  • Patent number: 9708001
    Abstract: An automatic steering system for a working vehicle, for automatic maneuvering of the working vehicle running on a working ground surface along a desired running path, in which the influences of various ground surface environments and of any aging degradation and/or individual variation of the working vehicle may be minimized, and the automatic steering operation may be conducted with improved stability. The automatic steering system includes a measurement section for acquiring measurements including those of the position, velocity, heading direction, and attitude of the vehicle and a data processing section. The data processing section includes a vehicle related parameter estimator for determining a value of a vehicle related parameter and a ground surface related parameter estimator for determining a value of a ground surface related parameter.

  • Patent number: 9701637
    Abstract: An object of the present invention is to provide a probe for imaging a ?-sheet structure protein which can be used for the diagnosis of conformational diseases, particularly disease (tauopathy) having a cardinal symptom such as intracerebral accumulation of tau protein, for example, Alzheimer's disease. Another object of the present invention is to provide a compound which is highly specific to tau and can image tau with satisfactory sensitivity, and also has high brain transition, low or non-recognized bone-seeking properties and low or non-recognized toxicity. According to the present invention, the above problems are solved by providing a compound of a formula I (wherein A, R1, R2, R3, R4, R5, R6, Ra and Rb are as defined in the present description) or a pharmaceutically acceptable salt or solvate thereof.

  • Patent number: 9121929
    Abstract: A position output device for outputting position data indicating a current position of an object, is based on position data of a determined current position of the object as determined by a satellite navigation system. When a position jump has occurred in the position data from the satellite navigation system, an appropriate current position is outputted. An estimated current position is generated based on the output position outputted at the latest update time. It is determined whether or not a position jump has occurred, based on the distance between the estimated position and the satellite navigation system-based determined position, which is being updated by the satellite navigation system. When it is determined that a position jump has occurred, a position adjustment vector is generated by calculation, which is then used to generate an adjusted position.

  • Patent number: 8628949
    Abstract: An apparatus for producing a probe carrier in which ambient humidity for a plurality of nozzles of a liquid ejection device for ejecting droplets of solutions containing probes to the surface of a carrier is controlled to 50% or more, preferably 60% or more. A part of solution supply passages to the plurality of nozzles is constructed from gas permeable membranes permitting gas-liquid separation under reduced pressure. These gas permeable membrane portions are gathered and altogether placed under reduced pressure to remove air bubbles from the respective solutions supplied to the plural nozzles and decrease the amount of a dissolved gas, which causes air bubbles to be generated.

  • Patent number: 7684943
    Abstract: A method for appropriately managing the quality and distribution of a probe carrier. Probe carriers manufactured by a probe carrier manufacturing apparatus having ejecting portions for ejecting probe solutions, each containing a probe, which can be specifically coupled with a target substance, for applying the probe solution on a carrier, and a plurality of probe tanks storing mutually different probe solutions for supplying ejecting portions. Each probe tank is labeled with the bar-code. The labeled bar-code is read by the bar-code reader. On the basis of the read bar-code, the probe solution stored in the probe tank is identified. On the other hand, the probe tank is mounted on the ejecting portion.
