    Abstract: A fan speed control circuit is used for controlling rotation speed of a fan. The fan speed control circuit receives a pulse width modulation (PWM) signal from a system and comprises a programmable control unit and a current control unit. The programmable control unit receives the PWM signal, is connected to a Hall element for receiving a voltage signal therefrom, and provides a control signal. The current control unit takes the control signal to control current flowing through a stator coil unit of the fan so as to control the speed of the fan. The programmable control unit has a program written for the PWM signal, and when the fan speed control circuit is used in another system with a different PWM signal, the programmable control unit can be given a new program for the different PWM signal for controlling the speed of the fan.

  • BACKSIDE ELECTRODE LAYER AND FABRICATING METHOD THEREOF
    Publication number: 20090308446
    Abstract: A backside electrode layer and a fabricating method thereof are applicable for fabricating a solar cell. The backside electrode layer includes a first electrode layer and a second electrode layer. The first electrode layer is formed on a substrate and has a thickness smaller than 15 ?m. The second electrode layer having patterns is formed on the first electrode layer. The first and second electrode layers are fabricated by a cofiring process. As the thickness of the first electrode layer is decreased and the second electrode layer is not a full coverage layer, the material usage of each electrode layer is reduced and the fabrication cost thereof is leveled down. Besides, a thinner electrode layer may avoid warp after the cofiring process.
