摘要： A method for producing a rare earth magnet material which allows efficient Dy or the like diffusion into an inside thereof. This method includes a preparation step of preparing a powder mixture of magnet powder including one or more rare earth elements including neodymium, boron, and the remainder being iron; and neodymium fluoride powder; a heating step of heating a compact of the powder mixture and causing oxygen around magnet powder particles to react with the fluoride powder, thereby obtaining a lump rare earth magnet material in which neodymium oxyfluoride is wholly distributed. The fluoride powder traps oxygen enclosed in the powder mixture and fixes the oxygen as stable NdOF. When Dy is diffused into this rare earth magnet material, Dy smoothly enters into its inside without being oxidized at grain boundaries. Consequently, coercivity of the entire rare earth magnet material can be efficiently increased without wasting scarce Dy.

摘要： A replication system rapidly switches from a normal-system site to a standby-system site in the event of a problem and reliably maintains functions, and moreover, reduces drops in performance. A first site provides system functions that accompany writing and reading of data. A relay transfer device receives update information from the first site, causes completion of processes for replication in the first site, and continuously executes processes for successively transferring the update information to a second site. The second site receives the update information of the first site and applies this update information to itself to retain a replica of the data of the first site. If, when executing a write request command or a read request command to provide at least a portion of the system functions, the second site has not yet retained the most recent data that are the target of the command, the second site acquires the necessary update information and then executes the command.

摘要： Magnetic alloy powder for a permanent magnet contains: R of about 20 mass percent to about 40 mass percent (R is Y, or at least one type of rare earth element); T of about 60 mass percent to about 79 mass percent (T is a transition metal including Fe as a primary component); and Q of about 0.5 mass percent to about 2.0 mass percent (Q is an element including B (boron) and C (carbon)). The magnetic alloy powder is formed by an atomize method, and the shape of particles of the powder is substantially spherical. The magnetic alloy powder includes a compound phase having Nd2Fe14B tetragonal structure as a primary composition phase. A ratio of a content of C to a total content of B and C is about 0.05 to about 0.90.
