摘要： In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle having a plurality of slits is combined with a plurality of cutoff abrasive blades coaxially mounted on a rotating shaft, each said blade comprising a base disk and a peripheral cutting part. The slits in the feed nozzle into which the outer peripheral portions of cutoff abrasive blades are inserted serve to restrict any axial run-out of the cutoff abrasive blades during rotation. Cutting fluid is fed from the feed nozzle through slits to the rotating cutoff abrasive blades and eventually to points of cutoff machining on the magnet block.

摘要： In the present invention, in producing a SiC single crystal in accordance with a solution method, a crucible containing SiC as a main component and having an oxygen content of 100 ppm or less is used as the crucible to be used as a container for a Si—C solution. In another embodiment, a sintered body containing SiC as a main component and having an oxygen content of 100 ppm or less is placed in the crucible to be used as a container for a Si—C solution. The SiC crucible and SiC sintered body are obtained by molding and baking a SiC raw-material powder having an oxygen content of 2000 ppm or less. SiC, which is the main component of these, serves as a source for Si and C and allows Si and C to elute into the Si—C solution by heating.

摘要： Provided is a wavelength conversion member in which the following are dispersed in a thermoplastic resin: a LuYAG fluorescent material that is represented by (Y1-α-βLuαCeβ)3Al5O12 (in which α is a positive number between 0.3-0.8 inclusive and β is a positive number between 0.01-0.05 inclusive), that emits yellow-green light as a result of excitation by blue light, and that has a diffraction peak within a range in which the diffraction angle 2θ in X-ray diffraction by the Kα1 line of Cu is 52.9° to 53.2° inclusive; and a KSF fluorescent material that is represented by K2(Si1-xMnx)F6 (in which x is a positive number between 0.001 and 0.3 inclusive) and that emits red light as a result of excitation by blue light. The content of the KSF fluorescent material in the wavelength conversion member is 1 to 5 times the content of the LuYAG fluorescent material by mass ratio. The wavelength conversion member makes it possible to provide a light-emitting device that has small color deviation, that is suitable as a lighting device, that emits white light, and that has good color rendering properties in a color temperature range of 4,000-6,500K, i.e., the color temperature range from white to daylight color.

摘要： An outdoor luminaire comprising a blue LED chip having a maximum peak at a wavelength of 420-480 nm and a phosphor layer disposed forward of the LED chip in its emission direction is provided. The phosphor layer comprises a phosphor of the formula: Lu3Al5O12:Ce3+ which is activated with up to 1 mol % of Ce relative to Lu, the phosphor being dispersed in a resin. In scotopic and mesopic vision conditions, the luminaire produces illumination affording brighter lighting, higher visual perception and brightness over a broader area.

摘要： In the present invention, a crucible formed of SiC as a main component is used as a container for a Si—C solution. A metal element M (M is at least one metal element selected from at least one of a first group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Lu, a second group consisting of Ti, V, Cr, Mn, Fe, Co, Ni and Cu and a third group consisting of Al, Ga, Ge, Sn, Pb and Zn) is added to the Si—C solution and the crucible is heated to elute Si and C, which are derived from a main component SiC of the crucible, from a high-temperature surface region of the crucible in contact with the Si—C solution, into the Si—C solution. In this way, precipitation of a SiC polycrystal on a surface of the crucible in contact with the Si—C solution is suppressed.

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.
