  • Patent number: 11254998
    Abstract: An object of the present invention is to provide a method for separating Dy and Tb from an alloy containing Dy and Tb as constitutional metals without using a solvent extraction method. The method of the present invention as a means for resolution is characterized by comprising vaporizing Dy by subjecting the alloy to a heat treatment in an atmosphere of a pressure Pt(Pa) that, when a Dy—Tb composition in the alloy is DyxTby (atomic composition ratio) and a heat treatment temperature is t, satisfies formula 1: PtTb<Pt<PtDy×(x/(x+y)), wherein PtDy is a vapor pressure (Pa) of Dy alone at the temperature t and PtTb is a vapor pressure (Pa) of Tb alone at the temperature t.

  • Patent number: 11209298
    Abstract: Mass flow controllers and methods for controlling mass flow controllers are disclosed. A method includes providing a gas through a thermal mass flow sensor of the mass flow controller and processing a flow sensor signal from the thermal mass flow sensor of the mass flow controller to produce a measured flow signal. The measured flow signal is corrected to produce a corrected flow signal by gradually changing non-linearity correction to the measured flow signal when a flow rate of the gas changes. A valve of the mass flow controller is controlled using the corrected flow signal and a setpoint signal.
