摘要： A lockable rotary cutting mat includes a base plate and a rotary plate. The central bottom portion of the rotary plate is assembled on the center of the base plate through a rotary connector. The rotary plate includes a cutting surface and a periphery. The periphery is formed with concave edge portions, and a locking component is provided at the corresponding position between the base plate and the rotary plate periphery. The locking component includes a moving base, a controller and a locking edge portion. The controller can be pushed along a movement guiding axis on the moving base. The locking edge portion is connected to, and can be driven by the controller to have locked and released positions. When the locking edge portion is at the locked position, it is aligned to, and is engaged with the corresponding concave edge portion, so that the rotary plate is fixed.

摘要： A power factor correction apparatus with an embedded direct-current to direct-current (DC-DC) converter is provided. The apparatus includes a power factor controller, a high-voltage adapter and a low-voltage adapter. The power factor controller, which receives an AC power source, includes a transformer. The secondary side of the transformer includes a first sub-coil and a second sub-coil for outputting a first power source and a second power source respectively. The high-voltage adapter converts the first power source into a high DC power source. The low-voltage adapter converts the second power source into a first DC power source. The power factor controller corrects the power factor of the power factor correction apparatus according to the first DC power source.
