Title: Massively distributed simulation engine
IPC: G06F11/25
Filed: 1989-03-22
Abstract: A simulation engine for logically simulating a logic 
network, which is divided into several levels of 
hierarchy. At the lowest level is a logic chip which 
has stored in an instruction memory a sequentially 
executed program of logical operators and operand 
addresses. The operand addresses refer to an input 
memory of the chip. The next highest level is the 
logic unit, on one circuit board, comprising a 
plurality of such logic chips. Each of the logic chips 
of the unit has its input memory receiving the same 
data from an input bus and a local bus and provides as 
its output one of the bits of an output bus and one of 
the bits of the local bus. At the next level, called a 
cluster, several logic units have their input and 
output buses interconnected by a plurality of switch 
units. All the logic chips of the several logic units 
operate in parallel with the exchange of data through 
the switch units. Several clusters can be combined 
into a super cluster by connecting together two or more 
sets of switch units.

Patent EP-0342861-A3 (EP)
Title: Smoothing apparatus for independently clocked networks
IPC: H04J3/06
Filed: 1989-05-11
Abstract: A method and apparatus are disclosed for 
preserving a minimum or maximum interpacket gap length 
in an independently clocked data network, typically one 
following the ANSI-FDDI standard. A smoother is placed 
downstream of each elastic buffer in the network. The 
smoother detects the occurrence in an arriving stream 
of bytes of short preambles, i.e., those having fewer 
than a threshold number of idle bytes, and inserts some 
number n a  additional idle bytes into such preambles. 
Subsequently arriving bytes are delayed by n a  byte 
clock periods by, in a preferred embodiment, storing 
them in a FIFO sequence of registers. In order to be 
available for lengthening other short preambles when 
they arrive, the smoother also detects the arrival of 
long preambles, i.e., those having more than the 
threshold number of idle bytes, and deletes a number n d  
idle bytes from such long preambles. Deletion is 
accomplished in the preferred embodiment by reducing 
the delay of the stream, which in turn is accomplished 
by reducing the length of the FIFO sequence of delay 
registers by n d  registers. Idle bytes which may have 
been temporarily stored in delay registers which are 
no longer part of the FIFO sequence are discarded. 
This reduces the extension of the smoother and makes it 
available for inserting idle bytes into subsequently 
arriving short preambles. The method and apparatus can 
be expanded to provide several extended states at each 
of several different thresholds. It can also be 
applied in a network requiring a maximum interpacket 
gap length by providing a normal state and one or more 
contracted states.

Patent EP-0359394-A3 (EP)
Title: Extraction and insertion for a leader block of a tape cartridge
IPC: G11B15/67
Filed: 1989-08-10
Abstract: A tape transport for a leader block tape 
cartridge (10) has a threading mechanism including a 
threader pin (50) for engaging the leader block (16) 
and extracting it from the cartridge after it has been 
loaded into the transport adjacent a first end of a 
tape path. The threading mechanism pulls the leader 
block along the tape path pas a read/write head (52), 
and inserts the leader block into a take-up hub (60) 
adjacent a second end of the tape path during a 
threading operation. During a rewinding operation, 
the threading mechanism extracts the leader block from 
the take-up hub, pulls the leader block past the 
read/write head and inserts the leader block back into 
the cartridge. A first guide assembly (70, 42 a ) 
adjacent the first end of the tape path engages and 
guides the leader block to ensure proper insertion 
thereof back into the cartridge during the rewinding 
operation. A second guide assembly (72, 42 b ) 
adjacent the second end of the tape path engages and 
guides the leader block to ensure proper insertion 
thereof into the take-up hub during the threading 
operation. This accommodates the tolerance variations 
in the positions of the cartridge and take-up hub, and 
in the dimensions of the cartridge, leader block, 
take-up hub and threader pin which can otherwise lead 
to failures in the aromatic insertion of the leader 
block into the cartridge and/or take-up hub.

Title: Cmos integrated circuit having improved isolation
IPC: H01L21/8238
Filed: 1989-08-24
Abstract: A p-type tub in a CMOS integrated circuit is isolated from the 
adjacent n-type tub by means of a field oxide (65) having a p-type 
channel stop region (66) formed by a boron ion implant. The depth 
of the ion implant is selected so that the peak of the boron 
concentration is located immediately under the field oxide region 
that is subsequently grown. In addition, the implant is allowed to 
penetrate into the active device regions, producing a retrograde 
boron concentration in the n-channel region. This technique 
simultaneously improves device isolation and n-channel transistor 
punch-through characteristics, allowing the extension of CMOS 
technology to sub-micron device geometries.
Patent EP-0357411-A3 (EP)
Title: Controlled-inductance regulator for switching power supplies
IPC: H02M7/06
Filed: 1989-08-31
Abstract: A post secondary magnetic amplifier circuit 
for operation at frequencies at or above 100 kHz with 
minimal losses is described. A magnetic amplifier is 
used to control the post-secondary current to an LC 
filter in which the magnetic amplifier is constructed 
using an non-nickel core material such as ferrite having 
a very narrow B-H operating curve (flat loop) in which 
the remanence (residual magnetism) is below 1000 gauss. 
The magnetic amplifier then operates as a controlled 
inductance so that saturation is approached slowly.

Abstract: The  car L and  car M genes of  Streptomyces 
thermotolerams  have been isolated and used to construct 
recombinant DNA expression vectors. The  car L and  car M 
encode activities required for the biosynthesis of 
macrolide antibiotics. These genes have been shown to 
complement  Streptomyces fradiae  mutants which lack the 
ability to produce the antibiotic, tylosin. The  car L 
and  car M genes can be used not only to construct 
recombinant cells with increased ability to produce 
macrolides but also to construct recombinant cells with 
the ability to produce novel antibiotic compounds.
Patent EP-0369682-A3 (EP)
Title: Efficient coding method and its decoding method
IPC: H03M7/30
Filed: 1989-11-09
Abstract: An efficient coding method of coding video 
signals, speech signals and the like at a lesser amount 
of bit rate and a decoding method of performing inverse 
transformation thereof for digital transmission or 
recording. In accordance with the present invention, in 
the coding method, a block made up of a plurality of 
input data for an input signal is used as an encoding 
unit, a maximum SX and a minimum SN of predictive errors 
corresponding to differences between the input data of 
the block and its prediction value are computed, a 
predetermined value larger than a data (SX - SN) is used 
as a divisor data OU, modulos E obtained by dividing the 
respective input data of the block by said divisor data 
OU are encoded, and additional codes including predictive 
error information on said data SX, SN and OU as well as 
encoded codes of said modulos E are both transmitted. 
In the decoding method, information (the maximum SX and 
minimum SN of predictive errors) on the predictive error 
presence range and the divisor data OU as a remainder 
are obtained directly or indirectly on the basis of the 
transmitted additional codes. As a result, offsets 
(integer multiple of the divisor data OU) obtained through 
divisor in the coding operation can be rightly and 
uniquely determined in the decoding operation and when 
the offsets are added to the transmitted modulos E, the 
 
 
input data can be perfectly reproduced. That is, any 
anomaly errors can be totally eliminated.
