Patent EP-0335487-A3 (EP)
IPC: G01Q60/00
Filed: 1989-02-15
Abstract: A method for recording, reading and erasing data bits in a data storage 
device is described. Using extended scanning tunnelling microscopy 
(STM) techniques, a tunnelling electron current by resistive heating 
selectively melts discrete areas of a state-transformable film; then 
heat is dissipated rapidly, writing data bits by changing the film in 
the areas from a first state to a second state wherein an electronic 
property, such as conductance, work function or band gap, in the areas 
is changed. Again, using extended STM techniques, the effect of this 
changed electronic property of the film on the tunnelling current is 
measured for reading the written data bits. Minimising the effect of 
blemishes on the material is effected, during operation in STM constant 
current mode by measuring dI/dV or dI/ds, and during operation in STM 
variable current (constant gap) mode by measuring (dI/dV)/I or 
(dI/ds)/I. Also, by using extended STM techniques, data bits can be 
selectively erased by resistance heating the film to a temperature 
higher than the crystallisation temperature for a sufficient period of 
time, restoring selected discrete areas to the first state and each 
affected electronic property substantially to its original condition.

Title: Analog-to-digital converter and method
IPC: H03M1/52
Filed: 1989-11-30
Abstract: There is provided according to the invention a 
method and apparatus for eliminating or minimizing the 
error due to amplifier offset or drift error in an 
integrating dual slope analog-to-digital converter. 
The converter is provided with a switching and control 
arrangement whereby the integrating capacitor is 
charged for one-half of the predetermined charging time 
as a function of the sum of the levels of the unknown 
signal and the error signal. The integrating capacitor 
is charged for the remaining half of the predetermined 
time period as a function of the difference of the 
levels of the unknown signal and the error signal so 
that the capacitor reaches a level of charge which is a 
function of the level of the unknown signal 
substantially unaffected by the level of the error 
signal. During deintegration of the capacitor by a 
reference signal the polarity of the error signal is 
inverted during successive or consecutive deintegration 
cycles so that the error voltage is self-cancelling in 
two successive deintegrations and is eliminated from 
the summed digital output.

Patent EP-0387467-A3 (EP)
Title: Switched reluctance motor and operating method
IPC: H02K19/10
Filed: 1989-10-05
Abstract: A switched reluctance motor has its stator poles 
divided into at least three phases, each phase having its 
own independently switchable phase windings wound around 
the corresponding stator poles. First switch elements 
control application of power to the windings of the first 
phase, second switch elements control application of 
power to the windings of the second phase, and third 
switch elements control application of power to the 
windings of the third phase. For low speed operation of 
the motor, the switch elements for each phase are 
controlled to apply power to its respective phase 
windings from a selected turn-on angle to a selected 
turn-off angle. The maximum difference in low speed 
operation between the turn-on angle and the turn-off 
angle for each phase is no greater than the angle sub­
tended by adjacent stator poles as measured from the 
geometric center of the stator. For high speed operation, 
only the windings of the first phase are energized, and 
the difference between the turn-on angle and the turn-­
off angle for the first phase windings is greater than 
the angle subtended by adjacent stator poles.

Abstract: A digital synthesizer includes an input transducer (101) for 
accepting input signals from a musician representing at least 
the desired fundamental pitch and timbre. The synthesizer has 
timbre storing circuitry for storing data representing a plu­
rality of selectable timbres, including relative pitch data 
for a plurality of sets of partials and a plurality of sets 
of amplitude data, the partials and the amplitudes being inde­
pendently selectable. Waveform determining circuitry deter­
mines sequential values of the musical waveform in real time 
from the timbre data, from the timbre selected by the musi­
cian, and from the pitch selected by the musician. The wave­
form determining circuitry includes a first adder (201) for 
additively determining the phase of each partial of the se­
lected timbre and is responsive to the relative partial 
pitch data to determine that phase. It also includes a se­
cond adder (204) for summing the magnitudes of all the par­
tials for the selected timbre at each predetermined time 
interval to generate the magnitude of the musical waveform 
at that instant.

