    摘要： A first and a second signal line respectively supplying a first potential and a second potential to one end of a capacitive load, a waveform output circuit whose input terminal is connected to a supply line supplying a third potential, whose output terminal is connected to the first or the second signal line, and whose control terminal is connected to a waveform generating circuit, and a reactive current preventing switch connected between the control terminal and the output terminal or the input terminal of the waveform output circuit are provided. During a period when a reactive current is prevented from flowing, the reactive current preventing switch is bought into conduction to make a potential difference between the control terminal and the output terminal of the waveform output circuit smaller so that the waveform output circuit cannot be operated, which prevents the reactive current from flowing, leading to an improvement in the reliability of a driving circuit.

    摘要： An air purifier includes a main body defining an air passage therein to allow sucked air to pass therethrough prior to being discharged, and a first filter installed in the main body to be switched between a closed state and an open state. The first filter removes contaminants from the sucked air in the closed state, and allows the sucked air to pass through the air passage in the open state. The air purifier may include a main body to suck and discharge air, with a bypass passage formed in the main body so that the bypass passage is opened or closed by a door, and a first filter installed in the main body. The sucked air passes through the first filter prior to being discharged when the door is closed, and passes through the bypass passage prior to being discharged when the door is opened.

    摘要： A driving circuit of a plasma display panel is provided in which a display cell including a first electrode and a second electrode is selected to light up, for applying a first voltage Vs1 to the first electrode and a second voltage Vs2 to the second electrode adjacent to the first electrode to cause a sustain discharge between the first and second electrodes. The driving circuit generates a sustain discharge voltage such that, during the sustain discharge between the first and second electrodes, an applied voltage Vc to a third electrode adjacent to the first electrode opposite to the second electrode falls within a range Vs2≦Vc
