摘要： PROBLEM TO BE SOLVED: To radiate heat from a ferromagnetic core, by providing a layer made of an electrically and thermally conductive material on the core, and thermally coupling the core to a heat sink via this layer. SOLUTION: A dielectric device includes a core 2 made of a ferromagnetic material and a winding 1 wound on the core 2. To radiate heat, a layer 4 made of an electrically and thermally conductive material is provided on the ferrite core 2, and this layer 4 is coupled to a heat sink 3 in the form of cooling body. To prevent a current from being induced to the electrically and thermally conductive layer 4, a disconnecting section is provided in the layer 4. This electrically and thermally conductive layer 4 is formed on the ferrite core 2 by plating. In this case, a metal having an extremely high conductivity such as copper or silver in comparison with the ferrite material is used.

摘要： PROBLEM TO BE SOLVED: To mechanically firmly connect a support body to a unit by forming the support body into a shape matching the unit comprising a magnetic core and coil bobbin, and holding the unit by one or more spring clamp in the support body. SOLUTION: The support body has an L-shaped structure having two legs 20-1 and 20-2. The leg 20-1 has an empty space 21 for accommodating a coil bobbin 12. The unit comprising a magnetic core 10 and the coil bobbin 12 is placed in the empty space 21 on the leg 20-1, and attached to the leg 20-2 vertical to the leg 20-1. The unit is held by a spring clamp 23, surrounding the leg 20-1 and the magnetic core 10, in the support body 21 including the legs 20-1 and 20-2. Thus, the unit is mechanically firmly connected to the support body for a long period in a stable state. Further, the connection can be dissolved.

摘要： PURPOSE: To prevent formation of coarse grains even when a silicic acid rich iron oxide is used as a starting material by doping ferrite, e.g. zinc manganese ferrite, with a molybdenum compound. CONSTITUTION: When an iron oxide containing silicic acid is used as a starting material, ferrite is doped with a molybdenum compound. Molybdenum oxide is employed as the molybdenum compound. Ferrite is doped with 0.01-0.03 wt.% of molybdenum oxide. This composition produces a ferrite having high saturation induction and low loss even when a silicic acid rich starting substance is employed.

摘要： PROBLEM TO BE SOLVED: To elimibate the need for the use of a bonding agent and the guarantee a high degree of dimensional accuracy by a method, wherein a coil former is welded to a core using a plastic surplus part in an inductance element wherein a core, consisting of ferromagnetic material and the coil former to be used to wind a winding, are formed into a unit. SOLUTION: A core 1, provided with a coil former 7, is passed through the flange 4 on the supporting substrate 2 and the through-hole 3 of the core, or passing thorough a core window, or depending on circumstances, the core 1 is set in such a manner that it protrudes from the through-hole 3, provided with a nose-shaped protrusion 5 and facing opposite to the supporting substrate 2, or protruding from the end face of the core window. Then, the protruding end of the flange 4 is heated by a heating rod, for example, the thermoplastic plastic is softened or fused. Accordingly, the protruding end of the flange 4 is expanded in the through-hole 3 or on the end face of the core window, and a fixing head part 6 is formed. In addition, the core 1 is positively fixed to the supporting substrate 2 by softening the plastic, and an inductance element is formed.

摘要： PROBLEM TO BE SOLVED: To prevent the piling of remained slag of an enamel onto a contacting pin and to improve a brazing-joinability of the pin at the time of assembling onto a printed circuit by overflowing molten brazing filler metal in a hrazing bath tub before drawing up the contacting pin after completing the hrazing to clean the bath surface, at the time of automatically clip-brazing the copper enamel wire wound on the contacting pin of an electric device. SOLUTION: A brazing apparatus has a structure arranging the brazing bath tub 5 for dipping the contacting pins of the electric device 6 having the copper enamel coils 8 at the upper part of a fixed type heating brazing bath vessel 1, providing a dipping body 9 moving in the vertical direction and connecting a brazing storing vessel 3 which is communicated with the heating brazing bath vessel 1, with pipes 4. At the time of brazing, the contacting pins 7 are dipped into the brazing bath tub 5, and after brazing the coils 8, a dipping body 9 is worked and the brazing filler metal 2 in the hrazing storing vessel 3 is fed into the brazing bath tub 5 through the pipes 4. The molten brazing filler metal in the brazing bath tub 5 is overflowed, and after removing the remained slag of the enamel from the bath surface, the contacting pins 7 are drawn up.
