Various embodiments concern a suspension having a DSA structure on a gimbaled flexure. The first pontoon is positioned on one side of the bulkhead and the second pontoon is positioned on the opposite side of the bulkhead. Upon start-up of the operation, the organic solvent is previously filled in the solvent filling portion via the solvent feed line and the solvent draining line, first, and then, the high temperature and high pressure water is fed from the water feed pipe to the hydrolyzer. In most cases, two or more processors are not performing a semaphore management sequence to the same address at the same time. In the event the handpieces collectively draw more power than the power supply can provide, the control console temporarily stops the application of power to one of the handpieces.
