摘要： A thick film complex electronic component mounted on a substrate including an inductance, capacitance and/or resistance by a conductive film and a magnetic film on a ceramic substrate is improved by novel magnetic film. The magnetic film is produced by depositing paste of a raw material of ferrite on the substrate, and the paste together with the substrate are sintered at a relatively low temperature in the range of 600.degree. C. and 1200.degree. C. The present magnetic film which is sintered after the raw material of ferrite is deposited on the ceramic substrate has higher permeability and is mechanically stronger.

摘要： A fixed attenuator for microwave band comprising of a dielectric substrate, with a resistance film and a conductor film attached on said substrate so as to form an attenuation circuit. The substrate further comprises of at least one hole provided through the dielectric substrate. The attenuator is mounted on a metallic board or a printed circuit board by a screw inserted in said hole. Thus, the cooling effect of the resistance film has been improved while keeping the low manufacturing cost and stable structure, by fixing the dielectric substrate on a metallic board by screws inserted in the mentioned holes.

摘要： A method for manufacturing a cylindrical armature having an armature winding arranged cylindrically and a cylindrical insulating layer formed at least on the outer peripheral surface of the cylindrical armature winding by winding an insulating material impregnated with thermosetting resin is disclosed. The insulating material is wound over the armature winding and on a jig adapted to be separated into an effective part corresponding to the cylindrical armature winding and a remaining ineffective part. After hardening the resin, the part of the insulating layer on the ineffective part is separated, together with the jig, from the effective part.
