Title:
ELECTRON-EMITTING DEVICE AND ELECTRON-EMITTING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2000/030983
Kind Code:
A1
Abstract:
An electron-emitting device (37) comprises a primary and a secondary coil wound on an I-core, an E-core combined with the I-core and a single output terminal (41) extended from one end of the secondary coil. An electron-emitting electrode (38) comprises a stainless steel pipe (31), an insulator-coated conductor (33) inserted in the pipe, and tourmaline powder (32) filled in the gap between the pipe and the conductor. The stainless steel pipe (31) is enclosed in a polyethylene pipe (34), and the opening of the stainless pipe (31) and polyethylene pipe (34) is closed by silicon resin (35). The electron-emitting electrode (38) connected with the output terminal (41) of the electron-emitting device (37) is soaked in an object, which is in turn charged negatively and activated by high electrostatic potential.
