An endodontic instrument with an elongate shaft and a plurality of inverted frusto-conical sections with radial cutting edge disposed along a working portion of the shaft. Wherever a code sequence is to be inserted, a relocation instruction specifies the location of the code sequence and the code sequence is inserted into the section data at the appropriate point. A first weather forecast section makes a first weather forecast based on the necessary weather information, a communication section transmits the weather information and receives the threshold information, and a weather forecast output section outputs the first weather forecast. In multiphase applications, the low height to diameter ratio of the pancake coils causes the transformer to become quite wide.
