Patent EP-0229633-A3 (EP)
IPC: C23C16/48
Filed: 1987-01-07
Abstract: A beam of substantially coherent light passes through 
a window in a chamber and then through the chamber in a 
direction substantially parallel, and contiguous, to substrates 
in the chamber. The beam ionizes gases in a mixture in the 
chamber. The ionized gases combine to form a substance which 
becomes deposited on the substrate(s) as a layer or which etches 
a previously deposited layer on the substrate. As the beam 
moves through the chamber, it loses energy. Various individual, 
or combinations of, compensations for this loss of energy may 
include: (l) the substrate(s) may be tilted slightly to decrease 
the distance between the beam and the substrate(s) as the beam 
moves through the chamber; (2) the beam may be tapered in a 
direction along the substrate(s); (3) the rate and direction of 
the flow of a mixture of ionizable gases through the chamber may 
be adjusted; (4) the rate and direction of flow of a gas for 
neutralizing the ionization of the gases may be adjusted; (5) 
the rate of flow of the ionizable gases may be individually 
adjusted for each substrate; and (6) the rate and direction of 
flow of the neutralizing gas may be individually adjusted for 
each substrate. Lenses may be included in the window for 
producing the desired configuration of the energy beam. In 
another embodiment, the chamber may be disposed within a 
compartment. A first portion of the energy beam may be directed 
through the chamber. A second portion of the beam may be 
directed through a compartment area external to the chamber 
 
 
and may then be redirected to pass throuqh the chamber in a 
direction opposite to the first portion and at positions 
substantially parallel, and contiguous, to the substrate(s).

Patent EP-0293578-A3 (EP)
IPC: G11C11/411
Filed: 1988-04-12
Abstract: This invention relates to the layout of memory cells 
(1) and their associated pair of bit lines in such a 
way that very high density arrays are obtainable. The 
resulting memory cell array is one in which the bit 
lines (B02, B03) associated with each column of memory 
cells are interleaved with the bit lines of (B11, B12) 
adjacent columns of memory cells. By this means, 
regions of the semiconductor chip in which the cells 
are formed, which were formerly unusable, now become 
usable and cell area is significantly reduced. Because 
the spacing of metallic bit lines is governed by 
certain ground rules, cell length in the x-dimension 
could be reduced no further as long as metallic 
interconnections were used. To overcome this limita­
tion, polycrystalline fingers or extensions (13) are 
substituted for metal cross-coupling interconnections. 
Because polycrystalline interconnections have less 
stringent requirements relative to their spacing, 
using such interconnections in conjunction with 
metallic straps (14) which are shorter than the widths 
and spacing of two metallic interconnection lines 
again provides a significant reduction in the x-­
dimension and hence in cell area. When interleaved bit 
lines, polycrystalline fingers (13) and straps (14) 
are used at the same time instead of metal intercon­
nections, both approaches provide a memory cell area 
which is significantly improved over cell areas when 
neither or only one of the approaches taught are used. 
The method and structure taught may be utilized with 
both bipolar and unipolar devices.

Patent EP-0301652-A3 (EP)
Title: Radiation detector arrangements and methods
IPC: G01T1/12
Filed: 1988-07-18
Abstract: Infrared, mm-wave or other radiation (100) is detected with 
at least one detector element in the form of a 
temperature-sensitive resistor (1) having a high positive 
temperature coefficient, e.g. 100 micro-ohm.cm.K⁻¹. A 
sufficiently high voltage V is applied across the resistor (1) by 
means of a circuit (Vb,T1) so that, in accordance with the 
invention, the resistor (1) passes a sufficient current (I) as to 
raise its temperature by Joule heating to a position at which a 
further increase in its temperature in response to incident 
radiation (100) reduces the Joule heating by reducing the 
current (I), thereby stabilizing the temperature of the 
resistor (1). This varying current (I) through the resistor (1) 
is measured (e.g. as a voltage V′ by means of a transconductance 
amplifier A) to provide a signal indicative of the power of the 
incident radiation (100). The change in the Joule heating 
produced by a change in the temperature of the resistor (1) at 
this position is larger (e.g. more than 10 times larger) than a 
change in power of the incident radiation (100) required to 
produce that same change in temperature of the resistor (1) in 
the absence of any change in Joule heating. As a result of this 
internal stabilization of its temperature due to the changes in 
Joule heating, the detector element (1) has a short time constant 
for response, and thermal cross-talk problems do not arise for an 
array of the detector elements (1) sharing a common body of the 
resistance material. The resistance material may be, e.g., a 
semiconducting barium titanate operated around or above ambient 
temperature, or an oxygen-deficient mixed oxide of barium, copper 
and yttrium which is superconducting when cooled below its high 
positive temperature coefficient. The resistor(s) may be mounted 
on a semiconductor circuit, possibly on a cryogenic cooler.

