Cushions Piston about the upstroke, eliminating the need for shock absorbers. Raises the piston down stroke power. Now we have calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) as well as the resonant enhancement of valence photoemissionat the Ti 2p threshold for Ti2O3.
