A brushless permanent magnet motor has a rotor constructed of spaced ferromagnetic backirons and a circumferential array of alternating polarity magnetic poles that drive magnetic flux back and forth across an armature air gap between the backirons. More specifically, the present invention relates to a diagnostic system for forming at least one image of an object having enhanced contrast. The antenna omits a wave field whose strength is proportional to the current delivered to the antenna and this is monitored. In addition, the first user selectively specifies which historical purchase information may be viewed by the second customer. The code defines a kind of function which figures out an injection speed command data or a holding pressure command data corresponding to each stroke position or time. The rechargeable battery can be provided in a module equipped with a receptacle capable of receiving a standard plug designed for line voltage, and in this case, the lamp requires no modification other than the replacement of the standard bulb by the low voltage LED bulb.
