  • Patent number: 7952915
    Abstract: A novel element capable of simply controlling an in-plane rotational motion of a core (a rising spot of a magnetization) generated in the center of a ferromagnetic dot made by forming a ferromagnetic material into a nanosized disk shape is provided. In addition, a binary information memory element using a core, including a ferromagnetic dot, made of a disk-shaped ferromagnetic material, with a magnetic structure of a magnetic vortex structure, and a current supplier for supplying an alternating current with a predetermined alternating current in the radial direction of the ferromagnetic dot is provided. In the case where the frequency of the current resonates with the intrinsic frequency of the ferromagnetic dot, it is possible to rotate the core in the plane of the dot. Since the core leaks a magnetic field, a microscopic actuator such as a motor can be obtained by using this element. Furthermore, supplying a current having a density not less than a predetermined value reverses the core.

  • Publication number: 20100230287
    Abstract: Gold is subjected to anodic oxidation in an aqueous solution of a carboxylic acid or carboxylate. The carboxylic acid can be selected from formic acid, acetic acid, propionic acid, lactic acid, oxalic acid, malonic acid, succinic acid, maleic acid, malic acid, tartaric acid, and citric acid. The carboxylate can be selected from salts of the above-described acids. A potential applied to a gold electrode can be in the range of about +1.5 to about 11 V with respect to a potential of a standard hydrogen electrode. Thereby, a uniform porous gold film having a pore size of several nanometers to several hundreds of nanometers is formed.

  • Publication number: 20100207050
    Abstract: The formation of cracks is suppressed in a drying process for a water-containing wet gel without modifying the gel and without using a reagent. A water-containing wet gel is dried by removing water and then removing the remaining solvent. For example, a wet-gel container storing water-containing wet gel, containing a wet gel and a solvent, is heated. The solvent is vaporized into an upper space of the wet-gel container. The solvent-containing gas diffuses into a dehydrating agent container, and water is removed by a dehydrating agent. This state is maintained for one to two days to remove almost all amount of water from the solvent. Thereafter, the dehydrating agent container is detached and the wet gel, from which water has been removed, is heated to almost completely remove the solvent, and further heated at a higher temperature to completely remove the solvent to obtain a crack-free dry gel.

  • Publication number: 20100020966
    Abstract: The present invention relates to an encryption key generating method ensuring resistance to collusion attacks and achieving reduction in a key length of encryption keys corresponding to respective hierarchies of each scalability. In the encryption key generating method, an encryption key (K2,2) corresponding to data in the lowest hierarchies of hierarchical scalabilities (R, L) is divided as a master key by the number of hierarchies in scalability (R). Key element matrices (M1-M3) generated with respective split keys (eR2, eR1, eR3) are assigned operation data successively obtained by repeating a hash operation with a one-way hash function, so as to maintain hierarchical nature of scalability (L). Partial keys (K1,1-K2,2) corresponding to respective hierarchies of the scalabilities (R, L) are generated by combining key elements coordinately consistent among the key element matrices (M1-M3).

  • Publication number: 20090226790
    Abstract: A first fine particle-containing solution is deposited on an appropriate substrate, and dried to form a first fine particle aggregate layer. Polymer particles are deposited on the first fine particle aggregate layer, and are supplied with a second fine particle-containing solution such that the polymer particles are immersed in the second fine particle-containing solution. The second fine particle-containing solution is dried to form a second fine particle aggregate layer containing a large number of the polymer particles embedded. A first structure precursor is completed at this stage. Then, the first structure precursor is separated from the substrate, and thermally treated. Thus, the production of a first solid electrolyte structure, which has a porous solid electrolyte portion and a dense solid electrolyte portion integrated, is completed.
