  • Patent number: 8966918
    Abstract: A wheel loader is provided with a cab, an air conditioning unit, a cooling fan which has a condenser and a compressor, an air conditioning switch which receives the operation or non-operation of the compressor, a temperature setting portion which sets a set temperature inside the cab, a room temperature sensor which detects a room temperature inside the cab, and a controller. In a case where the air conditioning switch is operated and the room temperature is higher than a set temperature, the controller maintains the rotation amount of the cooling fan at a limited rotation amount or more.

  • Patent number: 8800704
    Abstract: A wheel loader includes a vehicle body frame, an engine, a working unit a fuel tank and a cooling device. The fuel tank is attached to a bottom surface of a rear part of the vehicle body frame, and has a rear end surface slanted obliquely rearwards from up to down. The cooling device is configured to release heat of a coolant flowing through an inside thereof. The cooling device is supported by the rear part of the vehicle body frame. A bottom end portion of the cooling device is opposed to and separated away from a rear end surface of the fuel tank at a predetermined distance in a back-and-forth direction. A bottom surface of the cooling device is positioned lower than a top surface of a rear end portion of the fuel tank.

  • Publication number: 20050272604
    Abstract: The present invention provides a heat-sensitive recording material in which heat-sensitive recording layers are provided on a support, the heat-sensitive recording layers each containing, as an emulsified dispersion, an electron-accepting compound which reacts with an electron-donating dye precursor to form color, or a coupler compound which reacts with a diazonium salt to form color. At least one layer of the heat-sensitive recording layers contains the emulsified dispersion having a volume average particle size of less than 0.18 ?m. The volume average particle size of the emulsified dispersion is preferably less than 0.5 relative to the volume average particle size of the microcapsules encapsulating the electron-donating dye precursor or the diazonium salt.
