摘要： A microcomputer performs a total of 100 sampling actions during a 1 sec sampling period for obtaining a plurality of battery voltage data V. In each sampling period, a minimum value .upsilon.min and a maximum value .upsilon.max are stored in a RAM 53. A peak value VMAX, used for detecting a peak battery voltage in the charging operation, is renewed by a largest data among the sampled minimum values .upsilon.min. A differenc .DELTA.V between the peak value VMAX and the maximum value .upsilon.max is calculated the end of each sampling period. And, when the calculated difference .DELTA.V exceeds a predetermined value, a judgement is made that the battery is fully charged.

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.
