摘要:
A rare earth bonded magnet comprising a rare earth magnet powder bonded with a binder resin is manufactured by extrusion or injection molding. A rare earth bonded magnet manufactured by extrusion molding has a rare earth magnet powder content of 78.1 to 83.0 percent by volume. A rare earth bonded magnet manufactured by injection molding has a rare earth magnet powder content of 68.0 to 76.0 percent by volume. Preferably, the rare earth metal powder is at least one of Sm--Co alloys, R--Fe--B alloys wherein R is at least one of rare earth elements including Y, and Sm--Fe--N alloys. Preferably, the thermoplastic resin include polyamide, liquid crystal polymer, and Polyphenylene sulfide. Preferably, the rare earth bonded metal has a void ratio of 2 percent by volume or less. A rare earth bonded magnet is manufactured by kneading a rare earth magnetic composition comprising a rare earth magnet powder and a thermoplastic resin, and by extruding or injecting the mixture after kneading. A rare earth magnetic composition used for extrusion molding contains a rare earth metal powder of 77.6 to 82.5 percent by volume, and a rare earth magnetic composition used for injection molding contains a rare earth metal powder of 67.6 to 75.5 percent by volume. Preferably, such rare earth magnetic compositions further comprise an antioxidant, such as a chelating agent. Thus, a rare earth bonded magnet showing excellent moldability and magnetic properties and high mechanical strength at a minimum binding resin can be obtained.

A composition for a rare earth bonded magnet, the rare earth bonded magnet and the method for manufacturing the rare earth bonded magnet are provided that produce little decline in mechanical strength caused by the addition of a lubricant and have excellent molding properties. The rare earth bonded magnet of the present invention is manufactured from the composition for the magnet that contains rare earth magnetic powder, binding resin containing thermoplastic resin, and fluorine-based resin powder, by compaction molding, extrusion molding or injection molding. The fluorine-based resin powder has the properties of improving mainly lubrication between a molding and a metallic mold. The content of the fluorine-based resin powder in the composition for the rare earth bonded magnet is preferably less than 20 vol % relative to the thermoplastic resin, and the particle diameter of the fluorine-based resin powder is preferably 2-30 &mgr;m.

摘要:
The present invention provides a spread illuminating apparatus which can ensure uniform brightness over its entire screen. A light reflection-diffusion layer is formed on a light conductive member at a face provided with an optical path conversion means. Light emitted from spot-like light sources is reflected efficiently by the light reflection-diffusion layer toward a transparent substrate, and light intensity degrades in a substantially linear manner with the increase in distance from respective spot-like light sources. Sharp change of brightness on an observation surface can be prevented due to the light intensity degrading linearly.

It is an object of the present invention to provide an image transform apparatus and an image transform program which can reduce a computation load for transforming a luminance image to a brightness image. The present invention attains the object by performing wavelet resolution of the luminance image first to generate J pieces (J is an integer equal to two or more) of sub band images (S2), transforming a luminance value of each pixel of the sub band images to a brightness impression value based on a predetermined relation between luminance and brightness impression (S4), and then performing wavelet synthesis of K pieces (K is an integer equal to two or more; K≦J) of sub band images having been subjected to the transformation of the luminance values to the brightness impression values, to generate a brightness image (S5).
