The present invention relates to a method for handling the PIN code of the SIM card of a GSM terminal of a remote monitoring device used for remote monitoring of elevators andor escalators andor moving walkways. A ferrule is formed with an optical fiber insertion hole penetrating from the tip end side thereof to the back end side and an opening communicating from the side of the ferrule to the optical fiber insertion hole. At least one conductive surface is coupled to the RFID device. Because conditions for the polycrystalization annealing of the active layer are equal for the pixel section TFT and the driver section TFT, TFTs with the same properties can be obtained. An OPC model suitable for the preliminary mask layout may be selected from the model group based on the analysis data.
