Title: Brushless motor drive circuit having low noise and high efficiency
Inventor: MITSUDA TSUYOSHI
IPC: H02P6/28
Filed: 2001-10-08
Granted: 2003-07-21
Abstract: A motor drive circuit for driving a brushless motor having a rotor and exciting coils of respective phases. A square wave rotor position signal for each phase is produced wherein a half period of the rotor position signal corresponds to a time period from a polarity inversion of an induced voltage of the exciting coil to the next polarity inversion of the induced voltage. Based on the rotor position signal, excitation of the exciting coils is performed by controlling switching elements for conducting excitation currents by using square wave on-control and/or pulse width converted square wave pulse width modulation (PWM) control. A pulse width converted sinusoidal wave PWM signal is generated whose pulse width varies according to a sinusoidal function. Excitation of the exciting coils is controlled based on the pulse width converted sinusoidal wave PWM signal immediately before and after the square wave on-controlled portions and/or the pulse width converted square wave PWM controlled portions.

Abstract: Subject of the present invention is to provide a production method for a group III nitride compound semiconductor, with which pits per wafer are reduced.

After a bottom part S of the pit is covered by the second group III nitride compound semiconductor 4 in the manner of lateral growth, epitaxial growth is conducted again for forming a first group III nitride compound semiconductor layer 32 (c). Thus, the group III nitride compound semiconductor 32 is formed quickly in a recess, and a very flat (c) surface is formed (d).
