| 20090197014 | Apparatus and method for coating diamond on work pieces via hot filament chemical vapor deposition - There is a disclosed apparatus for coating diamond on work pieces via hot filament chemical vapor deposition. The apparatus includes a chamber, a pump for pumping air from the chamber, a pressure controller for con trolling the pressure in the chamber, a grid disposed in the chamber, a grid-bias power supply for providing a positive bias to the grid, a holder for carrying the work pieces, a holder-bias power supply for providing a negative bias to the holder, filaments provided between the grid and the carrier, a filament power supply for energizing the filaments to heat up, a programmable temperature controller for controlling the temperature in the chamber and a pipe for transferring reaction gas into the chamber. | 08-06-2009 |
| 20100225234 | Hollow-cathode plasma generator - A hollow-cathode plasma generator includes a plurality of hollow cathodes joined together and connected to a power supply for generating plasma in vacuum. Each of the hollow cathodes includes at least one fillister defined therein, a fin formed on a side of the fillister, an air-circulating tunnel in communication with the fillister and a coolant-circulating tunnel defined therein. The fillister is used to contain working gas. The fin receives negative voltage from the power supply for ionizing the working gas to generate the plasma and spread the plasma in a single direction. The working gas travels into the fillister from the air-circulating tunnel. The coolant-circulating tunnel is used to circulate coolant for cooling the hollow cathode. | 09-09-2010 |
