摘要： Provided are an apparatus for controlling a lamp driving, and a light unit. The apparatus comprises a trans-portion, a plurality of lamps, a first cable, and a current attenuator. The trans-portion outputs a first AC power and a second AC power. The plurality of lamps are lighted-on by the first and second AC powers. The first cable and a second cable transfer an output power from the transformer to both ends of the lamps. The current attenuator removes a deviation in currents input to both ends of the lamps.

摘要： An embodiment for low power-consumption RC oscillator is disclosed. A voltage transforming unit transforms a power supply voltage to an internal voltage. A current mirroring unit is coupled to the voltage transforming unit and receives the internal voltage to provide constant two current outputs with different phases. A current charging/discharging unit includes first and second nodes to receive the two constant current outputs of the current mirroring unit, wherein first and second capacitors are coupled to the first and second nodes, respectively. The first and second capacitors are charged by the two constant current outputs. A voltage sensing and outputting unit is coupled to the first and second nodes, senses voltage levels of the first and second nodes and outputs clock signals when one of the sensed voltage levels is greater than a logic threshold. A pulse generating unit generates pulse signals in response to the clock signals. The current charging/discharging unit further includes a connection switch to electrically connect the first and second nodes in response to the pulse signals.

摘要： A protection device of a DC-powered nail gun includes collar mounted to a connection rod on the trigger and the collar has an inner diameter larger than an outer periphery of the connection rod so that when the trigger is not pulled, the collar is positioned to pivot a second switch so that the push member of the shooting unit of the nail gun cannot activate an activation button on the second switch when a new battery pack is installed. By the collar and the pivoted second switch, the nail cannot shoot even if the push member is powered and moved by the new battery pack.

摘要： A nail magazine for alternatively accommodating T-nails or U-nails includes a nail track and a stop block. The nailing track has a bottom notch and a first nail hole upwardly extended from the bottom notch for holding a T-nail. The stop block is positioned in the bottom notch of the nailing track and has a top side, a left side and a right side, which define with a peripheral wall of the bottom notch of the nailing track a second nail hole for holding a U-nail. The stop block further has a top cut groove aligned with the first nail hole such that the T-nail held in the first nail hole is in coincidence with an axis of a driving path that aligns with the second nail hole, thereby enabling the T-nail to be positively and straightly driven into a workpiece.
