An array substrate is provided for an in-plane switching mode liquid crystal display device. A touch panel includes a pair of transparent substrates opposed to and away from each other and connection terminals provided on at least one of opposed surfaces of the pair of transparent substrates. The information recording medium is formed based on a recordable recording medium. The heat accumulator alternately accumulates thermal energy from the transmission oil and delivers previously stored thermal energy to the transmission oil. The BLTE application of differentially sized flat blades solves the problem of internal combustion and multi-stage operation for this new category of engine.
