Abstract: A battery pack for a power tool of self-contained over-charge protection is proposed. The battery pack includes a battery stack composed of a plurality of series connected secondary cells, and a charge terminal connected through a charge current path to the battery stack for flowing a charge current from a charger. The battery pack includes an interrupter inserted in the charge current path, and an over-charge detector which detects a cell voltage across each of the secondary cells and actuates the interrupter to open the charge current path when any one of the cell voltages becomes higher than a predetermined threshold (VTH3).

Abstract: Disclosed is an electrostatic atomizer, which comprises a high-voltage applying section adapted to apply a high voltage between an atomizing electrode and a counter electrode so as to electrostatically atomize water supplied onto the atomizing electrode, wherein the high-voltage applying section is operable to set an absolute value of a voltage to be applied to the atomizing electrode smaller than an absolute value of a voltage to be applied to the counter electrode. This allows a physical object, such as an article stored in a mist-receiving space or an inner wall of a structural member defining the mist-receiving space to become less likely to be electrostatically charged, and makes it possible to avoid causing a problem about discomfort due to discharge of static charges when a user touches the physical object.
