Patent EP-0400892-A3 (EP)
IPC: C07C45/46
Filed: 1990-05-23
Abstract: A method is provided for the preparation of ibuprofen by 
carbonylating 1-(4′-isobutylphenyl)ethanol (IBPE) with carbon 
monoxide in an acidic aqueous medium, e.g. containing at least 10% of 
water based on the weight of IBPE initially added, at a temperature of 
at least about 10°C and a carbon monoxide pressure of at least about 
500 psig, and in the presence of (1) a catalyst complex consisting 
essentially of a palladium compound in which the palladium has a 
valence of zero to 2 and is complexed with at least one monodentate 
phosphine ligand miscible with the organic phase of the reaction 
medium, the phosphorus/palladium mole ratio in said palladium compound 
and ligand being at least about 2:1 when the palladium/IBPE mole ratio 
is such that palladium=1 and IBPE=10,000 or more; (2) dissociated 
hydrogen ions from an acid which is substantially completely ionizable 
in dilute aqueous solution such that the mole ratio of hydrogen ions 
to IBPE added to the reaction zone is at least about 0.15; and, (3) 
dissociated halide ions such that the mole ratio of halide ions to 
IBPE added to the reaction zone is at least about 0.15. 
Advantageously, a hydrogen halide is the source of hydrogen ions and 
halide ions. The carbonylation is preferably integrated with a method 
of producing IBPE from isobutylbenzene wherein the latter compound is 
subjected to Friedel-Crafts reaction with an acetylating agent to 
produce 4-isobutylacetophenone, which is then reduced with hydrogen in 
the presence of a hydrogenation catalyst, or with a reducing agent 
containing available hydrogen, to obtain IBPE.  
     The palladium 
catalyst complex can be precipitated from an organic phase of the 
carbonylation reaction which typically includes the ibuprofen product. 
The precipitated catalyst complex can be recycled without further 
treatment.

Patent EP-0437194-A3 (EP)
IPC: H01L29/423
Filed: 1991-01-02
Abstract: A semiconductor device includes an FET having side gate 
electrodes (50a to 50e), and the side gate electrodes, side gate 
input terminals and lead wires connecting them are arranged such 
that a difference between electrical lengths form the side gate 
electrodes (50a to 50e) to the input terminals (pads) (52) is 
smaller than a quarter wavelength of input signals thereto. 
Thus, even if a microwave signal is applied to the side gate 
input terminals, the signals reach the side gate electrodes (50a 
to 50e) with substantially same phase and the side gate effect 
extends to the entire gate electrode (20).
Patent EP-0489248-A3 (EP)
Title: Address control for a first-in first-out memory
IPC: G06F5/06
Filed: 1991-10-18
Abstract: The invention relates to a method and a device for selectively reading out of or writing into predeterminable storage areas of a first-in/first-out memory. In these memories, the read/write process is sequential, that is to say reading-out occurs in the same order as writing-in. In these memory arrangements, reading-out or writing-in in any order is not possible. In many applications, however, it is advantageous to process or repeatedly process particular storage areas. The method according to the invention and the corresponding arrangement provide the possibility for selective processing of particular storage areas. In particular, a repeated processing of a storage area is made possible by simple means by marking the start address which forms the basis of the processing of this storage area.   <IMAGE>

Title: Magnetically-coupled, two-resonant-circuit, frequency-division tag
IPC: G01V3/00
Filed: 1991-07-22
Abstract: A batteryless, portable, frequency divider includes a first resonant LC circuit (70) that is resonant at a first frequency for receiving electromagnetic radiation at the first frequency; and a second resonant LC circuit (74) that is resonant at a second frequency that is one-half the first frequency for transmitting electromagnetic radiation at the second frequency. The first circuit is coupled only magnetically to the second circuit to transfer energy to the second circuit in response to receipt by the first circuit of electromagnetic radiation at the first frequency. At least one of the resonant circuits includes a variable reactance element, such as a variable capacitance diode (D1<.>, D1<..>) or a varactor. In a variable reactance element (D1<.>) of the first circuit (70), the reactance varies with variations in energy received by the first circuit for causing the second circuit to vary in reactance due to mutual reactive coupling to cause the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency. In a variable reactance element (D2<.>) of the second circuit (74), the reactance varies with variations in energy transferred from the first circuit for causing the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency. Both resonant circuits include inductance coils (L1<.>, L2<.>) that are disposed on a ferrite rod (72), for enhancing the magnetic coupling. The frequency divider is included in a tag utilized in a presence detection system. <IMAGE>

Inventor: ZHANG JING
IPC: H04J3/06
Filed: 1995-10-12
Abstract: A plurality of digital transmission network analyzers (36) are arranged to analyze
and compare the appearance of a data packet on the plurality of ports of a network
(12). Each analyzer (36) has its own internal clock (50) for time stamping of data
packets in addition to other internal timing purposes. In order to synchronize the
time stamping of the packet as it appears to each analyzer at each different port,
the clock outputs of the several analyzers are connected together; and a
controlling CPU (40) commands one of the analyzers to supply the master clock
to the others. That master analyzer then commands the other analyzers to disable
or disconnect their own clocks, thereby all of the analyzers involved in a given
test are under timing control of the clock of the master analyzer. Packet headers
and time stamps are transmitted between analyzers for comparison, analysis and
reporting to the controlling CPU. This analyzer intercommunication is effected
over a separate bus (42) that interconnects all of the analyzers and the controlling
CPU.

Abstract: A method for reducing interferent bias such
as hemoglobin bias in immunoassays using dried slide
test elements featuring peroxidase and leuco dye as the
labeling mechanism. The method features the steps of:
   a) calibrating an immunoassay of a target
analyte by ascertaining the time at which the rate of
change in density produced by a first set of the test
elements for the target analyte on at least one liquid
having a known amount of interferent of choice and a
known amount of target analyte, crosses over or
minimizes the difference compared to the rate of change
in density produced by a second set of test elements
substantially identical to the first set of test
elements, on a liquid having the known amount of target
analyte but a negligible amount of interferent of
choice, and   b) conducting an assay of a patient sample
of unknown amount of the target analyte by reading the
rate of change in density in a third set of the test
elements substantially identical to the first and
second sets, caused by the sample, at a time
corresponding to the cross-over time ascertained in
step a).

IPC: G06F9/38
Filed: 1996-10-11
Abstract: In a variable word length VLIW-instruction processor, a
VLIW-instruction word length register is provided. A
VLIW-instruction contains an indication as to
VLIW-instruction word length such as a VLIW-instruction
word length rewrite instruction. Based on this
instruction, the VLIW-instruction word length of the
VLIW-instruction word length register is rewritten. For
the case of normal instructions (object programs) without
any indication of the VLIW-instruction word length, a
VLIW-instruction word length that is stored in the
VLIW-instruction word length register is initialized to a
predetermined value by, for example, the loading of an
initial program performed at the time of power-on. This
initialized instruction word length is used as a fixed
value and an object program for a conventional processor is
executed. Accordingly, even when the number of
instructions that are simultaneously executed is set low,
"NOP (non-execution)" is lessened and the effective use of
instruction memory becomes possible. In addition, it
becomes also possible to run object programs for
conventional processors.
