An electrochemical deposition method in which the structure of a substance to be deposited on the surface of a working electrode is determined, an electrochemical deposition apparatus, and a microstructure are provided. Endorsement data is transmitted to an RFID tag of a check transported along the check transport path from the upstream end to the downstream end. The cam member has a cam formed with a cam slope on which the support part of the first roller is pressed by reaction torque from the second roller that is caused by transmission torque applied from the first roller. The measurements of two receivers are related to a common time moment by extrapolating measurement data that has arrived through the connection link with a delay. In some cases, the hydrocarbon compound produced through the non-oxidation reaction includes a hydrocarbon aerosol form as the hydrocarbon compound at least as it is produced or cools. Within the air bag, a partition is provided which has a blocking effect for the gas flow emerging from the gas generator, and a main through-flow opening is formed on the partition.
