    摘要: A method for recovering rare earth elements and cobalt from a rare earth-iron alloy containing cobalt is disclosed, including the steps of:a preparing a slurry of the rare earth-iron alloy containing cobalt,adding a diluted nitric acid solution to the slurry with air being introduced into the slurry, while maintaining pH of a resulting mixture at 5 or higher to dissolve metals including rare earth metals and cobalt at 50.degree. C. or lower, andseparating an undissolved residue containing iron from a rare earth-containing nitrate solution by filtration.

    摘要: To make a rear cushion device compact and lightweight, a rear cushion device is accommodated inside a track belt of an endless track device and includes a separate damper and cushion spring. The damper is slightly inclined downward towards the front side and is supported at its upper end by a floor. The cushion spring is positioned substantially upright in its compressed state.

    摘要: First rear swing arms are pivotably supported at their front ends to a drive shaft on which drive wheels are mounted. The rear ends of the first rear swing arms are pivotably supported through a shaft to the front ends of side rails, and first idlers are mounted on the shaft. Second idlers are mounted on a shaft to which the rear ends of the side rails are supported, and second rear swing arms are supported at their lower ends to shafts supported to the rear ends of the side rails. The upper ends of the second rear swing arms are supported to a shaft supported to a floor. A track belt is wrapped around the drive wheels and the idlers. Sliders and are individually mounted on the first rear swing arms and the side rails, respectively.

    摘要: This invention provides a tetrafluoroethylene (TFE) copolymer resin powder composition capable, upon rotational lining, of generating a corrosion-resistant, nonstick film, which is a thick film on a metal or a like substrate, essentially free of gas bubbles, and excellent in adhesion and peel resistance. The TFE-copolymer resin powder composition comprises granules which comprise particles of a TFE/perfluoro(alkyl vinyl ether) copolymer (PFA), polyphenylene sulfide (PPS) particles having an average particle size of 0.3-50 .mu.m, and a heat resistant filler. This invention also provides a process for manufacturing the TFE copolymer resin powder composition comprising either (1) granulating a mixture of PFA particles, PPS and a heat resistant filler in the presence of water and an organic liquid, or (2) mixing PFA, PPS, and a heat-resistant filler, compression-molding, and pulverizing.
