|20150252820||HYDRAULIC DRIVING APPARATUS FOR WORKING MACHINE - Provided is a hydraulic driving apparatus including a calculation section calculating a temporary target engine rotation speed corresponding to an engine operation amount, a calculation section calculating a temporary target pump displacement volume based on first-control and second-control target pump displacement volumes corresponding to an actuator operation amount and a pump load pressure, and a command section calculating a final target engine rotation speed and a final target pump displacement volume to output commands. The command section calculates a target pump discharge amount from the temporary target engine rotation speed and the temporary target pump displacement volume, sets the final target pump displacement volume to one larger than the temporary target pump displacement volume, and sets the final target engine rotation speed to one being lower than the temporary target engine rotation speed and allowing a pump discharge amount equivalent to the target pump discharge amount to be obtained.||09-10-2015|
|20150247439||REDUCTANT CONTAINER - A reductant container having: a tank main body that accommodates a reductant; a heating member disposed in the tank main body and configured to generate heat so as to increase a temperature of the reductant; a covering member covering the heating member and having an inflow portion, the inflow portion allowing some of the reductant to flow into the covering member; a reductant supply pipe through which the reductant in the covering member is supplied to the outside of the tank main body; and a temperature measuring unit having a temperature sensor disposed in the covering member to sense a temperature of the reductant, the temperature measuring unit determining the temperature sensed by the temperature sensor, wherein the covering member has an upper wall covering the heating member from above, the upper wall having a lower surface that is inclined so as to be raised toward the temperature sensor.||09-03-2015|
