The present invention is a low pressure physical vapor deposition method for the deposition of multi element sulfide thin film phosphor compositions for electroluminescent devices where a thermal source comprising a polysulfide compound provides the source of sulfur species for phosphor film deposition andor annealing. The tissue sensor is operable to sense a tissue sample severed by the cutter. Setting the flow rate of the slurry into the sluice such that the gold particles are attracted to the gold collecting medium. The resulting door skins have an improved bond strength, and are efficiently manufactured. The detection circuit receives the output signal and clock signal and detects whether the output error has occurred to generate a detection result.
