摘要： Provided are an apparatus for producing inorganic powder, and a method of producing inorganic powder by using such. The apparatus includes a vaporization part where a condensed-phase precursor is vaporized to obtain a gas-phase precursor, a partial precipitation part where the gas-phase precursor obtained in the vaporization part is partially precipitated to a condensed phase, and a reaction part where the gas-phase precursor remaining after being partially precipitated to a condensed phase in the partial precipitation part reacts with a reaction gas to obtain inorganic powder. An equilibrium vapor pressure of the gas-phase precursor in the partial precipitation part is lower than a vapor pressure of the gas-phase precursor obtained in the vaporization part, and an equilibrium vapor pressure of the precursor in the reaction part is equal to or higher than a vapor pressure of the gas-phase precursor partially precipitated to a condensed phase in the partial precipitation part.

摘要： A machining device can lengthen the lifespan of a tool and improve the machining quality of a workpiece by managing the amount of wear of the tool by machining the workpiece using the other portion of the tool when a portion of the tool is worn and the machining performance of the tool is decreased. The machining device includes: a tool-moving unit coupled to a machining unit to change the position of the tool with respect to the workpiece; a supporting unit supporting the workpiece; a sensor unit disposed at the machining unit and measuring a current amount supplied to a machining motor operating the tool, or an operation force of the tool; and a control unit receiving a measurement signal from the sensor unit and transmitting a control signal to the tool-moving unit and the supporting unit.
