  • Publication number: 20210295914
    Abstract: A selector malfunction caused by a drift is prevented in a memory having a cross-point structure. A memory cell array is provided with a data area and a drift reference cell. An accumulated drift amount acquisition unit acquires an accumulated drift amount of the drift reference cell. A total drift amount reading unit reads a total drift amount stored in the data area. A refresh control unit adds the accumulated drift amount to the total drift amount to update the total drift amount as a new total drift amount. Further, the refresh control unit refreshes the data area of the memory cell array in a case where the new total drift amount exceeds a predetermined threshold value.

  • Patent number: 11092308
    Abstract: A light emitting element, a reflector, a projection lens, and a movable shade are arranged in a lamp chamber. As the movable shade is erected, a low beam is formed. As the movable shade is tilted, a travelling beam is formed. The reflector and a sub reflector are integrally formed. The movable reflector reflects the reflected light reflected by the sub reflector toward the projection lens. The sub reflector is positioned in a range of an outer shape of the projection lens.

  • Patent number: 10551022
    Abstract: A vehicle lamp includes a light source, a rotation reflector that includes a reflective surface that reflects emission light emitted from the light source while rotating, a projection lens that projects the reflected light from the rotation reflector to a front of the vehicle, and a movable shade provided between the rotation reflector and the projection lens. The movable shade is configured to be movable between a first position where the reflected light passes when the reflected light is projected to the front side of the vehicle and a second position where at least a part of incident light that is incident from the projection lens is shielded so as not to reach the rotation reflector.

  • Patent number: 8207085
    Abstract: A photocatalytic coating composition comprising photocatalytic titanium oxide, silver, copper and a quaternary ammonium hydroxide. The photocatalytic coating composition may include a photocatalytic titanium oxide sol dispersed in a binder. Furthermore, a photocatalytic member includes a substrate having a surface coated with the photocatalytic coating composition. The photocatalyst coating composition can contain highly antibacterial silver by skillfully utilizing copper and a quaternary ammonium hydroxide, and accordingly can show an antibacterial effect not only in a dark place simply due to silver, but also a higher antibacterial effect in a conventional application of employing ultraviolet sterilization by concomitantly using the photocatalyst titanium oxide sol according to the present invention and an ultraviolet sterilizer.
