<p>PURPOSE:To array mask figures for facilitating the production of specimen for observation of any sectional shape by a method wherein, when multiple figures of element parts are arrayed on XY rectangular plane coordinates in a grating type, the origins of each figure are positioned at a specified interval deflected from the origins of adjoining figures. CONSTITUTION:The figures in the first and the second lines are arrayed in the Y axis direction regularly deflected by DELTAy. In such an arrayal, when the figures are sliced in the longitudinal direction along the X axis, the length equivalent to the through hole diameter is visible in the sliced lines between A2 and A2 or between C4d2 and C2 while the length scores of % of the same diameter is visible in the intermediate sliced line between B2 and B2 so that any sectional shape concerned may be evaluated without fail by a specimen produced only one time. When the radius of through hole is assumed as DELTAy, the least sectional length is equivalent to 85% of the through hole diameter to be evaluated satisfactorily. Through these procedures, the specimen need not be produced repeatedly cutting down the time for observation of any sectional shapes remarkably.</p> |
