  • Publication number: 20250162798
    Abstract: A method for recognizing a location of an overhead hoist transport for an overhead hoist transport system, by which a process designing time can be shortened and thus costs can be reduced by installing location indicators in the same way at each semiconductor factory at the time of process design by acquiring accurate location information of the overhead hoist transport in real time and determining a work location based on the location information, there is no need to reattach location indicators and thus there is no need to work at heights due to reattachment work of the location indicators even in a case of changing work environment such as changing layout of a process or changing position of equipment so that a work time and costs thereof can be significantly reduced, and it is possible to remarkably improve post management and significantly improve efficiency of logistics transportation.

  • Patent number: 10162028
    Abstract: Provided is a low magnetic field and ultra-low magnetic field NMR and MRI apparatus. The low magnetic field and ultra-low magnetic field NMR and MRI apparatus includes a SQUID sensor and a prepolarization magnetic field coil. The prepolarization magnetic field coil generates a prepolarization magnetic field to polarize a sample. The prepolarization magnetic coil generates a counter pulse in a direction opposite to that of the prepolarization magnetic field immediately before or immediately after the prepolarization magnetic field is generated. The counter pulse demagnetizes wanted magnetization including that of the prepolarization magnetic field coil itself.
