Patents by Inventor Norimasa Noda

Norimasa Noda has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Implement and device for analysis
    Patent number: 7351375
    Abstract: The present invention relates to an analyzing implement (1) having a capillary for movement of a specimen liquid. The capillary has inner surfaces (21c, 32c) provided with a first and a second opposed electrodes opposed to each other. The implement (1) includes, for example, a substrate (20), a cover (40) and a spacer (30) between the substrate (20) and the cover (40). In this case, the capillary is provided by the substrate (20), the cover (40) and the spacer (30). Preferably, capillary forming surfaces (31c, 32c) of the spacer (30) are electrically conductive, in which case the surfaces (31c, 32c) provide the first and the second electrodes.

  • Ion activity-measuring device and method for producing the same
    Patent number: 6903335
    Abstract: The ion activity-measuring device of the present invention is provided with a hydrophobic bridge of which portion contacting with a liquid reservoir is hydrophilic. The hydrophobic bridge is made of, for example, at least one selected from the group consisting of polyester, nylon, polypropylene, rayon and polyethylene, and is produced by treating a portion contacting with the liquid reservoir with a spreading accelerator. The spreading accelerator is at least one selected from the group consisting of a surfactant and a hydrophilic polymer. There is also provided a method for producing the above ion activity-measuring device, comprising embedding nonwoven fabric in the cover plate to bond the nonwoven fabric to the cover plate.
