To prevent a battery pack from being over-discharged even under a state that the battery pack (a secondary battery) is connected to a discharging device that is not connected to an ac input power source for a long time. A charging device 200 has a pair of output lines L1 and L2 and an anode terminal O1 and a cathode terminal O2 of a secondary battery 2 electrically connected between the output lines L1 and L2 to carry out a charging operation. In the charging device 200 including a component circuit part (a resistance 33, a series connecting circuit of resistances 102, 103 and 105, a series connecting circuit of resistances 91 and 92 and an inner circuit part of a shunt regulator 116) electrically connected by traversing a part between the pair of output lines L1 and L2, a switching element 121 is inserted between the component circuit part (the resistance 33 or the like) and one of the pair of output lines L1 and L2. When the charging device 200 is not connected to an input power source 1, the switching element 121 is allowed to be non-conductive to interrupt a discharging path so that the component circuit part does not form the discharging path.

A power tool 1 is connected to a battery pack 5 including an overcurrent detector 533 which detects overcurrent of a battery module 51 and outputs a detection signal, and an overdischarge detector 532 which detects overdischarge of the battery module 51 and outputs a detection signal. The power tool 1 includes a motor 2 which is driven by electric power supplied from the battery pack 5, a trigger switch 31 for setting the power supply from the battery pack 5 to the motor 2 in ON/OFF state, and an FET 410 which sets the power supply to the motor 2 in ON/OFF state on the basis of the detection signal from the overcurrent detector 533 or the overdischarge detector 532.

To improve reliability of a semiconductor device. In a conductive material that electrically couples a Cu pillar electrode and a lead, an alloy part comprised of an alloy of tin and copper is formed inside this conductive material. At this time, the alloy part contacts both the Cu pillar electrode and the lead, and the Cu pillar electrode and the lead are bound through the alloy part. Similarly, also in FIG. 8, it is found that the Cu pillar electrode and the lead are electrically coupled to each other by the alloy part. Thereby, it is possible to improve electric coupling reliability between the Cu pillar electrode and the lead.

An information processing apparatus includes a first generating unit, a second generating unit, and an updating unit. The first generating unit generates a point spread function representing the degree of blurring generated in the input image. The second generating unit generates a plurality of corrected block images obtained by correcting blurring of structure components of plural input block images based on the point spread function. The updating unit executes one or more times an updating process to update the corrected block images, followed by making structure components of the updated corrected block images into new corrected block images.
