An R-T-B based sintered magnet maintains high magnetic properties and decreases usage of heavy rare earth elements. The magnet includes main phase grains and grain boundary phases, the main phase grain containing a core portion and a shell portion. X in the main phase LR(2-x)HRxT14B of the core portion ranges from 0.00 to 0.07; x in the main phase LR(2-x)HRxT14B of the shell portion ranges from 0.02 to 0.40; and the maximum thickness of the shell portion ranges from 7 nm to 100 nm. LR contains Nd and one or more light rare earth elements consisting of Y, La, Ce, Pr and Sm; HR contains Dy or/and Tb and one or more heavy rare earth elements consisting of Gd, Ho, Er, Tm, Yb and Lu; T contains Fe or/and Co and one or two kinds of Mn and Ni; and B represents boron partly replaced by C (carbon).

R-T-B based sintered magnet

The present invention provides a rare earth based sintered magnet. The magnet is a rare earth based permanent magnet with a R-T-B (R represents one or more elements selected from Y and rare earth elements, T represents one or more metal elements including Fe or the combination of Fe and Co, and B represents B or the combination of B and C) based composition. When a R-rich phase (R represents rare earth element(s)) with atomic ratio of (Fe+Co)/(LR+HR+Fe+Co)&#x2266;0.2 (LR represents Y and light rare earth element(s) selected fromLa toEu, and HR represents heavy rare earth element(s) selected fromGd toLu) is present in the grain boundary triple point, a region with HR/(LR+HR)&#x2267;0.01 (atomic ratio) is present in the R-rich phase, and the region with HR/(LR+HR)&#x2267;0.01 accounts for 10% to 90% of the area of the grain boundary triple point.

Rare earth based sintered magnet

The present invention relates to a method for producing a rare earth sintered magnet including the steps of: molding a mixture of magnetic powder containing a rare earth compound and oil-extended rubber containing oil and rubber to produce a molded body; removing the oil-extended rubber from the molded body; and calcining the molded body from which the oil-extended rubber is removed to produce a rare earth sintered magnet

Method for producing rare earth sintered magnet

A pump-equipped container () includes a tubular container body () that is made of a sheet material having flexibility and a pump device () that includes a pump body () and a nozzle portion (). A one-end section of the container body is closed off, and the pump device () is attached to the other-end section of the container body. The pump body () has an outer-circumferential-surface section () that comes into close contact with an inner circumferential surface of the other-end section () of the container body (). The pump device () is attached to the other-end section () of the container body () in such a state that the outer-circumferential-surface section () is covered with the container body () by being brought into close contact with the inner circumferential surface of the other-end section () of the container body (). The container body () is formed using a sheet material having a gas barrier property.

The invention is directed to a two-part hair cosmetic for hair dyeing or bleaching which includes a first agent containing an alkaline agent and a second agent containing hydrogen peroxide and a squeeze container for discharging a mixed solution of the first agent and the second agent. The first agent or second agent contains a foaming agent. The mixed solution thereof has a viscosity (25&#xb0; C.) of from 1 mPa&#xb7;s to 100 mPa&#xb7;s. The ratio between the total volume of the first and second agents and the inner volume of the container body is in the range of from 0.30 to 0.60.

The iconof a graphic user interface indicates the magnitude of an inputted impact by an impact pointerwhich moves as the time elapses and receives input of the impact. Magnitude of the impact received by a GUIis retained in the impact data as a product of the moving amount of the impact pointerand a scale factor, of which the value can be switched together with the indication form of a gaugedepending on the movement of a slider. Consequently, more realistic regulation of impact, e.g., half shot, can be attained when a ball is hit in a sport simulation game such as a golf game.
