摘要： The present invention provides a producing method of R-T-B-based sintered magnets in which, the recovery chamber 40 includes inert gas introducing means 42, evacuating means 43, a carry-in port, a discharge port 40a, and a recovery container 60. The recovery step includes a carrying-in step of conveying a processing container 50 into the recovery chamber 40, a discharging step of discharging coarsely pulverized powder in the processing container 50 into the recovery chamber 40, a gas introducing step of introducing inert gas into the recovery chamber 40, and an alloy accommodating step of recovering the coarsely pulverized powder into the recovery container 60. Addition of pulverization aid is carried out in the alloy accommodating step. A remaining amount of coarsely pulverized powder in the recovery chamber 40, an oxygen-containing amount of the R-T-B-based sintered magnet is reduced, and magnetic properties are enhanced.
摘要翻译：本发明提供了一种RTB型烧结磁体的制造方法，其中回收室40包括惰性气体导入装置42，排气装置43，进料口，排出口40a和回收容器60.回收步骤包括将处理容器50输送到回收室40中的搬入步骤，将处理容器50中的粗粉碎的粉末排出到回收室40中的排出步骤，将惰性气体引入回收室以及将粗粉碎的粉末回收到回收容器60中的合金容纳步骤。在合金容纳步骤中进行粉碎助剂的添加。在回收室40中残留量的粉碎粉末，R-T-B系烧结磁体的含氧量降低，磁特性提高。

摘要： A dental hand-piece with an air turbine wherein a collet chuck holding a cutting tool spindle, a clamping member enough to clamp tapered chuck pawls of the collet chuck convergently from the outside, and further a moving element allowed to do the fine movement toward the outside owing to the centrifugal force acting thereon during the rotation of a rotary body are all together incorporated into the turbine rotary body supported by a shaft bearing inside a head casing, and which hand-piece is so designed in such manner that the fine movement of the moving element can provoke the sliding movement tending to clamp the chuck pawls between the collet chuck and the clamping member, is disclosed. In this hand-piece, the chuck pawls are automatically clamped at the time when the turbine rotary body starts to rotate, and the holding force of the collet chuck becomes greater to perform the reliable and steady holding of the cutting tool spindle the more high-speedily the rotary body rotates.
