  • Patent number: 7857470
    Abstract: Provided is a light reflecting plate capable of reducing glare of reflected light while maintaining high light reflectance by regular reflection. The light reflecting plate includes a base, a light reflecting layer that is formed on the base and made of silver or silver alloy, or aluminum or aluminum alloy, in which arithmetic average roughness (Ra) is 0.10 to 0.30 ?m and arithmetic average waviness (Wa) is 0.30 to 2.50 ?m on a surface of the light reflecting layer.
    Type: Grant

  • Patent number: 6551721
    Abstract: A purpose of the present invention is to provide a surface treated steel sheet for a battery container having an excellent anti-alkaline characteristic and a performance for maintaining a discharging level for a long time, a battery container and a product method thereof. In the present invention, after forming a nickel-bismuth alloy layer on a steel sheet, the steel sheet is thermally treated at 300° C. to 650° C. in an inactive gas or a deoxidizing gas for 240 to 600 min so that an iron-nickel diffused layer and nickel-bismuth diffused layer are formed at each boundary surface. A battery is produced by utilizing a battery container made of a steel sheet on which one or more than layers selected from a group of an iron-nickel diffused layer, a nickel layer, a nickel-bismuth diffused layer, an iron-nickel-bismuth alloy layer is formed on the steel sheet.
