Abstract: A battery pack (60), which is rechargeable by a charger (600), includes one or more battery cells (60), a control part (620), a communication part (620, 400, 15), and a switching-control part (620). The control part is configured to be switchable to any of a plurality of operation states, including a controlled-operation state and a low-power operation state. The switching-control part: compares a communication-stop time (Ta1) to a state-switching determination value (Tth1); does not switch the operation state of the control part if the communication-stop time is less than or equal to the state-switching determination value; and does switch the operation state of the control part to the low-power operation state if the communication-stop time exceeds the state-switching determination value, whereby power consumption of the control part can be reduced upon completion, e.g., of a charging operation.

Abstract: A striking tool restricting movement of an intermediate member toward a striker reliably prevents no-load strokes. A hammer drill includes a cylindrical tool holder holding a tip tool, a motor, a piston that reciprocate with rotation from the motor, a striker that reciprocate in cooperation with the piston, an intermediate member reciprocably accommodated in the tool holder between the striker and the tip tool and in contact with a rear end of the tip tool at a normal strike to indirectly transmit a strike from the striker to the tip tool, and at least two ring members that move in a front-rear direction accommodated in the tool holder at a front of the intermediate member between the tool holder and the intermediate member. At least one ring member is made of metal.

Abstract: A work tool includes a spindle, a clamp shaft and at least one biasing part. The spindle is configured to be reciprocally rotated within a specified angle range around a driving axis. The spindle has a first inclined face inclined in a direction crossing the driving axis. The clamp shaft includes a shaft part and a head part. The shaft part is configured to be coaxially inserted into the spindle. The head part is formed on a lower end portion of the shaft part and configured to clamp the tool accessory in cooperation with the spindle while a second inclined face of the tool accessory is pressed against the first inclined face. The at least one biasing part is provided in the spindle and configured to always bias the tool accessory downward while the tool accessory is clamped by the head part and the spindle.

Abstract: A dust collecting system includes a power tool configured to perform processing operation on a workpiece by driving a tool accessory and a dust collector configured to collect dust generated by the processing operation. The power tool includes a first motor, a driving mechanism, a body housing, a first detecting device, an operation member and a second detecting device. The first detecting device is configured to detect an operation of pressing the tool accessory against the workpiece. The operation member is configured to be externally operated by a user. The second detecting device is configured to detect an operation of the operation member. The dust collector includes a second motor and a fan. The dust collecting system includes a first control device configured to control driving of the second motor based on detection results of the first detecting device and the second detecting device.

Abstract: In one aspect of the present disclosure, a laser marker includes a supporter, a movable portion, at least one laser optical source, a tilt sensor, a first actuator, and a controller. The movable portion is tiltably supported by the supporter. The tilt sensor is provided to the movable portion, detects a first tilt of the movable portion, and outputs a first detection value that indicates the first tilt. The first actuator changes a tilt of the movable portion with respect to the supporter. The controller controls the first actuator such that a center value of a first series of detection values and a reference value coincide with each other.

Abstract: A connector in one aspect of the present disclosure includes a first housing and a second housing. The first housing includes a first terminal, an insertion portion, and a displacement portion. The displacement portion is provided at an outer periphery of the insertion portion and includes a moving member. The second housing includes a second terminal and a tubular portion. The tubular portion allows insertion therein of the insertion portion to a locking position while the moving member is elastically displaced to an inner position. The tubular portion also includes a locking portion that locks with the moving member to thereby inhibit pullout of the insertion portion from the tubular portion.

Abstract: A chainsaw includes a handle with a handgrip; an electric motor for endlessly moving a saw chain; a control unit for controlling rotation of the motor; and a main power switch switchable between an ON state and an OFF state. The handgrip is provided with a gripping detection device for detecting whether the handgrip is gripped by the worker, and the chainsaw is configured to, when the control unit is manipulated to deactivate the electric motor in a state in which the gripping detection device detects that the handgrip is gripped, maintain the main power switch in the ON state, and to, when the control unit is manipulated to deactivate the electric motor in a state in which the gripping detection device detects that the handgrip is not gripped, switch the main power switch to the OFF state.
