An electronic device including a display supported by a substrate is described. The discharge space has a filling which comprises mercury, argon, and halides of tin and indium, to which filling an alkali metal halide is added, the alkali metal being potassium, rubidium, or cesium, and the halide being chlorine, bromine, or iodine. The first and second documents may be stored at an intermediary transaction server along with the routines, which may be precompiled in a dynamically linked library. A timer starts to count based on permission of the entrance person authentication section and sets an arrival time value when the arrival detection section detects the elevator arriving at the hall. The actuator position is lockable so that the above 2 modes are possible. A magnetic coupler assembly transfers movement of the float to an indicator.
