  • Publication number: 20180198363
    Abstract: [Object] [Solving Means] A discharge device includes a discharge unit and a cut-off detection unit. The discharge unit is configured to discharge a capacitor at a variable discharge current value on the basis of a voltage of a rectified signal obtained by full-wave rectifying an AC voltage input via an input filter including the capacitor. The cut-off detection unit is configured to monitor the voltage of the rectified signal and to detect whether or not a power supply is cut off on the basis of a change of the voltage when the capacitor is discharged by the discharge unit at a specific discharge current value.

  • Patent number: 9864022
    Abstract: The present invention is to provide a structure that can effectively reduce quench in an open superconducting magnet. In order to do so, a pair of superconducting magnets is respectively provided with a primary coil, a shield coil to suppress a leakage magnetic field of the primary coil, and a coil bobbin. The coil bobbin has a cylindrical part on which the primary coil is wound, a ring-shaped end plate on which the inner periphery part is fixed to an end of the imaging space side of the cylindrical part, and a support member preventing the outer periphery part of the ring-shaped end plate from being displaced on the imaging space side. Hence, deformation of the end plate is suppressed to prevent deformation of the primary coil. This can reduce quench caused by the deformation of the primary coil.

  • Publication number: 20170321582
    Abstract: An amount of electric power consumption by a battery is reduced, and deterioration of a coil is suppressed by efficiently heating an injector and melting urea crystals at an early stage. A control device for a reducing agent injection device fills the device with a reducing agent at a start-up of an internal combustion engine and executes control for injecting the reducing agent into an exhaust passage of the internal combustion engine by the injector. The control device includes an energization control section that executes energization control in which, after an exhaust temperature of the internal combustion engine becomes equal to or higher than a specified threshold value, a temperature of the injector is increased by energizing the coil of the injector for a specified time and melting of the crystals of the reducing agent precipitated in the injector is promoted.
