Patent EP-0256777-A3 (EP)
IPC: B29C49/06
Filed: 1987-08-05
Abstract: Method and apparatus for injection blow molding 
hollow articles from polyethylene terephthalate (PET) 
resin utilizing a hollow core rod on which a parison is 
first injection molded, and subsequently stretched and blown 
to form the hollow article. Fluid is continuously circulated 
through the hollow core rod to promote cooling of the plastic 
and insure the production of hollow articles that are trans­
parent and of high quality from a clarity standpoint. A 
separate supply of blow air is provided at the blow molding 
station so as not to interfere with the continuous flow of 
coolant through the hollow core rod.

Title: Digital switching network for circuit and packet switching, and coupling device therefor
IPC: H04Q11/04
Filed: 1988-01-22
Abstract: A digital switching network is disclosed in which paths can be preset from any inlet to any outlet either for circuit-switched connections or for packet-switched messages (packets), as required. At any point in time, the paths preset for the packet-switched messages form a network whose nodes lie in the switching facilities of the switching network. The switching facilities contain the functional units required to switch each data packet on the path preset for it. This makes it possible to dynamically divide a single switching network into a circuit-switching network and a packet-switching network as required.

Title: Method and apparatus for character recognition systems
IPC: G06V10/98
Filed: 1988-11-22
Abstract: The present invention employs a method of choosing 
between the output of two different character 
recognition systems to improve the rate at which 
characters are recognized, without significantly 
increasing the number of undetected substitution 
errors. If the first recognition system cannot 
recognize a character, a random probability generator 
is used to determine whether to use the output of the 
second recognition system, or alternatively to generate 
a reject character.

IPC: H01L27/112
Filed: 1988-12-14
Abstract: Electrically-programmable low-impedance anti-fuses 
are disclosed having capacitor-like structure with very low 
leakage before programming and a low resistance after 
programming. The electrically-programmable low-impedance anti-­
fuses (13, 15) of the present invention include a first conductive 
electrode (12a, 12b) which may be formed as a diffusion region in a 
semiconductor substrate (10) or may be formed from a semiconductor 
material, such as polysilicon, located above and insulated from 
the substrate. A dielectric layer (14), which, in a preferred 
embodiment includes a first layer of silicon dioxide (16), a second 
layer of silicon nitride (18) and a third 
layer of silicon dioxide (20), is 
disposed over the first electrode. A 
second electrode (22a, 22b) is formed 
over the dielectric layer from a semiconductor material such as 
polysilicon, or a metal having a barrier metal underneath. At 
least one of the two electrodes of each anti-fuse is highly-doped 
or implanted with arsenic such that high concentrations of 
arsenic exist at the interface between the electrode and the 
dielectric layer. This arsenic will combine with other material 
and flow into the anti-fuse filament after programmed to form a 
low resistance controllable anti-fuse link. Circuitry is 
provided which allows the anti-fuse of the present invention to 
be programmed by application of a suitable programming voltage to 
input-output pins of the integrated circuit containing the anti-­
fuse. Where more than one anti-fuse is to be programmed using 
the programming voltage applied at the input-output terminals, 
other additional input-output terminals may serve as address 
inputs to specify the anti-fuse to be programmed.  
     In another embodiment of the present invention a 
programmable read-only memory array comprised of memory cells 
including a anti-fuse in combination with a single transistor. 
X-address and Y-address decoder circuits are provided to both 
program and read the contents of any selected memory cell in the 
array.

Patent EP-0352725-A3 (EP)
Title: Numerical controller for machining a non-circular workpiece
IPC: B24B19/12
Filed: 1989-07-25
Abstract: When machining cams with the same profile data, finished 
shape errors tend to increase as the diameter of a grinding 
wheel decreases. In order to keep the finished shape errors 
within a tolerance, the profile data used for machining must 
be renewed with new profile data corresponding to the present 
diameter of the grinding wheel. In the disclosed numerically 
controlled cam grinding machine, optimum wheel diameters, at 
which new profile data must be calculated, are decided automatically. 
The numerical controller calculates the marginal 
diameters which require renewal of profile data based upon 
the machining tolerance when a new grinding wheel is attached 
to the wheel head. After that, the numerical controller 
calculates new profile data from the marginal wheel diameter 
and lift data, when the present wheel diameter reaches into 
one of the marginal wheel diameters. The old profile data is 
renewed with the newly calculated profile data corresponding 
to the marginal wheel diameter.

Title: Harmonic speech coding arrangement
IPC: G10L19/02
Filed: 1989-03-31
Abstract: A harmonic coding arrangement where the magnitude spectrum of the input speech is modeled at the analyzer (120) by a relatively small set of parameters and, significantly, as a continuous rather than only a line magnitude spectrum. The synthesizer (160), rather than the analyzer, determines the magnitude, frequency, and phase of a large number of sinusoids which are summed to generate synthetic speech of improved quality. Rather than receiving information explicitly defining the sinusoids from the analyzer, the synthesizer receives the small set of parameters and uses those parameters to determine a spectrum, which, in turn, is used by the synthesizer to determine the sinusoids for synthesis.

Title: Error detection and correction for a data storage system
IPC: H03M13/00
Filed: 1989-10-06
Abstract: Occurrence of uncorrectable errors in a stored 
sector of data which includes a data block, an error 
checking and correcting (ECC) block and an error 
detecting (CRC) block is detected. ECC logic is 
connected to a data bus and responsive to the ECC 
block in the sector, for generating an error polynomial 
identifying a location and a value for correctable 
errors in the sector. CRC logic is connected to the 
data bus and responsive to the CRC block in the sector 
for generating a syndrome identifying detected errors 
in the data block. An evaluation logic circuit is 
included that is coupled to the ECC logic and the CRC 
logic and responsive to the error polynomial and the 
syndrome for generating an uncorrectable error signal 
if the detected errors do not match the correctable 
errors. The error checking and correcting code is a 
Reed-Solomon code as in the X3B11 standard. Likewise 
the CRC code is a Reed-Solomon code as in the X3B11 
standard. The evaluation logic implements a reverse 
CRC generation polynomial having a plurality of terms 
in the same order as the error polynomial. Detection 
logic receives the plurality of terms of the error 
polynomial, generates an estimated CRC syndrome based 
on the reverse CRC generation polynomial, and generates 
 
 
the uncorrectable error signal if the estimated CRC 
syndrome is not equal to the generated CRC syndrome.
