ELECTRON BEAM FURNACE DEVICE | 2 |
| 20090161719 | LINEAR ELECTRON SOURCE, EVAPORATOR USING LINEAR ELECTRON SOURCE, AND APPLICATIONS OF ELECTRON SOURCES - An evaporation apparatus for evaporating a material to be deposited is described. The evaporation apparatus includes at least one evaporation crucible having a body with an area for receiving the material to be deposited at one side; a linear electron source being positioned adjacent to the evaporation crucible for impingement of an electron beam on another side. The linear electron source includes a housing acting as a first electrode, the housing having side walls; slit opening in the housing for trespassing of a electron beam, the slit opening defining a length direction of the source; a second electrode being arranged within the housing and having a first side facing the slit opening; and at least one gas supply for providing a gas into the housing, wherein the first electrode is the anode and the second electrode is the cathode. | 06-25-2009 |
| 20140294035 | ELECTRON BEAM MELTING FURNACE AND METHOD FOR OPERATING SAME - An electron beam is accurately emitted to a pre-set location on a molten metal pool formed in a hearth or a mold arranged in an electron beam melting furnace. The present invention provides a method for operating an electron beam melting furnace, the furnace includes: a hearth and a mold for holding molten metal, an electron gun for keeping the metal as a molten state, an electron beam controlling means for controlling direction of the electron beam, an image sensor for molten metal, and an operating means, and the method includes: a step of inputting coordinates in the electron beam controlling means at which an electron beam is to be emitted on molten metal, a step of emitting the electron beam on the molten metal, a step of detecting a high electron beam intensity spot generated by emitting an electron beam on the molten metal by the image sensor, a step of calculating coordinates of high electron beam intensity based on the detected signal by the operating means, a step of calculating differences between the coordinates of emission and the coordinates of high electron beam intensity spot, a step of inputting the difference in the electron beam controlling means, and a step of controlling the location of electron beam spot so that the difference be not more than pre-set value. | 10-02-2014 |
