A semiconductor device includes a plurality of parallel conductive lines that are spaced apart from one another in a first direction and extend in a second direction transverse to the first direction. The present invention therefore provides a system for ensuring the presence in a hydratable cementitious composition a sufficient air volume and sufficient air void fineness and consistency. A difference value is then determined in the perceptually linear color space, wherein the difference value is determined by applying a difference model to the device-dependent color value, and wherein the difference model models deviation of the matrix model from actual measurements of the display device. The acquired resonance data provides maybe used to measure the ratio of the spectrally distinct species in exchange. Next, the system intersects X with the initial interval X to produce a new interval X, wherein the new interval X contains all solutions of the equation 0 within the initial interval X, and wherein the size of the new interval X is less than or equal to the size of the initial interval X. The urging member is formed of a resin or rubber material having elasticity; and when the valve member is in the first state, the urging member is compressed in a direction of the path.
