PURPOSE: To make an electromagnet device which has the little reductions of attraction and sensitivity by mutually abutting the coil wound region of one yoke piece to the wide iron attraction region of the other yoke piece. CONSTITUTION: A yoke piece 2 and a yoke piece 5 are combined. That is, the yoke piece 2 has a wide iron attraction region 4 extended from one end of a coil wound region 3 and the iron attraction region 4 is bent in nearly a U-shape. Meanwhile, the yoke piece 5 has a wide iron attraction region 7 of nearly an L-shape extended from one end of a coil wound region 6 and the iron attraction region 7 is bent nearly at a right angle. A yoke 1 is made by positioning the coil wound region 3 of the yoke piece 2 in the direction of the thickness of a plate along the coil wound region 6 of the yoke piece 5, by abutting the end surface of the coil wound region 3 to the inside surface of the iron attraction region 7 and by abutting the end inside surface of the coil wound region 6 to the outside surface of the iron attraction region 4.

82 Magnetic circuit and variable inductance element JP10652185 1985-05-17 JPS61264704A 1986-11-22 IWAI MASARU
PURPOSE:To utilize a magnetic circuit for a temperature monitor by providing an electric circuit as a variable inductance element by utilizing the magnetic circuit for varying a magnetic resistance by moving a magnetic unit by the deformation of an SMA with the element for varying the coupling degree of a coil with a core by the deformation of an SMA wire. CONSTITUTION:When an SMA5 is formed at an ambient temperature in the shape as shown in Fig. (a) and when the SMA5 is deformed at 40 deg.C or higher as shown in Fig. (b) due to the opening of the opposed parts of the both ends of a core 3, the magnetic resistance of the core 3 largely reduces in case of Fig. (a) as compared with the case of Fig. (b). Accordingly, a magnetic circuit which can vary its magnetic resistance by the temperature can be provided. When the magnetic circuit has the primary and secondary winding 1, 2, the electromagnetic coupling degree of the windings can be largely varied to be provided as a variable mutual inductance element. The inductance of the coil may be altered by changing the relative position of the magnetic unit and the coil without varying the magnetic resistance. An SMA wire is used as a coil, and a variable inductance element which alters the magnetic resistance of the magnetic circuit by the deformation may be provided.
83 Reactor for semiconductor circuit JP1933784 1984-02-07 JPS60164312A 1985-08-27 SAWA TAKAO; KAWAKITA KATSUHIKO; HIROSE YORIO
PURPOSE:To prevent current spike and current ringing which are principal causes of noise without substantially reducing the efficiency eta, by forming a core with a thin plate of an amorphous magnetic alloy having a specific surface roughness. CONSTITUTION:A thin plate is constructed by combining a core formed of an amorphous magnetic alloy and a conductor, the amorphous magnetic alloy having a surface roughness as represented by the formula I . When the value of (t-t')/t exceeds 0.30, the roughness on the surface of the thin plate becomes remarkable and such a thin plate is not suitable for use since iron loss becomes extremely large in a high-frequency range. Further, if the surface roughness is large, the packing factor of the core becomes smaller and consequently the total magnetic flux becomes smaller. A toroidal core is formed by winding a ribbon which is made of amorphous magnetic alloy by single roll method, or is formed by laminating rings prepared by blanking the alloy. A reactor for semiconductor circuits can be obtained by providing this core with a plurality of windings.

The electromagnet can be used for actuation of valves, couplings or other electromechanical adjusting elements.
90 Magnetic core element, magnetic core module and an inductive component using the magnetic core module US14531006 2014-11-03 US09852838B2 2017-12-26 Johann Winkler
A rod-shaped magnetic core element, having a first end with a spherical or cylindrical recess or a spherical or cylindrical connecting protrusion, and a second end with a spherical or cylindrical recess or a spherical or cylindrical connecting protrusion so that a bent connection of at least two magnetic core elements is variably adjustable. Magnetic core elements comprising spherical or cylindrical magnetic core ends of this type allow a nearly gap-free construction with little magnetic leakage due to slightly larger end surfaces in comparison with ferrite rods having beveled plane end section surfaces. The enlarged end surface of the spherical surface advantageously allows a more stable connection of individual magnetic core elements without adhesive bonding. This allows the construction of flexible, multiple-member and inexpensive rod core coils and antennae.
