A GUI part selector 13, on the basis of background information received from a question controller 11 and GUI information retrieved from a GUI storage 14, generates backgroundGUI-related information, and generates an output determination table on the basis of the condition of the respondent as determined by a user determinator 15. The antenna assembly includes a battery cover including a metal material, a short-range wireless communication module electrically connected to the battery cover, and a main antenna electrically connected to the short-range communication module. Due to the non-magnetic collar, the tool can withstand the extreme conditions in the borehole environment while the borehole is being drilled. A controller includes motor drive mode determination means and control means. The assembly interacts such that the lead screw nut rotates in one rotational direction when a force is applied to the lead screw in the axial direction. The adhesive member adheres a bottom of the liquid crystal panel to the flexible film.
