Patent number: 7782049Abstract: A magnetic device comprises a magnetic element, a first magnetic field application device, and a second magnetic field application device. The first and second magnetic field applying means are disposed on mutually opposite sides of the magnetic element. The magnetic element is, for example, an element in which a soft magnetic film is formed in a meandering shape on a nonmagnetic substrate. The first and second magnetic field application device create a magnetic field in one direction from the first magnetic field application device toward the second magnetic field application device. The bias magnetic field in one direction is thereby applied to the entire soft magnetic film in the magnetic element disposed between the first and second magnetic field application device.Type: GrantFiled: November 7, 2008Date of Patent: August 24, 2010Assignee: Fujikura Ltd.Inventors: Kazuhisa Itoi, Katsubumi Nagasu, Takuya Aizawa, Osamu Nakao, Shigekazu Kawai

Patent number: 7628938Abstract: The present invention provides a photochromic compound that is colored when irradiated with visible light and quickly faded when set in a dark place. The photochromic compound according to the present invention is expressed by the following general formula (I): where each of A1, A2 and A3 is a five-member rings forming a 6?-electron system, the three rings being identical, partially identical or totally different from each other, and each ring may have a substituent; B1 and B2 are functional groups, each having an atomic number of five or larger, including a ring compound, and bonded to the 2-carbon of each of A2 and A3, respectively; and R1, R2 and R3 are substituents identical to or different from each other. This compound is highly colorable and durable even when it is dispersed into plastic macromolecular materials. Therefore, it is suitable as a dye material for sunglasses or similar products.Type: GrantFiled: March 21, 2007Date of Patent: December 8, 2009Assignee: National University Corporation Nara Institute of Science and TechnologyInventors: Tsuyoshi Kawai, Takuya Nakajima, Shigekazu Kawai

Patent number: 6903702Abstract: An antenna is provided as a substrate member, and, as with the antenna, a ground part is provided as a substrate member. The ground part includes a folded pattern formed of a copper foil provided on the surface of a substrate material. When a folded pattern in the antenna and the folded pattern in the ground part are configured in a length of ?/4, a pseudo-antenna having a length of ?/2 can be formed. In this case, the antenna gain is about 2 dB, that is, the radiation of the radio wave can be improved. At the same time, the antinoise properties and the arrival distance of the radio wave can be improved. That is, the above construction can realize radio equipment which can stably radiate radio waves even under ungroundable conditions and, at the same time, can realize good characteristics even under low transmission output conditions.Type: GrantFiled: January 28, 2003Date of Patent: June 7, 2005Assignee: Sanyo Electric Co., Ltd.Inventors: Shigekazu Kawai, Tsutomu Ishikura, Yutaka Saito, Tsutomu Tanaka, Kazuo Matsubara
