  • Publication number: 20020012666
    Abstract: A method for increasing weight gain and feed efficiency in a subject animal, whether that subject animal is healthy or suffering from a disease resulting in weight loss, such as cachexia. The method consists of the administration of an effective amount of hyperimmunized egg product.
    Type: Application

  • Patent number: 6340615
    Abstract: A method of connecting a trench capacitor in a dynamic random access memory (DRAM) cell. First, trenches are formed in a silicon substrate using a masking layer including a pad nitride layer on a pad oxide layer. Trench capacitors are formed in the trenches. A buried strap is formed in each trench on the capacitor. The nitride pad layer is pulled back from the trench openings, exposing the pad oxide layer and any strap material that may have replaced the pad oxide layer around the trenches. The straps and trench sidewalls are doped to form a resistive connection. During a subsequent shallow trench isolation (STI) process, which involves an oxidation step, the exposed strap material on the surface of the silicon surface layer forms oxide unrestrained by pad nitride without stressing the silicon substrate.

  • Patent number: 6326475
    Abstract: The invention is an acid-chitosan complex which is made up of chitosan, a sufficient amount of one or more acids, and an effective amount of water. This acid-chitosan is water-soluble in a dry form. A further aspect of this invention is various methods for producing such a water-soluble acid-chitosan complex and methods for using this acid-chitosan complex, particularly for reducing fat absorption in an animal.

  • Patent number: 6323535
    Abstract: A fuse for semiconductor devices, in accordance with the present invention, includes a cathode including a first dopant type, and an anode including a second dopant type where the second dopant type is opposite the first dopant type. A fuse link connects the cathode and the anode and includes the second dopant type. The fuse link and the cathode form a junction therebetween, and the junction is configured to be reverse biased relative to a cathode potential and an anode potential. A conductive layer is formed across the junction such that current flowing at the junction is diverted into the conductive layer to enhance material migration to program the fuse.
