摘要： PROBLEM TO BE SOLVED: To provide a dust core excellent in specific resistance and strength.SOLUTION: The dust core includes soft magnetic particles, and a grain boundary phase formed among the soft magnetic particles. The grain boundary phase has a such composite dispersion system in which fine particles containing a high temperature softening material (nano particles of silica and aluminum) which contain a second inorganic oxide having a softening point higher than an annealing temperature are dispersed in the matrix containing a low temperature softening material (low-melting point glass particles) that contains a first inorganic oxide having a softening point lower than the annealing temperature of the soft magnetic particle. Since the grain boundary phase has the composite dispersion system like this, the soft magnetic particles are strongly coupled by the low temperature softening material and a predetermined interval is held by the high temperature softening material, to assure insulation property. Thus the dust core in which both a high specific resistance and a high strength are provided in a high dimension is provided.

摘要： PROBLEM TO BE SOLVED: To provide a new paint composition that hardly degrades in spite of containing an organic titanosilicate and is capable of forming a paint film excellent in weatherability. SOLUTION: The paint composition is characterized by being formed by dissolving in a solvent the organic titanosilicate which is composed of an oxide of silicon and a metal containing a bond represented by M-O-M (M's indicate each independently a silicon atom or a metal atom) and contains an organic group bonding with at least part of the silicon atoms and of which at least part of the metal atoms are a titanium atom. The paint composition is further characterized by containing a stabilizer having radical-trapping ability and/or anti-oxidation ability. The paint film is prevented from degrading by adding the stabilizer that inhibits formation of an oxidative atmosphere caused by transition of the titanium atom and traps a radical. Adding the stabilizer not only prevents the paint film from degrading, but also improves weatherability of the paint film. COPYRIGHT: (C)2010,JPO&INPIT
