  • Patent number: 10614940
    Abstract: A superconducting magnet device with which device breakage caused by a quench can be avoided while helium consumption is reduced. A sheet-like convection-preventing member is disposed at least either above or below a heat transfer member transferring to gaseous helium heat transferred from the outside, so as to cover a helium gas release tube for the gaseous helium, and thus heat exchange performance during transportation is improved. In the case where the quench occurs, the convection-preventing member is lifted upward in the release tube, thereby ensuring to provide a flow path for the gaseous helium and avoiding excessive increase of the internal pressure.

  • Patent number: 9620273
    Abstract: A magnet system generates a highly stable magnetic field at a sample location. The magnet system has a magnet cryostat housing a first superconducting magnet coil and a second magnet coil co-axial to the first magnet coil. The second magnet coil is short-circuited in a superconducting persistent mode during operation of the magnet system. An external power supply during operation supplies current to the first magnet coil via a current lead thereby generating a first magnetic field at the sample location that fluctuates according to the current noise of the power supply, wherein the second magnet coil is positioned and dimensioned in a way that it inductively couples to the first magnet coil such that it generates at the sample location a second magnetic field that compensates the fluctuations of the first magnetic field.

  • Patent number: 9588198
    Abstract: An open type nuclear magnetic resonance magnet system having an iron ring member. A superconducting coil and a superconducting switch form a closed-loop current circuit to generate a magnetic field. The generated magnetic field gains a magnetic flux circuit and executes magnetic field shielding through upper and lower iron yokes and a lateral iron yoke. The magnet system generates a desired magnetic field in a magnet imaging central area via the superconducting coil. To balance the extremely high electromagnetic force between the superconducting coil and the upper and lower iron yokes, an annular iron ring is mounted in a space defined by an inner perimeter wall of in a cryogenic container. The magnetic field distribution between the superconducting coil and the upper and lower iron yokes is changed via the iron ring, so that the electromagnetic interaction force therebetween is reduced.

  • Patent number: 9513095
    Abstract: A system and method for providing information regarding the trajectory of a projectile is disclosed. The system comprises two subsystems: a non-magnetic sleeve designed to fit over the barrel of a gun, with a series of rings of magnetic material disposed thereupon, and an onboard measurement and control system comprising at least one magnetic sensor and control electronics, located within a projectile. As the projectile passes through the sleeve, the magnetic sensors within the projectile produce signals as the projectile passes through the magnetic rings. From the time profile of the signals thus produced, the projectile's linear and angular muzzle velocities are determined.

  • Patent number: 9381374
    Abstract: Described herein are shaped coil TMS electromagnets formed by two bent magnetic coil loops joined at a vertex having an angle between the outer coil regions of the coils that is typically less than 120 degrees (e.g., between about 45 and about 70 degrees, 60 degrees, etc.). The vertex region shaped to optimize the magnetic field projected from the TMS electromagnet. For example, the vertex region may be horizontal or vertical. In some variations the vertex region is formed by re-arranging the conductive windings forming the two coils so that they are no longer arranged in the same columnar structure that they are in the other portions of the bent magnetic coil loops. These TMS electromagnets may be well suited for use in deep-brain Transcranial Magnetic Stimulation.
