An inkjet recording apparatus having a recording head unit having nozzle lines driven with multi-phase drive, a moving unit to move the recording head unit in a scanning direction crossing the nozzle lines, a clock generating unit, and a recording head control section. The media source, motion device, and display are all in communication with the controller. When the computer completes the booting process, the first operating system is loaded and executed, the second operating system kernel program memory region is established in a system memory, and the second operating system kernel program is loaded into the second operating system kernel program memory region. The chrominance values can be based on the blue and red difference components from the YUV image format, and the U and V values can be combined using color temperature information. Further, there is provided a centering tongue portion 36b which determines the center in the vertical direction of the connector main body 21 such that it presses an inner peripheral face of the mounting object hole 11 when a connector 20 is inserted into the mounting object hole 11. Animal testing demonstrates that these compounds are useful for treating inflammation, a hallmark disease for CCR2.
