Patent EP-0343554-A3 (EP)
IPC: H01H50/16
Filed: 1989-05-20
Abstract: Bei einem Relais mit E-förmigem Joch (5) und einem 
querverschiebbaren Anker (12) greift je eine von zwei 
Polplatten (14, 15) des Ankers (12) in einen Freiraum 
zwischen Jochaußenschenkel(5′) und Jochkern (7) ein. In 
jeder Betriebslage schlägt eine der Polplatten (14, 15) 
am freien Ende (10) des Jochkerns (7) an. Durch die nach 
einem Schaltvorgang verbleibende Restmagnetisierung des 
Joches (5) kann die am Jochkern (7) anliegende Polplatte 
(14 oder 15) an diesem haften bleiben. Diese Haftkraft 
muß beim Umschalten durch eine entsprechend hohe 
Ansprechleistung überwunden werden.  
     Am Spulenflansch (11) sind am Jochkernende (10) 
anliegende Anschlagrippen (22) angeformt, die breiter 
als die Dicke des Jochkerns (7) sind und in einer 
solchen Länge über den Durchmesser des Jochkerns 
überstehen, daß beim Anschlagen der Polplatte (14, 15) 
ein Spalt (23) zwischen Polplatte (14, 15) und Jochkern 
(7) verbleibt. Diese Maßnahme verhindert das Haften des 
Ankers und bewirkt zugleich dessen Dämpfung beim 
Anschlagen der Polplatte (14, 15).  
     Die Erfindung ist besonders geeignet für 
Miniatur-Flachrelais.

Title: Ink jet recording head and ink jet recording apparatus
IPC: B41J2/175
Filed: 1989-12-28
Abstract: In an ink jet recording device having an ink 
tank integrated type jet recording head (10) and a carriage (20) 
for mounting the head thereon, good electrical connection 
is obtained by constituting so that the electrical pad (13) 
of the connecting terminal (10a) of the recording head and 
the electrical pad (24) of the connecting terminal (20a) of the 
carriage are connected to each other while rubbing them 
one to one. Further, also by specifying the arrangement 
position of the positioning member, more accurate 
electrical conduction is effected and also breaking of 
the positioning member is prevented, thereby providing 
an ink jet recording device having high reliability in 
both aspects of recording and durability.
Patent EP-0349495-A3 (EP)
IPC: H02M3/07
Filed: 1989-06-16
Abstract: A wholly integrated, multistage, CMOS voltage multiplier 
utilizes as a diode structure for transferring electric 
charge from an input node to an output node of each stage 
an enhancement type MOS transistor, the gate of which is 
coupled to the same switching phase to which the output 
capacitor of the stage is connected by means of a coupling 
capacitor. During a semicycle of charge transfer through 
said MOS transistor, the coupling capacitor charges through 
a second MOS transistor of the same type and having the 
same threshold of said charge transfer MOS transistor, connected 
in a diode configuration between the output node of 
the stage and the gate of the charge transfer MOS transistor, 
in order to cut-off the latter when reaching a voltage 
lower than the voltage reached by the output node by a value 
equal to the threshold value of said second transistor. 
In this way, a significant voltage drop across the charge 
transfer transistor is efficiently eliminated, thus 
allowing the generation of a sufficiently high output voltage 
though having available a relatively low supply voltage.

densitometrischen Größen dürfen für eine optimale Anpassung 
an den Druckprozeß und an das Farbempfinden des menschlichen 
Auges verfahrenstechnische Einflüsse beim Drucken nicht außer 
Acht gelassen werden.  
     Es werden daher für die Einzel- und Mehrfarbenregelung 
Verfahren vorgeschlagen, die unter Beachtung der voneinander

Tonwertzunahme(n) und maximal zulässige Schichtdicke(n) - 
einen Soll-Ort (Soll1) ansteuern, der sowohl innerhalb der 
tolerierbaren Tonwertzunahme(n) (ZSoll ± ZTol bzw. 
ZSoll i  ± ZTol i ) als auch innerhalb der Farbtoleranz (ETol) 
bzw. Dichtetoleranz (DVTol), bzw. innerhalb des 
Toleranzraumes (TolR) liegt. Erfüllt der Soll-Ort (Soll1) 
nicht diese beiden unabhängigen Randbedingungen gleichzeitig, 
wird der Toleranzbereich der Tonwertzunahme(n) erweitert und 
ein Soll-Ort (Soll2 bzw. Opt) daraufhin geprüft, ob er nun 
gleichzeitig beiden Randbedingungen gehorcht.

Patent EP-0412575-A3 (EP)
Title: Stuffing decision circuit
IPC: H04J3/07
Filed: 1990-08-09
Abstract: A stuffing decision circuit is described which is used in an arrangement for the bit rate adaptation of two signals. It is necessary for the application of the stuffing decision circuit according to the invention that the signal with the higher bit rate is structured in accordance with frames and at least one stuffing decision must be made for each frame. To make the so-called waiting time jitter, which becomes noticeable during the recovery of the signal with the lower bit rate at the receiving end, largely removable, means are provided by means of which the time of the stuffing decision is randomly or pseudorandomly shifted by times which are short compared with one frame length. Due to this modulation of the decision time, the low-frequency jitter otherwise occurring is transformed into higher frequencies and can be easily filtered out by means of a phase-locked loop at the receiving end.

arranged to write the inverse data bit into the same position, and the 
comparator compares the output bit position of the RAM with the 
inverse data bit The result is stored in the shift register, which can 
be down-loaded for analysis.

Abstract: A power booster (10) comprises a power amplifier (5)and 
is coupled to a portable radio telephone (20) which 
transmits an RF signal at one of a predetermined set of 
power levels. A first detector (6) generates an output

the respective power levels. The reference signal 
rf, which indicates the required power level, is 
applied to a power control circuit (7) which controls 
the gain of the amplifier (5) to maintain the power 
output substantially constant at the required power 
level as determined by the value of the reference 
signal rf.

Abstract: Die Erfindung betrifft ein Verfahren zur Normierung eines 
Spracherkennungssystems auf ein Langzeitspektrum, um störende 
Einflüsse wie unterschiedliche Mikrofon-, Raum- und

in bekannten Spracherkennungssystemen verwendet werden, 
wird durch Substraktion des Mittelwertes der Cepstralvektorkomponenten 
von dem jeweiligen Cepstralvektor 
erreicht. Eine vorteilhafte Erweiterung des Verfahrens 
erfolgt durch adaptive Normierung durch gleitende Mittelwertschätzung 
mit einem Schleppfenster über der Zeit und
