Abstract
Abstract In the microanalysis of a sample face, the signals generated by X-rays reflected by said sample during scanning thereof by an electron beam, are applied to a counter, the output signals of which are applied to a comparator which is set to a desired limit range. Output signals pertaining to subsequent intervals and obtained from said comparator are applied to an additional comparator the output of which, in turn, is connected to a recording device or the like.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
An apparatus for determining and recording the component and distribution of digitally obtained measured values with statistic scattering, falling between predetermined thresholds and characterizing a varying magnitude, comprising, A. a time signal generator for emitting signals characterizing periodically repetitive time intervals, B. a counter having an input receiving signals from said time signal generator and an input for receiving signals of digitally obtained measured values, C. a first memory having an input receiving signals from said counter, D. a first comparator having first, second and third inputs; said first input receiving signals from said intermediate memory, E. limit value adjusters connected to said second and third inputs of said first comparator to apply thereto two predetermined threshold values, F. a second and a third memory having inputs to receive, for successive storing, logic information obtained from an output of said first comparator during a preceding and a successive time interval, G. a second comparator having inputs receiving signals from said second and third memories for effecting an AND-combination thereof, and H. recording means receiving signals from an output of said second comparator.
Claim 2
Independent Claim
182 words
An apparatus for determining and recording the component and distribution of digitally obtained measured values with statistic scattering, falling between predetermined thresholds and characterizing a varying magnitude, comprising, A. a time signal generator for emitting signals characterizing periodically repetitive time intervals, B. a counter having an input receiving signals from said time signal generator and an input for receiving signals of digitally obtained measured values, C. a first memory having an input receiving signals from said counter, D. a first comparator having first, second and third inputs; said first input receiving signals from said intermediate memory, E. limit value adjusters connected to said second and third inputs of said first comparator to apply thereto two predetermined threshold values, F. a second and a third memory having inputs to receive, for successive storing, logic information obtained from an output of said first comparator during a preceding and a successive time interval, G. a second comparator having inputs receiving signals from said second and third memories for effecting an AND-combination thereof, and H. recording means receiving signals from an output of said second comparator.
Claim 3
Dependent Claim
15 words
An apparatus as defined in claim 1, wherein said limit value adjusters are digitally settable.
Claim 4
Dependent Claim
18 words
An apparatus as defined in claim 2, including means for a program-controlled setting of said limit value adjusters.
Claim 5
Dependent Claim
15 words
An apparatus as defined in claim 3, wherein said last-named means is an electronic calculator.
Claim 6
Dependent Claim
18 words
An apparatus as defined in claim 1, wherein at least two apparatuses are arranged parallel to one another.
Claim 7
Dependent Claim
91 words
An apparatus as defined in claim 1, including a plurality of sources delivering different measured values; a separate counter defined in (B), a separate first memory defined in (C), a separate first comparator defined in (D) and separate limit value adjusters defined in (E) associated with each said source; said separate counters, first memories, first comparators and limit value adjusters are controlled by a sole common time signal generator defined in (A) and a common sole coincidence circuit receiving signals from outputs of said separate counters, first memories and first comparators.
