  • Patent number: 8809496
    Abstract: It is an object of the present invention to provide a method for producing an 11-sugar sialylglycopeptide easily and with good yield and a high degree of purity on an industrial scale from defatted bird egg yolks. The present invention provides a production method of an 11-sugar sialylglycopeptide. More specifically, the present invention provides a production method of an 11-sugar sialylglycopeptide comprising: an extraction step of extracting defatted bird egg yolks with water or a salt solution to obtain a liquid extract of a glycopeptide, a precipitation step of adding the liquid extract to a water-soluble organic solvent to precipitate the glycopeptide, and a desalting step of desalting the precipitate.

  • Patent number: 6946095
    Abstract: The invention provides an internal filter with an improved filtering ability of removing particularly fine inclusion particles from molten aluminum or molten aluminum alloy. The internal filter includes an aggregate meshed member made of a refractory material and a coating layer formed on a surface of the aggregate meshed member. The coating layer contains a soda silicate that is able to be softened or viscous at a temperature of the molten aluminum alloy.

  • Patent number: 6171362
    Abstract: A method for refining molten Al alloy and a non-halogen based flux for refining molten Al alloy which make it possible to perform refining such as removal of gas and inclusions at a high reduction level, and are free from a problem that the flux remains in the molten Al alloy, wherein a refining flux is injected into molten Al alloy obtained by melting an Al raw material to refine the melt, thereafter, the resultant is supplied to a mold, so as to cast the Al alloy. At this time, alum is used as the refining flux.

  • Patent number: 5364449
    Abstract: A process for refining a crude material for copper or copper alloy which contains as impurity elements at least one species of Pb, Ni, Sb, S, Bi, and As in combination with at least one species of Sn, Fe, and Zn, which comprises the sequential steps of (1) melting a crude material for copper or copper alloy, (2a) increasing the oxygen concentration in the melt, thereby oxidizing Sn, Fe, and Zn into slag, (this step is carried out if the crude material contains as impurity elements at least one species of Sn, Fe, and Zn) (2b) adding to the melt at least one species selected from the group consisting of Fe, Fe oxide, Mn, and Mn oxide, thereby causing Pb, Ni, Sb, S, Bi, and As in the melt to slag in the form of compound oxide of Fe and/or Mn, (3) removing the thus formed slag from the melt, and (4) subjecting the melt to reduction.
