A piezoelectric element is mounted to a clinch lever for detecting stress-strain generated therein when cutting and clinching leads of an electronic component that has been inserted in corresponding holes formed in a circuit board substrate. In a first embodiment, the first apparatus includes a momentary microswitch, a lever that closes the microswitch when contacted by the basketball, and a timer that activates when the momentary switch is closed. The concentration of the catalyst metal in the semiconductor film and the location of the region to be added with the catalyst metal are so selected in order that a desired crystallinity and a desired crystal structure such as a vertical crystal growth or lateral crystal growth can be obtained. Next, the primary colors of the destination device are examined to determine whether any of these have changes. First metal suicides are formed respectively on the top surfaces of the second transistor’s gate, source and drain. An amount of intake air in accordance with the required load is fed into a combustion chamber by controlling the closing timing of the intake valve, while a pressure, temperature or density in the combustion chamber at the end of a compression stroke is maintained substantially constant regardless of the engine load by controlling the mechanical compression ratio.
