    摘要: An EMI countermeasure component is provided relative to an active element, which does not deteriorate a circuit function of the active element, but has a sufficient shielding effect against permeation of electromagnetic waves radiated to the exterior, and further suppresses a malfunction or the like due to mutual interferences between peripheral components or an electromagnetic induction to a signal line. The EMI countermeasure component is made of a composite magnetic body including soft magnetic powder having oxide films on the surfaces thereof and an organic binding agent, and extinguishes undesired high frequency electromagnetic radiation as heat due to its complex permeability.

    摘要: A thin electromagnetic interference suppressing body effective for electromagnetic interference suppression at a microwave band. As a material of the electromagnetic interference suppressing body, there is provided a composite magnetic body formed by bonding powder made of a semi-hard magnetic material by an organic bonding agent and having a high magnetic loss at the microwave band. As the semi-hard magnetic material, a metallic magnetic body, such as Fe--Co--Mo alloy, Co--Fe--Nb alloy or Fe--Co--V alloy, or an oxide magnetic body, such as .gamma.-Fe.sub.2 O.sub.3 or Co--Ti substituted Ba ferrite, can be used. Further, as an example of the organic bonding agent, polyurethane resin can be cited.

    摘要: A dual-band nonreversible circuit device comprises a first circulator element (91) and a second circulator element (92) accommodated in a single housing (50, 50', 60) and operable around a first center frequency (f.sub.A) and a second center frequency (f.sub.B), respectively. The first circulator element (91) is formed by a combination of a first permanent magnet (31), a first ferrite plate (21) with a first center conductor (11), and a ground conductor plate (40) successively stacked on a lower magnetic yoke (50). Likewise, the second circulator element (92) is formed by a combination of the ground conductor plate (40), a second ferrite plate (22) with a second center conductor (12), and a second permanent magnet (32) successively stacked and covered by an upper magnetic yoke (60). Alternatively, a first circulator element (91') is formed by a combination of a first ground conductor plate (41), the first ferrite plate (21) with the first center conductor (11), and a permanent magnet (30) while the second circulator element (92') is formed by a combination of a second ground conductor plate (42), the second ferrite plate (22) with the second center conductor (12), and the permanent magnet (30).

    摘要: In an optical fiber cable, for effectively suppressing undesired radiant noise propagating in a reinforcing wire or generated from the reinforcing wire without providing an electromagnetic shielding member apart from the optical fiber cable, a buffer layer and an outer jacket of an LAP sheath covering the reinforcing wire being a tension member forming the optical fiber cable are constituted by composite magnetic bodies, respectively, composed of soft magnetic powder and organic binding agents. It is preferable that the soft magnetic powder is powder being essentially flat.
