  • Patent number: 6291081
    Abstract: A process for producing an electrodeposited copper foil with its surface prepared, comprising the steps of: subjecting an electrodeposited copper foil having a shiny side and a matte side whose average surface roughness (Rz) is in the range of 2.5 to 10 &mgr;m to the first mechanical polishing so that the average surface roughness (Rz) of the matte side becomes 1.5 to 6 &mgr;m; and subjecting the matte side having undergone the first mechanical polishing to at least one further mechanical polishing so that the average surface roughness (Rz) of the matte side becomes 1.0 to 3.0 &mgr;m. The protrudent parts of the matte side are selectively polished by the first mechanical polishing, and the surface having undergone the first mechanical polishing is further subjected to the second and any ensuing mechanical polishings under milder conditions. Thus, a highly planar polished face with excellent surface properties can be obtained.

  • Patent number: 5672692
    Abstract: A human myelomonocyte interferon-gamma having a novel polypeptide and carbohydrate chain structure is produced by propagation of an established human myelomonocyte in vitro or after being implanted in a non-human warm-blooded animal or in a diffusion chamber placed inside or outside the body of the animal. The human myelomonocyte may be contacted with an inducer during propagation. A monoclonal antibody specific to the human myelomonocyte interferon-gamma is produced by immunizing a non-human warm-blooded animal with purified human myelomonocyte interferon-gamma as an antigen, recovering an antibody producing cell from the animal and fusing the cell with a myeloma cell to produce a hybrid capable of producing the monoclonal antibody. The human myelomonocyte interferon-gamma can be purified by chromatography with an immobilized anti-human myelomonocyte interferon-gamma antibody such as the monoclonal antibody.

  • Patent number: 5622859
    Abstract: Disclosed is an alkali-treated bagasse prepared by softening a bagasse with calcium oxide together with or without sodium hydroxide while preventing the substantial decomposition of cellulose and hemicellulose, a bagasse feed and a fermented bagasse feed prepared from the alkali-treated bagasse, and their preparations and uses as well as bacteria for fermenting the alkali-treated bagasse. These bagasse and bagasse feeds save sugar-refinery industries from the difficulties to treat bagasse deemed as an unutilized industrial waste, and livestock farming industries from the shortage of roughage, and further is extremely significant in agriculture, industries of sweetening products, feed industries and livestock product processors. A bacterium strain particularly useful for the fermentation is Enterococcus faecium FERM BP-4504.
