A gate wire including a gate line and a gate electrode is formed on a substrate and a gate insulating layer is formed on the substrate. The prototype is analyzed by correlating phase parameters generated from the prototype with phase parameters generated from a reference prototype in multiple frequency bands. Thus, the nonvolatile memory section can hold the logic state even while the supply of power is stopped. The set of driving gears is disposed on the top cover. Alternatively, the first tradeable object and the second tradeable object may be the same, but the indications of quantity may be provided from different sources, such as different exchanges.
