Title: Method for providing multiple coaxial cable connections to a radio-frequency antenna without baluns
IPC: A61B5/055
Filed: 1989-09-15
Abstract: A method for providing plural coaxial cable connec­
tions, each to a different portion of a single radio-fre­
quency (RF) antenna without requiring the use of isolation 
means at any RF connection, determines at least a point 
within the antenna having a desired common potential adjacent 
to each of the different portions to which one of the coaxial 
cable connections is to be made; Then forms a separate seg­
ment of each different portion which is located substantially 
at the common potential and is reactively separated from ad­
jacent segments of the associated portion; and connects a 
shield conductor of an associated coaxial cable to the sepa­
rate segment, while connecting a center conductor of that 
same associated coaxial cable to a selected one of the adja­
cent segments of that different portion.

Title: Memory for programmable digital filter
IPC: H03H17/02
Filed: 1989-11-27
Abstract: The filter comprises an arithmetical chain of 
parallel adders (30, 32...34) alternated 
with delay elements (40, 42) and a 
memory constituted by a plurality of lines (12...20) of a 
plurality of one-bit cells, each being addressable by a 
decoder controlled by a digital signal to be filtered; 
each line of memory contains side by side values which 
correspond to the partial products of successive 
impulse-response coefficients for a value equal to the 
line address. The memory furthermore comprises a number 
of read amplifiers (22) which is equal to the number of cells 
of one line in order to read the bits of the addressed 
line, and the outputs of the amplifiers are connected to 
respective parallel inputs of the adders of the 
arithmetical chain. According to the invention, each 
memory line contains these values in two's-complement 
binary form in words which decrease in length by one bit 
for each increment of 2 in the characteristic of the 
coefficients, starting from the one of lowest 
characteristic, and the output of each read amplifier 
corresponding to the most significant bit of each value 
is connected to the corresponding input bit line of the 
associated adder and to all the other most significant 
input bit lines.

Title: Programmable bonding pad with sandwiched silicon oxide and silicon nitride layers
IPC: H01L27/102
Filed: 1989-01-23
Abstract: The present invention is a bonding pad 
structure and method for making the same which can be 
connected at the metalization step to form passive or 
active devices in addition to forming a bonding pad. 
A P-doped region (24) is formed in an epitaxial layer (28) 
in the area of the bonding pad (30) at the perimeter of 
a chip. This P-doped region (24) allows the formation 
of a junction capacitance between it and the epitaxial 
layer (28). In addition, by adding an oxide layer (32) 
over the P-doped region (34) an oxide capacitor 
can be formed between the metal bonding pad (30) 
and the P-doped region (34) with the oxide (32) as 
the dielectric. The oxide layer (32) is a special 
sandwich of two layers, silicon dioxide (36) and 
silicon nitride (37). The sandwiched layers protects 
the components beneath the bonding pad (30). The 
P-doped region (34) can also be used as a resistance 
by providing metal connections to both ends. Finally, 
a vertical PNP transistor can be formed between 
the P-doped region (34), the epitaxial layer (28) 
and a P-doped substrate (26).

Patent EP-0389071-A3 (EP)
IPC: B81C1/00
Filed: 1990-01-30
Abstract: A miniature transducer having an ultrathin 
tensioned silicon diaphragm so as to be responsive to 
extremely small changes in pressure. A silicon wafer is 
masked to define diaphragm areas, and etched to form a 
setback or capacitor gap a predefined depth. The mask 
is removed, and the entire silicon wafer is etched a 
second time to achieve the desired diaphragm thickness. 
The first and second etches are carried out 
independently, and thus the capacitor gap and diaphragm 
thickness can be independently formed. Mask and 
metallizing steps are carried out on glass wafers, and 
sandwiched around the processed semiconductor wafer, 
whereupon a large number of the miniature transducers 
are fabricated simultaneously. Unique patterning, 
etching and metallizing steps carried out on the 
sandwich structure allow a number of quadrature unit 
cells to be formed, thereby maximizing the area of the 
semiconductor and glass structures. By proper selection 
of materials, the diaphragm is tensioned during the 
fabrication of the transducer structures.

Title: Method of measuring average particle size of granular material
IPC: G01N15/02
Filed: 1990-03-05
Abstract: A method of measuring an average particle size of 
granules. The method computes the average particle size 
on the basis of an n-order moment M n  of an image of 
granules accumulated in a pile or of the image subjected 
to binarization or floating binarization. The method is 
capable of highly accurate and stable measurement on 
granules having many irregularities in the surface 
thereof and accumulated in a pile. The method can be used 
to continuously measure in real time the particle size of 
granules in a rotary tray of a rotary tray-type rolling 
granulating machine thereby adjusting the feed rate of a 
liquid binder to automatically control the particle size.
Patent EP-0390609-A3 (EP)
Title: Adjacent channel interference canceller with means for minimizing intersymbol interference
IPC: H04L27/01
Filed: 1990-03-30
Abstract: In a device for use in processing a device input 
signal carrying a digital symbol sequence, a reception 
filter filters the device input signal and produces a 
filter output signal having a high order curvature 
distortion. The high order curvature distortion results 
in a predetermined frequency band from adjacent 
interference on the prdetermined frequency band by 
other frequency bands adjacent to the predetermined 
frequency band. Responsive to the filter output signal, 
an adaptive amplitude equalizing unit equalizes the high 
order curvature distortion and produces as a first 
equalized signal. When the device input signal 
decreases, the adaptive amplitude equalizing unit 
overestimates the high order curvature distortion to 
produce intersymbol interference because of 
appropriately suppressing the other frequency bands by 
the reception filter. In order to resolve the problem, 
an adaptive transversal equalizing unit is connected to 
the adaptive amplitude equalizing unit and equalizes the 
intersymbol inteference along a time axis of the first 
equalized signal to produce an output signal with the 
curvature distortion and the intersymbol inteference 
suppressed.

Title: Vorrichtung zum Erkennen von Verunreinigungen, Fremdstoffen und -fasern in textilem Fasermaterial
IPC: G01N21/89
Filed: 1990-01-09
Abstract: Verunreinigungen der Rohbaumwolle durch andere Faserstof­
fe, Bänder oder Folien können mit den üblichen Reinigungs­
methoden nicht vollständig entfernt werden. Sie gelangen 
zum Teil bis in das Kardenband und führen dann im Garn zu 
Fadenbrüchen oder erst im Gewebe zu Fehlern und damit zu 
relativ hohen Kosten. Das beschriebene Verfahren ermöglicht 
ihre Erkennung im Vlies, Band oder Garn. Dazu wird das Fa­
sermaterial (1) mit mehrfarbigen Licht beleuchtet. Minde­
stens zwei Frequenzen des reflektierten Lichtes werden se­
lektiv empfangen und verglichen. Das Ausgangssignal der 
dazu verwendeten Differenzschaltung (7) wird durch eine 
Regelschaltung (8,9′) konstant gehalten. Infolge einer 
großen Regelzeitkonstante bewirken Fremdfasern eine spon­
tane Änderung des Ausgangssignals, sofern sie in der Farbe 
von der Rohbaumwolle abweichen.  
     Die beschriebene Vorrichtung gestattet zusammen mit ei­
nem Garnreiniger beim Umspulvorgang die Beseitigung von 
Fremdfasern, deren Farbe von der Rohbaumwolle abweicht.
