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 communication control apparatus that enables a personal computer usually connected to a LAN when in use to be connected temporarily to the same LAN from a different location and via a different communication device, while ensuring security without time and effort spent on configuration. A communication control apparatus connected to a LAN including a server, personal computers and communication devices (e.g., routers) that relay data between the server and the personal computers is provided with: a storage device that stores a scheduled time at which a personal computer is connected for use at another location in the same LAN, information of a communication device for the other location and configuration information of the communication device for enabling communication with the personal computer; and a timer indicating a time. The communication control apparatus compares the scheduled time and the time indicated by the timer, and performs configuration of the communication device to which the personal computer is scheduled to be connected based on the information of the communication device and the configuration information that are stored in the storage device, before the scheduled time.
