Phosphoric acid bath reads 150C but is actually at room
temperature.

The phosphoric acid bath temp controller needs calibration.
This will be done today.

heater for phosphoric acid bath doesn't seem to be working.  It 
is set to heat to 150 C and is only at 23-24 C after about 1 hour of 
operation.

Replaced phosphoric acid bath thermocouple. This 
repairs the problem as reported by Leslie.

>>> 'sink7' problem from cjkim -- Thu Mar 22 00:07:25 1990 <<<

spindryer for sink7&8 keeps slowly rotate(rpm ~ 2) after normal spin.
Had to turn off the power to stop it.

>>> 'sink7' problem from cjkim -- Thu Mar 22 01:49:46 1990 <<<

The slow rotation I previously reported did not happen this time.

spindryer2 stopped in mid-cycle several times.  other people were using
lots of nitrogen at the time.  wasn't able  to repeat the problem when
other nitrogen users stopped.

>>> 'sink7' fix from phillip -- Tue May  8 07:36:46 1990 <<<

Fabricated and replaced 'J' type thermocouple in
Phosphoric acid bath. The problem as reported
by Nam is fixed.
