Abstract: An electrically-driven working apparatus in one aspect of an embodiment of the present disclosure comprises: a battery; an abnormality detection unit; a power supply path; a first disconnection unit; a second disconnection unit; and a control unit. The control unit activates the first disconnection unit to disconnect the power supply path if either of an overload or an over discharge of the battery is detected by the abnormality detection unit, and subsequently determines whether discharge from the battery has stopped after activating the first disconnection unit, and activates the second disconnection unit to disconnect the power supply path if discharge from the battery has not stopped.

Abstract: A random number generating device includes a processing request part, a receiving part, a counting part, and a random number generation part. The processing request part makes a request for a predetermined processing to a processing requested object. The receiving part receives a response from the processing requested object in response to the request. The counting part performs a counting operation to increase or decrease a count value with a predetermined cycle, the counting operation being started at least prior to receipt of the response. The random number generation part acquires at least one count value of the counting part at least one predetermined acquisition timing after the receipt of the response is started, and generates a random number by using the at least one count value that is acquired.

Abstract: A battery pack of an electric power tool comprises ten lithium-ion cells. The ten lithium-ion cells are connected in series. Each lithium-ion cell has a diameter equal to or less than 18 millimeters, a length equal to or less than 65 millimeters, and an internal resistance equal to or less than 30 milliohms. Because the battery pack has a high voltage in operation and is therefore able to supply large current, the battery pack is preferably configured incapable of being used in a conventional electric power tool that cannot operate under such a large current.
