摘要： A graphite cathode and a graphite anode are placed opposite each other through an insulating plate having a notch. A voltage is applied between both of the electrodes to generate arc discharge at the notch of the insulating plate. A given area of the graphite anode is evaporated from an electrode point of the arc discharge, and simultaneously an arc jet is generated from the notch. Thereby, a carbon nanoparticle comprising soot of carbon nanomaterial containing carbon nanohorn is generated. The soot is deposited on a recovering plate for recovery.

摘要： A power supply circuit for plasma generation by which a large quantity of generated plasma can be smoothly obtained without increasing the sizes of an apparatus. An electric discharge generating electrode is composed of two or more first electrodes and one or more second electrodes. An LC series circuit is provided by connecting a capacitor C and a coil L in series between one of outputs of an alternating high voltage generating circuit which generates an alternating high voltage to be applied between the electrodes of electric discharge generating electrode, and the first electrode. When electricity is discharged in one of the electrode pair, voltage drop is suppressed by the coil, and since electric discharge from the other electrode pair is induced without being disturbed, a large quantity of plasma can be smoothly generated by common use of the alternating high voltage generating circuit.

摘要： A method of instantaneously forming a surface of an arc-treated material mainly including graphite into nano-tubes due to arc discharge carried out using a unit like a welding arc torch or the like without necessarily requiring a processing container, resulting in the nano-tube being applied to an electron emission source. A torch electrode acting as a first electrode and the arc-treated material made of graphite and acting as a second electrode are arranged opposite to each other. A potential is applied between both electrodes to generate arc discharge therebetween. A mask having an opening pattern is arranged on the arc-treated material, so that only graphite positioned on portions of a surface of the arc-treated material corresponding to openings of the mask are exposed to arc, to thereby be formed into nano-tubes.

摘要： A plasma generator for forming a thin film comprises a cathode (4) for supplying constituent particles of an arc plasma and a trigger-and-anode (6) for starting and sustaining the arc plasma. The cathode surface (4a) of the cathode (4) is flat or finely irregular, and the anode surface (6c) of the trigger-and-anode (6) brought into contact with the cathode surface (4a) is flat. The anode surface (6c) is so arranged as to be brought into contact with the whole cathode surface (4a) when plasma is started. The contact point between a fine projection end (4b) of the cathode surface (4a) and the anode surface (6c) is made a plasma emission point. When the projection is consumed by plasma emission, another projection end which can be brought into contact with the anode surface (6c) is used as another plasma emission point, thus enabling intermittent operation of persistently repeating the sequence operation.
