摘要： To provide a universal battery charger with low power consumption during a standby condition and a rush current suppressing capability at the time of commencement of charging, a voltage slightly larger than a battery voltage is produced and applied to the battery. Thereafter, the highest voltage is produced and applied to the battery to charge the same. When the battery is unloaded from the battery charger, the lowest voltage is produced to save power consumption.

摘要： A DC power source unit supplies a DC voltage to a power tool through an adapter when a power switch of the tool is turned ON and also charges a battery pack used as an alternative power source of the tool when the power tool is not operated. In order to prevent a rush current from flowing in a switch interposed between a switching power source circuit and the battery pack when charging the battery pack is commenced, the switch is rendered OFF when the output voltage from the switching power source is greater than the battery voltage. Charging the battery is started upon once lowering the output of the switching power source to a level lower than the battery voltage.

摘要： A DC power source unit supplies a DC voltage to a power tool through an adapter when a power switch of the tool is turned ON and also charges a battery pack used as an alternative power source of the tool when the power tool is not operated. A minimum battery temperature gradient amongst battery temperature gradients ever computed is used to determine whether the battery pack has cooling effect when forcibly cooled by a cooling fan or whether the battery pack has reached a full charge condition. When charging the battery pack is interrupted due to operation of the power tool, computing the battery temperature gradient is halted for some time or determination of the battery pack's full charge condition is not performed for some time in order to prevent the minimum battery temperature from being updated during interruption of charging of the battery pack.

摘要： A miter saw for displaying angle of a cutter blade cutting the workpiece. The miter saw has a base mounting a workpiece thereon, a movable member movably supported to the base, and a cutting unit connected to the movable member for supporting the cutter blade. A positioning portion is associated with the movable member and provides a predetermined nominal position of the movable member with respect to the base. The predetermined nominal position includes a reference position and other positions labeled angle. A detector detects the position of the movable member with respect to the base. A processor sets an angle between the reference position and the predetermined nominal position as a displayed moving amount when the movable member is positioned at the predetermined nominal position. Otherwise, the processor computes the moving amount based on the output signal from the detector.

摘要： To provide inexpensive and economic battery chargers with excellent productivity, a control circuit board for the battery charger is produced so as to be usable in common for both the battery chargers with a cooling device and the battery chargers without a cooling device. In the control circuit board, a cooling device detection circuit is provided for detecting whether or not the cooling device is provided. An average charge current to be applied to a battery pack to be charged is controlled depending on whether or not the cooling device is provided. The average charge current is further controlled depending on the type of the battery pack, i.e., whether it is of a small rated capacity or of a large rated capacity, and on a rate of change in battery temperature at the time of start of charging.

摘要： A status of a battery is detected to determine whether an amount of residual charge is large or not. Detection of the status of the battery is performed on the basis of a change in the voltage level over a preliminary charge time. If the battery is determined to at low charge, then a sleep time is set. The full charge condition of the battery is, for example, detected when a second order differential of the voltage across the battery becomes negative. However, the computation of the second order differential is not performed during the sleep time. Further, to accurately determine the status of the battery, the duration of the preliminary charge time is prolonged if the battery is detected to have been deeply discharged.
摘要翻译：检测电池的状态以确定剩余电量是否大。基于预备充电时间内的电压电平的变化来进行电池的状态的检测。如果电池被确定为低电量，则设置睡眠时间。例如，当电池两端的电压的二阶差分为负时，检测电池的充满电状态。然而，在睡眠时间期间不执行二阶微分的计算。此外，为了准确地确定电池的状态，如果检测到电池被深度地放电，则预充电时间的持续时间延长。

摘要： A power tool includes: a battery cell group including a plurality of secondary battery cells; a motor to which an electric power is supplied from the battery cell group through a switching element and a trigger switch; a current detector detecting a current value flowing in a current path; and a controller configured to receive a detection signal from the current detector and controls on/off operation of the switching element. If the current detector detects that the current value flowing in the battery cell group continuously exceeds a given value for a first time period, the controller conducts one of alarm display and alarm control for allowing an operator to recognize that a high load operation continues. If the current value continuously exceeds the given value for a second time period longer than the first time period, the controller turns off the switching element to interrupt the current path.
