wafer shattered while spin drying.  wiped out big pieces with hands
and vacuumed out small pieces.  tried it out twice afterwards and
appeared to work ok.

P: Door opens during cycle. Dry time cycle does not complete.
S: Correctly set bladder seal pressure to door. The
   spindryer2 is now working satisfactory.

Status: R

Adjusted door seal n2 regulator as to keep the door from opening
midcycle. The spindryer2 should be o.k. now.

The bladder on the door of spindryer2 is leaking badly where it is
fed by N2 causing a loss of pressure. The spindryer2 is useable
however this bladder should be replaced. I will look for a spare
and replace it if I find one.

>>> 'spindryer2' problem from evan -- Thu Jun 22 13:58:49 1989 <<<

problem:leaky bladder
solution: replaced door bladder/seal
At first, door would oscillate due to imbalance in n2 settings.  Adjusted
door regulator until it would stay shut while unit spins.

spindryer2 is up

>>> 'spindryer2' problem from evan -- Thu Jun 22 15:25:07 1989 <<<

Motor not running. It starts but something is causing it to cut out.

>>> 'spindryer2' problem from bob -- Fri Jun 23 09:17:29 1989 <<<

{Spindryer2 appears to be operating however the start button has to 
be held in for 2-3 seconds in order to assure startup. If it has
further problem, these will be investigated.

>>> 'spindryer2' problem from phillip -- Fri Jul 14 07:10:17 1989 <<<

P: Ken Jordan reports that the dryer will not stop.
S: Adjusted door closing and input n2 pressures.
   This machine must play out its entire cycle before
   coming to a complete stop. That can be 15 to 60
   seconds after the 'stop' button is activated.
This unit is up and working.

>>> 'spindryer2' problem from bill -- Sat Aug 12 18:54:19 1989 <<<

The door will not seal properly and the speed seems independent
of the setting ( and very high ).
I wiped the seal with a clean wipe and tightened all the screws
holding the gasket in place ( many were very loose ) - but 
received no improvement.
I left the dryer with the power off and a note on the door.

I found the dryer with the power off ( no note or problem reported ) !
Now I know why it was left with the power off -
Please report problems instead of leaving them to be discovered.

>>> 'spindryer2' problem from phillip -- Mon Aug 14 07:43:29 1989 <<<

P: Door will not seal.
S: Adjusted n2 interlock,supply regulator, and door alignment.
   The problem as reported by Bill is fixed.

>>> 'spindryer2' problem from phillip -- Mon Sep 11 13:14:17 1989 <<<

P: Spins of its own accord. Rotor turns regardless of 
   state.
S: Solenoid to bimba 'stuck' operated. The problem cleared
   while tracing. Could not get it to reproduce.
   This machine is up.

Problem: spindryer2 huffs and puffs and the door pops open ever
so slightly when wafers are *trying* to be dried...

>>> 'spindryer2' problem from phillip -- Mon Oct  9 13:32:45 1989 <<<

Increased n2 pressure (slightly) to 33 psi.
The report by Marilyn is fixed.

>>> 'spindryer2' problem from jimmoon -- Wed Nov  1 09:01:12 1989 <<<

Won't spin dry.  Door keeps popping open and the thing never
gets going.

>>> 'spindryer2' problem from tom -- Mon Nov  6 14:49:15 1989 <<<

Problem:    User reports door does not stay shut.
Cause:      Unknown.
Solution:   Tried it several times. It works fine.

>>> 'spindryer2' problem from cjkim -- Wed Dec 20 15:51:50 1989 <<<

The door wouldn't close tight when activated.  Also strong vibration.

>>> 'spindryer2' problem from cjkim -- Wed Dec 20 16:08:12 1989 <<<

Readdressing the problem---.  There is no vibration -- mistake on my part.
Suspected: The tube along the rim of the door is not pressurized.  Loose tube?

>>> 'spindryer2' problem from evan -- Wed Dec 20 17:06:25 1989 <<<

I checked the door seal bladder and found no leaks.  I cleaned it in ultrasonic
and replaced.  Fidgeting with air regulators, internal and external, did not
solve problem.  I will leave it for phillip to fix in the morning.  It seems
to me like the chamber exhaust is plugged somehow and all the n2 must come out the door.  Just a guess.

>>> 'spindryer2' problem from phillip -- Thu Dec 21 07:03:54 1989 <<<

The spindryer2 is working normally as of this writing. The fix that
Evan applied yesterday must have 'took'.

>>> 'spindryer2' problem from marilyn -- Wed Feb 28 11:38:18 1990 <<<

Problem: At end of drying time, the spindryer2 inside cassette keeps
         "cartwheeling"; must be stopped manually in order to retrieve
         wafers.

>>> 'spindryer2' problem from bob -- Wed Feb 28 14:17:48 1990 <<<

The spindryer2 has two problems:

1. Fails to completely stop at the end of a cycle. Gentle hand
   pressure will stop it.

2. Door bladder fails to inflate.

spindryer2 is useable as is. The problems will be looked into when 
time permits.

>>> 'spindryer2' problem from phillip -- Fri Mar  2 08:19:18 1990 <<<

P: Door blatter fails to seal.
S: Set internal regulation of n2. Applied 'position
   keeper' on regulator to keep it from drifting again.
The spindryer2 is up.

>>> 'spindryer2' problem from phillip -- Fri Mar 23 13:53:16 1990 <<<

P:1. Spinner remains in motion while the unit is 'off'.
     This happens occasionally.
  2. Door pops open during cycle.
S:1. Constant motion is being looked in to.
  2. Requlator adjustment stopped the door opening problem.

Spindryer2 (between sink7 & 8) is available for use.

>>> 'spindryer2' problem from phillip -- Mon Mar 26 14:14:18 1990 <<<

P: Rotor continues turning when cycle is complete.
S: Pressure interlock switch not operating.
   New switch ordered-e.t.a.1 week
Until then, the machine is available for use.

>>> 'spindryer2' problem from phillip -- Mon Apr  2 06:59:31 1990 <<<

P: Dryer stops midcycle (when local n2 consumption
   goes beyond normal quantity.)
s: No trouble found. This equipment WILL NOT OPERATE
   coincident with spindryer1 or when n2 operate pressure
   is curtailed for whatever reason.
