A method for actuating a system on chip includes the following steps. The first arm has an inner wall, a first recess in the inner wall, and an inclined surface that extends toward the first recess. Further, by electroplating portions provided between the oxidation layers with copper or filling conductive paste between the oxidation layers using a screen, a package substrate having a fine circuit pattern is achieved. In further embodiments, discarding at least one log entry includes discarding at least one log entry that is at least one of opposed by or overruled by at least one subsequent log entry. The Benzopyranone Compounds have the formula:or a pharmaceutically acceptable salt thereof, wherein R1 is halogen, trifluoromethyl or C1-6 alkyl.
