Patent EP-0355921-A3 (EP)
IPC: F02G1/055
Filed: 1989-08-17
Abstract: An improved conduit assembly for coupling a heat 
pipe evaporator with a a Stirling engine heat exchanger. 
The conduit assembly features a cylindrical main tube section 
connected to a flared shell joining the heat exchanger of 
the Stirling engine. The flared shell provides an increasing 
cross-sectional area which reduces the velocity of vaporized 
heat pipe working fluid flowing from the heat pipe evaporator 
to the heat exchanger. Such reduced velocity has been found 
to minimize entrainment of liquid within the transmitted 
vapor. The conduit assembly further includes an internal 
small diameter liquid return duct which provides additional 
isolation of the liquid and vapor phases of the heat pipe 
working fluid as a means of further reducing entrainment. 
Surface tension breakers are provided which communicates 
the heat exchanger to the inlet end of the liquid return 
duct to wick away liquid working fluid from the heat 
exchanger. Contaminant gases within the heat pipe are 
removed through the use of an externally heated getter and 
an internal getter within the vapor flow path.

Title: A precursor of a low thermal stress polyimide and a photopolymerizable composition containing a polyimide precursor
IPC: G03F7/038
Filed: 1989-08-23
Abstract: Disclosed is a polyimide precursor comprising a specific 
polyamic acid ester, polyamic amide or polyamic acid salt 
structure derived from a tetracarboxylic acid compound and a 
diamine compound, which can be converted by heating to a 
polyimide having low thermal stress. By blending a specific 
form of this novel polyimide precursor which has an ethylenic 
double bond, with a photopolymerization initiator, an 
excellent photopolymerizable composition can be obtained. Not 
only this precursor but also the crosslinked precursor 
obtained by the photopolymerization of the photopolymerizable 
composition can be converted by heating to a polyimide resin 
which has low thermal expansion coefficient, high heat 
resistance, excellent mechanical properties and satisfactory 
adhesion to a substrate. Hence, the precursor and the 
photopolymerizable composition can advantageously be utilized 
in the production of electrical and electronic components.

Patent EP-0391517-A3 (EP)
Title: Method and apparatus for ordering and queueing multiple memory access requests
IPC: G06F12/08
Filed: 1990-01-29
Abstract: In a pipelined computer system, memory access functions are simultaneously generated from a plurality of different locations. These multiple requests are passed through a multiplexer 50 according to a prioritization scheme based upon the operational proximity of the request to the instruction currently being executed. In this manner, the complex task of converting virtual-to-physical addresses is accomplished for all memory access requests by a single translation buffer 30. The physical addresses resulting from the translation buffer 30 are passed to a cache 28 of the main memory 14 through a second multiplexer 40 according to a second prioritization scheme based upon the operational proximity of the request to the instruction currently being executed. The first and second prioritization schemes differ in that the memory is capable of handling other requests while a higher priority "miss" is pending. Thus, the prioritization scheme temporarily suspends the higher priority request while the desired data is being retrieved from main memory 14, but continues to operate on a lower priority request so that the overall operation will be enhanced if the lower priority request hits in the cache 28.

Title: Intron sequence analysis method for detection of adjacent and remote locus alleles as haplotypes
IPC: C12Q1/68
Filed: 1990-08-20
Abstract: The present invention provides a method for detection of at least one allele of a genetic locus and can be used to provide direct determination of the haplotype. The method comprises amplifying genomic DNA with a primer pair that spans an intron sequence and defines a DNA sequence in genetic linkage with an allele to be detected. The primer-defined DNA sequence contains a sufficient number of intron sequence nucleotides to characterize the allele. Genomic DNA is amplified to produce an amplified DNA sequence characteristic of the allele. The amplified DNA sequence is analyzed to detect the presence of a genetic variation in the amplified DNA sequence such as a change in the length of the sequence, gain or loss of a restriction site or substitution of a nucleotide. The variation is characteristic of the allele to be detected and can be used to detect remove alleles. Kits comprising one or more of the reagents used in the method are also described.

Title: Electrode structure of monolithically-formed heavy-current element and small signal element and method of manufacturing the same
IPC: H01L23/532
Filed: 1991-08-16
Abstract: The semiconductors according to the present invention 
have a structure in which a heavy-current element 
and a small signal element are formed on a semiconductor 
substrate (11). The electrode of the small signal 
element is formed from an aluminum film (19), whereas 
that of the heavy-current element is formed from aluminum 
film (19), titanium film (24), and aluminum film 
(25). Thus, the thickness of the heavy-current element 
is thicker than that of the small signal element by the 
total thickness of the titanium film (24) and the aluminum 
film (25). With this structure, the current capacity 
of the device can be increased by thickening the 
electrode of the heavy-current element, and the degree 
of integration of the device can be enhanced by thinning 
the electrode of the small signal element, without 
employing a multi-layer wiring technique.

of the process gas pressure entering the 
chamber,     
and 
   P' ver     is the rate of change with respect to time 
of the verification gas pressure entering 
the chamber.     
The volume and temperature are maintained constant during 
the verification procedure.

Title: Electrolytic cell and processes for producing alkali hydroxide and hydrogen peroxide.
Inventor: SHIMAMUNE TAKAYUKI
IPC: C25B1/46
Filed: 1994-02-04
Abstract: The electrolytic cell 1 for producing alkali hydroxide or hydrogen peroxide is divided into the anode compartment 3 and the cathode compartment 4 by the cation exchange membrane 2. The cathode compartment 4 is further divided by the anion exchange membrane 6 into the solution compartment 7 containing a concentrated aqueous solution of alkali hydroxide and the gas compartment accommodating the gas cathode 8. The anion exchange membrane 6 prevents the gas cathode 8 from coming into direct or indirect contact with the aqueous solution of alkali hydroxide. This leads to the extended life of the gas cathode. The above-mentioned arrangement is effective in large-sized electrolytic cells. Thus, the present invention can be applied to industrial electrolysis which has never been achieved with the conventional gas electrode. <IMAGE>   <IMAGE>
