An alignment method is used in implementation of electric characteristic inspection of an object to be inspected via electric contact between the object disposed on a movable mounting table and probes. A controlled resistance modeling the VTM effective series input resistance is connected across the interface terminal. The raw gas input pipe path extends from the raw gas supply port through an automatic pressure controller to the ozone generator. Five selectively engageable clutch mechanisms are interconnectable between members of the planetary gearsets, the input shaft, and the output shaft. The thermostat would be provided with an operating thermostat to keep the diesel fuel at the proper temperature, as well as an over-limit termination device for safety purposes.
