IPC: B43M7/02
Filed: 1986-11-25
Abstract: A thickness monitoring device wherein a linear variable 
differential transformer (LVDT) device is operatively coupled 
with a pinch roller mechanism so that variations in thickness which 
are detected as an object passes through the pinch roller 
mechanism are converted, by the LVDT device, to electrical signals

IPC: G11C27/02
Filed: 1988-06-17
Abstract: An improved operational transconductance amplifier (OTA) for use in 
sample-and-hold circuits or the like requiring very low output leakage currents and 
equalized output current transients when the OTA is placed in stand-by (disabled.) 
The OTA has an output stage that is referenced to ground by having two 
darlington pairs with common collector outputs as the output for the OTA in a 
common base configuration such that when the OTA is disabled, any leakage 
paths from the output of the OTA are coupled to ground. Further, the OTA is 
compensated internally to equalize any current transient output when the OTA is 
placed in stand-by such that the integral of the current transient out of the OTA is 
substantially the same as the integral of the current transient into the OTA from 
the integrator. A sample-and-hold circuit is also described utilizing the improved 
OTA.
