  • Publication number: 20240079575
    Abstract: Provided is a secondary battery including a negative electrode, a positive electrode, a separation layer in contact with an active material-containing layer of the negative electrode, and an aqueous electrolyte. A first concentration corresponding to a first metal concentration represented by Equation 1 (first metal concentration=atomic concentration of Hg, Pb, Zn, and/or Bi/sum of atomic concentrations of elements B to U in periodic table, excluding carbon and oxygen) in a boundary region between the active material-containing layer and the separation layer is 2% or more and 8.2% or less. A ratio of the first concentration to a second concentration corresponding to the first metal concentration represented by Equation 1 in the active material-containing layer excluding the boundary region is 2.5 or more and less than 4.

  • Patent number: 7219893
    Abstract: A gaming machine includes a liquid crystal display having a liquid crystal panel and a light guiding plate placed at the rear of the liquid crystal panel and formed with a light deflection pattern for guiding light emitted from illumination means into the liquid crystal panel, and a variable display device placed at the rear of the liquid crystal display and having a plurality of reels provided in a row. Parts of the light guiding plate to which the reels are opposed are made light transmission areas. The light guiding plate is formed with a first light deflection pattern on the periphery of the light transmission areas and is formed with a second light deflection pattern in a portion more distant from the light transmission areas than the first light deflection pattern. The first light deflection pattern is denser than the second light deflection pattern.
