Apparatus applies chemicals to condensate water from an air conditioning condensate tray. During data saving, a to-be-saved data file is given to the archive device, and a divisionencryption means carries out divisionencryption, and individual divided files are distributed and saved onto data servers by a network communication means. The grain size ratio of the average crystal grain size of the magnetic body part in the first region to the average crystal grain size of the magnetic body part in the second region is 0. The first switching device is high impedance when the DUT is not being tested. The adaptive forward lighting function may provide adjustment of a beam direction of the at least one forward facing light of the equipped vehicle.
