The present invention provides methods for extracting similar expression patterns and related biopolymers considering natures that are characteristic of expression data of, for example, genes. The chamfering portion includes a first chamfering portion for allowing the angle shift of the joint, and second chamfering portions which are provided adjacent to both peripheral sides of the first chamfering portion and are inclined in the direction different from the first chamfering portion. The control unit associates a first connection threshold or a second connection threshold that is larger than the first connection threshold with the access point on the basis of the connection time. The total flow rate can also be varied at the optimum relative proportion in order to determine the maximum overall flow rate at which completion of the reactions still occurs. Whenever caller ID information includes a native language name matching the user’s selected languages, the native language name will be displayed on the caller ID device. Then the whole ball structure is heated.
