Title: Vacuum pump
Inventor: NISHIUCHI AKIRA
IPC: F04D19/04
Filed: 1988-04-15
Abstract: PURPOSE:To prevent a reaction product from closing the exhaust passage of a motor-driven pump mechanism in advance by providing an induction heating means for the exhaust passage leading to an outlet which is opened to air, so as to vaporize the reaction product which contaminates the surface of the exhaust passage. CONSTITUTION:When the rotor 9 of a pump mechanism 7 is rotated by a motor 11 through a drive shaft 14, air taken from an inlet 5 is gradually compressed in a flow passage between a stator 8 and the rotor 9, so as to be exhausted from an outlet 6' through an exhaust passage 6. In this exhausting process, where an inlet side is, for example, connected to a semiconductor device, that's, an aluminum dry etching device, aluminum chloride is produced as a reaction product after etching. In this case, a heating coil 18 is provided for the exhaust passage 6, and a high frequency electric current flows thereto to generate innumerable eddy currents on the wall surface of the metallic exhaust passage 6, so that the exhaust passage 6 is heated. Thus, the reaction product can be vaporized so as to be prevented from contaminating the inner wall of the exhaust passage.
