    摘要： A superconducting magnet includes: first and second torus coolant containers substantially symmetrically, vertically arranged to have a space and a symmetrical plane therebetween for storing a coolant. Each of the first and second torus coolant containers includes therein a main coil bobbin with a main coil for generating a measurement magnetic field, a shield coil bobbin with a shield coil for generating a shielding magnetic field for suppressing outside leak of the measurement magnetic field, a plate member vertically reinforced at a plane thereof opposite to a plane thereof facing the symmetrical plane for supporting the shield coil bobbin and the main coil bobbin. The main coil bobbin is further supported by the shield coil bobbin, to cause the main coil to generate the measurement magnetic field having a substantially uniform magnetic field intensity at a middle region of the space. A magnetic resonance imaging apparatus using the superconducting magnet is also disclosed.

    摘要： An engine control system includes a unit which outputs a command for changing an air-fuel ratio of an exhaust gas, a unit which computes an in-cylinder oxygen concentration, a memory which stores a first value and a second value of parameters (ignition timing, injection pressure, pilot injection quantity). The first value is set in a case that the in-cylinder oxygen concentration is a first oxygen concentration. The second value is set in a case that the in-cylinder oxygen concentration is a second oxygen concentration which is higher than the first oxygen concentration. The values of the parameters are set in such a manner as to correlate to the in-cylinder oxygen concentration of during a transition period of the air-fuel ratio. The values of the parameters are obtained by an interpolation based on the first and the second value of the parameter and the in-cylinder oxygen concentration.

    摘要： An exhaust gas cleaning apparatus includes a combustion mode shifter that shifts combustion in a cylinder of an engine from a lean-burn mode to a rich-burn mode for enabling a LNT to reduce NOx contained in the exhaust gas. The combustion mode shifter is configured to: estimate a torque-producing fuel quantity for a fuel injection made by a fuel injector when the combustion is in the lean-burn mode; estimate an excess oxygen ratio for an upcoming fuel injection during the shifting of the combustion from the lean-burn mode to the rich-burn mode; estimate a fuel burning percentage for the upcoming fuel injection based on the excess oxygen ratio; set a command injection quantity for the upcoming fuel injection based on the torque-producing fuel quantity and the fuel burning percentage; and control the fuel injector to inject the command injection quantity of fuel into the cylinder in the upcoming fuel injection.
