20120106866 | METHOD AND DEVICE FOR CORRECTING IMAGE, AND METHOD AND DEVICE FOR GENERATING CORRECTION TABLE FOR USE IN CORRECTION OF IMAGE - An image correction device geometrically corrects an input image, based on the correction table, which is generated by obtaining a light-direction vector in an objective space corresponding to each pixel position on a corrected image, based on a first projection center located on the rear side of a second projection center as the projection center of the input image in the objective space with respect to the direction of an optical axis corresponding to the input image, obtaining from the light-direction vector an origin-based light-direction vector indicating a direction from the second projection center in which a point corresponding to each pixel position exists in the objective space, exacting a position on the input image corresponding to the origin-based light-direction vector, and recording in the correction table the resampling position in correspondence with each pixel position in the corrected image. | 05-03-2012 |

20120296532 | ENGINE CONTROL DEVICE FOR TRACTOR - In structure of an engine control device for a tractor, when a standard engine performance curve is selected by a mode selection device, and a PTO drive device, which drives an implement attached to a tractor, is turned on, switching to the engine speed maintenance control mode is performed. Further, when a fuel efficient engine performance curve is selected by the mode selection device, and the PTO drive device, which drives the implement, is turned on, switching to the engine speed change control mode is performed. The problem that an engine stall tends to occur when control for maintaining the engine speed is performed while the fuel efficient engine performance curve with lower consumption rate than normal consumption rate is selected can be solved. | 11-22-2012 |

20140076073 | Work Vehicle - Systems and methods are disclosed for improving operability of a work vehicle. In accordance with one implementation, a work vehicle is disclosed. The work vehicle includes a first PTO shaft and a second PTO shaft, the first and second PTO shafts being removably mounted to a vehicle body rear structure and fitted to a power receiving unit on an implement side. The work vehicle also includes a PTO drive mechanism comprising a PTO transmission mechanism, the PTO drive mechanism transmitting rotational power from a power source to the first PTO shaft, and a storage unit storing the second PTO shaft. The work vehicle further includes a PTO transmission operation lever allowing a transmission operation to be performed on the PTO transmission mechanism, wherein the PTO transmission operation lever and the storage unit are provided in the vehicle body rear structure. | 03-20-2014 |
20140076103 | WORKING VEHICLE - According to one embodiment, a working vehicle includes: a main change speed mechanism configured to transmit a rotating power, generated by a power source; a first auxiliary change speed mechanism configured to transmit the rotating power, transmitted through the main change speed mechanism, to drive wheels; a second auxiliary change speed mechanism configured to transmit the rotating power to the drive wheels; a first lever configured to operate the first auxiliary change speed mechanism to perform a first auxiliary shift operation; and a second lever configured to operate the second auxiliary change speed mechanism to perform a second auxiliary shift operation, wherein: the first auxiliary change speed mechanism is activated when the second auxiliary change speed mechanism in a neutral state; and the second auxiliary change speed mechanism is activated when the first auxiliary change speed mechanism is in the neutral state. | 03-20-2014 |
