  • Patent number: 9547052
    Abstract: There is disclosed an NMR (nuclear magnetic resonance) spinner having a turbine structure and a rotor whose spinning rate can be increased. A vortical channel (44) is formed around the rotor (12). The vortical channel (44) consists of a chamber (66) and a nozzle array (68) mounted inside the chamber (66). The chamber (66) has a cross-sectional area that decreases in an upstream to downstream direction. The cross-sectional area of each nozzle also decreases in an upstream to downstream direction. Gas is introduced into the chamber (66), creating a rotating flow (76, 78, 80) in the chamber (66). Plural inwardly swirling streams are created from the inside of the rotating flow. The inwardly swirling streams are ejected from the exits of the nozzles. This results in jet streams, which are blown against the impeller of the rotor, spinning the rotor at high speed.

  • Patent number: 9533705
    Abstract: A vehicle steering system can keep the comfort of steering feeling for a driver, even in a situation, such as traveling on a cant road or in a crosswind, where a unidirectional-drift behavior of a vehicle occurs, and includes an electric motor, a steering angle sensor, a steering torque sensor, and an EPS_ECU that controls driving power of the electric motor, when the vehicle is traveling straight, based on vehicle information including a steering torque and a steering angle, to perform a control for applying an assist torque to a steering system. The EPS_ECU includes an integrating unit for calculating an integrated torque value obtained by integrating the steering torque, and a steering effort assist controlling unit for performing an anti-unidirectional-drift control over the driving power of the electric motor, when the integrated torque value exceeds the threshold value, so as to cancel the unidirectional-drift behavior of the vehicle.

  • Patent number: 9448463
    Abstract: A digital photographing apparatus includes a focus lens, a focus detection unit that detects focus in a contrast auto focusing (AF) method by moving the focus lens, and a controller that calculates a velocity of a subject from a first focus detection result and a second focus detection result in a continuous shooting operation. The controller restricts a U-turn driving for correcting backlash of the focus lens when the calculated velocity of the subject is equal to or greater than a predetermined value. An AF initiating location and a final correction operation are adaptively adjusted based on the velocity of the subject in each process of the continuous shooting, thereby improving an AF performance and the continuous photographing speed.
