  • Patent number: 6548081
    Abstract: The present invention relates to a composite and a method for reducing post-operative adhesion of tissues. The composite includes a biocompatible, biodegradable support, and a water-insoluble hyaluronic acid derivative at the support. The hyaluronic acid derivative includes an N-acylurea that results from cross-linking by the reaction of hyaluronic acid with a multifunctional carbodiimide. Optionally, a monocarbodiimide also may be employed. A pharmaceutically-active molecule may be added to the N-acylurea derivative of hyaluronic acid. Although the composite includes material that prevents adhesion between tissues, in order to reduce the need for suturing when the composite is being used during a surgical procedure, a material that enhances adhesion of the composite to tissues may be applied to a surface of the composite.

  • Publication number: 20020164498
    Abstract: The present invention discloses a novel compound useful as the material for a red organic EL device. The novel compound is produced by connecting a benzene ring at the positions 2 and 3 of withdrawing group 2,5-dimethyl-4-(2,2-dicyano)pyrane, and connecting a conjugated donating group at position 5. Using this compound, the EL emission is shifted to the red spectral region, and a higher purity in color for red EL elements is obtained. The synthesis of the compound is easy and the product yield is improved compared to the prior art. Moreover, the red organic EL devices fabricated using the compound have properties that conform with existing NTSC standards.

  • Patent number: 6024887
    Abstract: A method for stripping an ion implanted photoresist layer from a substrate. There is first provided a substrate. There is then formed over the substrate an ion implanted photoresist layer. There is then treated the ion implated photoresist layer with a first plasma employing a first etchant gas composition comprising a fluorine containing species to form a fluorine plasma treated ion implanted photoresist layer. Finally, there is then stripped from the substrate the fluorine plasma treated ion implanted photoresist layer with a second plasma employing a second etchant gas composition comprising an oxygen containing species without the fluorine containing species. The ion implanted photoresist layer is stripped from the substrate without plasma induced damage to the substrate.

  • Patent number: 5740839
    Abstract: The present invention provides a flexible extension conduit, in which a basic unit includes a joint base, two joints, two ball valves, a sliding pipe, two dirt covers, a flat pipe, two damping collars and two embedded retainers, and so on. Therein the embedded retainer is placed in the caulking groove of the ball valve so that the caulking groove of the embedded retainer catches the catching rim in the caulking groove of the ball valve. The sliding pipe is put in the ball valve and welded a thrust collar at the smaller end to limit the sliding range of the sliding pipe in the ball valve, and the combined ball valve is located in the spherical bearing consisting of the joint base and the joint. When the earth crust moves or the temperature gets a great changing, the dirt cover can prevent the sand and the soil from seeping in, and the conduit can change the length and bend an angle in each section.
