This invention provides a polymer rechargeable battery, which is obtained by integrally holding a separator, which comprises a polymer and a plasticizer, between positive and negative electrodes and then replacing the plasticizer with an electrolyte solution. The positive and negative electrodes are provided with current collectors obtained by etching metal-foil base materials, respectively. This invention also provides such current collectors. The polymer rechargeable battery according to this invention is excellent in impedance characteristic, load characteristic and the like.

Current collectors for battery

A gene encoding a protease derived from human serum and having an activity to convert single-chain hepatocyte growth factor (HGF) into active two-chain HGF and a method of producing the protease by the use of said gene are provided. A method of producing a precursor protein of said protease is also provided.

Hepatocyte growth factor activating protease and gene encoding the

A laminated sheet for a lid of a container for instant food cooked with hot water, comprising a metallic foil and a synthetic paper affixed to the metallic foil is disclosed. Self sealing of the container is achieved after the lid is partly peeled and hot water is poured into the container.

Laminated sheet for a lid of a container for instant food cooked with

A lid which is to be heat-sealed on a container, including a laminated sheet composed of a base layer, an adhesive layer, a metallic layer, and a heat-sealable resin layer, in which the base layer includes a single layer of a stretched resin film having many microvoids or a laminate containing at least the stretched resin film, the lid having an indication of the direction of stripping, including a lug provided at the periphery thereof or a print thereon, in such a manner that the indicated direction of stripping should be set within a range of .+-.45.degree. with respect to the direction of greatest thermal expansion coefficient of the base layer when heated from 30.degree. C. up to 80.degree. C. at a rate of temperature rise of 10.degree. C./min for 5 minutes. When hot water is poured into a container with the lid partly stripped, the lid is heated by the steam to close the container without assistance.

Lid of container and container for instant foods using the same

A novel water-soluble enzyme protein being composed of three heterogeneous subunits and having nitrile hydratase activity was separated and purified from the bacterium of genus Rhizobium. The nucleotide sequence of the gene encoding the protein was determined; using the transformant transformed with the expression vector having the nucleotide sequence, the protein was expressed; by reacting the transformant with a nitrile in a culture broth, the corresponding amide was produced. Via the use of a culture broth containing the transformant described above or the protein itself, a nitrile can be efficiently converted into the corresponding amide.
