[0058] To easily describe the relationship between one object or component and another, as shown in the figure, spatial relative terms such as "below," "below," "lower," "above," and "upper" can be used. It should be understood that, in addition to the orientation shown in the figure, spatial relative terms also include terms indicating the different orientations of the objects when used or manipulated. For example, when the object shown in the figure is flipped, an object described as "below" or "below" of another object can be located "above" of that object. Therefore, the exemplary term "below" can include both "below" and "above" orientations. An object can also be oriented in another direction, thus spatial relative terms can be interpreted according to orientation.
