Abstract: PURPOSE:To provide the composite magnetic head which prevents the generation of a pseudo gap and maintains high reproduced output and the production process thereof by forming nitrided layers of ferrite between ferrite core half bodies and magnetic metallic films and forming the magnetic metallic films in an atmosphere added with gaseous oxygen. CONSTITUTION:The nitrided layers 6, 6a of the ferrite formed by the heat- treatment in a gaseous nitrogen atmosphere are provided between the ferrite core half bodies 3, 3a and the magnetic metallic films 4, 4a of the composite magnetic head 1 joined with composite core half bodies 2, 2a consisting of the ferrite core half bodies 3, 3a and the magnetic metallic films 4, 4a having the saturation magnetic flux density higher than the saturation magnetic flux density of the ferrite via a gap. The magnetic metallic films 4, 4a are formed by sputtering in the atmosphere of the gas formed by adding gaseous oxygen to an inert gas. The generation of the pseudo gap is then prevented and the film quality and magnetic characteristics of the magnetic metallic films 4, 4a are stabilized. The characteristics of the composite magnetic head are thus effectively improved.

Abstract: PURPOSE:To prevent the decrease of electromagnetic waves sielding performance when a cable bundle inserted into a soft hood is distributed to two or more electronic apparatuses, in an electromagnetic waves shielding soft hood which is fixed to a cable insertion port of an electronic apparatus cabinet and shields the electromagnetic waves passing the port. CONSTITUTION:A conductive soft hood 10 is constituted as a trident cylinder, and notches 18 are formed in the apertures of cylinders 10a-10c. A cable bundle 26 inserted from a cable insertion port is divided to small cable bundles 26a-26c, and led out from the cylinders 10a-10c. The apertures of the cylinders 10a-10c are so closed that the cable bundles 26a-26c are applied to shafts, and the notches 18 are overlapped, squeezed and blocked. Thereby the squeezed apertures are not stretched and gaps are not generated, when the cable bundle 26 is divided to three directions and wired. Gaps are not generated also on the aperture periphery. As the result, the electromagnetic waves shielding performance is not deteriorated by distributing the cable bundle.

However, when the solder does not join the parts 1 properly, the faulty connected section is separated by the vacuum suction, and thus, the circuit loop is discontinued and the disconnected state becomes distinctive, resulting in high impedance in the circuit loop. Therefore, the unit 9 detects the high impedance and the faulty connection is detected.
