More specifically, the depolymerization system is controlled to suppress an effective concentration (x+100y wt. %) of depolymerization-obstructing substances calculated as a total of a concentration calculated as diglycolic acid (of x wt. %) of hydroxyl group-free impurity carboxylic acids (A) and 100 times a concentration calculated as ammonia (of y wt. %) of nitrogen-containing substances (B), respectively with respect to the starting glycolic acid oligomer in the depolymerization system, to at most 15 wt. %.

摘要： Various component parts of a driver circuit for drive sources such as electric motors and clutches, such as relays and FETs as well as the drive sources can be tested by selectively energizing the relays and evaluating the voltage levels of the selected points by using the first and second test voltage detection circuits. This testing process is typically executed before the power up of the drive circuit. The test current is so small that the drive sources would not be inadvertently activated and various components would not be damaged even when there is any faulty component in the driver circuit. When any faulty component is detected in the testing process, the driver circuit may be prevented from being powered up so that any undesired operation of the drive sources or permanent damage to various components owing to such a faulty component may be avoided.
