摘要： 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.

摘要： A starting device for feeding a quantity of fuel from the fixed-quantity fuel chamber to an intake passage during start-up having a manually operated primary pump for suctioning/pumping fuel and arranged on a fuel introduction path connected along a fuel-feeding path; and a fixed-quantity fuel chamber for temporarily storing fuel delivered from the primary pump. An internal wall of the fixed-quantity fuel chamber undergoes elastic displacement, allowing its internal capacity to expand/shrink within a predetermined range; the fixed-quantity fuel chamber is connected to a fuel delivery path that communicates with the intake passage side and has a manually operated open/close valve; the valve is opened in a state in which, due to the primary pump being operated, the fixed-quantity fuel chamber is filled with a predetermined quantity of fuel while enlarging its internal capacity, whereby it shrinks due to an elastic contraction force and the fuel.
