Title: Character string recognition system
IPC: G06V30/262
Filed: 1989-01-18
Abstract: Recognition character candidates and their similarities 
for each character obtained by a character 
recognition section from an input character string are 
stored in a first recognition result memory (23), and 
recognition character candidates obtained by rotating 
the corresponding characters through 180 degrees and 
their similarities are stored in a second recognition 
result memory (47). Address pointers for accessing 
the first and second recognition result memories are 
stored in an address pointer memory (45). The first 
recognition result memory is accessed in accordance 
with the address pointers read out from the address 
pointer memory in an ascending order, and the second 
recognition result memory is accessed in accordance with 
the address pointers read out from the address pointer 
memory in a descending order. Coincidences between 
recognition candidates read out from the first and 
second recognition result memories and character strings 
of dictionary words read out from a dictionary memory 
(33) are computed by a coincidence computing section 
(31). A recognition result of the input character 
string is obtained based on the coincidences.

Title: Alignment of lithographic system
IPC: G03F9/00
Filed: 1989-05-18
Abstract: A method for lithographic alignment utilized in the manufacture of 
integrated circuits is described. The procedure includes an initial calibration 
through the lens system to expose a calibration material in a diffraction grating 
pattern. An interference pattern is produced above the grating with intersecting 
laser beams. By adjusting the path and/or phase of these beams the interference 
pattern is aligned with the diffraction pattern to establish a calibration point 
corresponding to a reference intensity in the intensity of the diffracted light. A 
wafer to be exposed is then placed in the exposure tool and is aligned by 
observing the diffraction pattern from a diffraction grating fiducial mark induced 
by the calibrated interference pattern.
Patent EP-0343988-A3 (EP)
Title: Data processing apparatus with selective instruction prefetching
IPC: G06F9/38
Filed: 1989-05-25
Abstract: In a microcomputer system comprising a microprocessor and a cache 
subsystem and operable in a pipelined mode, there is potential 
incompatibility between pipelined operations and dynamic bus sizing as 
the cache subsystem operates with a fixed size data width and dynamic 
bus sizing allows the system to operate with devices of differing data 
width. This incompatibility is accommodated by the present system by 
defining certain addresses as cacheable addresses and other addresses 
as non-cacheable addresses and ensuring that addresses of devices of 
data width different from the cache data width are non-cacheable. An 
address decoder provides a control signal indicating whether or not a 
generated address is within the cacheable range. This control signal 
controls a next address signal applied to the microprocessor, which 
signal allows the processor to proceed to a following cycle prior to 
the end of the current cycle. Whenever a non-cacheable address is 
detected, the next address signal is suppressed.

Patent EP-0388951-A3 (EP)
IPC: H04L12/54
Filed: 1990-03-22
Abstract: In a high-speed packet multiplex communication 
network including a transmission line with a 
predetermined bandwidth and accommodating a plurality of 
information sources, the sources having various packet 
delivery rates over a range of between a peak rate and a 
lower rate than an average rate and demanding various 
transport performances, the sources are preliminarily 
classified into a plurality of types according to 
transport performances required and different 
transmission priorities are assigned to the different 
types, respectively. Bandwidths of sources of first 
priority and second priority are determined ones 
corresponding to the peak rate and the average rate, 
respectively. A virtual bandwidth may be calculated for 
the second priority source as a value between the peak 
and average rates. In response to connection requests 
from the sources, each of the connection requests is 
admitted when a bandwidth defined by the priority of 
each source is accepted in a residual bandwidth of the 
predetermined bandwidth, and the packets from the 
source of the first priority are preferentially 
transmitted to the transmission line, packets of the 
second priority source are transmitted when packets of 
the first priority source are absent. Thus, high 
bandwidth efficiency is insured while the high transport 
performance of the first priority source is maintained.

Title: Device for testing and/or measuring a test object
IPC: G01N27/90
Filed: 1990-03-26
Abstract: Device for testing and/or measuring a test object with a 
signal transmission being arranged between a movable trans­
ducer/sensor (1) and stationarily located equipment, for ex­
ample an electric cabinet. The transducer is in the form of 
a carriage or placed on/in a carriage which moves, for exam­
ple backwards and forwards across a test object (2). By 
mounting a conductor (16) in parallel with the path of move­
ment of the transducer and allowing this stationary conduc­
tor to constitute a winding on a transformer ring-core (13), 
placed on the carriage and thus being movable along the con­
ductor (16), signals can be transmitted without galvanic 
signal connection between the carriage and, for example, 
stationary equipment. A consequence of this signal transmis­
sion is that the transducer (1) can move as a so-called 
shuttle across, for example, a hot steel strand (2) with no 
other means of driving than its own kinetic energy, which 
may, for example, be supplied by means of compressed air im­
pulses when the transducer is positioned outside near the 
edges of the steel strand. The signal transmission can ad­
vantageously be made bidirectional, and one field of appli­
cation is the so-called eddy current testing, in which the 
signal transmission problem often constitutes a greatly lim­
iting factor. In simplified terms the signal transmission 
device can be regarded as a transformer with a movable wind­
ing, in its simplest embodiment.

Title: Capillary electrophoretic device employing structure permitting electrical contact through ionic movement
IPC: G01N27/447
Filed: 1990-06-01
Abstract: A capillary tube (12) has a structure (14) in its wall 
that permits ions to flow but no substantial amount of 
electrolyte to move therethrough. The structure 
therefore permits electrical contact between electrolyte 
inside the tube and the outside environment without 
diluting the electrolyte. The structure (14) forms only 
a small part of the tube side wall so that the tube (12) 
retains its structural integrity and can be used in 
electrophoresis without requiring structural support. 
In the preferred embodiment, the structure (14) is 
formed by drilling a hole (102) in the side wall, 
filling the hole with glass powder and fused silica 
(106) and heating the mixture to form a frit structure 
to plug the hole (102). The frit structure permits ions 
to flow but substantially no electrolyte to move 
therethrough. During electrophoresis, a potential is 
applied between one end (12a) of the tube (12) and the 
structure (14)  via  an electroyte (18). Electrophoretic 
smaples exit undiluted from the other (12b) end of the 
tube (12) and can be continuously collected, such as on 
top of a moving plate (60).

Abstract: This invention relates to a capacitance 
standard (10) for use with capacitance sensitive probes (P). 
The standard comprises a capacitor having a pair of 
spaced plates (20,21) and a dielectric (25) positioned 
therebetween. A shield attached to one of the 
plates forms an enclosure around the other plate to 
essentially shield the capacitor. The capacitance 
standard is therefore not affected by outside 
electrical fields and an accurate, reproducible 
capacitance value is provided.
