The patterning device includes a chamber, light transmissive plates, and a laser emitter. The chamber has a light transmissive window including a first light transmissive plate through which a laser beam is transmitted and accommodates a thin film laminated substrate.

The laser emitter is outside the chamber and emits the laser beam towards the thin film laminated substrate, through the first light transmissive plate and the second light transmissive plate, to irradiate and remove a portion of the thin film.

Abstract: To acquire information on the refueling position when a vehicle is refueled. A SO2 sensor detects the concentration of sulfur dioxide in the exhaust gas of the internal combustion engine after refueling. Region-by-region concentration information that associates refueling position information with information obtained by averaging sulfur dioxide concentration is transmitted to the data center. As a result, it is possible to accumulate information reflecting the properties of fuel distributed in each area in real time in the data center.
