    摘要： There are provided a rare-earth permanent magnet and a manufacturing method of the rare-earth permanent magnet capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder, and the magnet powder is mixed with a binder made of a hydrocarbon to prepare slurry 12, and one or more kinds of organic solvents selected from a group of organic compounds consisting of hydrocarbons. Next, the slurry 12 is formed into a sheet-like shape to obtain a green sheet 13. After that, the green sheet 13 is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to cause depolymerization reaction or the like to the binder, which turns into monomer and is removed. The green sheet 13 with the binder removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

    摘要： There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder. Next, a mixture is prepared by mixing the magnet powder and a binder made of a fatty acid methyl ester and/or one of or a blend of polymers and copolymers each composed of monomers satisfying a given condition. Next, the mixture is formed into a sheet-like shape to obtain a green sheet. After that, the green sheet is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to remove the binder by causing depolymerization reaction or the like to the binder, which turns into monomer. The green sheet from which the binder has been removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

    摘要： There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of boosting productivity by improving thickness accuracy of a green sheet. In the method, magnet material is milled into magnet powder, and the magnet powder and a binder are mixed to obtain a mixture including 1 to 40 wt % of the binder therein. Next, by high precision coating of a substrate with the mixture, a green sheet is obtained at thickness precision within a margin of error of plus or minus 5% with reference to a designed value. Thereafter, the green sheet is held for predetermined time at binder decomposition temperature in non-oxidizing atmosphere, whereby depolymerization reaction or the like changes the binder into monomer and thus removes the binder. The green sheet with the binder removed therefrom undergoes pressure sintering such as SPS method so as to obtain a permanent magnet 1.

    摘要： The present invention relates to a light source apparatus that has a base structure capable of generating SC light and further having a structure that enables the shaping of the spectral waveform of the SC light, power adjustment of the SC light, or adjustment of the frequency of repetition of the pulse train that contains the SC light. For example, a light source apparatus that enables shaping of spectral waveforms comprises a seed light source that emits seed light which is a pulse train or continuous light; an optical fiber that generates SC light from the seed light, and spectrum shaping means for completely or partially changing the spectral waveform of the SC light. The shaping of the spectral waveform changes the maximum power of the seed light by changing the optical coupling efficiency of the seed light source and optical fiber, for example, thereby suitably deforms the spectrum of the SC light.
