Abstract: According to one implementation, a drilling machine includes at least one drilling structure, a travelling machine, a reader and a controlling device such as a controlling circuit. The at least one drilling structure drills an object to be drilled. The travelling machine positions the at least one drilling structure in a travelling direction of the travelling machine by travelling in a direction different from a drilling direction. The reader reads information recorded on at least one integrated circuit tag attached to at least one drilling plate attached to the object to be drilled. The controlling device controls the travelling machine based on the information read by the reader.

Abstract: According to one implementation, a drilling machine includes a drilling structure and a travelling machine. The drilling structure drills an object to be drilled composed of at least one structural object on a platy part. The travelling machine positions the drilling structure in a travelling direction of the travelling machine by travelling in a longitudinal direction of the at least one structural object using the at least one structural object as a guide.

Abstract: An enameled wire capable of improving withstand lifetime with respect to the application of surge voltage of an inverter and thermal degradation thereof while restricting an amount of an inorganic filler material is provided. The enameled wire includes an electrically conductive wire (11) and a coating (12) formed of a high molecular compound uniformly mixed with an inorganic filler material in the form of fine flat particles provided around the electrically conductive wire (11). The enameled wire may include an electrically conductive wire (21), a coating (23) formed of a polyester imide resin solution mixed with an inorganic filler material in the form of fine flat particles and provided on the conductive wire and a coating (24) formed of polyamide imide and provided on the coating (23).

Abstract: An insulated coil for electric rotating machinery, according to the present invention is manufactured based on a method of manufacturing the insulated coil for an electric rotating machinery, which includes the steps of taping a mica tape on a coil conductor to mold an insulating layer, impregnating the coil with resin under vacuum and pressure condition, attaching a molding jig on the coil impregnated with the resin, and then heating the resin with which the coil is impregnated, to cure the resin, thus manufacturing the insulated coil. The mica tape taping step, a heat-shrinkable tape taping step, the impregnating step under vacuum and pressure, the resin heating/curing step utilizing a liquid heating compound and a molding jig-disassembling/finishing step are carried out to manufacture the insulated coil.
