Abstract: A collection process for precipitated powder substance is mainly for storing toxic or highly radioactive powder or dust in air and involves collection operation in water or other liquid to collect powder insoluble to the liquid and heavier than the liquid. To be suitable for underwater operation, a powder precipitation bag is provided with an innovative powder collection can at its bottom. New powder collection can has a mesh filter in its bottom and two-stage structure. After completion of powder collection, the collection can is pulled up from the water and dried to reduce powder volume and form powder lumps. Then, the top half is removed, so the collection can is fully filled with powder lumps. The newly designed powder can increases storage efficiency and reduces waste of space by accommodating more powder lumps than traditional powder can. With the same total amount of powder, the new powder can enables fewer number of storage cans.

Abstract: A method for inputting characters is provided. In the present invention, a touch-sensitive keypad is used for a hand-held electronic device to enter a text input mode. Multiple characters represented by a key are displayed by turns and repeatedly over a predefined period of time. Thus, the number of times for operating the keypad can be reduced and the efficiency of inputting characters can be improved. Further, the input of English alphabets and Arabic numerals can be switched automatically through alternatively displaying the characters. Therefore, the convenience of using a hand-held electronic device can be enhanced.
