  • Publication number: 20220156725
    Abstract: A processor may assign a bridging blockchain client. The bridging blockchain client may link a first system to a second system. The first and second systems may be on one or more blockchains. The processor may identify that an exchange has been initiated. The processor may generate one or more assets in response to the exchange. The processor may process the exchange. The processing of the exchange may include the bridging blockchain client accepting a probability of failure of the exchange.

  • Publication number: 20110114981
    Abstract: In a light emitting display apparatus, excellent color reproducibility and high luminance for an emission color having a low color purity and low emission efficiency are realized. An electroluminescent layer whose color purity and emission efficiency are to be improved is stacked as a first layer on a substrate, and is interposed between a reflective electrode layer and a semi-reflective electrode, and then light extracted from the electroluminescent layer is intensified by interference between a reflective surface in the reflective electrode layer and a reflective surface in the semi-reflective electrode.

  • Publication number: 20050062907
    Abstract: According to the invention, after a transparent electrode is vapor-deposited over the entire color-filter side surface, a non-conductive film is laid where the presence of the transparent electrode causes problems. That is, this non-conductive film is formed of the same material and at the same time as an alignment regulation film over the whole or a part of the area where exposure of the transparent electrode causes problems so as to seal the transparent electrode there. This makes it possible to prevent the above-mentioned problems caused when the transparent electrode is vapor-deposited over the entire surface, and simultaneously to enhance the patterning accuracy up to the exposure accuracy (of the order of several ?m) of proximity or the like so as to realize a product with a narrow frame.

  • Patent number: 5948317
    Abstract: A liquid crystal composition includes at least one fluorine-containing mesomorphic compound (a) having a fluorocarbon terminal portion and a hydrocarbon terminal portion, and at least one optically active compound (b) having an optically active cyclic group and a terminal alkyl group free from a perfluorocarbon atom. The compound (a) and the compound (b) are mutually soluble readily to form a homogeneous liquid crystal composition. The liquid crystal composition shows a layer structure of so-called bookshelf or a layer structure having a small inclination angle (closer to bookshelf structure). The liquid crystal composition is useful in improving response characteristics and display characteristics, particularly a contrast ratio, of a liquid crystal device using the liquid crystal composition.
