  • Patent number: 10710432
    Abstract: A vehicle air conditioner has a compressor, a radiator, a pressure reducer, a cooling heat exchanger, a temperature detector, and a prohibition request output part. The compressor draws and discharges a refrigerant. The radiator dissipates heat of the refrigerant. The pressure reducer decompresses and expands the refrigerant. The cooling heat exchanger cools an air blown into a vehicle compartment. The temperature detector detects a temperature of the cooling heat exchanger. The prohibition request output part outputs a request, which prohibits the idle stop control, to an idle stop controller when the engine is operated. The request prohibits the idle stop control until the temperature of the cooling heat exchanger falls to a temperature being enough cool to cool the air and a required cooling time elapses. The required cooling time is estimated to be required to make a passenger feel cool by the air.

  • Patent number: 10705195
    Abstract: A distance measuring apparatus measures a distance to a target from a plurality of directions, and includes sensors having identical two-dimensional scan type configurations that launch a laser beam and receive reflected light from the target by a multi-segment light receiving element, and a processor. The processor performs a process including specifying a receiving part of the multi-segment light receiving element of a first sensor, that receives a second laser beam launched from a second sensor in a state in which the target is non-detectable by the first sensor, adjusting a phase in a vertical scan direction of the second laser beam with respect to that of a first laser beam launched from the first sensor, until the receiving part no longer receives the second laser beam, and integrating range images from the first and second sensors after the phase is adjusted.

  • Patent number: 10431485
    Abstract: Before a moving member that moves along a moving path stops, an article transport facility starts protrusion control by which a moving support portion that is provided on the moving member is moved so as to protrude toward a fixed support portion, and thereafter the article transport facility appropriately determines whether or not to continue the protrusion control. Upon the moving member reaching a protrusion start position, the protrusion control is started so that the moving support portion is moved to protrude, even if the moving member has not stopped. After the moving member has reached a position at which a detection unit that is fixed to the moving member can detect a detection target member that is provided on the fixed support portion, the execution of the protrusion control is continued as long as the detection unit is detecting the detection target member.
