Abstract: A water pump for pumping ice water is provided. The pump includes a motor assembly, a cover, and a tube. The motor assembly includes water pumping blades rotatably set at one end of the motor assembly. The motor assembly includes a water-resistant housing that is set outside and partially encloses the motor assembly. The cover is attached to an end of the water-resistant housing to enclose the motor assembly. The tube extends through the cover to communicate between inside and outside of the cover. Thus, when the pump is positioned in a tank containing ice water, air is allowed to freely flow through the tube between inside and outside of the cover to balance pressures between inside and outside of the pump so as to prevent cracking caused by thermal expansion and contraction from occurring in connection portions of the pump.

Abstract: A method for driving an organic light emitting display (OLED) panel having a plurality of organic light emitting diodes is provided. The organic light emitting diodes are coupled to a plurality of segment lines and a plurality of common lines in a matrix structure. The organic light emitting diodes coupled to the same common lines are divided into a plurality of groups according to colors of the OLED panel. Driving currents are provided to the organic light emitting diodes of the groups according to a plurality of pulse width modulation (PWM) manners. The PWM manners generate waveforms having pulse width corresponding to grayscale in a period, wherein each PWM manner corresponds to different colors of the OLED panel.

Abstract: A guide mechanism and the optical drive utilizing the same. The guide mechanism includes a guiding base, a first axial fixing member, a driver, and a rotary structure. The guiding base comprises a first opening and a second opening. The first axial fixing member is disposed at a side of the guiding base. The driver, disposed at an opposite side of the guiding base, comprises an opening and a second axial fixing member. The rotary structure is fixed between the first axial fixing member and the second axial fixing member, comprising a spindle and a magnetic structure. The spindle comprises an operating region and a connecting portion having a maximum outer diameter smaller than a minimum outer diameter of the operating region. The magnetic structure is attached to the connecting portion and disposed in the opening.

Abstract: A bearing bracket including a metal base and a bushing is provided. The metal base has an opening at its central portion. The bushing of the bearing bracket is made of plastic. The bushing encloses an axial portion or/and a radial portion of the metal base by injection molding. Furthermore, the bearing bracket further includes an anti-vibration member disposed on at least one side surface of the metal base.

Abstract: A frame-varying addressing method of a color sequential liquid crystal display is disclosed for display of successive frames. Each of the frames is composed of three subframes, and each of the subframes is composed of a plurality of scan lines. According to the frame-varying addressing method of the invention, the addressing sequence of scan lines for display of any frame or subframe is arranged in the same direction as those for display of its adjacent frames or subframes, and is selected to be different from those for display of its adjacent frames or subframes. Further, the addressing sequence for the frame (subframe) and its adjacent frames (subframes) can be periodically or randomly selected, so as to effectively balance or greatly eliminate the spatial intensity variations due to inconsistent response times at different portions of the panel.

Abstract: A fan includes an impeller and a motor. The motor includes a rotor structure and a bearing structure. The motor is used to drive the impeller and the rotor structure has a shaft. The shaft is connected to the impeller. The bearing structure includes an oil-retaining bearing, a base and a sleeve. The oil-retaining bearing is used to dispose the shaft and the base is used to support the oil-retaining bearing. The sleeve includes at least one resisting part and a circular sidewall. The circular sidewall is covered the outside of the oil-retaining bearing. The resisting part is disposed on the top surface of the circular sidewall and extended to the center of the oil-retaining bearing.

Abstract: The non-biasing guiding mechanism related to CD-R drives is used to drive a data access device to move along a particular direction and to access the data on a CD. The shaft of the non-biasing guiding mechanism is fixed by an axis-fixing member. The axis-fixing member has ring parts on the opposite ends and a receiver integrally formed with the ring part in a concentric way. The ring part is coiled by a coil and sets inside the drive, and the hole is used for positioning the shaft and sets outside the drive. Therefore, the biasing problem of the shaft can be solved by using the axis-fixing member.
