Filed: 1982-07-12
Abstract: PURPOSE:To enable the average atomic number of irradiated points to be measured with relatively few detection signals by summing the outputs of two reflected-electron detectors which are arranged in different directions symmetrical to the normal of the sample surface, and storing the result of the operation in a memory.

Title: Calculation method for approximate solution of optimization problem
Inventor: TAKEUCHI MASARU
IPC: G06F19/00
Filed: 1991-05-27
Abstract: PURPOSE:To attain the automatic correction of a coding operation where a calculation method functions effectively by replacing a multiple assembly with a defining area of a function to be optimized. CONSTITUTION:The multiple assemblies P following a step 5 where a character string having the value approximate to the optimum value contain many character strings having the larger function values than those of the multiple assemblies precedent the step 5 in terms of an order structure. Thus the schemata are sequentially formed in the step 5 for the assemblies P in order to secure the optimum function value. That is, a correlative coefficient, a relative coefficient, etc., are used as the scales of relationship of a step 6 and function to quantize the relationship among the character positions of the assemblies P. In a step 7 the character positions are changed in the character strings so that the possibility of cutting is reduced. Thus the schemata can be shortened for more advantageous optimization. Under such conditions, a coding operation is automatically corrected when the substitutes are sequentially carried out in both steps 6 and 7 so that the sum of scales is maximized for the relationship of the following positions adjacent to each other.
