    摘要： A FePt alloy nanoparticle, which is expected to be a promising material used for an ultra-high-density magnetic recording medium of the next generation, is ordered by heat treatment to have high magnetic anisotropy, but there has been a problem that the particles are coalesced with each other and agglomerate during the heat treatment. According to the present invention, each particle of the alloy nanoparticles is covered with a coating such as SiO2, and thereafter a heat treatment for ordering is carried out. In this method, the alloy nanoparticles do not coalesce with each other even if the heat treatment is performed at such a high temperature as to allow all the particles to be fully ordered. After the heat treatment, only the coating is removed using an acid or alkali solution so that it is possible to obtain ordered alloy phase nanoparticles which are ordered and dispersible in various solutions. It is also possible to easily manufacture an ultra-high-density magnetic recording medium by coating surfaces of a substrate with a binder solution in which the particles are dispersed while applying a magnetic field in a predetermined direction.

    摘要： A CM type directional coupler comprises a body having a dielectric layer, an annular magnet buried in the dielectric layer, a pair of transmission lines juxtaposed with a predetermined spacing between them in a magnetic area enclosed by the magnetic ring in the dielectric layer, and lead terminals extending from opposite ends of each of the transmission lines to outside of the dielectric layer, and all these elements are formed integrally with each other to provide a single device. Therefore, a large coupling factor and directivity are ensured, and the coupler can be designed very compact. This directional coupler can be manufactured with a highly improved yield and mass-producibility, so it is very suitably usable as a power detector in a portable telephone.

    摘要： To provide a voltage controlled oscillator having small size and capable of obtaining a low phase noise characteristic over a large span of adjustable range of frequency. A quartz crystal having a characteristic (dielectric loss tangent: tan δ) better than that of fluorocarbon resin, LTCC or the like conventionally used as a substrate of a resonance part 1, and on which a fine pattern of metal film can be formed through a photolithography method, is used as a quartz-crystal substrate 10, and a conductive line is formed on the quartz-crystal substrate 10 to form an inductance element 11 in the resonance part 1. Accordingly, since the resonance part 1 having a high Q value can be formed, it is possible to obtain a voltage controlled oscillator having small size and low loss over a wide frequency band.
