Patent EP-0323228-A3 (EP)
Title: Route end node series preparing system of navigation apparatus
IPC: G01C21/00
Filed: 1988-12-28
Abstract: A system for preparing a route end node 
series which is equipped with a route search means (7) for 
preparing a node series, an intersection series or a 
combination of both as the data series for navigation, and a 
route end node series preparing means (3) for preparing the 
node series from the starting point and the destination to 
the respective nearest particular points. The route end 
node series preparing means (3) prepares node series by 
successively performing node search until the node nearest 
to the point indicated by the positional information on the 
starting point or the destination is attained.  
     This construction makes it possible to perform course 
guidance through navigation based upon the node series 
between the starting point or the destination and the 
nearest intersection thereto even if the starting point or 
the destination is set at a point between intersections when 
particular points are set as intersections.

IPC: H04N5/278
Filed: 1989-01-05
Abstract: Das Verfahren und die Vorrichtung finden Anwendung in 
der Fernseh-Studiotechnik und sichern eine unveränderlich 
hohe Qualität des Programmsignals nach Einführung von 
Symbolen in dasselbe. Diese sind auch in einem Studio, 
das nach dem Standard SEKAM arbeitet, anwendbar. Das Ver­
fahren besteht im Summieren des Programmsignals und des 
Symbolsignals, das nach dem Pegel so formiert ist, daß 
sein Wert stets kleiner oder gleich dem Unterschied des 
Helligkeitspegels des im Bild übertragenen Symbols und 
des Momentan-Helligkeitspegels des Programmsignals ist. 
Der Helligkeitspegel des im Bild übertragenen Symbols 
ist konstant (maximal oder Null) oder verändert sich in 
Abhändigkeit von Momentan-Helligkeitspegel des Programm­
signals.  
     Die Vorrichtung findet Anwendung in der Fernseh-Studio­
technik bei allen standarten Systemen für die Farbigkeits­
übertragung. Einen besonderen Vorteil hat ihre Anwendung 
bei SEKAM-Signalen, weil die Mischfunktion ohne Frequenz­
teilung des Farbigkeitssignals und ohne seine Demodulation 
erfolgt. Es wird das Adaptiv-Verfahren zum Formieren des 
Pegels des graphischen Signals benutzt. Die Adaptivität 
gegenüber dem Signal wird in Bezug auf den optimalen End­
kontrast der insertierten Graphik gemäß der laufenden 
Helligkeit fortgesetzt, was außerdem einen neuen Effekt 
der Durchsichtigkeit des insertierten Bilds schafft. In 
der Vorrichtung werden einfache und beständige Translatoren 
 
 
der Pegel des Eingangs-Videosignals mit einer End-Schlüs­
selbearbeitung benutzt, bei welchem außer einer hohen 
Beständigkeit und Genauigkeit auch ein erhöhtes Signal/­
Rauschverhältnis erreicht wird, weil der Kanal für die 
Bearbeitung geschlossen ist, wenn kein Signal für Inver­
tieren vorhanden ist.

IPC: G06F12/00
Filed: 1989-12-19
Abstract: A dual port read/write register file memory 
includes means for performing a read/modify write cycle 
of operation within a single system cycle of 
operation. The register file memory is constructed 
from one or more (RAM) addressable multibit storage 
arrays organized to form a dual read port, single write 
port RAM (10-1). Additionally, the register file includes a 
plurality of clocked input registers (10-3) arranged in pairs 
for storing command, address and data signals for two 
write ports. The different pairs of registers are 
connected as inputs to a first set of multiplexer 
circuits (10-5) whose outputs connect to the write control 
signal, address and data inputs of the single write 
port. The single write port of the register file 
memory is enabled for writing twice during each cycle. 
This allows data clocked into the input registers 
during the previous cycle to be written sequentially 
into the register file storage locations. By writing 
data into the input registers instead of the register 
file memory in a previous cycle, the time required for 
writing is reduced to a minimum.

Title: Semiconductor with filled-by-flow trench isolation
IPC: H01L21/762
Filed: 1990-04-30
Abstract: A trench which provides electrical isolation between transistors on an 
integrated circuit substrate is described. The trench is lined with a diffusion barrier, 
typically a thermal oxide followed by a thermal stress relief layer, typically formed 
from TEOS. Then a filler material, typically BPTEOS, is deposited to fill the trench 
and cover the upper surface of the wafer. The filler material is heated to make it 
flow. Next the outer surface of the flowed filler material is next subjected to an 
etch-back which makes the top surface of the filled trench protrude slightly above the 
upper surface of the substrate. The resulting trench contains the diffusion barrier 
layer, the thermal stress relief layer, and the filler material. The filler material and 
the thermal stress relief layer will soften during subsequent heat treatments of the 
wafer, thus relieving thermal stresses, and preventing the occurrence of defects and 
dislocations within the wafer.

Title: Line arrangement for compensating cross-talk
IPC: H04B3/32
Filed: 1991-10-04
Abstract: A line device, preferably a line terminating device (LE) of a communication system which contains transmitting and receiving circuits (S1, S2, SN; E1) to which transmitting lines (SL1, SL2, SLN) and receiving lines (EL1) are connected, contains at least one receiving circuit (E1) comprising a circuit arrangement (KS) for compensating for crosstalk. A single circuit arrangement (KS) compensates for the crosstalk from several transmitting lines (S1, S2, SN) to one receiving line (EL1). For the compensation, a reference signal (R(1)1, R(1)2, R(1)N) of the transmitting signal is branched off from each transmitting circuit (S1, S2, SN) and a compensation signal (K1, K2, KN) is simulated by an adaptive filter (F1, F2, FN). The individual compensation signals are additively mixed with the receiving signal via subtraction inputs of a subtraction circuit (S). A part of the output signal of the subtraction signal (S) is supplied to the control signal inputs (RS1, RS2, RSN) of the adaptive filters (F1, F2, FN), the other part is processed further to become the receiving signal (DA1).

Filed: 1991-03-20
Abstract: A dispensing gun for viscous materials comprises a stock (12) supporting a push rod (28) which is advanceable along a keep (13) in which is mounted a cartridge of the material. The rod is advanced by means of a catch plate (41) and trigger (43) arrangement which bites on the rod and is retreated by a return spring (42). A release plate (51) prevents the rod retreating with the catch plate. The release plate is frictionally engaged with the rod so that it acts as a lost motion brake once force is removed from the trigger. In this way the rod is allowed a limited retreat to take the dispensing force off the cartridge to prevent leakage when the trigger is not depressed. <IMAGE>
