Abstract: A 2-substituted amino-4 (1H)-pyrimidone derivative 
shown by the general formula 
  
wherein R¹ and R², which may be the same or different, each 
represents a hydrogen atom or a lower alkyl group; R³ 
represents an alkyl group, an alkenyl group, an alkynyl 
group, a halogen-substituted alkyl group, a halogen-­
substituted alkenyl group, a halogen-substituted alkynyl 
group, or an alkyl group interrupted by an oxygen atom or a 
sulfur atom; R⁴ represents a hydrogen atom or a lower alkyl 
group; m is an integer of 1 or 3 and n is an integer of 2 or 4 
(with said R⁴ being a lower alkyl group when R¹ and R² are 
hydrogen atoms, R³ is an alkyl group, m is 2 and n is 3) or an 
acid addition salt thereof.  
     The compounds of this invention have both histamine 
H²-receptor antagonist activity and gastric cytoprotective 
activity and are very useful as drugs for gastric diseases.
Patent EP-0183400-A3 (EP)
IPC: A61M5/172
Filed: 1985-11-01
Abstract: A control system for an angiographic injector precisely 
regulates the speed of a motor (M) used to expel contrast 
medium from a syringe, for instance. The control system is 
centered around a microprocessor (1) which receives com­
mands from the operator via a key-board and then regulates 
the speed of the motor (M) by supplying drive command 
pulses to a circuit which integrates the difference in frequen­
cy between the command pulses and another pulse train 
whose frequency is proportional to actual motor speed. The 
control system also includes a velocity loop which uses the 
back EMF of the motor (M) to supply an analog voltage also 
proportional to motor speed to a difference amplifier (20) in a 
conventional velocity loop. The system is a dual loop 
controller where the second loop (F) provides approximate 
speed control, while the first loop (E) provides a "velocity 
correction" voltage required to bring the system to zero 
steady-state speed error. Motor speed pulses are provided 
by an incremental encoder (9,10), the pulses from which are 
counted by the microprocessor (1) to limit the volume of fluid 
injected. Various safety systems guard the injector's per­
formance and help prevent over-volume injections. These 
systems are part of the velocity control and are also 
disclosed.
Patent EP-0193152-A3 (EP)
IPC: D06F39/00
Filed: 1986-02-24
Abstract: The apparatus comprises a source of linearly polarized 
light to be propagated through the washing solution and to 
be diffuced by the micelles and the emulsion.  
     Photodiodes receive the diffused light through respec­
tive analyzers oriented with their polarization directions 
parallel to the polarization direction of the primary light, and 
perpendicularly thereto, respectively. The apparatus deter­
mines the condition of the washing solution at the microsco­
pic level by the use of variations of the polarization of the 
radiation diffused by the micelles and by the emulsion.

Title: Transplantable artificial tissue and process
IPC: A61K35/39
Filed: 1986-08-22
Abstract: A transplantable artificial tissue matrix structure contain­
ing viable cells which is suitable for insertion into the body is 
made by polymerizing precursors in an aqueous solution to 
form a shape retaining solid matrix comprising viable cells, 
matrix polymer and reversible gel polymer. The solution con­
tains a matrix polymer precursor, a reversible gel polymer 
precursor, and viable cells. The reversible gel polymer is dis­
solved and removed to yield an insoluble, porous matrix con­
taining viable cells. The conditions and reagents are selected 
to maintain the viability of the cells. The invention is part­
icularly suitable for artificial transplant matrix tissue contain­
ing pancreatic islet cells.
Patent EP-0228901-A3 (EP)
IPC: H01L21/67
Filed: 1986-12-23
Abstract: The invention provides wafer transferring 
apparatus for wafer processing apparatus, for 
example an ion implanter, plasma etcher, or sputter 
coater, in which wafers are automatically loaded into 
processing stations (23, 24, 25) in the process chamber 
(35) of the apparatus from storage cassettes (1, 2, 3) 
located in a vacuum lock (38). Wafers are lifted in 
batches by a pick-up means (5) from the cassette and 
transferred into a cradle (9) which holds more than one 
wafer. The cradle is then moved to load into a 
processing station each wafer of the batch previously 
loaded into it. Consequently the number of cycles of 
the transferring apparatus is fewer than the number of 
wafers to be loaded, and particulate contamination of 
the processing chamber (35) is reduced.

Abstract: The invention disclosed relates to the art field 
embracing positive displacement reciprocating compressors 
of the type featuring hydraulic drive, and 
sets out to simplify the construction of such units, 
rendering them more functional at the same time. 
Four coaxial bulkheads (1, 2, 3, 4) are adopted, set 
apart one from the next by three cylinder barrels 
(5, 6, 7) and three pistons (8, 9, 10) which are

diameter than the remainder. Hydraulic oil from a 
power pack driving the compressor flows alternately 
into chambers (14, 15) which are occupied by the rod 
(11), and bounded at one end by one of the pistons 
(8, 10) of smaller or greater diameter.

Title: Cross-lapper
IPC: D01G25/00
Filed: 1988-11-07
Abstract: The invention relates to a cross-lapper (1) with at least two rotating conveyor bands (6, 7) and at least two carriages (4, 5) moved in a reversing manner and accelerated at the reversal points of their travel. To influence the pile thickness in a controlled manner, the band running speed and the travelling speed of the carriages are uncoupled from one another between the acceleration phases and are set differently in relation to one another. For this, there are separate drives (14, 15), especially servo-drives, at least one of which has a freely programmable control (15, 13). In the travel zones between the reversal points of the carriages (4, 5), a constant or variable speed difference in relation to the conveyor bands (6, 7) is produced, this being expressed in a change in the deposited pile thickness (9). When the carriages (4, 5) move faster, the pile becomes thicker, and with the opposite speed difference the pile thickness becomes smaller.

Abstract: A stable, low resistance contact is formed in a 
contact hole (16) through an insulating layer (14), e.g., 
silicon dioxide, formed on a surface of a semiconductor 
substrate (12), e.g., silicon, to a portion of a doped 
region (10) in said semiconductor surface. The contact 
comprises (a) an adhesion and contacting layer (18) of 
titanium formed along the walls of the insulating layer

barrier layer (20) formed over the adhesion and contacting 
layer; and (c) a conductive material (22) formed over the 
barrier layer and at least substantially filling said 
contact hole. A patterned metal layer (26) forms an ohmic 
contact interconnect to other devices and external circui­
try.

are either physically or chemically vapor deposited onto 
the oxide surface. The conductive layer comprises one of 
CVD or bias sputtered tungsten, molybdenum or  in   situ  
doped CVD polysilicon.  
     The contact of the invention avoids the problems of 
encroachment at the oxide-silicon interface and worm holes 
associated with other contact schemes but retains process 
simplicity.
