A downhole electric motor device has a longitudinally extending tubular housing; a stator part deployed within the tubular housing; a stator coil winding looped through the stator part with an end turn having an apex; and a connecting device connecting between at least one of the coil windings and an end of the housing adjacent to an end of the stator part, thereby supporting the coil winding. The voltage pulse is applied to the variable resistance element so that the cumulative pulse applying time is not longer than a specific cumulative pulse applying time, in which the changing rate of the, resistance value is changed from positive to negative with respect to increase of the cumulative pulse applying time in the resistance hysteresis characteristic. The second pump further conducts the sample from the reservoir through a second conduit. When administrating a task associated with an enterprise planning activity, the administration console may break the task into a number of jobs, each job associated with a different slice of the model in accordance with the organizational hierarchy defined by the model. The stop improves contact between the vehicle window surround and the vehicle body while the vehicle is moving, and can be retracted to make it easier to close the door.
