Title: A device comprising a pair of cmos fets and a method of making it
IPC: H01L27/092
Filed: 1985-11-05
Abstract: All the gates and source/drain contacts in a CMOS device 
(1) are formed from polysilicon or polycide. Using two levels 
of polysilicon or polycide, the first level is used to simul­
taneously form the gate (10) of one (2) of the CMOS 
transistors and buried contacts (30, 31) to the source/drain 
regions (13, 14) of the other (3) CMOS transistor. The second 
level of polysilicon or polycide is then used to simultaneous­
ly form the gate (15) of the other (3) CMOS transistor and the 
buried contacts (28, 29) to the source/drain regions (8,9) of 
the first mentioned CMOS transistor. Because all the gates 
and contacts are polysilicon or polycide, it is possible to 
make interconnections between the gate on one of the 
devices and the source or drain of the other of the devices 
and between the gate on the other of the devices and the 
source/drain on said one of the devices simply by patterning 
the polysilicon or polycide layers.

Patent EP-0228037-A3 (EP)
IPC: C08G64/02
Filed: 1986-12-18
Abstract: This invention relates to an improved process 
for the preparation of poly(alkylene carbonate) polymer 
by the reaction of alkylene oxide with carbon dioxide 
and/or an alkylene carbonate at an elevated temperature 
and pressure. The improvement comprises conducting 
said reaction in the presence of a catalyst mixture 
comprising an alkaline catalyst and a stannate com­
pound. It is preferred to employ either ethylene oxide 
or propylene oxide because they are generally most 
reactive and give rise to the fewest by-products. Of 
these two, ethylene oxide is most preferred. It is 
also preferred to employ either sodium stannate or 
potassium stannate as the stannate compound and 
potassium carbonate, sodium metaborate, potassium 
 
 
hydroxide or potassium metaborate as the alkaline 
catalyst.

Patent EP-0197769-A3 (EP)
IPC: C25C1/16
Filed: 1986-04-03
Abstract: An electrolyte containing 65 g/l zinc and 150 g/l Cu is 
purified in zinc, that is, the copper is removed, by causing the 
electrolyte to fluidise a bed (8) of  1 / 2 mm copper particles. 
The bed is fluidised by 25% to make it 42 cm deep. An anode 
(11) is disposed above the top of the bed. A cathode (9) is 
disposed part-way up the bed. Copper is electroplated onto 
the bed particles. Any zinc which may be electroplated onto 
the bed particles tends to redissolve with concomitant 
cementation, on the particles, of copper, which can be 
recovered. The electrolyte is thus eventually completely 
stripped of copper and can be used for zinc electrowinning.  
     By controlling the pH of the electrolyte, substantially one 
metal, or one desired combination of metals, may be 
removed. In particular, pure copper deposition can be 
completed at low pH even in the presence of cadmium; upon 
a substantial increase in pH, cadmium deposition will occur.

container (4,5) independently of the other container (4,5), 
and in the preferred embodiment shown makes the assembly com­
prising the machine housing (l) and the container (4,5) easy 
to handle and manoeuvre. A wheeled carriage (6) provides the 
requisite mobility.

Title: Logical resource partitioning of a data processing system
IPC: G06F9/46
Filed: 1988-07-05
Abstract: The embodiment discloses a method and means for 
partitioning the resources in a data processing system 
into a plurality of logical partitions. Host control 
code may be embodied in programming, microcode, or by 
special hardware to enable highly efficient operation 
of a plurality of preferred guest programming systems 
in the different partitions of the system. The main 
storage, expanded storage, the channel, and subchannel 
resources of a system are assigned to the different 
logical partitions in the system to enable a plurality 
of preferred guest programming systems to run 
simultaneously in the different partitions. This 
invention automatically relocates the absolute 
addresses of the I/O channel and subchannel resources 
in the system to their assigned partitions. Also the 
absolute and virtual addresses of the different guest 
programming systems are relocated into, as well as page 
addresses for any expanded storage, their assigned 
partitions. The guest programming systems generally 
will be different operating systems. The logical CPU(s) 
of the guests are dispatched on one or plural real CPUs 
in the system using the S/370XA SIE (start interpretive 
execution) instruction. Special operations are 
provided, including the CPU alerting of other guests in 
different partitions using I/O interruption signalling. 
Interception is provided to handle special circumstances.
