The production method of carbon nano structure comprising fluidizing a material gas and catalyst microparticles in the reactor so that the material gas and the catalyst microparticles are brought into contact with each other, wherein said catalyst microparticles are suspended by the instantaneous spraying of the high-pressure gas, and then the suspension effect of the catalyst microparticles is stopped so that the catalyst microparticles naturally fall. The particle diameter of the catalyst microparticles is thus selected. With this arrangement, only the selected catalyst microparticles with the desired diameter are supplied to the reactor.

Abstract: A servo device is provided which includes a drive source made of a brushless motor. A DC motor driving integrated circuit produces output signals and controls the output of a three-phase brushless motor driving integrated circuit to drive the brush less motor. A selection switching section detects information regarding the rotational speed of the brushless motor. The selection switching section extracts the counter electromotive voltage of the brushless motor, feeds the voltage back to the DC motor driving integrated circuit and PWM controls a drive signal output from the three-phase brushless motor driving integrated circuit. This allows the brushless motor to be easily applied to the servo device.
