Abstract: A biosignal electrode that includes a substrate having first and second opposed main surfaces; a conductive material pattern on the first main surface of the substrate, the conductive material pattern defining a plurality of open spaces extending through the conductive material pattern and exposing the first surface of the substrate therethrough; and a biocompatible glue material within the plurality of open spaces of the conductive material pattern.

Abstract: A surface treated steel strip according to the present invention includes: a base steel sheet; a zinc phosphate coating film layer made of needle zinc phosphate crystals which are formed in an island shape on a surface of the base steel sheet; and a lubricating coating film layer covering the surface of the base steel sheet and a part of the zinc phosphate coating film layer, and containing at least a lubricating component, in which an area ratio of the zinc phosphate crystals exposed from a surface of the lubricating coating film layer is 25% to 90%.

Abstract: To provide a water-based lubricant for plastic working excellent in moisture absorption resistance and corrosion resistance, with which degradation in lubricating performances such as lubricity, workability and seizure resistance may not occur even under high-temperature/high humidity environments. A water-based lubricant for plastic working, comprising a resin component containing a copolymer or homopolymer of monomers having an ethylenically unsaturated bond, including at least maleic anhydride (A), an inorganic component (B), and a solid lubricating component (C), wherein maleic anhydride moieties of the resin component (A) are blocked with a nitrogen-containing compound at a blocking ratio of 10 to 80%, and unblocked maleic anhydride moieties are neutralized with an alkaline component at a degree of neutralization of 40 to 100%.

Abstract: An article of magnesium or its alloy having a surface layer containing magnesium condensed phosphate and magnesium phosphate, which can be produced by treating an article of magnesium or its alloy with a treating liquid containing 1,000 to 20,000 ppm of alkaline metal ions, 1,000 to 50,000 ppm of condensed phosphate ions, and 100 to 20,000 ppm of borate ions, and having pH of at least 8. The treated article has good corrosion resistance, and a coating can be formed on the surface of the article with good adhesion.
