摘要： An NMR system that enables multiplex resonance measurement includes a superconductivity reception coil, a transmission coil, and four electric current loops. The NMR system also includes an additional coil in which directions of currents that flow in an inner loop and an outer loop are opposite to each other. The additional coil and the transmission coil are arranged such that a direction of a high frequency magnetic field that is developed in the center of the additional coil when electricity is fed to the additional coil is substantially identical with a direction of a high frequency magnetic field that is developed in the center of the transmission coil when electricity is fed to the transmission coil. The electric current loop of the transmission coil is arranged substantially in the middle of the inner loop and the outer loop of the additional coil in which directions of electric currents that flow in the inner loop and the outer loop are opposite to each other.

摘要： Disclosed is to enable to grasp the behavior of protein in the cell by realizing a nuclear magnetic resonance imaging method having spatial resolutions on the scales of cells, and to provide an industrial measure for developing high-quality protein utilizing this technology. In order to realize spatial resolutions in the order of one-tenth the size of the cell, a supersensitive measurement is realized by the combination of the solenoid detector coil and the high magnetic field NMR of not less than 14 Tesla, which has not been used so far. Subsequently, it is combined with the magnetic field uniformity of 0.001 ppm, so that the supersensitive NMR imaging of 0.5 µm, which has been impossible in the related art, is realized. The physico-chemical behavior of protein molecules can easily be clarified, and thus the bioinfomatic network or the process of metabolism of the cell can be brought out.

摘要： Electrical connection of superconducting lines can be achieved by using a low-melting point metal, by mechanical contact of superconducting lines or by welding. According to these methods, however, critical current and critical magnetic field at the connection point are low, and stable connection in a superconducting state has been difficult. The present invention solves these problems and provides a structure and method for connecting superconducting lines (1a, 1b). The present invention provides high-performance, high-stability connection of superconducting lines through magnesium diboride (MgB 2 ) powder (2) arranged between superconducting lines (1a, 1b).

摘要： A superconducting circuit comprising a superconducting joint (13) that joints a niobium titanium superconducting wire (12) has a structure where a filament (18) made of niobium titanium alloy is arranged in a matrix (19) made of copper or copper alloy and other superconducting wire (12). In operation, a magnetic field intensity where the superconducting joint (13) is placed is smaller than the magnetic field intensity where a main coil (1a, 1b) of the niobium titanium superconducting wire (12) in a portion other than the superconducting joint (13) is placed. When the niobium titanium superconducting wire (12) in the superconducting joint (13) and the niobium titanium superconducting wire (12) in the portion other than the superconducting joint (13) are placed in the same magnetic field intensity, a critical current density of the filament (18) in the superconducting joint (13) is lower than the critical current density of the filament (18) in the niobium titanium superconducting wire (12) in the portion other than the superconducting joint (13).
