  • Publication number: 20170373785
    Abstract: A receiving device includes a light source, a wave multiplexer, a converter, a demodulator and a processor. The light source outputs local light. The wave multiplexer causes the local light to interfere with a received signal to acquire an optical signal. The converter converts the optical signal into an electrical signal. The demodulator demodulates the electrical signal to acquire a demodulated signal. The processor is configured to correct an error of the demodulated signal. The processor is configured to acquire a signal correction amount and/or an error rate. The processor is configured to control the light source in order to adjust an output intensity of the local light based on the signal correction amount and/or the error rate.

  • Publication number: 20170176362
    Abstract: A probe head in a nuclear magnetic resonance measurement apparatus includes a rotating mechanism. In the probe head, an exhaust gas having a high temperature or a low temperature is discharged from a discharge port of the rotating mechanism. An additive gas having room temperature is introduced into the probe head through a plurality of ejection holes. The additive gas is mixed with the exhaust gas, and, as a result, an exhaust gas mixture having a temperature closer to room temperature than is the temperature of the sample is produced. A deflector regulates the direction in which the exhaust gas flows.

  • Publication number: 20170088176
    Abstract: A vehicle steering device includes an electric motor; a steering angle sensor; a steering torque sensor; a wheel speed sensor; a cruise controller; and a wheel-alignment support controller configured to compute an anti-one-side pull current value fed to the electric motor for suppressing a one-side pull behavior of a vehicle. The wheel-alignment support controller calculates, according to an integrated torque value, the amount of displacement of an anti-one-side pull steering angle value that corresponds to a midpoint steering angle of a steering system for suppressing the one-side pull behavior of the vehicle. When the vehicle is under cruise control and the vehicle speed is below a first threshold Vth1, the wheel-alignment support controller makes the amount of displacement of the anti-one-side pull steering angle value smaller than that obtained when the vehicle speed is equal to or above the first threshold Vth1.

  • Patent number: 9589721
    Abstract: An automatic tuning assist circuit is coupled with a transmission antenna. The transmission antenna injects a first correction current into, or otherwise draws the first correction current from, the transmission antenna. In the first state, the first auxiliary coil is coupled with the transmission antenna. In this state, the first correction current IA, which corresponds to a current that flows through the first auxiliary coil, is injected into or drawn from the transmission antenna. In the second state, the first auxiliary coil is decoupled from the transmission antenna. In this state, the current that flows through the first auxiliary coil flows through a current path which is independent of the transmission antenna. The state is switched between the first state and the second state with the same frequency as that of the driving voltage.

  • 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.
