IPC: H01L29/812
Filed: 1986-09-04
Abstract: Sperrschicht-Feldeffekt­
transistor mit einem Drainbereich (2), einem Sourcebereich (3) 
und einer Gateelektrode (9) zur Beeinflussung eines Kanal­
gebietes (8). Die dem Drainbereich zugewandte Kante (12) der 
Gateelektrode (9) kann geringfügig näher, oder um ein Maß x weiter vom 
Drainbereich (2) als die dem Drainbereich zugewandte äußere Kante (13) 
des Sourcebereiches (3) angeordnet werden, oder mit ihr zusammenfallen. 
Der Abschnürbereich (11), der durch die Raumladungszone (10a, 10b) 
definiert ist, muß im Betriebszustand des Transistors im Kanalgebiet (8) 
zwischen dem Sourcebereich (3) und dem Drainbereich (2) liegen. Der 
Abstand des Abschnürbereiches (11) zur äußeren Kante (13) des 
Sourcebereiches (3) stellt die effektive Kanallänge (L geff ) dar, die so 
klein wird, daß eine Erhöhung der Elektronengeschwindigkeit im Kanal 
erzielt wird.

Abstract: A microform reader for reading microfilm filmed at a 
reduction of about 200 times forms an image of a selected 
page on the microform on a linear solid state sensor which 
scans down the image of the page to produce a line-by-line 
or video-type representation of the page for transmission to 
a remote location. Selected lines of the sensor output are 
analysed to provide a determination of image parameters 
and enable the image-forming system to be adjusted to 
improve the transmitted image quality.  
     Thus each filmed page carries at its head a registration 
target of well defined shape such that a selected scanned line 
yields precise information as to the X-Y location of the page. 
Also selected pages include a focussing target including a 
pattern carrying a black/white discontinuities. Analysis of the 
scanned line representing the discontinuities gives a mea­
sure of the accuracy of focus enabling appropriate adjust­
ment to be made automatically.

Title: Small table-clock case
IPC: G04B37/00
Filed: 1987-06-27
Abstract: The invention relates to a case consisting of a front section (1) and a cover section (2) which is moveable relative to the front section and can be locked in at least two positions of rest (I, II); changing the relative position of the two parts of the case (1, 2) operates a switching mechanism, for example for activating the alarm function of the clock. It is advantageous to provide a third position of rest (III) in which the battery holder (39) is accessible, thus facilitating battery changing, which is a complicated procedure in known clocks, requiring opening and reassembling of parts of the case. <IMAGE>

IPC: H04N7/16
Filed: 1987-10-17
Abstract: A cable television channel selector/descrambler 
enables the full capabilities of a cable-ready video 
appliance (e.g., television set or VCR) to be used in 
conjuncton with a cable television system providing 
unscrambled channels and scrambled premium channels. 
A broadband cable signal containing a plurality of 
television signal channels having different 
frequencies is passed through a filter to produce a 
modified cable signal having one of the signal 
channels removed therefrom. The broadband cable 
signal is input to a tuner for selectively tuning only 
to scrambled signal channels contained in the 
broadband cable signal. The tuner is tuned to a 
scrambled signal channel to be viewed by stepping 
through the scrambled signal channels accessible by 
the tuner until the desired signal channel is reached. 
A scrambled signal tuned by the tuner is descrambled 
and remodulated to convert it to the frequency of the 
signal channel removed by the filter in producing the 
modified cable signal. The re-modulated descrambled 
signal is combined with the modified cable signal to 
form a composite signal for input to a video 
appliance. The composite signal contains all of the 
original unscrambled channels together with the 
selected premium channel which has been descrambled.

IPC: G06Q10/06
Filed: 1987-04-08
Abstract: A method and apparatus for optimizing resource allocations is disclosed 
which utilizes the Karmarkar algorithm to proceed in the interior of the solution 
space polytope. At least one allocation variable is assumed to be unconstrained 
in value. Each successive approximation of the solution point, and the 
polytope, are normalized such that the solution point is at the center of the 
normalized polytope using a diagonal matrix of the current solution point. The 
objective function is then projected into the normalized space and the next step 
is taken in the interior of the polytope, in the direction of steepest-descent of 
the objective function gradient and of such a magnitude as to remain within the 
interior of the polytope. The process is repeated until the optimum solution is 
closely approximated.  
     The resulting algorithm steps are advantageously applied to the phase 
one problem of obtaining a starting point, and to the dual problem, where the 
free variable assumption produces unexpected computational advantages.

IPC: B41J2/14
Filed: 1987-07-01
Abstract: An air-assisted drop-on-demand ink jet head l0 
has a single compartment ink chamber l4 and is designed 
for operation over a wide range of ink drop repetition 
rates, including extremely high repetition rates, such 
as twenty kilohertz. The components included in the ink 
jet head have natural resonance frequencies which are 
greater than the desired maximum drop generation 
frequency of the ink jet head. In addition, the natural 
frequency of each of the components of the ink jet head 
are sufficiently different from one another to prevent 
intercoupling. Ink is supplied to the ink chamber l4 
via a supply inlet passageway 38 which has a 
cross-sectional area which is sized large enough to 
allow the supply of ink to the ink chamber. Yet, this 
area is small enough so that the natural frequencies of 
ink in the ink inlet do not significantly alter drop 
generating pressure pulses in the ink chamber l4.

IPC: C08G61/12

Abstract: Friedel Crafts preparation of arylene ether ketone 
polymers with an exceptionally high degree of isomeric 
purity and freedom from by-products can be achieved by 
adding to the Lewis acid reaction system a protic 
controlling agent selected from ROX, water, RCOOX, 
RSO₃X, and ROY, wherein R is organic, X is hydrogen or 
metal, and Y is metal. Contrary to conventional expec­
tation, the protic agent does not significantly acylate 
or alkylate the polymer, and agents of relatively low 
molecular weight, e.g. benzoic acid, can be selected to 
produce dispersions of the resulting polymers. The 
controlling agent also apparently acts to maintain the 
polymer in solution until a desired molecular weight is 
reached.

By means of an excentric device, the connecting rods of which are articulated on the one hand on the excentric device and on the other hand on the bracket arms, the bracket arms, with the passenger carriers, can be pivoted in alternating high and inclined positions about axes tangential to the central axis. The excentric device has, below the bracket arms, two turntables arranged coaxially above one another and concentrically with the central axis, which are rotatable about the central axis together and independently of the bracket arms, the upper turntable being pivotable into an inclined position relative to the lower turntable. The connecting rods are articulated on a catch ring which is supported coaxially on the upper turntable and is mounted freely rotatably. <IMAGE>

IPC: H01L21/677
Filed: 1988-02-08
Abstract: A tactile pick includes a base and a lever 
attached beneath the base by a pivot. A load 
sensing device including a strain gauge is located 
between the base and the portion of the lever on 
one side of the pivot; the portion of the lever on 
the other side of the pivot is adapted to receive a 
semiconductor wafer. Rotation of the lever about 
the pivot induced by the weight of a wafer causes 
an actuator to depress a flexible member on which a 
strain gauge is mounted. The output signal of the 
strain gauge is processed by a controller to provide 
an output signal which varies monotonically with 
the magnitude of the weight placed on the wafer 
receiving portion of the lever. The pick is employed 
in connection with the wafer transport system which 
transfers wafers from a cassette to the pick lever.
