  • Patent number: 11944948
    Abstract: Disclosed is a composite for forming a coacervate interfacial film. The composite for forming the coacervate interfacial film contains a cationic hectorite nanoplate-shaped particle structure containing a hectorite nanoplate-shaped particle and a cationic surfactant coupled to a surface of the hectorite nanoplate-shaped particle, and an anionic cellulose nanofibril containing an anionic functional group in at least a portion thereof, in which the composite may form the coacervate interfacial film at an interface of an oil phase and a water phase through electrostatic interaction between the cationic surfactant and the anionic functional group.

  • Publication number: 20090251050
    Abstract: An organic light emitting display device includes a substrate having a pixel unit for emitting light, a metal cap facing the substrate, a flexible printed circuit board coupled to the pixel unit of the substrate and arranged in a manner that the metal cap is arranged between the substrate and the flexible printed circuit board, and an adhesive member formed between the flexible circuit board and the metal cap. The adhesive member fills the entire space formed between the flexible circuit board and the metal cap. The construction of the adhesive member removes noise that can be generated during the operation of the organic light emitting display device.

  • Patent number: 6801121
    Abstract: A paging system separately transmits high capacity data through at least two paging channels of limited transmission rates in order to provide the high capacity data in real-time. A pager receives and processes the paging frequency signal transmitted through at least two channels, thereby generating regenerated data not to be separated.
