In the present invention, a product is manufactured in a manufacturing process controlled and tracked using a manufacturing execution system or MES. A determination circuit compares a predetermined comparison target pattern with output patterns of the first and second phase comparison signals corresponding to each bit of a detection data pattern. The system also includes a calculating unit to calculate an intimacy of each of the friend relationships based on the extracted communication information. The broadcast common-synchronization channel has a common chip-sequence signal common to the plurality of remote stations, and a frame-timing signal. Further, the securing grooves maintains slides at a fixed height to improve the scanning quality.
