摘要： A deep-hole drilling apparatus capable of preventing a tool mark from growing is provided. The deep-hole drilling apparatus provided for this purpose comprises: a tool (12) that is rotationally driven to drill a deep hole (Wa) in a work (W); an acceleration meter (19) that detects vibration of the tool (12) as the acceleration during deep hole processing; a monitoring apparatus (20) which performs frequency analysis on the acceleration detected by the acceleration meter (19) and which determines that a tool mark is produced in the deep hole (Wa) when the overall value of the whirling frequency and the bending natural frequency within a frequency range not including the torsional natural frequency on torsional vibration, constantly produced during the deep hole processing, exceeds a predetermined threshold (α); and an NC apparatus (18) that controls both revolution and feeding speed of the tool (12) on the basis of the determination made by the monitoring apparatus (20).

摘要： An object of the invention is to provide a sodium refining apparatus which has a simple constitution and does not deteriorate a solid electrolyte employed therein. The sodium refining apparatus of the invention, in which impurities contained in sodium are removed by a solid electrolyte having sodium ion conductivity, includes a bottom-closed casing made of a solid electrolyte and containing a small amount of highly pure sodium; an outer casing accommodating said bottom-closed casing and containing, outside said bottom-closed casing, impurity-containing sodium; a first electrode inserted in the impurity-containing sodium; a second electrode inserted in the highly pure sodium; and a power source for applying DC voltage to the electrodes; wherein the impurity-containing sodium and the highly pure sodium are in electrical contact with each other via the solid electrolyte.
