A semiconductor circuit includes a voltage regulator and a buffer transistor. The voltage regulator converts an input voltage input to an input terminal thereof into an output voltage output to an output terminal thereof. The buffer transistor is an n-channel depletion-mode metal-oxide semiconductor field effect transistor, disposed between the power supply terminal and the voltage regulator with a gate terminal thereof connected to the power supply terminal, a drain terminal thereof connected to the power supply terminal, and a source terminal thereof connected to the input terminal of the voltage regulator.

A charging device for use in charging plural types of secondary batteries includes a power source unit for supplying a charging current to an object secondary battery, a battery type signal receiving unit for receiving a battery type signal, a battery temperature signal receiving unit for receiving a battery temperature signal, a blowing unit for blowing an air to the secondary battery, a storage unit for storing reference judging temperatures for determination of charging-incongruent temperatures of the plural types of secondary batteries, in a matching relationship with the types of the secondary batteries, and a control unit. The control unit allows the blowing unit to perform a blowing operation, if the temperature of the secondary battery exceeds a reference judging temperature, and to stop the blowing operation, if otherwise.

Charging device and rechargeable power tool set

An electrical apparatus includes an electrical apparatus main body and a battery pack. The electrical apparatus main body has a load, a manipulation switch, a power receiving electrode, a main body control unit for controlling the electric power supplied from the power receiving electrode in response to a manipulation of the manipulation switch, a signal generation unit for generating an on-manipulation signal if the manipulation switch is switched on, and a main body signal electrode for outputting the on-manipulation signal. The battery pack has a battery, a power supplying electrode, a battery control unit for controlling the electric power supplied from the battery to the power supplying electrode, a battery signal electrode for receiving the on-manipulation signal, and a power supplying unit for starting a power supply from the battery to the battery control unit when the battery signal electrode receives the on-manipulation signal.

Electrical apparatus

An electric tool having the capability of achieving a high working efficiency is provided. This tool comprises an output shaft rotated by reversible motor, a rotational-direction switch for switching a rotational direction of the output shaft in either forward or reverse direction, first memory for storing a plurality of operation modes of the output shaft with respect to one of the forward and reverse directions, operation-mode switch for selecting one from the operation modes, second memory for temporarily storing an operation mode selected by the operation-mode switch in a use of the electric tool at the one of the forward and reverse directions; and a controller for automatically setting the electric tool in the operation mode stored in the second memory in the next use of the electric tool at the one of the forward and reverse directions.