Abstract: An encoder device encodes angular position in the form 
of electrical signals in dependence on the position of a 
rotatable member in relation to a series of discrete fixed 
contacts disposed about the axis of rotation of a rotatable 
member. A series of discrete fixed contacts 2a,2b, carried 
by a panel 1 form a first group of contacts of a flexible 
switch structure which also has a second group of contacts 
9 carried by a flexible sheet 7 and arranged such that 
each contact of said second group is located opposite but 
spaced from one of the series forming said first group of 
contacts. An intermediate sheet 8 is sandwiched between the 
panel 1 and flexible sheet 7 and is apertured at 10 in the 
region of the contact sets 2a,2b and 9. The rotatable member 
carries a switch actuating means 14 which operates to close 
any of the oppositely disposed first and second contact sets, 
in dependence upon its angular position, said switching 
actuating means being such that either one contact set is 
closed or two adjacent contact sets are closed for any 
angular position of said rotatable member. The output is 
derived from terminal areas 6 on the panel 1.

Abstract: Scrap poly(ethyleneterephthalate) is converted 
to useful amine and diamine monomers such as 
para-xylylenediamine, 1,4-bis(aminomethyl)cyclo­
hexane and 4-aminomethyl benzoic acid for the 
production of various polyamides. The conversion of 
poly(ethyleneterephthalate) to diamine monomers is 
achieved by a three step process involving (a) 
ammonolysis of the poly(ethyleneterephthalate) to 
produce terephthalamide and ethylene glycol; (b) 
pyrolytic dehydration of the terephthalamide to 
produce terephthalonitrile; and (c) hydrogenation of 
the terephthalonitrile to produce the para-xylylene 
diamine and/or 1,4-bis(aminomethyl)cyclohexane. The 
conversion of poly(ethyleneterephthalate) to 
4-aminomethyl benzoic acid involves the steps of (a) 
ammonolysis of the poly(ethyleneterephthalate) to 
produce terephthalamide; (b) partial pyrolytic 
dehydration of said terephthalamide to produce 
4-cyanobenzoic acid; and (c) hydrogenation of said 
4-cyanobenzoic acid to produce 4-aminomethylbenzoic 
acid. The process of the present invention permits 
the conversion of low value PET scrap such as 
beverage bottles, fibers and film to relatively high 
value and relatively pure diamine monomers and 
ethylene glycol.

Title: Method for initializing or synchronizing a communication link
IPC: H04J3/06
Filed: 1989-09-28
Abstract: The initialization or synchronization method sends out at 
least a predetermined number of synchronization messages over a 
two-way communication line between transmitters (7) and receivers 
(8) at two communication stations(6). The receipt of a 
synchronization message is awaited before terminating the 
transmission of synchronization message. After the transmission 
of synchronization messages has been terminated, the receipt 
of a non-synchronization message will complete the synchronization 
process. However, certain conditions may cause synchronization 
to be restarted such as a predetermined number of consecutive 
error messages, failure to receive any message in a predetermined 
number of clock signals, receiving more than a predetermined 
number of synchronization signals, or a reset command.
