Patent EP-0141571-A3 (EP)
IPC: H01L27/08
Filed: 1984-10-16
Abstract: A process, is disclosed for forming self aligned metal 
gate CMOS devices with guard rings isolating the active 
devices from each other and comprising only three mask 
steps prior to the contact mask where etching is done to 
contact junctions. The process is specifically defined for use 
with two layers of metal; the first metal layer provides source 
and drain contacts and spans the gate, the second metal 
layer providing device intraconnections. The three masking 
steps that are provided are a P well mask for defining the 
region in which N type devices are to be defined; a mask for 
defining the N type devices and guard rings; and a boron 
mask for defining the devices of the opposite type. (The 
sequence may, of course, be used to first define an N well, 
followed by diffusion of P type and then N type devices.) By 
the use of this sequence of masks, the active devices may be 
accurately placed, the gates are self aligned and by the use in 
combination therewith of low temperature controlled pro­
cessing, very fine channel lengths are achieved. Further, the 
major surface of the device is very flat having no large steps 
either in the field areas between the devices or in the areas of 
the active devices.

Abstract: An output circuit amplifier has first and second stage 
amplifying transistors (Q2,Q3) with an impedance circuit 
(D1,D2) connected between the base of the first stage 
transistor (Q2) and the collector-emitter circuit of the second

emitter circuit of the first stage transistor (Q2) is connected 
directly to a positive voltage bus (V+) to avoid further 
saturation problems.

Title: Process for producing a product hydrocarbon having a reduced content of normal paraffins
IPC: C10G47/16
Filed: 1987-01-05
Abstract: A waxy hydrocarbon feedstock is converted into a product hydrocarbon of reduced normal paraffin content by either dewaxing or hydrodewaxing the feedstock in the presence of a dewaxing or hydrodewaxing catalyst under conditions such that the normal paraffin content of the feedstock is reduced by selectively converting waxy paraffins into lower molecular weight hydrocarbons. At least a portion of the effluent from the dewaxing or hydrodewaxing zone is then passed to a hydrocracking zone where it is contacted with a hydrocracking catalyst in the presence of hydrogen under conditions such that a further reduction in the normal paraffin content is effected. When the desired product is a lube oil base stock, the overall conversion of components in the feed boiling above about 345 DEG C (650 DEG F) to components boiling at or below about 345 DEG C (650 DEG F) that takes place in the dewaxing or hydrodewaxing step and the hydrocracking step combined is no more than about 20 volume percent, preferably no more than about 10 volume percent. When the desired product is a middle distillate, the overall conversion of feedstock constituents in the dewaxing or hydrodewaxing step and the hydrocracking step combined to components boiling below about 150 DEG C (300 DEG F) is no more than about 25 volume percent, preferably no more than about 15 volume percent.

IPC: G21C1/02
Filed: 1987-01-20
Abstract: In a liquid metal cooled fast breeder nuclear 
reactor of the pool type, the hot and cold pools (13, 19) 
are separated by an intermediate plenum (24) which, under 
steady state conditions, encloses a volume of 
substantially stagnant liquid metal to form a thermal 
barrier between the hot and cold pools (13, 19). To 
avoid undesirably large temperature differentials 
developing for example in the event of large temperature 
excursions within the hot pool (13) as a result of a 
reactor trip, the intermediate plenum (24) is designed to 
permit, in such circumstances, rapid interchange of 
liquid metal coolant between the hot pool and the 
intermediate plenum, for example by way of a thermal 
siphon arrangement (30).

Abstract: A stereoscopic image projection system (10) employs an 
image encoder and an image decoder that are separated by a 
transmission medium (64) having a nondepolarizing projec­
tion surface (66) of the reflecting type positioned within it. 
The image encoder comprises plural color cathode ray tubes 
(12, 14, 16) and an equal number of variable optical retarders 
(36, 46, 52). Each variable optical retarder is positioned to 
receive from a different cathode ray tube first and second 
perspective view images carried on light rays of orthogonally 
related polarization states. Each cathode ray tube emits light 
of a color which is different from that emitted by the other 
cathode ray tubes. The image decoder comprises only 
passive optical elements. In a preferred embodiment, the 
imaging system uses three variables optical retarders to 
encode in red, green, and blue the first and second 
perspective view images by selectively developing, respec­
tively, zero and half-wave retardation of light passing 
through them. A passive viewing apparatus employs two 
neutral linear polarizing filters (68, 70) with orthogonally 
related absorption axes that receive the light reflecting off 
the screen. The polarizing filters pass light of a different one 
of the polarization states, and thereby pass a different one of 
the first and second perspective view images of multi-­
coloured aspect.

Title: Transmission system using forward error correction
IPC: H04J3/07
Filed: 1987-06-18
Abstract: In a high-speed fiber-optic tranmission system, data streams are synchronized using fixed stuffing before being multiplexed for transmission. The fixed stuffing information is replaced with forward error correction (FEC) information, whereby FEC is effected without any increase in transmission speed. FEC information blocks of each data stream can be synchronized to the frame timing of the transmission system, or they can be relatively unsynchronized. In the latter case, an FEC decoder acts in a self-framing manner to synchronize itself to the FEC information blocks of the respective data stream.
