20090313861 | Working vehicle - In a working vehicle in which a backhoe support frame for reinforcing is provided in a rear end portion of a vehicle body frame, and a transmission case is mounted on a rear portion of the vehicle body frame so as to be close to the backhoe support frame, each of support brackets provided in an outer side surface of a rear portion of each of main frames constructing the vehicle body frame so as to protrude outward is connected to a protruding end portion protruding to rightwardly and leftwardly relative to each of lower brace members in a reinforcing plate supporting a lower surface of the transmission case in a state in which a rear axle case protruding outward from the right and left side surfaces of the transmission case is sandwiched from upper and lower sides, in order to dissolve a risk that a load generated at a time of traveling in a backhoe installed state or at a time of an excavating work by the backhoe is propagated to the transmission case. | 12-24-2009 |
20090313862 | Working vehicle - A working vehicle in accordance with the present invention is provided with an engine mounted on a front portion of a vehicle body frame constructing a traveling vehicle body, a backhoe arranged on a rear portion of the vehicle body frame, a mower device arranged below the vehicle frame, a seating detecting means detecting a seating of an operator in a control seat on the traveling vehicle body, an engine stop mechanism stopping the engine, and a shift control means for controlling so as to increase and decrease forward and backward moving speeds of the traveling vehicle body. Further, in consideration for a safety at a time of an excavating work by the backhoe, the structure is made such that the engine stop mechanism is actuated at a time of operating the shift control means in the case that the seating detecting means is in an on state, and the seating detecting means is retained to the on state regardless of the seating of an operator in the case that the control seat is directed backward. | 12-24-2009 |

20120210742 | AIR-CONDITIONING APPARATUS - To obtain an air-conditioning apparatus that appropriately determines the state of stagnating refrigerant in a compressor, and suppresses power consumption while the air-conditioning apparatus is not in operation. When a compressor temperature change rate is determined to be higher than a refrigerant temperature change rate, a controller identifies that liquid refrigerant in a lubricant oil in a compressor has been totally gasified, stops energizing a motor unit, and ends a heating operation of the compressor. | 08-23-2012 |
20130152609 | HEAT PUMP DEVICE, HEAT PUMP SYSTEM, AND A CONTROL METHOD OF THREE-PHASE INVERTER - An adder adds a phase θplus, which is n times a size of 60 degrees, to a phase output from a phase switching unit and outputs the phase as a voltage command phase θ. A voltage generation unit generates voltage command value based on the voltage command phase output by the adder and outputs the command value. A drive-signal generation unit, based on an output from the voltage generation unit generates drive signals corresponding to respective switching elements of an inverter, and outputs respective generated drive signals to the corresponding switching elements of the inverter, and generates a high-frequency AC voltage in the inverter. | 06-20-2013 |
20130180273 | HEAT PUMP DEVICE, HEAT PUMP SYSTEM, AND METHOD FOR CONTROLLING THREE-PHASE INVERTER - A selection unit switches between a phase θp and a phase θn different from the phase θp substantially by 180 degrees, and outputs one of them in synchronization with a carrier signal. A voltage-command generation unit generates and outputs three-phase voltage command values Vu*, Vv* and Vw* based on the phase outputted by the selection unit. A PWM-signal generation unit generates three-phase voltage command values Vu*′, Vv*′ and Vw*′ by correcting the three-phase voltage command values Vu*, Vv* and Vw* outputted by the voltage-command generation unit according to a predetermined method, and generates six drive signals corresponding to switching elements of the inverter based on the three-phase voltage command values Vu*′, Vv*′ and Vw*′ and the carrier signal. The PWM-signal generation unit outputs the generated drive signals to the corresponding switching elements of the three-phase inverter, to cause the inverter to generate a high-frequency AC voltage. | 07-18-2013 |
20130199224 | AIR-CONDITIONING APPARATUS - While a compressor is stopped, a change rate of a refrigerant temperature per predetermined time is calculated on the basis of a value detected by a refrigerant temperature sensor, and a heating amount from a compressor heating unit to the compressor is made proportional to the change rate of the refrigerant temperature. | 08-08-2013 |
