  • Publication number: 20200017096
    Abstract: To provide a power regeneration system for a working vehicle that can effectively use a regenerative electric energy. A first electric circuit for supplying an electric power generated by the first generator to a traveling motor, a voltage detector for detecting an actual voltage of the first electric circuit, a second electric circuit for supplying an electric power generated by a second generator to an auxiliary device, a step-down device connected to the first electric circuit and the second electric circuit, and a controller are provided. The controller estimates the voltage of the first electric circuit after a predetermined time has elapsed from the present time, based on information on a traveling state of a work vehicle and the actual voltage detected by the voltage detector, and outputs a drive command to the step-down device when the estimated voltage is equal to or more than a threshold.

  • Patent number: 8248629
    Abstract: A job managing section acquires an operational status of a standby print job when a determination that a job having been accepted by a job accepting section is a reserved low-key print setting job is made, as a result of a determination by a reserved setting determining section, and also allocates a printout for the reserved low-key print setting job to an available time slot based on the acquired operational status. As a result, the printout for the reserved low-key print setting job can be executed in an available time slot which is different from a time slot for the standby print job. Accordingly, mixing of printed sheets related to a plurality of print jobs can be prevented as much as possible, and a contribution to an improvement in convenience at the user-side can be made.
