20140100103 | METHOD OF PRODUCING CARBIDE AND CARBON NITRIDE POWDERS CONTAINING BINDER, AND CERMET OBTAINED FROM THE SAME - Disclosed is a method of producing carbide and carbon nitride powders containing a binder, and cermet obtained from the same. | 04-10-2014 |
20140114626 | METHOD OF CALCULATING NUMERIC MODEL FOR INTERPRETATION OF METAL HYDRIDE TANK - Disclosed is a method of calculating a numeric model for interpretation of a metal hydride tank. The best possible simpljfied algorithm is applied through a simple measuring process, thereby calculating a numeric model for various metal hydride tank systems storing hydrogen, so that temperature variation depending on the reaction with hydrogen and the reacted. quantity of the hydrogen. are calculated with respect to the various metal hydride tank systems by calculating only the numeric model. The method. includes (a) charging a metal hydride (MH) alloy in a metal hydride tank system under a preset temperature condition, (b) measuring temperature variation and a reaction rate between MH alloy and hydrogen, and concentration of the hydrogen of the MH alloy by supplying or emitting the hydrogen, and (c) calculating a numeric model for the temperature variation, the reaction rate, and the concentration of the hydrogen based on data measured through step (b). | 04-24-2014 |
20140207387 | METHOD OF ANALYZING NUMERIC MODEL FOR METAL HYDRIDE TANK - A method of analyzing a numeric model for a metal hydride tank, which calculates the temperature change and the change of a reaction rate and the hydrogen concentration in the alloy resulting from a hydrogen reaction based on various user conditions with respect to metal hydride (MH) alloy tanks having various shapes when MH alloy tanks are actually used. The method includes (a) inputting a temperature (T), a real reaction flow rate (Q | 07-24-2014 |
