Title: Preparation of rapid-solidification hydrogen-storing alloy powder material and the production device
Inventor: CHEN YU
IPC: H01M4/38
Filed: 1996-12-31
Granted: 2001-05-01
Abstract: This invention describes the preparation of a rapid-solidification hydrogen-storing alloy powder material and the production device. Especially, the method utilizes vacuum or Ar gas protection to smelt the hydrogen-storing alloy furnace material. The smelted material flows into atomization chamber at specific temperature and speed via a central embraced injection tube to be atomized into powder of 120 to 350 mesh by high-pressure inert gas atomizer. Then it undergoes cooling down, sieving and sending into the hydrogen treatment chamber for hydrogen treatment and further sieving and barreling. The use of protecting gas such as Ar and N2 can speed up the smelting process, reduce the oxidation of the molten metals by the gases in the furnace and also ensure the heating homogeneity of the melting pond, which favors the production of the hydrogen-storing alloy powder with the micro-crystalline structure of low degree of inclusion and segregation. The method provided in the invention can integrate the smelting, powdering and hydrogen treating of the hydrogen storing alloy material and thus allows continuous adding raw materials, continuous powdering for mass production of hydrogen-storing alloy powder material.

The output of the second inverter is a POR signal that can be used on the reset input of a logic device, which is sensitive to the initial state in the integrated circuit so as to be set at a specific state that has been recognized when the voltage VDD is turned on. The proposed POR circuit in the invention includes an NMOS transistor, in which its gate is connected to the output of the first inverter, its drain is connected to the input of the first inverter, and its source is connected to the second power source line terminal. The NMOS transistor has the function of accelerating the discharging operation of the input terminal potential for the first inverter after a voltage VDD is turned on and becomes stable for a period of time. In addition, the proposed POR circuit in this invention includes the second diode that is connected in parallel with the first diode. The purpose of the second diode is to clamp the voltage difference between the electric potential of the common connection point, which is between the capacitor and the resistor, and the electric potential of the input terminal of the first inverter.
