摘要： PROBLEM TO BE SOLVED: To provide a calculation method for magnetic model, preventing the divergence of the solution of a normal equation acquired by a least-squares method, that is, of magnetic sources, thereby acquiring a more accurate near-field magnetic field calculation values and isomagnetic field curves.
SOLUTION: A plurality of groups of measured data on an external magnetic field are acquired (ST1), then fictive data are set at a position where no measured data exist, and the fictive data are approximated by using the measured data and a function assuming that a distant magnetic field is zero (ST2). Here, the number of groups of the fictive data is set to be smaller than the number of groups of measured data. Then, a stipulated value on the maximum magnetic quantity and the number of times of repetitive calculations are set (ST3 and ST4). Thereafter, calculations are performed on the normal equation acquired by the least-squares method and on the magnetic sources (ST5). The calculations on the normal equation and magnetic sources are repeated, while increasing the stipulated value on the magnetic sources, until all the magnetic sources are equal to or smaller than the stipulated value, or the number of repetitions come to the set value (ST6 to ST8).

摘要： PROBLEM TO BE SOLVED: To accurately measure with a light sensor configured on the basis of a PRR method(a method of Polarization Rotated Reflection). SOLUTION: In this optical sensor configured on the basis of a PRR method, a polarized wave plane maintenance fiber 5 transmits a measurement light SL, while a disturbance application mechanism 40 can periodically apply disturbance T capable of changing a phase difference of the measurement light SL to the polarized wave plane maintenance fiber 5. Measurement information S acquired during the forcible application of the periodic disturbance T to the polarized wave plane maintenance fiber 5 by the disturbance application mechanism 40 is averaged, a magnetic field intensity near a Faraday element 2 or a current is obtained on the basis of an average value Sa of the measurement information S. By averaging the measurement information S acquired during the application of the periodic disturbance T, a phase change caused by external factors can be sufficiently reduced (or cancelled) to obtain the accurate magnetic field intensity and current.

摘要： PURPOSE:To simplify work by connecting a compensating coil to a pickup coil and fusing a superconducting wire of the compensating coil with the use of a heat source provided with a switch installed externally. CONSTITUTION:For instance, if the sensitivity of a magnetometer is needed to lower down to one-tenth, a switch of a heat source corresponding to a first compensating coil (20muH) 3a is turned on. When the switch is turned on, the heat source heats to fuse a superconducting wire corresponding to a second compensating coil. Thereby flowing current corresponding to input magnetic flux phiin is allowed to flow in an input coil 2 through the second coil 3a as a current path. In this case, since the input current sensitivity as a squid element is constant, the magnetic flux detecting sensitivity decreases with the decrease of input current. In other words, the sensitivity decreases down to the degree of one-tenth compared with the normal detecting sensitivity. If the detecting sensitivity is needed to lower down to one hundredth, a switch of a heat source corresponding to the compensating coil 3b is turned on. As a result, the magnetic flux sensitivity can be changed by very simple work.

摘要： PURPOSE:To enable the connecting of a pattern of a thin film coil to a superconductive lead easily and firmly, by a method wherein the superconductive lead is inserted through a through hole with a superconductive thin film formed on a substrate and a superconductive material is pressure-welded at the lead inserted part. CONSTITUTION:Through holes 5, 6, 7 and 8 are formed on a quartz substrate 2, and then a thin film coil pattern 3 and a lead pattern 4 are deposited using a superconductive material in such a manner that the through holes 5 and 6 and those 7 and 8 serve as starting points and ending points respectively. Here, superconductive thin films are formed on the respective through holes 5, 6, 7 and 8 as well. When an external lead 10 is connected to the thin film coil 1, the lead 10 is inserted through the through hole 7 and then superconductive material 11 such as lead is pressed from above the lead inserted part to fasten the lead 10 as being fitted thereinto. Thus, the lead is connected securely to through holes.

摘要： PURPOSE:To mathematically efficiently demagnetize a hull and, at the same time, to minimize the magnetic field in a specific direction by finding the magnetic moment of the hull by calculating dipole moments from the three component data of magnetic fields. CONSTITUTION:A plurality of magnetic sensors D1-DN are arranged below a hull 1. The magnetic field and coil effect of the hull in an un-demagnetized state are calculated as a plurality of dipole moments from the three components Hx, Hy, and Hz of the magnetic fields detected by the magnetic sensors. The magnetic moments are reduced by calculating the dipole moments as a magnetic source. In this demagnetizing method, the magnitude of the magnetic source becomes clear, since the plurality of dipole moments at a specific position in the hull are specified from the magnetism detected data on three axes of Hx, Hy, and Hz. The coil effect can also be specified from the moment of the specified position.

摘要： PURPOSE:To realize a skid element which can obtain a large output, by arranging two superconducting rings, a pair of Josephson junctions, superconducting coils so connected as to generate magnetic fields opposite to each other within the superconducting rings. CONSTITUTION:A skid element is made up of two superconducting rings 7 and 8 symmetrical to each other formed on a substrate 1, a pair of Josephson junctions 11 and 12 arranged at the center position on the superconducting rings 7 and 8 and superconducting coils 9 and 10 made of multilayer thin films respectively within the superconducting rings 7 and 8 and so connected as to generate magnetic field opposite to each other and flows a DC drive current through the junctions 11 and 12. And as the two superconducting rings 7 and 8 are placed in parallel viewed from the junctions 11 and 12, the inductance Ls of the skid element is lessened equivalently. Besides, as opposite magnetic fields are generated in the superconducting coils 7 and 8, a shielding current equivalent to the two superconducting rings flows through the junctions 11 and 12 thereby achieving a higher magnetic flux conversion efficient from a pickup coil.
