Sound signal is received which contains sound characteristics to be represented in musical notation. The dimensions and coordinates of a single three dimensional rectilinear volume within a single region of interest are automatically identified. The at least one protrusion is disposed inside a cooling fluid manifold to reduce the flow amount of the cooling fluid which flows in and out between the separating plates through the cooling fluid manifold. The fourth electrically conductive layer includes a pixel electrode in which a slit facing the common electrode is formed, and a third pad portion which is put in contact with the second pad portion. In addition, its data base memory can also store the 2D sprite, thereby, it not only can speed up the drafting speed of the 3D graphics, but also can achieve the object of integrating the multimedia apparatuses and simplifying the design.
