Patent EP-0254128-A3 (EP)
IPC: H01J37/02
Filed: 1987-07-07
Abstract: Zur Inspektion und Vermessung feinster Strukturen in 
der Mikroelektronik und der integrierten Optik werden 
immer häufiger Rastermikroskope eingesetzt. Um unver­
zerrte und hochauflösende Abbildungen der im allge­
meinen aus verschiedenen Materialkomponenten bestehen­
den Proben zu gewährleisten, müssen Aufladungen nicht­
oder schlechtleitender Oberflächen durch den abtasten­
den Primärstrahl vermieden werden. Es wird deshalb vor­
geschlagen, die Probe mit Korpuskeln abzutasten, deren 
Energie oberhalb der höchsten Neutralpunktenergie aller 
Oberflächenmaterialien liegt. Die durch den Primär­
strahl aufgebrachten negativen Ladungen werden durch Be­
strahlung der Probe mit UV-Licht reduziert bzw. bei 
genügend hoher Strahlungsintensität vollständig abge­
baut.

Title: Stepper motor shaft position sensor
IPC: H02P8/36
Filed: 1988-08-24
Abstract: A stepper motor shaft position sensor differentiates 
the current provided when the stepper motor is excited as 
by a step command voltage. The differentiated current is, 
in effect, a signature indicative of whether or not the 
motor shaft has taken a step. If the differentiated 
current falls below a predetermined level within a pre­
determined interval the motor shaft has taken a step as 
indicated by a sensor output at a predetermined logic 
level. Otherwise, the sensor output is at another 
predetermined logic level indicating that a step has not 
been taken and the motor is in a stalled condition. The 
sensor output is applied to a utilizing means which provides 
a continuous verification of the stepper motor shaft position.

Title: Method and apparatus for performing timing correction transformations on a technology-independent logic model during logic synthesis
IPC: H03K19/00
Filed: 1989-06-01
Abstract: A computer program is disclosed providing a sequence 
of automated logic synthesis routines having three 
phases. Phase I identifies an estimated critical path 
by assuming optimum allocation within a "best-fit" 
preliminary assignment of the technology to a 
technology-independent model, and optimizes the 
estimated model for speed. Phase II provides a 
technology-legal model, and ends by calculating the 
actual timing provided by the technology-legal model. 
Phase III uses self-limiting routines, and routines 
that are unlikely to produce technology violations, to 
fine tume the production and performance 
characteristics of the legal model.

Title: Semiconductor non-volatile memory device
IPC: G11C16/14
Filed: 1989-05-12
Abstract: This invention relates to a semiconductor non-­
volatile memory device, in which plural data storage 
parts are connected in series between the source region 
and drain region. In such constitution, when integrat­
ing the semiconductors, the relative area occupied by 
the selection gate, separation gate, source region and 
drain region of the area of the data storage parts may 
be drastically reduced, and the degree of integration 
of semiconductor non-volatile memory device can be 
dramatically enhanced. This invention also comprises 
means for setting the semiconductor substrate in 
depletion state by sequentially varying the gate 
potential of the plural data storage parts and trans­
ferring the electric charges sequentially. By this 
means for transferring electric charges, data write 
errors may be securely prevented.

Title: Bandwidth reduction system for television
IPC: H04N7/015
Filed: 1989-06-22
Abstract: An HDTV picture is transmitted in a 625/50 MAC channel using 
bandwidth reduction techniques. In an 80ms coding branch motion 
compensation is provided by generating motion vectors for each block 
of the picture. The motion estimation is performed on a 
downfiltered and subsampled signal, and peaks in the phase 
correlation surface are estimated by an inverted-V interpolator 
function. Vectors are assigned to the blocks by determining the 
assignment error over both a field period and a frame period and 
summing the two. A "menu" of eight vectors is available for each 
block.  
     To assist compatibility, samples are repositioned before 
transmission by calculating the average motion per field for each 
block, rounding the resultant to the nearest even number of pixels 
and picture lines per field period, and displacing the samples in 
dependence upon the resultant displacement value and upon the field 
number from which the sample is derived. Furthermore, a filter is 
selectively included to provide an attenuating dip centred 
on 12.5 Hz.

Title: Method for forming a non-planar structure on the surface of a semiconductor substrate
IPC: H01L21/762
Filed: 1989-03-24
Abstract: A method for increasing the width of a transistor 
includes first forming a nitride cap (14) over the substrate 
(10) and then forming trenches (24) and (26) on either side 
of the cap (14) and having tapered sidewalls (28) and (30). 
A conformal layer of nitride (32) is formed over the 
substrate and then anisotropically etched to form sidewall 
layers (34) and (36). Field oxide is grown in the trenches 
with birds beaks (42) and (44) extending upward under the 
sidewall layers (34) and (36). A portion of the 
sidewalls (28) and (30) of the trenches remain such that the 
overall surface area between the edges of the birds beaks 
(42) and (44) is increased. A layer of strip oxide is then 
grown on the substrate to provide rounded edges (47) and 
(49). The strip oxide is then removed by a fifty percent 
over etch to cause the birds beaks (42) and (44) to recede, 
thus further increasing the surface area. The gate electrode 
of a transistor (54) can then be disposed thereacross, thus 
increasing the width of the transistor for a given silicon 
surface area in the initial material.

Filed: 1990-02-20
Abstract: The machine useful in roofing 
applications, comprises a shoe (22), which

into the machine, is used to drive a fastener, such as a 
screw (18), through a batten, through the sheet and through 
any underlying sheets of roofing materials, into an 
underlayment. The screw gun is mounted to the shoe (22), 
which is mounted to a base (20) for relative movement between 
the shoe (22) and the base (20). The shoe (22) is biased 
gravitationally, and by a spring (380), so as to urge the shoe (22) 
toward the batten while the batten is being fastened. A 
canister (26), which is mounted to the base (20), is arranged to 
receive the batten in a coil, which tends to expand when 
released, and to supply the batten to the shoe (22), through 
an outlet of the canister (26).
