The object of the present invention is to form the fine structure on a cathode surface homogeneously and reproducibly to realize the increased emission current value and stability with a simple process in the electron emission element forming process. Guide wires are located along the earth’s surface above the prescribed borehole path and the known electromagnetic field produced by current in the guide wires are detected by the sensors. Condition resolution circuitry 24 responds to the condition resolution micro-operation instruction to determine if the condition prediction is incorrect. The polarity directions of the two magnets are reversed and the same polarity is arranged oppositely on the axis. When the brim curl is in the flare configuration, the brim curl arcuately and convexly extends away from the cup opening to form a brim flare. The photographic stitching device allows a photographer to capture a matrix of precisely overlapping photographs that can later be electronically stitched together to create a higher resolution composite image, a panoramic image, a vista, a stereoscopic image, a 3-D image, an artistic rendering, or similar custom and unique photographic products.
