Novel compounds having a fused bicyclic heteroaromatic ring system substituted with a heteroaryl five-membered ring are disclosed. The isolate has a molecular weight at least about 3000 Daltons as determined by molecular weight cut-off filtration. Then, a threshold value is determined on the basis of the amount of resources requested. The anchor sleeve is moveable between an axially elongated configuration and an axially shortened configuration and is biased toward the axially shortened configuration by a force exerted by the elastic portion of the tubular member. Transmission cables are drawn out from the short sides of the respective liquid crystal panels, and a cooling fan is disposed such that the direction of cooling air is approximately parallel with the long sides of the liquid crystal panels.
