A method for interfacing with an enterprise resource planning system is provided. This extreme pressure agent comprises a copolymer which comprises an alkyl acrylate represented by general formula and a hydroxyalkyl acrylate represented by general formula as the essential constituent monomers, and is characterized in that the reaction ratio of the component to the component ) is 5050 to 8020 and the copolymer has a weight average molecular weight of 40,000-150,000. The two power conversion circuits are connected in reverse polarity to each other via the two direct-current inductors. In this aspect, the content is seamlessly redirected to the other cloud without requiring any direct network connectivity between the clouds. Thus, it is possible to provide an SOI transistor causing no decrease in the sourcedrain breakdown voltage resulting from substrate floating effects and causing little OFF leakage current because of the activation of the parasitic transistor. The write word request line sets the valid lines for the corresponding entry in each of the two clock domains, while the read word request line resets these valid lines for that entry.
