    • A method for preventing the camber of a two-layered clad metal sheet having a base layer and a covering layer of different metals which exhibit different amounts of thermal contraction. The method comprises developing a temperature difference .DELTA. T expressed by the following formula between the base layer and the covering layer during a hot levelling, by providing a greater cooling effect before or during levelling to the layer which exhibits the greater thermal contraction than to the layer which exhibits the smaller thermal contraction:.DELTA.T=f (.DELTA..alpha., .alpha., a, To)where,.DELTA..alpha.: the difference in thermal expansion coefficient between both metalsa: the clad ratio (ratio of covering layer thickness to total sheet thickness)To: hot leveller inlet temperature (.degree.C.).alpha.: mean thermal expansion coefficient of both metals.Since the layer which exhibits a greater thermal contraction is forcibly cooled before or during a hot levelling adequately and by a required amount, the clad metal sheet does not exhibit any substantial camber after cooled down to the room temperature.

    • A locking mechanism of a battery pack A is provided with a hook 14 which can be locked to a mounting part B of an object equipment such as an electric tool in a state slid with respect to the mounting part, and operation parts 16 for releasing the lock which are linked to the hook 14, on a case which contains a battery. The hook 14 is urged to move upward by an elastic body in a direction of being locked to the mounting part B.The operation parts 16 are arranged in both side parts of the case within such a range that they can be grasped with a single hand from both sides of a backward end in the sliding direction of the case. When the operation parts 16 are operated from the both sides, the lock between the hook 14 and the mounting part B is released against the urge by the elastic body.
