Abstract: An assembly structure includes a first assembly member, a second assembly member, a first sliding member and a second sliding member. The first assembly member includes a first engaging portion and a second engaging portion. The first sliding member includes a first through hole and a first engaging recess. The first engaging portion is disposed in the first through hole. The second sliding member includes a second through hole and a second engaging recess. The second engaging portion is disposed in the second through hole. The first sliding member slides toward a first direction to drive the second sliding member to slide toward a second direction, such that the first engaging portion engages with the first engaging recess and the second engaging portion engages with the second engaging recess.

Abstract: A motor control device includes a rotation speed control circuit, a voltage transforming circuit, a buffering circuit and a driving circuit. The rotation speed control circuit provides a rotation speed control signal. The voltage transforming circuit is electrically connected to the rotation speed control circuit and transforms the rotation speed control signal to a speed control voltage signal. The buffering circuit, electrically connected to the voltage transforming circuit, receives the speed control voltage signal and delays or buffers output of the speed control voltage signal. The driving circuit, electrically connected to the buffering circuit, receives the speed control voltage signal from the buffering circuit and generates a driving signal according to the speed control voltage signal so as to control the operation of the motor.

Abstract: This invention relates to a process for preparing a patterned layer of aligned carbon nanotubes on a substrate including: applying a photoresist layer to at least a portion of a surface of a substrate capable of supporting nanotube growth, masking a region of said photoresist layer to provide a masked portion and an unmasked portion, subjecting said unmasked portion to electromagnetic radiation of a wavelength and intensity sufficient to transform the unmasked portion while leaving the masked portion substantially untransformed, said transformed portion exhibiting solubility characteristics different to said untransformed portion, developing said photoresist layer by contacting with a solvent for a time and under conditions sufficient to dissolve one of said transformed and untransformed portions of the photoresist, leaving the other portion attached to said substrate, synthesising a layer of aligned carbon nanotubes on regions of said substrate to which said remaining photoresist portion is not attached to p
