An evaporator includes a refrigerant inlet header section, a refrigerant outlet header section, and a refrigerant circulation path connecting the two header sections. Recording is done to form a gap between predetermined recording units. The liquid product shows increased storage stability with respect to crystallization of the 1-diaminomethyltolutriazole when the polyacrylate polymer is added during the reaction to prepare the 1-Diaminomethyltolutriazole. As a result, probe devices having sharp tips and short cantilevers exhibit fundamental resonant frequencies greater than 700 kHz or more. By such ordering, the search space for all possible CCE ordering and sizes can be reduced to an efficient tree. The extension supports a first attachment in a position separating it from a second attachment in the line of separation.
