Patent EP-0314476-A3 (EP)
Title: Feedback threshold compensation
IPC: H03K19/0952
Filed: 1988-10-27
Abstract: A V BB  input (18) 
threshold potential with feedback circuitry 
is used to stabilize all of the logic inputs on a GaAs IC to ECL 
compatible levels over a normal temperature range and normal 
power supply variations. The system called "V BB -Feedback" uses 
"zero translation delay" direct Capacitor Diode Fet Logic (CDFL) 
inputs. This is an extension of the CDFL circuit approach in 
which the voltage across the input level shift circuitry on all 
inputs is adjusted to maintain a threshold voltage equal to the 
dc potential on an "extra" V BB  
input (18) in spite of variations of 
temperature, power supply voltages or processing parameters such 
as MESFET pinchoff voltage. A dc potential (V BB ) is applied to 
the "extra" V BB  input (18), 
which is an additional input that is 
essentially identical to the actual logic inputs. All of the 
logic input threshold voltages are then slaved to the V BB  dc 
potential applied to the "extra" V BB  input. ECL compatability is 
accomplished by combining a reasonably compliant, but uniform, 
CDFL voltage shifter (34) with feedback circuitry (55) to maintain the 
shift voltages at proper levels thereby achieving the desired 
input logic threshold.

Patent EP-0393702-A3 (EP)
IPC: G10H1/12
Filed: 1990-04-20
Abstract: The present invention provides a signal delay circuit for 
substantially steplessly changing a delay interval. The signal 
delay circuit is composed essentially of a delay controller, a 
first delay circuit, and a second delay circuit. The delay 
controller generates and outputs control data consisting of a 
real number bearing control information for controlling the 
delay interval, the real number consists of an integral portion 
and a fractional portion. The first delay circuit receives an 
incidental signal, delays the incidental signal for creating a 
first intermediate signal, and outputs the first intermediate 
signal, the first intermediate signal being delayed with 
respect to the incidental signal by an interval which is a 
product of a predetermined cardinal interval and the integral 
portion of the real number. The second delay circuit receives 
the first intermediate signal, produces at least one second 
intermediate signal by delaying the first intermediate signal 
by at least one interval which is an integral multiple of the 
predetermined cardinal interval, interpolates the first 
intermediate signal and said at least one second intermediate 
signal for producing a delayed signal, and outputs the delayed 
signal, the delayed signal being delayed with respect to the 
first intermediate signal by an interval which is a product of 
the predetermined cardinal interval and the fractional portion 
of the real number. As a result, the delayed signal is delayed 
with respect to the incidental signal by a delay interval which 
is a product of the predetermined cardinal interval and the 
real number output by the delay control means.

Abstract: The use of alternating n and p type regions asymmetrically spaced in a 
semiconductor material yields extremely advantageous properties. In particular, by 
controlling the doping level and the spatial configuration of the doped region both 
the device response and its optical properties are controllable. Therefore, in 
applications such as those involving optical switches LEDs, lasers and long 
wavelength detectors, both the speed of device and its optical properties are 
controllable. As a result, greater fabrication flexibility than previously available is 
possible.
Patent EP-0395334-A3 (EP)
Title: Spring lock washer for tie rod nuts
IPC: G21C3/33
Filed: 1990-04-23
Abstract: In a nuclear fuel bundle, an improved lock washer 
is disclosed for permitting ease of remote removal of hex 
nuts on tie rods for the remote submerged disassembly of 
fuel bundles after use in a reactor. The improved lock 
washer includes two spaced apart and interconnected tie rod 
surrounding washer members (30,32), each having radially 
inwardly extending keys (40). These keys register to 
corresponding keyways (42) in the threaded ends (44) of the 
tie rods to prevent tie rod rotation and threaded disengage­
ment from a tie plate at the other end. Each washer member 
is manufactured from a spring material and includes at least 
one and preferably two radially protruding tangs (50). 
These tangs are elongate and bent in an inverted U-shaped 
configuration, including a gradual inward slope (66) 
defining a gathering surface between the tie rod and bolt on 
one hand and the U-shaped tang on the other hand. From the 
end of the gathering surface, the tang extends vertically 
downward in a position of spring interference with one of 
the flat sides of the hexagonal bolt (72) holding the tie 
rod in place. When the tie rod washer is in place with the 
nut fastened, the tang prevents the bolt from turning 
responsive to vibration and upward force on the upper tie 
plate due to outflowing water and steam. In remote dis­
assembly of the fuel bundle, the gathering surface permits 
the tang to be biased away from the sides of the bolt by a 
specialized nut-gripping socket that penetrates intersti­
tially between the lock washer and nut and captures the nut 
when it is unscrewed. The lock washer because of its spring 
action returns to its initial shape after the socket and nut 
are removed.
