摘要： PURPOSE: To provide a common-mode choke coil which has a sufficient noise- filter effect with reference to a normal-mode noise in addition to a common- mode noise and which is small. CONSTITUTION: Coils 5, 6 are wound in common on a first torus-shaped core 1 and on a second core 2 which is arranged at the inside of the first core 1. A spacer 3 is sandwiched between the first core 1 and the second core 2. The second core 2 is constituted of a torus-shaped frame part 2a and of a bridge part 2b which is bridged on the frame part 2a. As a material for the first core 1, a material which may be magnetically saturated easily but whose permeability is large, i.e., a material whose specific permeability is several thousand, is preferable, and a ferrite, an amorphous material or the like is used. As a material for the second core 2, a material which is hard to magnetically saturate, i.e., a material whose specific permeability is several tens to several hundred, is preferable, and e.g. a dust core or the like is used.

摘要： PURPOSE:To provide a noise filter excellent in attenuation characteristic by using a magnetic material having a high saturation flux density together with a high magnetic permeability as a magnetic core. CONSTITUTION:In the noise filter in which the torus-like magnetic core 10 formed by winding toroidally the alloy thin belt 12 consisting of the magnetic material is housed in a case 14 consisting of a dielectric material to which a coil 16 is wound and the case is disposed in an electronic circuit, the magnetic material is a soft magnetic alloy consisting of the composition shown in the formula FebBxMy. M is at least one or >=2 kind elements selected from among Ti, Zr, Hf, V, Nb, Ta, Mo and W, and contains either Zr or Hf or both Zr and Hf, (b) is 75

摘要： PURPOSE: To provide an induction device whose manufacture is easy and which can be transferred as a single body. CONSTITUTION: The induction device is provided with a first winding constituted of conductive segments formed as an almost U-shaped plate having two parallel end parts which are provided on a core (1) and whose widths differ and a wedge-like center part. The segments are formed as parts obtained by making the outer face of a cap (19) whose section is formed as the U-shape ring and which is generated by an electrically insulating material into a metal. The segments are mutually and electrically detached by a non-metallic fine wire part (25) in the outer face of the cap (19). The cap (19) is provided with a metallic pin (21) which constitutes a connection member for segment and which is connected to the conductor (39) in a printed circuit board (41). The segments constitute the first winding together with the conductor (39).

摘要： PURPOSE: To miniaturize a device by providing a primary winding formed of a pair of metal-made wall parts and a plurality of secondary winding assemblies in a space between a pair of wall parts so that the respective assemblies provide an output from the device as a whole. CONSTITUTION: A primary winding 30 is provided with a first metal-made cylindrical wall part 111 having a longitudinal axial line and a second metal-made wall part 107 surrounding the first wall part 111, and the primary winding 30 for generating one by one a part of high-voltage DC led from an electric power supplying device is magnetically connected to a plurality of secondary winding assemblies. The assemblies include respective magnetic cores 41 to 46, windings 31 to 36 wound on the respective cores 41 to 46 and rectification means 51 to 56 connected to the respective windings 31 to 36. A means for adding a voltage generated inside the volume of the secondary winding assemblies is provided, and further, a capacitor 25 having the value of nearly resonating a transformer to an AC power source is connected in series to the primary winding 30.
