    摘要： An atomized mixture of flat soft magnetic powder and an organic binding agent is rolled by mutually confronting two rolling rolls so as to easily produce a composite magnetic sheet excellent in electromagnetic wave absorption characteristic. A plurality of the composite magnetic sheets are stacked by forming unevenness on joining surfaces thereof and rolled so as to realize a desired thickness. By sandwiching a mesh metal layer between the foregoing two composite magnetic sheets and joining them by applying rolling thereto, a mechanically strong electromagnetic interference suppressing sheet can be easily obtained. For reducing reflection and transmittance of electromagnetic waves of the composite magnetic sheet, embossing is applied to obverse and reverse surfaces thereof.

    摘要： A mixture of flat soft magnetic powder and an organic binding agent is rolled by mutually confronting of rolls so as to produce a composite magnetic sheet excellent in electromagnetic wave absorption characteristic. A plurality of the composite magnetic sheets are stacked by forming groove surfaces on each of said plurality of sheets and rolled to a desired thickness. By sandwiching a conductive mesh metal layer between two of said composite magnetic sheets and joining them by applying rolling pressure thereto, a mechanically strong electromagnetic interference suppressing sheet can be easily obtained. In order to reduce reflection and transmittance of electromagnetic waves of the composite magnetic sheet, embossing is applied to obverse and reverse surfaces of the composite magnetic sheet.

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： A tube for externally covering or bundling electric cables is provided for suppressing radiation of undesired electromagnetic waves. The tube is made of a material in which soft magnetic powder is mixed with and dispersed into an organic binding agent. For protecting the cable from the undesired electromagnetic waves from the exterior, it is preferable to provide a conductor layer at an outer side of a composite magnetic layer. For facilitating mounting onto the cable, the tube is provided with a slit in a longitudinal direction. Alternatively, the cable may have a spiral structure. As an organic binding agent, it is preferable to use an elastomer which is excellent in extensible property. Further, it is preferable that the soft magnetic powder is powder being essentially flat.
