Disclosed is a liquid crystal display device including a liquid crystal layer sandwiched between two substrates; two polarizers each provided on an outer side of respective one of the first and second substrates; and a compensation film provided between the polarizer and the substrate, wherein the retardation of the biaxial film satisfies the following formulae – andor -:1\u2266R0R0\u22661. The relining data generally include variables treated as discrete timefrequency distributions. This regression is referred to as a \u201cmaster\u201d regression. In another embodiment the porous polymer separator sheet has an adherent dissociable lithium compound containing polymer layer on each of its major faces. Each switchable bridge includes at least one resistor with a resistance value that is selected so that a first resistor has a first resistance value WR11 equal to Rmin, a second resistor has a second resistance value WR12 greater than or equal to WR11 and an n-th resistor has an n-th resistance value WR1n greater than or equal to WR1n\u22121. The sleeve type agitator is arranged vertically in a glass melt feed channel in a glass melt feed system for making glass tubes or pipes according to the Vello or down-drawn process.
