Abstract: A multilayer ceramic condenser comprises a multilayer body constituted by a plurality of dielectric layers laminated together, first and second terminal electrodes respectively positioned on opposite side faces of the multilayer body, and a plurality of inner electrode groups provided within the multilayer body in a laminating direction of the multilayer body. Each inner electrode group includes a first inner electrode connected to the first terminal electrode, a second inner electrode connected to the second terminal electrode, and a third inner electrode connected to none of the first and second terminal electrodes. The first, second, and third inner electrodes are arranged so as to hold the dielectric layer therebetween such that a plurality of capacitors connected in series are formed between the first and second inner electrodes.

Abstract: The permanent magnetic alloy of the present invention comprises an R—Fe—B alloy wherein R is at least one element selected from rare earth elements including Y. The R—Fe—B alloy has a composition mainly comprising Fe, substantially containing no N, and containing 4 at. % or more of B. The permanent magnetic alloy substantially comprises a TbCu7 hard magnetic phase (main phase) and a fine crystal having an average crystal grain size of less than 5 nm and/or an amorphous phase, and has high magnetic properties.

Abstract: There is disclosed a rare earth permanent magnet composed of a sintered product consisting of R and M where R represents at least one rare earth, and M represents Co or a combination of Co and at least one kind selected from the group consisting of Fe, Ni and Cu, the sintered product being of such a composition that a RM.sub.5 phase and a R.sub.2 M.sub.7 phase occur in the sintered product. The sintered product contains 63 to 65 wt. % of M, and the sintered product has a coercive force iHc of not less than 13,000 Oe. The permanent magnet can have a disk-shape, a ring-shape or a cylindrical shape. A method of heat treatment of the permanent magnet is also disclosed.
