  • Biosensor and method for manufacturing same
    Patent number: 7727367
    Abstract: The present invention provides a biosensor that can be used for easy and quick quantitative analysis of a specific component in a sample with high precision and a method for manufacturing such a biosensor. The present invention also provides a biosensor that can be used for a highly precise quantitative analysis after an extended period of storage, specifically, a biosensor with excellent storage stability, and a method for manufacturing such a biosensor. The present invention relates to a biosensor comprising an electrically insulating substrate (1); an electrode (2) having a working electrode (21) and a counter electrode (22) formed on the substrate; and a reaction part (4) that is adhered to one end of the electrode (2); the reaction part (4) being mainly composed of a hydrophilic polymer comprising an oxidoreductase, an electron acceptor, fine crystalline cellulose powder, and hydrophilic and hydrophobic segments.
    Type: Grant

  • Process and apparatus for forming laminate by thermocompression bonding
    Patent number: 4861409
    Abstract: The invention provides a process and an apparatus for laminating a film 1 and a film 2 by thermocompression bonding.When the film 1 and the film 2 are laminated by thermocompressing bonding with a heat roll 3 and a pressure roll 4, the film 1 is guided onto the heat roll 3 via a feed angle adjusting roll 5 for automatically adjusting the distance of contact of the film with the heat roll 3, and/or the laminate film formed by thermocompression bonding is released from the heat roll 3 by being passed over a discharge angle adjusting roll 8 for automatically adjusting the distance of contact of the laminate film with the heat roll.
