A system is provided for integrating custom policy rules with a policy validation process for validating forms within an organization. The computer system includes a plurality of processors, a plurality of inputoutput devices each capable of issuing interrupts, and an IO bridge interfacing between the IO devices and the processors. At least a part of the surface material is air-permeable, and the surface material is positioned in the inner space. The second blade contacts the surface of the image carrier to level the lubricant supplied to the surface of the image carrier by the lubricant supply roller to a thin layer and to remove the untransferred toner from the surface of the image carrier. In a case that the number of the plurality of mobile terminals to which the transmission signal is to be transmitted is Nv and the number of the plurality of antennas is Nb, the data control circuitry multiplies the transmission signal by a precode matrix.
