Patent EP-0345508-A3 (EP)
IPC: H05K3/46
Filed: 1989-05-19
Abstract: Die Erfindung bezieht sich auf ein Verfahren zum Herstellen 
von mehrlagigen, gedruckten Leiterplatten aus mehreren, 
jeweils mindestens auf einer Seite ein Leiterbild tragenden 
und zwei Paßlöcher (8-11) aufweisenden Kernlagen (1, 2), zwei äußeren 
leitfähigen Decklagen (3, 4) und jeweils 
zwischen den Kernlagen (1, 2) und 
den Decklagen (3, 4) vorgesehenen, gelochten, klebfähigen 
isolierenden Zwischenlagen (5-7) (Pregpregs). Zur Ausrichtung der 
Leiterbilder auf den Kernlagen (1-2) weisen die Kernlagen (1, 2) jeweils 
zwei Paßlöcher (8-11) und die Zwischenlagen korrespondierende 
Löcher (16-19) auf. Durch die Paßlöcher (8-11) 
der Kernlagen und die Löcher (16-19) 
der Zwischenlagen (5-7) werden zwei Schnüre (23) eingezogen, die auf 
die Dicke des aus Kernlagen (1, 2) und Zwischenlagen (5-7) bestehenden 
Paketes abgelängt werden. Während des Warmverpressens 
verbleiben diese Schnüre (23) in den 
Paßlöchern (8-11, 16-19) und halten somit 
die Leiterbilder auf den Kernlagen (1, 2) zueinander ausgerichtet 
und schützen die Paßlöcher (8-11, 16-19) vor einem möglichen Harzfluß aus 
den Prepregs. Mit dem Verfahren lassen sich beliebig viele 
Schaltungsebenen in einem Warmpreßvorgang herstellen.

Title: Temperature compensation for potentiometrically operated isfets
IPC: G01N27/414
Filed: 1989-07-10
Abstract: Compensation for the temperature sensitivity of 
the output of a potentiometrically operated ISFET probe 
whose drain-source voltage and drain-source current are held 
constant is provided by using a Nernstian temperature 
correction of the difference between the ISFET output and 
the isopotential voltage of the probe and offsetting the 
resulting difference by the isopotential pIon value. An 
ISFET/NISFET pair provides a cancellation of variations due 
to manufacturing.

IPC: G02B6/44
Filed: 1989-07-21
Abstract: Optische Adern weisen meist Lichtwellenleiter (1) auf, 
die lose und mit Uberlänge in einer Schutzhülle (2) 
untergebracht sind. Längenänderungen durch 
Temperaturschwankungen führen zu erhöhten 
Dämpfungsverlusten, da die thermischen 
Ausdehnungskoeffizienten von Lichtwellenleiter (1) und 
Schutzhülle (2) sehr unterschiedlich sind.  
     Wenn man die Schutzhülle (2) mit einem steifen 
Stützband (3) wendelförmig umwickelt, verformt sich die 
Schutzhülle (2) wendelförmig und Schutzhülle (2) und 
Stützwand (3) sind umeinander gedreht, wodurch eine form- 
und kraftschlüssige Verbindung entsteht. Das Material des 
Stützbandes (3) sollte einen Ausdehnungskoeffizienten 
aufweisen, der dem des Lichtwellenleiters (1) nahezu 
entspricht. Durch die Biegungen der Schutzhülle (2) wird 
zusätzlich eine radiale Beweglichkeit des 
Lichtwellenleiters (1) erzeugt, so daß dieser axiale 
Längenänderungen der Ader bzw. des Kabels kompensieren 
kann.

Patent EP-0349240-A3 (EP)
Title: Water-absorbent resin and production process
IPC: C08F2/32
Filed: 1989-06-26
Abstract: This invention relates to a water-absorbent resin of 
new, novel type obtained from polymerization of a water-soluble 
ethylenically unsaturated monomer followed by surface treatment and, 
in addition, a process for producing this resin.  
     The water-absorbent resin in this invention has average 
particle diameter in a specially defined range and a narrow range of 
particle distribution. And furthermore, since the particle surface 
is treated with crosslinking, a balance is very good among water 
absorption properties, for example, between water absorption capacity 
and water absorption rate, and between gel strength and suction force. 
This water-absorbent resin is takable a angle-lacking, non-sphere 
shape and in a case of this type of shape, it is superior in such 
handling properties as falling off from an basis material being hard.  
     Since the production process in the present invention 
comprises crosslinking treatment for the particle surface of a 
specially defined water-absorption polymer, the crosslinking is 
performed with good efficiency and, a water-absorption resin being 
superior in a balance among water absorption properties is obtainable 
with an economic advantage. This specially defined water-absorption 
polymer particle is obtained by polymerizing a water-soluble 
ethylenically unsaturated monomer in a process of reverse-phase 
suspension polymerization, In the production process of this 
invention, since the aqueous monomer solution is chosen from those in 
 
