摘要： A multi-phase motor control method controls a multi-phase motor which includes multiple nodes respectively receiving a corresponding number of driving voltage signals to control a rotation of a rotor. The motor control method includes: sensing a signal phase of a current signal corresponding to at least one node, for example by sensing a zero-crossing point of the current signal; determining a reference phase for the current signal; calculating a phase difference between the signal phase and the reference phase; and controlling a phase switching frequency of the stator according to the phase difference, such that the signal phase is close to or in phase with the reference phase, to thereby obtain an optimum rotation speed of the rotor corresponding to a given driving voltage. The present invention also provides a multi-phase motor control device using the motor control method.

摘要： A method and apparatus for dynamically adjusting a dead time of a BLDC motor during a phase change detect the winding current of the BLDC motor during the dead time, and terminate the dead time when the winding current is detected to be substantially or close to zero. Thus, the method and apparatus can optimize the dead time and switch the BLDC motor between two phases at a zero-current point, without reducing the maximum rotation speed of the BLDC motor.

摘要： A display structure. The display structure has a substrate, a panel, a lamp disposed on the panel, a lead wire connected to the lamp, and an intermediate disposed between the lead wire and the substrate. The substrate has a first sliding portion and a first positioning portion. The intermediate has a clamping portion, a second sliding portion and a second positioning portion. When the lead wire is placed in the clamping portion, the intermediate is moved to an engaging position on the substrate by sliding the second sliding portion on the first sliding portion. Thus, the second positioning portion is engaged to the first positioning portion, and the intermediate is elastically deformed so that the lead wire is wedged by the clamping portion.

摘要： A planar inverted-cone susceptor, preferably made of silicon carbide, inversely disposed between a substrate and a holder of the Rapid Thermal Processor (RTP) so as to perform heat compensation on the substrate. Because the substrate is directly supported by the inverted-cone susceptor, heat stored in the wafer can be rapidly received by the inverted-cone susceptor. Thermal stress and thermal gradient can be effectively decreased in the wafer.

摘要： A display unit comprises a case, a panel, a lamp, an intermediate and a lead wire. The lamp is placed next to the panel, and the lead wire is electrically connected to the lamp to form a conjunctive portion. The conjunctive portion is placed in a mold and integrally covered with the intermediate. When the lead wire is pulled by an abnormal or abrupt force, the majority of the force can be absorbed by the intermediate pressed on the case, and the lead wire can remain fixed to the lamp.
