Patent number: 7952915Abstract: 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.Type: GrantFiled: March 1, 2007Date of Patent: May 31, 2011Assignees: Kyoto University, The University of Electro-Communications, Osaka University, Tokyo Metropolitan UniversityInventors: Teruo Ono, Shinya Kasai, Kensuke Kobayashi, Yoshinobu Nakatani, Hiroshi Kohno, Gen Tatara

Publication number: 20100207050Abstract: 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.Type: ApplicationFiled: February 18, 2010Publication date: August 19, 2010Applicant: TOKYO METROPOLITAN UNIVERSITYInventors: Koichi Kajiwara, Ryohei Maehana, Shungo Kuwatani, Kiyoshi Kanamura

Publication number: 20100020966Abstract: 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).Type: ApplicationFiled: November 4, 2008Publication date: January 28, 2010Applicants: SUMITOMO ELECTRIC INDUSTRIES, LTD., TOKYO METROPOLITAN UNIVERSITYInventors: Yoichi Hata, Toshiaki Kakii, Yasuhito Fujita, Yoshimitsu Goto, Hitoshi Kiya, Kiyoshi Nishikawa, Masaaki Fujiyoshi, Shoko Imaizumi