 
a specially defined viscosity range and then, dispersed and suspended 
by using a specially defined dispersing agent, a specially defined 
water-absorbent resin is easily obtainable wherein, not only the 
average particle diameter is controlled by adjusting the viscosity of 
an aqueous monomer solution, but also the particle diameter 
distribution resulted is narrow.  
     In this production process, the particle shape can be 
changed by changing up and down the viscocity of an aqueous solution 
of monomer in the above-described specially defined range.  
     The water-absorbent resin in this invention, because it 
has the above-described properties, is preferably used for sanitary 
materials and the like.

Title: Speech-recognition circuitry employing nonlinear processing, speech element modelling and phoneme estimation
IPC: G10L25/00
Filed: 1990-08-17
Abstract: A phoneme estimator in a speech-recognition system includes energy detect circuitry for detecting the segments of a speech signal that should be analyzed for phoneme content. Speech-element processors then process the speech signal segments, calculating nonlinear representations of the segments. The nonlinear representation data is applied to speech-element modeling circuitry which reduces the data through phoneme specific modeling. The reduced data are then subjected to further nonlinear processing. The results of the further nonlinear processing are again applied to speech-element modeling circuitry, producing phoneme estimates. The phoneme estimates are rearranged and consolidated, that is, the phoneme estimates are uniformly labeled and duplicate phoneme estimates are consolidated, forming estimates of words or phrases containing minimal numbers of phonemes. The estimates may then be compared with stored words or phrases to determine what was spoken.

Title: Magnetic dispersions of ferrite particles with high magnetic energy product in flexible highly saturated nitrile rubber and methods of producing the same
IPC: H01F1/113
Filed: 1990-09-18
Abstract: A flexible magnetic blend composition is provided which is comprised of high energy ferrite magnetic particles in a flexible high temperature resistant and oil resistant polymer binder. The binder system is preferably a highly saturated nitrile rubber (HSN) or a polymer alloy of the same in which a HSN is the major polymer containing alloying polymers and/or additives which are compatible with processing, subsequent electron beam curing, and final product performance. The system binder is highly loaded usually from 55 to 65 volume percent with the high energy ferrite particles, i.e, barium and/or strontium ferrite particles, which can produce bonded magnets with a maximum energy product of at least 1.0 megagauss-oersteds, a remenance, Br, of at least 2000 gauss, a coercive force, Hc, of at least 1800 oersteds, and an intrinsic coercivity, Hci, of at least 2000 oersteds. The process for production of this system involves the binder system and ferrite particles being mixed, the ferrite particles oriented in a preferred direction during processing, then formed into a final geometry before being cured by high voltage electron beam radiation, preferably in excess of 3,000,000 electron volts. The electron beam curing in the solid state fixes dimensional stability, magnetic properties, oil, solvent, and chemical resistance of the part even when exposed to subsequent hostile temperature environments of 125<o>C or higher. Any off geometry parts or trim produced in the process prior to radiation curing can be recycled through processing several times without fear of premature cure.

Title: Printer with interchangeable print heads
IPC: B41J2/045
Filed: 1990-01-04
Abstract: The printer has a thermal printing head 20 which is 
interchangeable with an ink-jet printing head. Each of the heads 
can be mounted on a carriage on the printer and has terminals 23a 
for engagement with terminals on the carriage. The head 20 has an 
arm 27 which is detected by a photo-sensor on the carriage to

printing head does not have such an arm. The photo-sensor 
determines the appropriate set of pulse currents to be supplied by 
the electronic circuit of the printer through the terminals 23a to 
operate the printing head which is in use. Alternatively the nature 
of the printing head which is in use can be sensed electronically in 
dependence on the resistance of the resistors in the two heads.
