  • Publication number: 20190276612
    Abstract: A method for producing aluminum oxide is provided. The method uses an aluminum-oxide-forming agent containing a partially hydrolyzed aluminum alkyl compound containing an aluminum trialkyl or a mixture thereof, and a solvent. It is thus possible to produce an aluminum oxide thin film or aluminum oxide particles on or in a substrate that is not resistant to polar solvents. A method of producing a polyolefin-based polymer nanocomposite containing zinc oxide particles or aluminum oxide particles using a solution containing a partially hydrolyzed zinc alkyl or a solution containing a partially hydrolyzed aluminum alkyl is also provided. The polyolefin-based polymer nanocomposite contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, and does not contain a dispersant. The zinc oxide particles or aluminum oxide particles have an average particle size of less than 100 nm.

  • Patent number: 10367429
    Abstract: An object of this invention is to create an actuator in which the amount of deformation is maintained and no displacement in the reverse direction occurs, even when a constant voltage is continuously applied for a long period of time. As a means for achieving the above object, the invention provides a conductive thin film comprising a polymer gel containing at least one organic molecule selected from the group consisting of electron-donating organic molecules and electron-withdrawing organic molecules, a nano-carbon material, an ionic liquid, and a polymer.

  • Publication number: 20080177965
    Abstract: A backup data validity deciding flag 11 showing whether backup data is in a state of validity or invalidity is used to shelter data stored in a backup source storing medium 20 to a backup destination storing medium 21 and the flag 11 is changed to a validity. Further, when the data stored in the backup destination storing medium 21 is returned to the backup source storing medium 20, the flag 11 is changed to an invalidity. When the flag 11 shows the invalidity, the data is not returned. That is, when the backup data is returned once, the data cannot be returned again until a next sheltering process of the data arises.
