Title: Vertex detecting method
Inventor: EJIRI KOICHI
IPC: G06K9/46
Filed: 1984-12-26
Abstract: PURPOSE:To detect a correct vertex by obtaining an angle difference between mean vectors before and after a noticing point on a curved line and detecting this noticing point as the vertex of the curved line when the angle difference exceeds a predetermined value. CONSTITUTION:A vector adder 110 change a direction code held by stages 105, 106, 107 into a vector expression and adds to obtain a mean vector Sc. A differential device 113 calculates an angle difference between the mean vector Sc and a vector Cn of a noticing point. In a comparator 115, the angle difference thetais compared with a predetermined value Th1 and if theta>Th1, a switch 116 is operated, and an output (Sc) of a vector adder 110 and the output of the other vector adder 111 are outputted to a difference device 113. In the difference device 113, the angle difference ¦ScEc¦ is obtained and compared with a predetermined value Th7 by the compara tor 115. When the angle difference is larger than Th7, the noticing point is detected as a vertex.

Inventor: MATSUURA YOSHIKI
IPC: G21K7/00
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To confirm the positional relation between a sample housed in a sample container and the route of X rays even when the sample is not visually confirmable by confirming the position of the sample using secondary X rays generated by foil interposed between a collimator and the sample. SOLUTION: X rays 11 radiated from an X-ray source 10 are made incident to foil 14 after being converged into a narrow beam through a pin-hole collimator 12. Secondary X rays (fluorescent X rays) 20 generated from the area of the foil 14 irradiated with the X rays reach a two-dimensional X-ray detector 22 after passing through a sample 18 in a sample container 16 and its peripheral space. Therefore, the outline of the sample 18 can be recognized as an enlarged picture 24. When this X-ray microscope is utilized as a sample position confirming means for X-ray diffractometer, beryllium which makes the sample contained in the container invisible can be used as the material of the sample container.
