A vehicle incorporates a storage area with a dynamic floor section. The lower metal layer has a plurality of millichannels configured to deliver a coolant for cooling the power electronics, wherein the millichannels are formed on the lower metal layer prior to attachment to the lower surface of the middle ceramic layer. A spray bar includes a plurality of supply orifices that direct lubricating fluid to the first and second bearings via at least the first and second conduits. A first switch connects V1 to an output terminal when the first FET is driven on, and a second switch connects V2 to the output terminal when the second FET is driven on. The address electrode is arranged a predetermined distance apart from the discharge electrodes in a direction where the substrates are arranged, and defines each of the discharge spaces in cooperation with the discharge electrodes. The base generating agent of the invention is represented by the following formula :, X represents a hydrogen atom, a substituted alkyl group or an unsubstituted alkyl group; Y represents a substituted or unsubstituted alkylene chain; and n represents an integer of from 1 to 4.
