  • Publication number: 20210323283
    Abstract: The purpose of the present invention is to provide a sheet body having an improved function of preventing icing and/or snow accretion. At least included are a solid oil-containing resin layer containing an oil and an oil-permeable surface resin layer that has higher wear resistance than the oil-containing resin layer and is layered on one of surfaces of the oil-containing resin layer. The oil included in the oil-containing resin layer includes a low-temperature exuding oil component capable of exuding from the oil-containing resin layer when a temperature decreases to a predetermined value or lower, and the surface resin layer has enough oil permeability to permeate the low-temperature exuding oil component exuding from the oil-containing resin layer to a surface of the surface resin layer that is opposite to a side of the oil-containing resin layer.

  • 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.
