    Abstract: A wheel stop is disclosed which is engaged by a wheel of a vehicle in an attempt to be parked in a parking lot, to limit movement of the vehicle. The wheel stop includes a middle extending portion, first and second leg portions, all of which are integrally formed with a metal pipe. The wheel stop further includes first and second anchor plates affixed to the first and second leg portions, respectively, the anchor plates being anchored to the parking lot; an electric cable disposed within the metal pipe; and an electric outlet disposed on an outer surface of the metal pipe, and connected with the electric cable, to thereby allow, when the vehicle parked in the parking lot is an electric car, a power supply cable extending from the electric car to be plugged into the electric outlet.

    Abstract: Phosphor layers are formed on the inner surface of a face plate. An electron source device that emits electrons to excite the phosphor layers is provided on the inner surface of a base plate. The electron source device comprises an alumina substrate that has a number of small through holes. Electron-emitting material is buried in the through holes. A reference electrode is formed on the lower surface of the alumina substrate and contacts the electron-emitting material. A gate electrode is formed on the upper surface of the substrate and insulated from the electron-emitting material. The gate electrode is configured to concentrate an electron field of the electron-emitting material by virtue of an voltage applied between the reference electrode and the gate electrode, thereby to cause the electron-emitting material to emit electrons toward the phosphor layers.
