storage, a hydrogen gas outlet and inlet 12, a sintered metal 13, and quartz wool 14. The sintered metal 13 and the quartz wool 14 form a filter which prevents powder, pulverized through hydrogenation of the alloy, from leak past the container 10 through the hydrogen outlet and inlet 12 to the outside. The internal shape of the container 10 is a column, and thus, the alloy 11 is cast in a column by means of a casting mold.

IPC: G06K7/10
Filed: 1988-11-04
Abstract: PURPOSE:To read a mark with high accuracy by correcting the inclination of a scanning line by the detected result of a reference mark detecting means. CONSTITUTION:After a first reference mark, which is either a mark 10 or 11, is detected, an interval in which another reference mark, either the mark 10 or 11, appears can be expected. Therefore, in a limitation interval retrieving mode, the retrieving action of the reference marks 10 and 11 is executed only in the limited interval of each scanning line. Consequently, the retrieval of the reference mark can be processed at a high speed. Further, it is detected whether the mark is entered in a mark entering column 8 or not while the inclining angle and the inclining direction of a mark sheet 12 are supervised based on four states expressed by the existence of the detection of a pair of right and left reference marks 10 and 11. Thus, the inclining angle can be corrected properly, and the mark can be read with extremely high accuracy even when the inclining angle of the mark sheet 12 is changed in the interval from the start of a scanning and the completion of the scanning.
