A method and apparatus is described for generating a test case for an application or system modelled using a Stochastic Automata Network model. A driving arm is located at one side within a mount corresponding to staple pushing pieces of the staple slot fixing piece. Image data positioned in the predicted scrolling direction is pre-read from an external storage device. The user-manipulatable control is further movable to move the piston relative to the chamber along the axis to selectively dispense the selected metered quantity of fluid. The stretched resin film of the present invention is resistant to becoming waved when offset-printed with widely-used, quick-drying offset printing inks, and thus has excellent printing properties. The fuel cell has an operating temperature of 100\u2013200\xb0 C.
