摘要:
In an extraction tank, a plating solution containing rare earth metal ions is treated with an extracting solution of an extractant in a water-insoluble organic solvent. Extraction treatment is carried out by atomizing the extracting solution through a lower nozzle into the plating solution in the tank lower zone, and atomizing the plating solution through an upper nozzle into the extracting solution in the tank upper zone, for thereby bringing the plating solution in contact with the extracting solution to extract rare earth metal ions from the plating solution into the extractant for removal.

In an outer blade cutting wheel comprising an annular thin disc base of cemented carbide having an outer diameter of 80-200 mm, an inner diameter of 30-80 mm, and a thickness of 0.1-1.0 mm, and a blade section disposed on an outer periphery of the base, the blade section comprises diamond grains and/or CBN grains bound with a metal bond having a Young's modulus of 0.7-4.0×1011 Pa and has a thickness which is greater than the thickness of the base by at least 0.01 mm. The outer blade cutting wheel is capable of cutting a workpiece at a high accuracy and a reduced allowance, improves machining yields, and reduces machining costs.
摘要:
A complex alloy of at least three phases comprising a composite alloy composed of an Si single phase and an Si—Al-M alloy phase, and an L phase offers a negative electrode material. M is an element selected from transition metals and metals of Groups 4 and 5, and L is In, Sn, Sb, Pb or Mg. The negative electrode material provides a lithium ion battery with a high capacity and long life. The material itself is highly conductive and increases the energy density per volume of a lithium ion battery.
摘要:
A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.

A rare earth magnet is prepared by disposing a R1-T-B sintered body comprising a R12T14B compound as a major phase in contact with an R2-M alloy powder and effecting heat treatment for causing R2 element to diffuse into the sintered body. The alloy powder is obtained by quenching a melt containing R2 and M. R1 and R2 are rare earth elements, T is Fe and/or Co, M is selected from B, C, P, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Ag, In, Sn, Sb, Hf, Ta, W, Pt, Au, Pb, and Bi.
摘要:
A liquid-liquid extraction unit includes an extraction/separation tank (10) into which an aqueous phase in bubble form is admitted from an upper inlet (20) in one sidewall and an organic phase in bubble form is admitted from a lower inlet (30) in the one sidewall. The upward moving organic phase is contacted with the downward moving aqueous phase. After contact, the organic phase is discharged through an upper outlet (40) in an opposite sidewall and the aqueous phase is discharged through a lower outlet (50) in the opposite sidewall.

摘要:
A turn signal for a vehicle has a blue LED as a light source, and an outer cover irradiated by the blue light. The outer cover includes a molded body of a polymeric material including phosphors dispersed therein that absorb blue light and emit light. By means of the present invention, it is possible to provide a turn signal for vehicles which has improved visibility and which imparts excellent visibility and sufficient luminous intensity over a wide angle. Further, because the entire outer cover surface-emits light, uniformity of luminous intensity is ensured without subjecting the outer cover to light scattering treatment, enabling as a result preventing glare caused by light scattering treatment, making this turn signal safe without being unpleasant for pedestrians and drivers of nearby vehicles. Furthermore, because no complex optical design is necessary, this turn signal saves space and can be arranged in a vehicle.

A blue-light emitting device, or a pseudo-white-light emitting device, including an LED light source that includes, as a light emission component, blue light having a wavelength of from 420 to 490 nm. A color-renderability improvement member including a complex fluoride fluorophore that absorbs blue light and emits red light and that is represented by A2(M1-xMn)F6 (M is at least one type of tetravalent element selected from Si, Ti, Zr, Hf, Ge, and Sn; A is at least one type of alkali metal selected from Li, Na, K, Rb, and Cs and including at least Na and/or K; and x is from 0.001 to 0.3) is arranged in a location that is outside a region onto which light parallel to the light emission axis of the LED light source is emitted, said region being within a region onto which light is emitted from the LED light source.
