Abstract: PURPOSE:To obtain electrode train of infinitesimal interval in a charge coupled device by providing a resist pattern having eaves, on a conductivity layer becoming electrodes when forming the electrodes of the charge coupled device and exposing and etching the conductivity layer under the eaves when coating metallic thin film on the entire surface thereof. CONSTITUTION:A gate SiO2 film 2 is coated on a silicon substrate 1, a polycrystalline silicon conductivity layer 10 is vapor grown thereon, and a positive resist film  11 is coated thereon. Then, light is exposed on the film 11 in sufficient exposure  time and illumination thereof by using a photomask having a minimum pattern  width formed possibly, the film 11 is then developed to thereby form a resist pattern 11' having a pattern width of approx. 3mum and eaves 12 of approx. 2,000Angstrom  is  formed at the periphery thereof. When an aluminum thin layer 13 is then coated on  the entire surface, the pattern 11' is separated from the layer 10 so that the layer is not coated underneath the defects 12. Accordingly, it is plasma etched to thereby remove the eaves portion of the layer 10 to thus retain the layer 10 as electrode train but to remove the pattern 11'.

Into said circuit 3, the detection starting-angle information is input from a detection starting-angle instruction appratus 13. The first and the second physical amounts related to the combustion vibration energy in case of non-knock/knock are obtained from the vibration information. As for these physical amounts, the rate of physical amounts is obtained by a calculation part 5, comparator 6, and a comparison standard-value generator 7, and a correction amount is calculated from a correction-amount calculator 8. According to the result of the calculation, the starting time in the measurement division for the first physical amount is properly set by an ignition-timing controller 9, and an ignitor 12 is driven.
