  • Publication number: 20210064036
    Abstract: To make it possible to correct a current position detected by an autonomous traveling work machine to the correct position with a simple configuration. A robot lawn mower includes a first position detecting unit for detecting a current position by using odometry and a second position detecting unit for detecting a current position by using an image capture. When position detection accuracy of both of the first and second position detecting units decreases to less than or equal to a predetermined value, the robot lawn mower is controlled to travel to either of zones Z1 and Z2 in which the position detection accuracy of the second position detecting unit is relatively high, and when the robot lawn mower moves to either of the zones Z1 and Z2, a current position used for autonomous traveling is corrected to the current position detected by the second position detecting unit.

  • Patent number: 10927713
    Abstract: An intake air cooling device includes a water supply line and a heat pump device. The water supply line is configured to send water to a waste heat recovery boiler which is configured to generate steam using heat of an exhaust gas from a gas turbine. The heat pump device is configured to transfer heat of air suctioned by the gas turbine to water flowing through the water supply line and thereby cool the air while heating the water.

  • Patent number: 10844753
    Abstract: A boiler including one or more evaporators, an economizer, and a low-temperature heat exchanger. The economizer is located on a downstream side of the most downstream evaporator which is an evaporator at the most downstream side among the one or more evaporators. The low-temperature heat exchanger is located on the downstream side of the economizer, has an inlet for receiving water from the outside, and is configured to heat the water introduced from the inlet and sent to the economizer with the combustion gas.

  • Publication number: 20200332681
    Abstract: The present invention provides a gas turbine plant that includes a gas turbine, an exhaust heat recovery boiler, and a water supply system that is configured to supply water to the exhaust heat recovery boiler. The exhaust heat recovery boiler has an evaporator that uses an exhaust gas to heat water, thereby generating steam, and a reheater that is configured to heat steam from outside with the exhaust gas passing through the evaporator. The water supply system has a water supply line that is configured to supply water from a water supply source to the exhaust heat recovery boiler, and a supplied water temperature regulator that is configured to regulate the temperature of the supplied water, which is the water flowing along the water supply line.

  • Patent number: 10336173
    Abstract: The invention provides a mounting structure for a power unit of a utility vehicle. The mounting structure includes a pair of left and right front support portions supporting a front end of the power unit, and a rear support portion supporting a rear end of the power unit. The front support portions and the rear support portion are disposed to cause a centroid of a triangle connecting the front support portions and the rear support portion to agree with a centroid of the power unit in a planar view of the power unit.

  • Publication number: 20190178111
    Abstract: Provided is a plant that includes: a boiler (30); a device connected to the boiler (30); a water supply source (41) that is configured to pool water; a water supply line (44) that supplies water from the water supply source (41) to the boiler (30); a cooler (50, 60g, 60s, 70g, 70s, 80) that transfers heat from a medium to be cooled to supply-water (W), which is the water flowing along the water supply line (44); a thermometer (59, 69, 79, 89) that determines a temperature of the medium to be cooled or the supply-water; and a temperature regulator (53, 62, 72, 82) that is configured to regulate the temperature of the medium to be cooled on the basis of the temperature determined by the thermometer (59, 69, 79, 89).
