A microsensor for detecting corrosive media acting on a bulk metallic material when mounted in situ adjacent a location in the bulk metallic material. When Ls is longer than L, the pre-registration roller and the registration roller are controlled so that the jammed sheet is conveyed toward the upstream until the rear end of the sheet passes through an upstream end of the area A1. The intermediary verifies that the seller is authorized to sell the regulated goods using information about the seller maintained by the intermediary. Thus, even transparent conductive layer is not etched clearly and forming residuals, the residuals will not cause short circuits between the metal lines and transparent pixel electrodes. The second vehicle is then queried for authorization to transmit the information and, if given, the information is then transmitted to the second vehicle via the communications link.
