Patent EP-0055411-A3 (EP)
IPC: H01L27/082
Filed: 1981-12-11
Abstract: An array of hundreds of devices may be simultaneously 
processed on a chip to sub-micron dimensions by estab­
lishing tiny active regions for each transistor surrounded by 
field oxide filled motes or slotted regions, wherein the slots 
are utilized to dope the substrate within the action region. 
The N type substrate is double energy boron planted through 
one surface to establish a P region to a given depth. This 
surface is oxidized and photoresist mask conventionally to 
open regions for the slots which are ion milled or ODE etched 
to a given depth. N+ regions are established by the slots by 
ion implanting at an angle such that the entire depth of the 
slot is not doped but rather the doping is confined to a region 
within the double energy P implanted depth. Drive-in 
diffusion enlarges the N+ areas for the emitter and collector 
and oxidation fills the mote insulating regions around the 
active area.  
     The oxide is stripped and the P region enhanced to P+ at 
the surface, with silox being deposited and opened for metal 
contacts to the P+ region for the base and the emitter and 
collector regions. The doping profile of the base region 
provides a potential barrier to minimize the flow of electrons 
toward the surface because the emitter electrons are chan­
neled through the less heavily doped part of the base region 
to the collector.

Title: Apparatus for and method of random vibration control
IPC: G01M7/00
Filed: 1983-12-22
Abstract: In order to ensure that the vibrations of a system under test (12) are in accordance with a reference spectral density Z(w), the system (12) is driven by a signal x<sub>n</sub>(t) provided by an inverse discrete Fourier transform (24) with random phases introduced by a function R<sub>n</sub>(w) and the response spectral density Y<sub>n</sub>(w) provided by a DFT 16 is brough into agreement with Z(w) by a feedback loop. Moreover, in order to ensure that this is done in one iteration, X<sub>n</sub>'(w) is derived from x<sub>n</sub>(t) by a DFT (26) and divided (28) by Y<sub>n</sub>(w) and the quotient is multiplied (30) with Z(w) to provide the new input X<sub>n</sub>(w) for the IDFT (24). The division cancels out the random factor which is present in both X'<sub>n</sub>(w) and Y<sub>n</sub>(w). The system thus equalizes both rapidly and stably.

Filed: 1983-07-19
Abstract: A fuel/air ratio control apparatus for a reciprocating 
engine used in light aircraft including a fuel metering 
apparatus (32) and a fuel/air ratio controller (40). The

of the aircraft and the metering apparatus (32) meters fuel 
flow (Wf) according to the mass airflow ingested into the

ratio (Wf/Wa (3)) for cruise conditions as derived from the 
exhaust gas temperature. These ratios are limited by a ratio 
(Wf/Wa (1)) based upon the maximum cylinder head temper­
ature tolerable for a particular flight condition.
