Granted: 2004-06-01
Abstract: The present invention relates to a control method for decreasing the stable rotation speed of a ball auto-balance system, wherein a rotation speed omegas is determined based on a predetermined manner, and the rotation speed omegas is between an unstable ball critical rotation speed omegac and a working rotation speed omega. Furthermore, acceleration is provided to make the ball pass the unstable ball critical rotation speed omegac to accelerate a spindle motor to rotate at the rotation speed omegas, and then the acceleration of the spindle motor is decreased to make the ball reach at a stable position after a short period of time. Then, the spindle motor is accelerated again to rotate at the working rotation speed omega, thereby decreasing the stable rotation speed of the ball auto-balance system, so as to achieve the purpose of reducing the vibration before the spindle motor rotates to the working rotation speed, and thus effectively increasing the lifetime of bearing.

Filed: 2002-07-09
Granted: 2003-11-11
Abstract: A method of simulating a memory transistor is provided. An Id-Vcg characteristic is obtained by actual measurement in step s2, and an Id-Vfg characteristic is obtained by actual measurement in step s4. Based on the obtained Id-Vcg and Id-Vfg characteristics, the value of a capacitance (Cfc) for use in circuit simulation of the memory transistor is determined in step s5. In step s14, the circuit simulation is performed using the value of the capacitance (Cfc) determined in step s5. This allows a simulated value to reliably approach a measured value since the determined capacitance (Cfc) is based on a result of actual measurement of the characteristics of the memory transistor.

The upper end of the pillar is covered by a cap and sidewalls of selectively etchable materials so that gate and source connection openings can also be made by selective etching with good registration tolerance. A dimension of the pillar in a direction parallel to the chip surface is defined by a distance between isolation regions and selective etching and height of the pillar is defined by thickness of a sacrificial layer.
