    摘要： A nuclear magnetic resonance apparatus including: a cup-shaped high-temperature superconductor 20 having a hollow cylindrical shape or portion cooled to not more than a superconducting transition temperature in a vacuum insulating container 22; and a detection coil 12 for detecting an NMR signal of a material 11 to be measured inserted into the hollow cylindrical portion 20a of the high-temperature superconductor. The high-temperature superconductor is magnetized in an axial direction, a static magnetic field is thereby generated in the hollow cylindrical portion in a cylinder axial direction, and the NMR signal of a material is detected by the detection coil and the existing spectrometer. A strong static magnetic field comparable to a conventional superconducting magnet is formed without using a refrigerant (liquid helium) essential for operating the conventional superconducting magnet, and a strength distribution of the static magnetic field is homogeneous.

    摘要： A controlling method for a nuclear magnetic resonance apparatus. The method includes: (A) cooling the high-temperature superconductor at a magnetization low temperature sufficiently lower than a superconductor transition temperature, and magnetizing the high-temperature superconductor with a magnetic field; (B) raising the temperature of the high-temperature superconductor at a magnetic flux setting temperature higher than the magnetization low temperature and lower than the superconductor transition temperature and setting a predetermined magnetic flux density; and (C) controlling the high-temperature superconductor in an operation temperature range lower than the magnetic flux setting temperature. Therefore, a strong static magnetic field comparable to a conventional superconducting magnet is formed without using a refrigerant (liquid helium) essential for operating the conventional superconducting magnet, and a magnetic flux density of the static magnetic field is held constant.

    摘要： In order to improve the stabilization and the heat-resistance of a strain gauge, the strain gauge is made of an amorphous alloy including Ni (nickel), Cr (Chromium) and Si (silicon). The amorphous alloy including Ni, Cr and Si has a high crystallization point, its temperature co-efficient of resistance is almost zero obtained by annealing. The amorphous alloy is stabilized from low to high temperatures and thus can be used from low to high temperatures without compensation. The amorphous alloy is a non-magnetic substance and the strain gauge thus is not substantially affected by external electromagnetic noise.

    摘要： A level gauge for liquid helium comprising a sensing element in the form of a ribbon wire made of superconductive alloys and a tube supporting the sensing element, which tube is inserted into liquid helium upon measurement. The superconductive alloys are represented by a formula Zr.sub.100-x.(Ru.sub.y.Rh.sub.1-y).sub.x in which x represents contents of Ru and/or Rh in atomic % and in a numerical value of 22.5.ltoreq.x.ltoreq.27.5 and y represents a numerical value of 0.ltoreq.y.ltoreq.1. The alloys are made of an amorphous phase obtained by rapid quenching a molten alloy material and have a superconducting transition temperature, Tc, of 4.2.degree. to 4.5.degree. K. When the level gauge is immersed in liquid helium, a portion of the sensing element below the level of the liquid helium has a zero electric resistance because of the superconductivity of the alloy, so that the level of the liquid helium can be detected by a variation in resistance of the sensing element.

    摘要： A level gauge for liquid helium suitable for use under a higher vapor pressure comprising a sensing element in the form of a ribbon wire made of superconductive alloys and a tube supporting the sensing element which tube is inserted into liquid helium upon measurement. Chemical composition of the superconductive alloys are represented by a formula, Zr.sub.100-x (Ru.sub.1-y Rh.sub.y).sub.x, in which x represents a content of Ru and/or Rh in atomic % and in a numerical value of 17.0.ltoreq.x.ltoreq.22.5 and y represents a numerical value of .ltoreq.y.ltoreq.1. The alloys are made of an amorphous phase obtained by rapid quenching of a molten alloy material and have a superconducting transition temperature, Tc, of 4.5.degree. to 5.2.degree. K. When the level gauge is immersed in liquid helium, a portion of the sensing element below the level of the liquid helium has a zero electric resistance because of the superconductivity of the alloy, so that the level of the liquid helium can be detected by a variation in resistance of the sensing element.
