摘要： A plurality of magnetic flux measurement data corresponding to two dimensional grids are obtained, then the magnetic flux measurement data are convoluted to sampling unit functions in x-direction and y-direction to obtain an interpolation function. Magnetic field is illustrated by isomagnetic contour lines based on magnetic flux measurement data and interpolation values which are obtained based on the interpolation function. One of the sampling unit functions is replaced with a differential function thereof to obtain partial differential values of arbitrary points.

摘要： A memory access method convolutes plural data using maximal-sequence codes having individual phase shifting quantities and writes the convoluted data into a cyclic memory (1, 12, 13, 14, 21). The memory access apparatus reads out a desired data from the cyclic memory (1, 12, 13, 14, 21) using corresponding maximal-sequence code. A memory access method convolutes plural data using sequence codes which is obtained weighting factoes and maximal-sequence codes having individual phase shifting quantities and writes the convoluted data into a cyclic memory (1, 12, 13, 14, 21).

摘要： Cross-correlation values representative of cross-correlation of an electrocardiogram pulse with a rectangular pulse window which consists of a negative rectangular pulse, a positive rectangular pulse and a negative rectangular pulse are obtained. An R-wave of the electrocardiogram is detected by a peak of the cross-correlation values is detected. Then a magnetocardiogram in synchronism with the R-wave of the electrocardiogram is detected. Magnetocardiograms corresponding to individual cycles of a magnetocardiogram can be added as required.

摘要： Plural vector magnetic flux meters (12) are disposed based on predetermined relationships in their positions, to obtain vector magnetic flux at plural points. The obtained vector magnetic flux includes magnetic flux components in plural directions. Curved surface interpolation is carried out based on the magnetic flux components in the corresponding direction to obtain magnetic flux components for arbitrary points. Magnetic flux components in plural directions for an arbitrary point are obtained by selecting the obtained magnetic flux components for the arbitrary point belonging to a region which overlaps with all interpolation regions for corresponding magnetic flux components of the magnetic flux. Vector magnetic flux corresponding to a condition that differences between positions of pickup coils (62a, 62b, 62c) of corresponding vector magnetic flux meters (12) and the predetermined position (61e) of the vector magnetic flux meter (12) are supposed to be 0, are obtained based on the obtained magnetic flux components in plural directions and the relative positions of the pickup coils (62a, 62b, 62c).

摘要： A constant bias current is supplied to a superconducting quantum interference device (2). A predetermined voltage is subtracted from output voltage from the superconducting quantum interference device (2). The predetermined voltage is determined to be a voltage which corresponds to a point in a monotonously varying portion of a magnetic flux-voltage conversion coefficient function of a superconducting quantum interference device (2). The subtraction result is supplied to an integrator (4f). The integration result is converted to a current signal and then is supplied to a feedback coil (2c) of the superconducting quantum interference device (2).
