| 20120280167 | FERRITE MAGNETIC MATERIAL, FERRITE MAGNET, AND FERRITE SINTERED MAGNET - A ferrite magnet and a ferrite sintered magnet including a ferrite magnetic material are provided. A main phase of the ferrite magnetic material includes a ferrite phase having a hexagonal crystal structure, and metal element composition expressed by Ca1-w-x-yR wSr xBayFezMm wherein 0.25| 11-08-2012 | |
| 20130027160 | SINTERED MAGNET AND METHOD FOR PRODUCING THE SINTERED MAGNET - The present invention aims to ensure strength of a thin-walled sintered magnet. A sintered magnet is a ferrite sintered magnet made by sintering a magnetic material. A magnetic powder mixture obtained by mixing magnetic powder with a binder resin is injection-molded into a mold with a magnetic field applied thereto to produce a molded body, which is then sintered to produce the sintered magnet. The sintered magnet has a thickness of 3.5 mm or less in the position of center of gravity thereof. The sintered magnet has a surface roughness Rz of 0.1 or more and 2.5 μm or less. The surface roughness Rz is a 10 point average roughness. | 01-31-2013 |
| 20140051799 | MODIFIED CONJUGATED DIENE RUBBER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION - A method containing a step of reacting a conjugated diene polymer having an alkali metal or alkaline earth metal active end with a hydrocarbyloxysilane compound having one or more of each of the following functional groups I and II in its molecule to obtain a modified conjugated diene polymer containing a functional group II, and a step of mixing the modified conjugated diene polymer and a compound such as organic acid. A modified conjugated diene rubber which can be used as a raw material of a cross-linked rubber which can be used in tire treads and the like and can enhance low fuel consumption performance is provided. The functional group I is a hydrocarbyloxysilyl group. The functional group II is a nitrogen-containing group in which both of two hydrogen atoms of a primary amino group are substituted with protective groups. | 02-20-2014 |
