摘要： PROBLEM TO BE SOLVED: To provide powder for dust cores for securing the insulating properties of piezomagnetic powder and suppressing a reduction in the magnetic flux density of molded dust cores.
SOLUTION: Magnetic powder contains powders for dust cores 10A and 10B with an insulating layer formed on the surface 11a of magnetic powder 11. As the powder for dust cores, there are at least contained: a first powder for dust cores 10A having at least a first insulating layer 12a and a second insulating layer 12b successively formed as an insulating layer from the surface 11a of the magnetic powder 11 in the layer thickness direction of the insulating layer 12A, with the hardness of the second insulating layer 12b higher than the hardness of the first insulating layer 12a; and a second powder for dust cores 10B, with a soft insulating layer 12b having the hardness lower than the hardness of the second insulating layer 12a of the first powder for dust cores 10A formed as an insulating layer.

摘要： PROBLEM TO BE SOLVED: To provide a battery holder 10 which extends overall lives of multiple batteries and prevents the batteries from rising their temperatures in a chain reaction when some of the batteries cause temperature rise larger than other batteries.SOLUTION: A battery holder 10 includes: a support medium 20 having battery holding holes 21S; and holder parts 30, each of which is disposed between the battery holding hole 21S and a battery Bt. The holder part 30 includes a first spacer 32 and a second spacer 34. The first spacer 32 includes a support part 32b supporting the battery Bt on the support medium 20. The second spacer 34 is formed by a material having a melting point lower than a melting point of a material of the first spacer 32, is inserted into a heat blocking space 30S, and is formed so as to use the heat blocking space 30S as an air layer when the second spacer 34 is melted by heat and flows out from the heat blocking space 30S.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive dust core that is excellent in electric characteristics and magnetic characteristics. SOLUTION: This dust core is manufactured by press-molding iron-based magnetic powder having an oxide coating film on its surface. The saturation magnetization Ms and specific resistance ρ of the dust core in a magnetic field of 1.6 MA/m are respectively adjusted to Ms>=1.9 T and ρ>=0.7 μΩm and the magnetic flux density B2k of the core in a magnetic field of 2 kA/m is adjusted to B2k>=0.9 T. In addition, the magnetic flux density B10k and four-point bending strength σ of the core in a magnetic field of 10 kA/m are respectively adjusted to B10k>=1.6 T and σ>=50 MPa. Since the oxide coating film is formed on the surface of the magnetic powder, the electric characteristics and magnetic characteristics of the dust core are improved and the manufacturing cost of the core is reduced.
