  • Publication number: 20240196735
    Abstract: The present disclosure relates to an organic compound including at least one carbazolyl moiety fused with an alicyclic or hetero alicyclic ring and linked to directly or via a linker to a triazine moiety and at least one blocking moiety linked the triazine moiety, an organic light emitting diode and an organic light emitting device including the organic compound. The organic compound can implement high luminous efficiency as enhancing delayed fluorescent property, minimize reduction of the luminous lifespan caused by substituent degradation, and can secure high triplet energy level owing to no conjugation extensions. The organic light emitting diode and the organic light emitting device using the organic compound can have beneficial luminous efficiency and the luminous lifespan.

  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Patent number: 9327806
    Abstract: Provided is an arctic drill ship in which a weather tight structure protecting a drill floor and a drilling work area from outside air is coupled to a side strake around the drilling work area. It is possible to economically and easily manufacture the weather tight structure which minimizes the influence of outside air on the drilling operation in the polar regions, and it is possible to efficiently support the hull longitudinal strength and the weather tight structure with the use of the side strake structure solely. Therefore, a structure which may cause a disturbance in the drilling work area is minimized, and it is unnecessary to install a separate structural reinforcement part for a drilling workspace in the polar regions. In addition, the drilling workspace in the polar regions can be effectively ensured, and a spatial limitation in an upper portion of a moonpool can be solved.
