  • Patent number: 10377219
    Abstract: A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.

  • Patent number: 10315534
    Abstract: Provided is a work vehicle having a rollover protection structure (ROPS) around a driver's seat which is switchable between a front seating posture and a rear seating posture. A locking mechanism locks the driver's seat to the rear seating posture. The locking mechanism includes a hook provided on the driver's seat side, a hook rod disposed between a left strut and a right strut and engageable with the hook when the driver's seat is switched to the rear seating posture, and a rod bracket for supporting the hook rod. The rod bracket is provided separately from the left strut and the right strut.

  • Patent number: 9313272
    Abstract: An information processor receives a changed content check request on information managed by a user of a different system from a user terminal and a first condition is stored, the first condition being included in the check request and specifying a check target. A second condition specifying a changed content to be retrieved from among changed contents on the information managed by the user of the different system is received from the user terminal. An information-changed content check request is transmitted in which the stored first condition is specified to a converter that performs protocol conversion. A changed content check result is acquired from the converter and stored, the result being returned to the converter by the user terminal of the different system. The stored check result is checked against the second condition, and the check result that matches the second condition is returned to the user terminal.

  • Publication number: 20110088101
    Abstract: It is checked whether or not information requested in an information request is present in a message sharing/storing unit which stores information provided from an information provider and accessibility information setting an information requester which is allowed to access the information. It is also determined whether or not the information requester can access information requested in an information request message based on the accessibility information. When it is determined that the information requested in the information request message is already registered in the message sharing/storing unit and the information requester can access the information, information on a request-reply-message to the information requester is created based on the information in the message sharing/storing unit.

  • Patent number: 5396555
    Abstract: A power and signal transmission system performs a transmission of a power from a first communication device to a second communication device via a transmission path as well as a transmission of a signal between the first and second communication devices via the transmission path. The first communication device includes a high voltage power source and a first pair of active inductances each having a low DC impedance and a high AC impedance, through which the power from the high voltage power source is supplied to the transmission path, and the second communication device includes a DC/DC converter and a second pair of active inductances each having a low DC impedance and a high AC impedance, through which the power transmitted via the transmission path is supplied.
