  • Patent number: 11590888
    Abstract: A lens includes an incident surface through which outgoing light enters the lens, the incident surface being formed at a portion opposed to a light source, and an emission surface through which incident light incident on the incident surface exits from the lens. The incident surface refracts outgoing light in a direction away from an optical axis of outgoing light, along a direction orthogonal to the optical axis. The emission surface refracts incident light in a direction away from a centerline of incident light, along a direction orthogonal to the centerline.

  • Patent number: 4934440
    Abstract: A mold surface treatment process comprises: providing a fluidized bed of a treating powder; holding the mold in the fluidized bed to fill up the depressions of the mold surfaces with the treating powder by employing a surface treating member for pushing the treating powder into the depressions; and taking the mold out of the fluidized bed. The mold surface treatment allows to make molten metal less likely penetrate into the walls of mold, and to manufacture a mold which generates less amount of gum causing defects during casting.
