<P>PROBLEM TO BE SOLVED: To provide a safety electron emission apparatus usable for various applications. <P>SOLUTION: Electron emission electrodes are on the center of a cross-section of a nozzle 2 and the center side of an inner surface of the cylinder of the nozzle. A power source 7 and voltage are applied regardless of AC or DC and high or low, respectively. In the electron emission apparatus, a material selected for a specific purpose among the applied substances of various elements such as metals, powders including metals, or soft bodies including other safety material powders or liquids, is fed into a container and is set in a space in which electrons or ions can be passed through on the way of the nozzle. The liquid is lapped by a thin film, and the powder is put in a cartridge 5 having an inlet/outlet composed in the net state or surface-perforated state, or is solidified by mixing with a resin or the like to be set on the way of the nozzle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
