  • Patent number: 10135002
    Abstract: One objective of the present invention is to provide an organic EL element which is suppressed in change in the resistance of a light emitting layer after passing a current therethrough for a long period of time, thereby having good emission spectrum chromaticity, and which is suppressed in change in the emission characteristics over time. Another objective of the present invention is to provide a lighting device and a display device, each of which uses the organic EL element. An organic electroluminescent element of the present invention is provided with a pair of electrodes and one or more organic layers that are arranged between the pair of electrodes, and is characterized in that one or more layers among the organic layers contain a compound that has a structure represented by general formula (1).

  • Patent number: 10105678
    Abstract: An oxygen adsorbent which can be manufactured at a low cost, and an oxygen manufacturing equipment and an oxygen manufacturing method which are capable of producing oxygen-enriched gas at a low cost by using the oxygen adsorbent are provided. The oxygen adsorbent comprises at least an oxide of a perovskite structure. The oxide is represented by a compositional formula of Sr1?xCaxFeO3??, wherein 0.12?x?0.40, 0???0.5. Since this oxide does not include La and Co included in a conventional oxygen adsorbent, it can be manufactured at a low cost.
