Title: Manufacture of sintered rare earth element magnet
Inventor: TAKESHITA TAKUO
IPC: H01F1/08
Filed: 1985-12-05
Abstract: PURPOSE:To prevent a rare earth element alloy from being contaminated with oxygen and carbon during crushing by occluding hydrogen to the rare earth element alloy of a stock, and crushing the rare earth element alloy which has occluded the hydrogen in hydrogen atmosphere or in inert gas atmosphere of argon or the like. CONSTITUTION:To crush a rare earth element alloy, hydrogen is occluded in advance to the rare earth element alloy, and the alloy which has occluded the hydrogen is crushed at once in the form of fine powder in hydrogen gas or inert gas atmosphere in one vessel without externally removing the alloy which has occluded the hydrogen on the way. The rare earth element alloy fine powder which has occluded the hydrogen or the rare earth element alloy fine powder which has dehydrogenated is formed and sintered as stock powder to manufacture the sintered rare earth element magnet. Since the rare earth element alloy is effectively prevented from being contaminated with the oxygen or carbon until the rare earth element alloy becomes a magnet and fine powder containing regular particle size is prepared in crushing step, the magnet having excellent magnetic properties can be formed. The hydrogen occluded into the rare earth element alloy is discharged to activate particles of the rare earth element alloy fine powder, thereby enhancing sintering and molding properties of the fine powder.

Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To improve workability by inserting a spacer, which has a face plate, wide enough to embed a channel in channel steel, provided with a bent portion having a vertical channel, into the channel in the channel steel used as a column between partition walls. SOLUTION: A spacer 20 which has a face plate 21, wide enough to embed a groove 13c in a channel steel 13, provided with a bent portion 23 having a vertical channel and an engagement portion 22 provided at both ends in the cross direction of the face plate 21 to be elastically engaged with both side edges of the channel 13c in the channel steel 13 is formed.

IPC: G02B6/293
Filed: 1988-11-01
Abstract: PURPOSE:To obviate the decrease in the refractive index of a stress imparting part and the decrease in the insertion loss and to make stable production of the above coupler by adding fluorine to the clad part to provide the refractive index nearly equal to the refractive index of B2O3 to the clad part. CONSTITUTION:The fluorine is added to the SiO2 glass of the clad part 14b by which the refractive indices of the clad part 14b and the stress imparting part 15 added with the B2O3 are nearly equaled. The coefft. of thermal expansion of the clad part 14b added with the fluorine does not increase as compared with the coefft. of thermal expansion of the SiO2 glass and, therefore, the difference in the coefft. of thermal expansion between the clad part 14b and the stress imparting part 15 is prevented from decreasing. The need for adding an additive for adjusting the refractive index such as GeO2 to the stress imparting part 15 of the base material for the optical fiber is, therefore, eliminated. The polarization maintaining optical fiber type optical coupler of a low insertion loss is economically produced with good reproducibility at a high yield.
