Abstract: A power tool includes a motor, an output shaft, a chip-on-board light emitting diode, and a light cover. The output shaft is rotated by a rotational force of the motor. The chip-on-board light emitting diode is disposed around the output shaft. The chip-on-board light emitting diode includes: a substrate including a circular ring portion; and an LED chip disposed on a front surface of the circular ring portion. The light cover is fixed to the substrate. The light cover includes: an outer cylindrical portion disposed radially outside with respect to the circular ring portion; and a light transmission portion through which light emitted from the LED chip passes. An opening is provided in a lower portion of the outer cylindrical portion.

Abstract: A battery-powered system includes a battery pack (10; 71; 81) connected to an electrical equipment (30; 50; 76; 86). The battery pack includes a first positive electrode terminal (11), a first negative electrode terminal (12), a first communication terminal (13), a first data input circuit (23), and a first limiting circuit (D11; D72; D82) that limits a flow of electric current in a direction from the first negative electrode terminal to the first communication terminal via the first data input circuit. The connected equipment includes a second positive electrode terminal (31; 51), a second negative electrode terminal (32; 52), a second communication terminal (33; 53), a second data input circuit (43; 63; 77; 87), and a second limiting circuit (D31; D51; D77; D87) that limits a flow of electric current in a direction from the second negative electrode terminal to the second communication terminal via the second data input circuit.

Abstract: An electric power tool in one aspect of the present disclosure includes a motor, an impact mechanism, an impact detector, and a control circuit. The control circuit controls a motor current based on a drive duty ratio in a first driving term. The first driving term corresponds to a time period from when the motor is started until impact is detect. The drive duty ratio corresponds to a sum of a basic duty ratio and a proportional duty ratio. The control circuit controls the motor current so that an actual rotational speed of the motor is consistent with a target rotational speed after elapse of the first driving term.

Abstract: A blower may include an airflow pipe disposed between an inlet and an outlet, an axial flow fan including a hub and a plurality of blades, a drive shaft, an electric motor, a motor housing, a diffuser cone, a first vent defined on the diffuser cone, and a second vent defined between the hub and the motor housing. An airflow path in which air flows from the inlet to the outlet is defined in the airflow pipe. A circulation path in which the air flows from the first vent to the second vent is defined in the airflow pipe. When a circumferential end of the second vent on the inlet side is a first end and a circumferential end of the second vent on the outlet side is a second end, an outer diameter of the first end is larger than an outer diameter of the second end.
