  • Threaded connector
    Patent number: 9062804
    Abstract: A threaded connector including female thread and male thread. The female thread is symmetrically disposed on both ends of a coupling. The male thread is disposed at an end of a pipe. The female thread includes buttress thread. A torque shoulder is disposed in front of the buttress thread. The female thread is connected to the torque shoulder via a tool withdrawal groove. A protruding threaded segment is disposed on any one of a fourth to seventh tooth of the female thread to prevent high pressure gas from leaking.

  • Self-shield open magnetic resonance imaging superconducting magnet
    Patent number: 8996083
    Abstract: A self-shield open magnetic resonance imaging superconducting magnet comprises five pairs of coils: shim coils, first main magnetic coils, second main magnetic coils, third main magnetic coils, and shielding coils. The five pairs of coils are symmetric about the center. The shim coils are arranged closest to the center point; the first main magnetic coils, the second main magnetic coils, the third main magnetic coils, and the shielding coils are arranged in sequence outside. The first main magnetic coils are connected with reverse current. The second and third main magnetic coils are connected with positive current for providing the main magnetic field strength. The shim coils are connected with positive current for compensating the magnetic field in the central region. The shielding coils are connected with reverse current for creating a magnetic field opposite to the main magnetic field for compensating the stray magnetic field in the space.
