Shutdown gasonics SNF 2004-12-22 15:38:40: unload cassette intermittently resets

[eenriquez at snf.stanford.edu]

Found the voltage regulator on the unload cassette controller was over heating.  Will order a new 5 volt regulator.  Installed a heat sink (strips of copper tape) on the regulator and using CDA to cool down the regulator.
