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： A charging circuit generates a charging current from an ac supply which is supplied to a secondary battery in a battery package through first terminals. A second terminal receives a temperature detection signal from a thermistor on the secondary battery. A value of the temperature detection signal is sampled every predetermined interval. A memory stores the sampled value. A difference between the sampled value and the value from the memory is obtained, as well as the temperature decrease value between the sampled value and the value stored, when it applies. An error signal is generated when the difference is higher than a predetermined value and the operator is alarmed and informed of the error. The difference may be obtained between the sampled value and the value one-cycle-previously-sampled value from the memory, between the sampled value and a minimum of the sampled values, or between the sampled value and a charging start value of the sampled value. The thermistor is supplied with a supply voltage through a switch and an error condition caused by leakage of the electrolyte from the battery is detected when the voltage at the second terminal is higher than the predetermined value, the charging current generation circuit is controlled to stop generating the charging current.
