  • Patent number: 10903453
    Abstract: A highly reliable light-emitting device is provided. Damage to an element due to externally applied physical power is suppressed. Alternatively, in a process of pressure-bonding of an FPC, damage to a resin and a wiring which are in contact with a flexible substrate due to heat is suppressed. A neutral plane at which stress-strain is not generated when a flexible light-emitting device including an organic EL element is deformed, is positioned in the vicinity of a transistor and the organic EL element. Alternatively, the hardness of the outermost surface of a light-emitting device is high. Alternatively, a substrate having a coefficient of thermal expansion of 10 ppm/K or lower is used as a substrate that overlaps with a terminal portion connected to an FPC.

  • Patent number: 10621800
    Abstract: At least one embodiment may provide a remote server that can determine occurrence of an abnormal condition in a power transmission system without using a threshold value in advance. There may be provided a remote server that receives operating and non-operating information of a working unit, information on a working date, information on a traveling speed, and information on a load factor of an engine, respectively from a combine harvester. The remote server calculates for each predetermined period an average of the engine load factor while the traveling speed is at or above a predetermined traveling speed with all working units in non-operation. If the average during a predetermined period is in a status of a predetermined difference from the average up to the predetermined period, the remote server determines that a moving power transmission mechanism of a traveling system of the combine harvester is in an abnormal condition.
