  • Publication number: 20200373586
    Abstract: Provided are a porous metal body that is excellent in terms of corrosion resistance and that is suitable for a collector for batteries such as lithium-ion batteries, capacitors, or fuel cells; and methods for producing the porous metal body. A production method includes a step of coating a porous nickel body with an alloy containing at least nickel and tungsten or a metal containing at least tin; and a subsequent step of a heat treatment. Another production method includes a step of forming a nickel-plated layer on a porous base and then continuously forming an alloy-plated layer containing at least nickel and tungsten or tin, a step of removing the porous base, and a step of reducing metal. Such a method can provide a porous metal body in which tungsten or tin is diffused in a porous nickel body or a nickel-plated layer.

  • Patent number: 10524401
    Abstract: A component mounting machine moves a mounting head from a supply position P1 to each of mounting positions P3 and P4 of a circuit board CB via an imaging position P2. Further, the component mounting machine performs control such that the mounting head moves in a direction of movement at the time of imaging that is either of an X-axis direction or a Y-axis direction when passing through the imaging position P2. The component mounting machine determines the direction of movement at the time of imaging, according to a first X-axis distance Lx and a first Y-axis distance Ly from the imaging position P2 to each of the mounting positions P3 and P4.
