In a semiconductor wafer including a plurality of element forming regions formed on a front surface of a semiconductor substrate, a scribe line groove is formed along a periphery of the each of the element forming regions, and stoppers are located at an intersection of the scribe line groove, so as to block the scribe line groove. Therefore, the transition, whose periodic movement is also suppressed, cannot communicate with a suction-side compression shock, preventing the compression shock from augmenting the natural vibrations of the blade occurring under certain flight conditions. The optimization server is configured to receive response data that corresponds to the request data from a content server, to adapt the response data based on the identification data, and to transmit the adapted response data to the mobile device. By controlling the ratio, it is possible to stably discharge from the container storing these two compositions separately predetermined amounts of these two compositions which will otherwise cause a time-dependent change if they are pre-mixed thereby failing to attain the purpose of their addition. A magnetic field generator establishes a magnetic field within the conduit a plurality of electrodes located within the magnetic field and an electric field generator establishes an electric field within the conduit.
