  • Patent number: 11724894
    Abstract: A judgment process of judging whether or not the movable linear module is located in the facing range is performed before the slider transfer operation of moving the slider from the fixed linear module to the movable linear module located in the facing range is performed. As a result, unless the movable linear module is judged to be located in the facing range, the slider transfer operation is performed after a preparation operation of moving the movable linear module into the facing range is performed. Therefore, the slider can be properly moved from the fixed linear module to the movable linear module.

  • Patent number: 11708802
    Abstract: A fuel management system to improve accuracy of calibration data to convert an output value of a fuel gauge into a remaining amount of fuel in a fuel tank includes a fuel tank mounted on a hull of a marine vessel, a fuel gauge to measure a liquid level position of fuel in the fuel tank, and a controller configured or programmed so that in a range where an output value of the fuel gauge changes, measurement reference points are set based on the output value of the fuel gauge. When supplying fuel to the fuel tank, the controller is configured or programmed to obtain calibration data showing a relationship between the output value of the fuel gauge and a remaining amount of the fuel in the fuel tank by comparing an amount of fuel supplied to the fuel tank at each of the measurement reference points and the output value of the fuel gauge at each of the measurement reference points.

  • Patent number: 11701999
    Abstract: A light emitting device for a leaning vehicle, including a pair of cornering lamps, including a first cornering lamp and a second cornering lamp, that emit light to form a single left-front light emission area and a single right-front light emission area, and a control device that controls light emission by the pair of cornering lamps based on a lean angle of the vehicle body. The control device is configured to cause a first quantity of light and a second quantity of light, which are respectively a quantity of light outputted from the at least one light source included in the first cornering lamp and in the second cornering lamp, respectively, to vary in accordance with the lean angle of the vehicle body, such that each of the single left-front light emission area and the single right-front light emission area becomes larger as the lean angle of the vehicle body increases.

  • Patent number: 11702300
    Abstract: The transfer operation of moving the slider between one fixed linear module and the movable linear module while locating the movable linear module in the facing range facing toward the one fixed linear module, out of the plurality of linear modules arranged in parallel, is performed. At this time, a judgement process of judging whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous is performed. If it is judged that the coordinate axes are not continuous, the transfer operation is performed while the speed control is executed for the slider. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the movable linear modules cannot be performed due to the discontinuity of the coordinate axes respectively set for the movable linear modules.
