Title: Method and device to extract prime number and recording medium
Inventor: HORI HIRONOBU
IPC: G06F17/10
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To greatly reduce the processing time required for extracting a prime number and to simply extract a prime number in an arbitrary order by extracting the prime number through an efficient processing based on an advanced theory. SOLUTION: A prime number in next order candidate is computed from a prime number in precedent order and a verification is made to determine whether the candidate is a prime number or not by an already computed prime number (S1 and S2). If the prime number candidate is larger than a certain value, a processing is executed to reduce the verification time (S3). Then, a front and back order prime number product, which includes the prime number candidate and divides, is computed (S4). Then, the prime number candidate is divided by the computed prime number, which constitutes the prime number product in precedent order, to verify whether the candidate is a prime number or not (S5). Then, a computed prime number, which is smaller than the square root of the prime number candidate and is closest to the square root, is computed (S6).  Then, the prime number candidate, which is not verified in S5, is divided by the prime number, which is larger than the maximum computed prime number that constitutes the prime number product in precedent order, is smaller than the square root of the prime number candidate and is in between the prime number that is closest to the square root, to verify whether it is a prime number or not (S7).

Title: Method and device for electron beam length measurement
Inventor: ASARI TOSHIHIRO
IPC: H01J37/28
Filed: 1988-11-25
Abstract: PURPOSE:To give the peak of an addition signal a sharp waveform and to perform high-accuracy length measurement by finding the phase difference of a detection signal based upon a linear scan, and shifting the address of a detection signal according to the phase difference and adding the signal. CONSTITUTION:A scan start signal is outputted from a computer 5 to a deflector control unit 4, which generates a scanning signal which scans an electron beam EB linearly across a pattern P on a sample 2 many times and supplies the scanning signal to an electrostatic deflector 3. Consequently, the electron beam EB is scanned linearly while the scanning position is shifted. A signal obtained by a detector 6 by one scan is amplified 7, digitized by an A/D converter 8, and stored in a buffer memory 9. Further, this signal is transferred to a cumulative adding memory 12 and stored. When a 2nd scan is made, its detection signal is stored in the memory 9 and a phase difference detection unit 11 finds the phase difference between the signal waveform stored in the memory 9 and the signal waveform stored in the cumulative addition memory 12.

Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To detect frequencies which become equal in attenuated quantity at both the upper and lower ends of specific bandwidth by varying and inputting the frequencies of two frequency signals having the specific bandwidth in order, and comparing the levels of their output signals with each other. SOLUTION: When the level P- of a 1st frequency signal BFO- becomes larger than the level P+ of a 2nd frequency signal BFO+ and their comparison result is inverted, shifts of BFO- and BFO+ toward frequency sides higher than the band frequencies at both the upper and lower ends of the specific bandwidth of a 1st filter 16 are detected. Then BFO- and BFO+ can be specified as the frequencies closest to the band frequencies at both the upper and lower ends of the specific bandwidth of the 1st filter 16 in the last state of step width N which undergoes inversion.  Thus, the center frequency of the specific bandwidth which becomes equal in attenuated quantity at both the upper and lower ends of the 1st filter 16 is detected, so when the device operates as an SSB transmitter, a central arithmetic means 38 can find the center frequency from the mathematical mean of the specific 1st and 2nd frequency signals.