Abstract: Die Erfindung betrifft ein Flüssigkeitssystem für eine durch 
einen Turbolader (2) aufgeladene Brennkraftmaschine (1), wo­
bei der Turbolader über eine Vorlaufleitung (4) und eine 
Rücklaufleitung (6) mit dem Kühlkreislauf der Brennkraftma­
schine verbunden ist und im Betrieb der Brennkraftmaschine 
eine Zwangsumlaufkühlung erfolgt, sowie das Kühlsystem einen 
Ausgleichsbehälter (8) für die Kühlflüssigkeit aufweist.  
     Um sicherzustellen, daß die Kühlung des Turboladers nach dem 
Abschalten der Brennkraftmaschine ohne Zuhilfenahme einer 
nachlaufenden Umwälzpumpe mit einem hohen Wirkungsgrad er­
folgt, wird erfindungsgemäß vorgeschlagen, daß sich in der 
Vorlaufleitung des Turboladers ein Rückschlagventil (5) be­
findet und die Rücklaufleitung des Turboladers verzweigt aus­
gebildet ist, in eine erste Leitung (10), die oberhalb des 
Kühlmittelspiegels (12) in den Ausgleichsbehälter mündet sowie 
eine zweite Leitung (11), die unterhalb des Kühlmittelspiegels 
in den Ausgleichsbehälter mündet und ein Rückschlagventil (7) 
enthält.  
     Bei dem erfindungsgemäßen Kühlsystem führt ein Abschalten der 
Brennkraftmaschine dazu, daß das Kühlmittel im Turbolader auf­
geheizt wird, verdampft und die dampfförmige Phase die flüs­
sige Kühlmittelphase mehr oder weniger in den Ausgleichsbe­
hälter ausstößt. Dies führt zu einem Druckunterschied am Rück­
schlagventil der Vorlaufleitung, so daß Kühlflüssigkeit aus 
dem System durch die Vorlaufleitung (4) zum Turbolader (2) 
nachläuft. Der zyklische und schubweise Vorgang endet erst, 
wenn das Lager des Turboladers auf Kühlmittelsiedetemperatur 
abgekühlt ist.

Title: Polymer coated object, eg roller, pressure cushion etc, with localized adhesion and procedure for its manufacture
IPC: D21F3/02
Filed: 1991-09-24
Abstract: The invention relates to a procedure for manufacturing an object coated with polymer, in particular with elastomer, on a curved and/or flat surface, for example a roller, pressure cushion, pressing shoe, heating/cooling mat, lubricated bearing segment. The invention is principally characterised in that the polymer, in particular elastomer, is produced in a localised manner without adhesion to the coated and/or uncoated object surface and is expediently lifted off there from the coated and/or uncoated object surface. The invention also comprises an object coated with a layer of polymer, in particular a layer of elastomer, on a curved and/or flat surface, for example a roller, pressure cushion. The object according to the invention is principally characterised in that on the coated and/or uncoated object surface, for example the circumferential surface of a roller, pressure cushion, there is arranged at least one localised adhesion inhibitor or preventer or reducer, the region of which may have a feed line or discharge line for gaseous or liquid medium, in particular air. According to the pressure difference between inlet and outlet, the hollow space produced will vary in size and this in turn results in a corresponding throughflow of medium, or results in a different outlet rate, if the hollow spaces are connected to the surface by small openings, which is used advantageously in the case of lubricated bearings or in the case of pressing shoes or coating and moistening rollers. Even in the case of heating and cooling plates or rollers, the proximity of the medium to the surface and the ability to regulate the throughflow rate lead to applications in paper, plastics, pulp, printing and textile machine engineering. According to the pressure difference, corresponding pressure and force of reaction can be exerted in at least one region of the interconnected hollow spaces and, in the case of counter-pressure, by elements in contact with the surface, such as for example a printing plate, counter-roller, screen cloth. This effect is advantageous in the case of pressure cushions, pressing plates, wide nip rollers. The invention is based on the object of permitting hollow-space shaping, or profile shaping, or varied heat transfer contact by the elevations on the coating surface in a simple and inexpensive way by simple insertion of strips or preformed inserts or films or the like or else a coating or layer of lacquer or the like on the coated and/or uncoated object surface in an easily reproducible and also multi-layered way. <IMAGE>
