An internal combustion engine includes a reformer for reforming a fuel air mixture to produce a reformed gas, a crank angle sensor for detecting a rotational speed of the engine, and an ECU. The liquid crystal display device includes a first substrate, and a second substrate opposite to each other, a first alignment film on the second substrate, the first alignment film having a first alignment film groove in a predetermined portion, a first spacer in the first alignment film groove, and a liquid crystal layer between the first substrate and the second substrate. A test clock generator may receive a clock signal generated by the clock generator, and the test clock generator may output a higher frequency test clock signal derived at least in part from the clock signal generated by the clock generator. A hardware shift register is associated with each drive side interface, wherein each bit of the register is connected to an off-chip driver on the interface. By using the partition index to reduce the number of document index sub-partitions searched while executing a search query, the execution of the search query is made more efficient. A first electrically interconnected network extends from the first composition in the first layer to the third composition throughout a thickness of the composite layer, and a second electrically interconnected network extends from the second composition in the second layer to the fourth composition throughout the thickness of the composite layer.
