Electrical motor driven nail gun

A portable electric nailing gun operating from a power supply. The motor accelerates a flywheel, which at the appropriate energy state is coupled through a mechanism to an anvil acting directly on the nail. The actuation is governed by a control circuit and initiated from a trigger switch. The stored energy delivered from the motor is coupled to the output anvil drives the nail. At least one position of the output anvil is sensed and once the nail is driven, the power is disconnected from the motor. This method uses a direct acting clutch and a harmonic motion nailing mechanism to reduce wear and increase robustness of the nailer. Elastic elements are used to limit stresses during the impact periods. The electrical control circuit and sensors allow precise control and improve safety. The power supply is preferably a rechargeable low impedance battery pack.

Apparatus for controlling a fastener driving tool, with user-adjustable torque limiting control

An improved hand-held fastener driving tool is provided with an adjustable torque limiting control. The tool is portable, and is electrically powered using either a battery pack or a power cord as a power source. The tool drives collated fasteners (e.g., screws) into solid objects. The motor current is measured to determine the amount of torque being applied to a screw by the motor and mechanical drive components. As the screw bottoms out, the motor torque increases to a point where it exceeds the user-adjusted torque limiting control. The motor is automatically turned off at that point, thereby preventing the screw from being stripped.

Battery pack, electronic appliance, and method of detecting remaining amount of battery

A battery pack has a charge and discharge count measuring part (131) configured to measure the number of times of charges and discharges of a secondary battery based on the summed value of the charge current for the secondary battery, and a decay rate output part (132) configured to compute a decay rate that indicates a degree of decay of the secondary battery based on the number of times of charges and discharges measured by the charge and discharge count measuring part (131) and to output it to a device being a discharge load. For example, the charge and discharge count measuring part (131) repeatedly sums the detected values of the charge current to a predetermined threshold, and counts up the number of times of charges and discharges every time when the summed value reaches the threshold. Accordingly, even though charges and discharges are repeated at finer steps in a relatively narrow voltage range, the number of times of charges and discharges can be counted accurately, and the computing accuracy of the decay rate is improved. In the battery pack in which the secondary battery is accommodated, parameters for detecting the remaining amount of the battery are detected more accurately.
