Abstract: A multilayer hybrid circuit, which looks like a conventional printed circuit board, has a laminated body having at least one of a plurality of dielectric layers, magnetic layers, and conductive patterns, composing a capacitor, an inductor, and a resistor, and mounts a semiconductor chip. An external connection is effected by side terminals positioned on side walls of the laminated body. In one embodiment, said laminated body and said semiconductor chip are molded together by plastics so that the result looks as if a conventional semiconductor chip. In another embodiment, a resilient relay board is coupled with the laminated body when mounted on a mother board so that stress on the mother board is not applied directly to the laminated body.

Abstract: A multilayer hybrid circuit having a laminated body having at least one of a plurality of dielectric layers, dielectric magnetic layers, and conductive patterns on said dielectric layers and said magnetic layers, is produced through a printing process and a sintering process, and comprises capacitors, inductors, and resistors. An external connection is effected by side terminals positioned on side walls of the laminated body. A coupling conductor which is perpendicular to a dielectric plane is provided for coupling elements on different planes. Said coupling conductor is a succession of essentially S-shaped conductor chips or lines with the ends connected to adjacent conductor chips on different planes. That coupling conductor functions via a through hole conductor in a prior printed circuit board, and has high operational reliability in a component which is produced through a sintering process.

Abstract: A composite electric part of a stacked multi-layer structure is composed of a capacor layer and a coil layer. The coil layer comprises a plurality of coils buried in a magnetic material. At least one of the coils includes a plurality of coil conductors which comprises combinations each of two coil conductors would spirally in opposite directions around respective winding axes extending substantially coaxially with each other, and mutually connected such that magnetic fields are generated in a same direction by the two coil conductors. A miniature size of composite electric part exhibiting a high inductance value is realized.

Abstract: Laminated components of the open magnetic circuit type including, or incorporating, inductors of the same type are manufactured by alternately superposing a plurality of green magnetic layers and a plurality of fragmentary, green conductor strips, each strip constituting about half a turn of coil in coil-forming conductor patterns, in such a manner that the ends of the conductor strips overlap the ends of adjacent strips whereas the remainders of the adjacent strips are separated by each interposing magnetic layer, the conductor strips being arranged so that they are vertically superposed along the same spiraling loci, sintering the resulting laminate to a solid sintered body, and, before or after the sintering, sectioning the laminate along the spiraling loci into individual components.

Abstract: A DC-DC converter of a laminated, hybrid integrated type comprising a laminated transformer having printed conductor layers on its surface and electronic components attached to the surface. The laminated transformer is formed by alternately laminating a plurality of insulator layers and two sets of conductor layers insulated from each other. The conductor layers are connected at ends to constitute primary and secondary wirings in an inter-layer formation. The laminated transformer has a glass undercoat formed thereon or a laminated capacitor deposited on its surface to provide a base for the other electronic components.

Abstract: A chip-shaped laminated electronic part including at least one inductor, which comprises a plurality of sheets of an insulating material, and electrically conductive patterns each formed on the surface of each said sheets, said patterns being so connected to form one or more coils to provide at least one inductor. The electronic part is monolythic and is produced by using printing technique whereby wire-winding operation is eliminated.
