An image processing apparatus which makes it possible to automatically defining a processing area in which image processing is to be performed according to the type of image processing, to thereby improve user friendliness. The flat display panel has sustain electrodes and scan electrodes arranged in one direction and data electrodes in a second direction perpendicular to the first direction. When the first edge of the circuit board is inserted into a slot of a connector socket, contact surfaces of the first and second retention bosses contact top surfaces of the connector socket to help immobilize the circuit board with respect to the connector socket. Further, the cooling medium enters into a low temperature probe via a transfer tube, cools a probe coil to 5 to 10K by a heat exchanging portion, further cools a radiation shield to 40 to 60K, and makes a circuit via the countercurrent heat exchanger. The lighting device includes a base portion, a diffuser portion having a wall defining an inner cavity, wherein the wall includes a plurality of colors, the plurality of colors defining a color pattern, and a light source for illuminating the diffuser portion. A parameter modeling component along with a parameterization component and an instantiation component are used to create parameterized example instances and tooling instructions are then invoked to customize a \u201cp-instance\u201d into a real instance reflecting creation of a document or file or other program artifact resulting from actual use of the software application.
