Filed: 1987-01-23
Abstract: The invention relates to films, layers, tapes, plates and 
similar structures of metal or plastic materials coated 
with thin polyfluorocarbon films and being characterized 
in that no other materials are interposed. The polyfluoro­
carbon films are adherent and not porous and have controlled 
wettability characteristics.  
     The polyfluorocarbons have the formula (CF₂) n , wherein x 
has a value of from 0.3 to 2.0 and are directly obtained 
on the substrate by plasma polymerisation of gaseous streams 
of C₂F₆ and H₂, C₂F₆ and C₂F₄, CF₄ and H₂, CF₄ and C₂F₄ 
or C₂F₄.  
     The metal substrate can, for example, be Al, Cu, Fe, tin-­
coated Fe, Si, noble metals and alloys. The plastic sub­
strates can, for example, be polytetrafluoroethylene, poly­
propylene, polyethylene, polyphenylene oxide, polycarbonate 
and neoprene.

IPC: G06F3/06
Filed: 1987-09-07
Abstract: A FIFO memory device facilitates transfer of data 
between a host CPU and a peripheral device in one of a 
number of modes. In one mode, the FIFO memory device 
functions as two FIFO memories, one for passing data from 
the host CPU to the peripheral device, and one for passing 
data to the host CPU from the peripheral device. In another 
mode, the FIFO memory device functions as a single FIFO 
which facilitates passing data from the host CPU to the 
peripheral device or from to peripheral device to the host 
CPU.  
     The FIFO includes two RAMs addressed by a set of address 
counters. Of importance, the host CPU can bypass the 
address counters to directly address each RAM, thereby 
reading data from or writing data into either RAM regardless 
of the state of the address counters.

Patent EP-0243094-A3 (EP)
IPC: B28B1/38
Filed: 1987-04-15
Abstract: A method of making a ceramic mold includes covering both a 
pattern member (86, 88) and a body of expansion material with a layer (96) of 
ceramic mold material. The body of expansion material has a 
coefficient of thermal expansion which is greater than the 
coefficient of thermal expansion of the ceramic mold material. 
The layer of ceramic mold material and the body of expansion 
material are heated. This results in a cracking of the layer of 
ceramic mold material by the body of expansion material due to 
greater thermal expansion of the body of expansion material as it 
is heated. During the step of heating the ceramic mold material 
and body of expansion material (92), the pattern member is melted to 
separate the pattern from the layer of ceramic mold material.

Title: Bearing slabs for sectional false floors, ceilings, roofs or the like, and method for their production
IPC: C04B28/16
Filed: 1988-11-30
Abstract: Hitherto, sectional false floors have been produced from a trough- shaped body made of a material with high tensile strength and high modulus of elasticity and from a trough filling made of a material with low tensile strength and low modulus of elasticity, e.g. anhydrite. In the event of high point loading, the trough filling may be destroyed owing to its low tensile strength, whereas the trough is still able to carry load. The tensile, bending and edge strengths of the bearing slabs are to be increased and a method for their production which can be carried out in a small number of working steps without the previously required trough is to be provided. The bearing slab additionally contains a fibre material made of glass and/or steel, the fibre length being between 10 and 60 mm and the volume percent of the fibre material being 0.1 - 10 % by volume. The fibre material is added to the starting materials and this mixture is applied to the underside of a strong top covering. Used in the laying of service conduits. <IMAGE>
Patent EP-0280536-A3 (EP)
IPC: H01L29/08
Filed: 1988-02-24
Abstract: There is disclosed a specific turn-on/off driving 
technique for an insulated gate thyristor which has a 
first gate electrode (24) insulatively provided above a 
first base layer (14) and functioning as a gate (G1) of 
MOSFET (Q), and a second gate electrode (G2) formed on 
the second base layer. To drive the turn-on of the 
thyristor, a first voltage for conducting MOSFET (Q) is 
applied to the first gate electrode (G1), while substan­
tially simultaneously a second voltage for forwardly 
biasing between the second base layer (14) and a second 
emitter layer (18) is applied to the second gate elec­
trode (G2). To turn-off drive the thyristor (10), a 
third voltage for reversely biasing between the second 
emitter layer (18) and the second base layer (16) to 
stop the operation of the thyristor is applied to the 
second gate (G2), while the MOSFET (Q) is kept conduc­
tive. The thyristor starts turning off in response to 
the voltage application. At this time, charge carriers 
exhausted from the second emitter layer (18) are allowed 
to flow into the first base layer (14) through the chan­
nel region (CH) of the MOSFET (Q), thereby suppressing 
the local concentration of the turn-off current in the 
thyristor (10).
Patent EP-0283167-A3 (EP)
IPC: H04B14/04
Filed: 1988-03-02
Abstract: Apparatus and an associated method are described for encod­
ing an analog signal to a digital representation thereof and then 
decoding the same to reconstruct the original analog signal with 
reduced quantization noise and error. The analog signal is first 
adaptively pre-emphasized. A series of samples of the pre-em­
phasized signal are then obtained and encoded to create a series 
of digital representations which have a lower order resolution 
than the samples. The difference between each sample and its 
corresponding lower resolution digital representation is obtained 
and combined with the next sample. Decoding of the combined 
signals takes place in a complementary manner to create an ap­
proximate analog output signal, which is then de-emphasized in a 
manner complementary to the pre-emphasis to produce an analog 
output signal closely approximating the original analog signal. 
In a fully digital implementation the samples are converted to a 
digital format with a higher order resolution; the digital repre­
sentations are obtained from the digitized samples, and the 
difference measurements are combined with the samples in their 
digital format. In a hybrid digital/analog implementation the 
difference is combined with the analog signal prior to sampling.

Title: Process and apparatus for the production of generator gas and activated carbon from solid fuels
IPC: C01B32/336
Filed: 1988-09-14
Abstract: A process and apparatus for the production of generator gas and activated carbon from solid fuels is proposed, in which, in a first gasification stage, the fuel is fed by forced bottom-charging and preheated air in cocurrent of fuel and air and in which, in the second gasification stage, an intermediate gasification takes place with addition of secondary air and subsequently, in a third gasification stage, the gas is reacted with incandescent coke or charcoal, the heat of the issuing gas being used for heating the air. 
<??>The fuel entering the first gasification stage in the centre is here passed from the inside outwards and then upwards. A part of the entering fuel is precombusted in a prechamber connected with the preheated air feed, in order to reduce the oxygen content of the preheated air. In the intermediate gasification, the gas with the admixed air is passed through a Venturi nozzle with a diffusor, the fly coal entrained from the first gasification stage being at least partially recycled into the throat of the Venturi nozzle, and the recycle being assisted both by vacuum in the Venturi nozzle and mechanically.

an insulating layer. A second layer-wiring (7) insulatingly 
overlying the first layer is connected with the first 
layer-wiring via a third layer-wiring (13) which is resistant to 
a solution containing HF. When contact holes (8-12) are opened 
through the insulating layer so as to lead out the first 
layer-wiring (6) and/or a part of the semiconductor substrate, 
the first layer-wiring (6) is not exposed to HF containing 
solution for cleaning the exposed materials in the opened 
holes. Accordingly, a material having small electrical 
conductivity but soluble by the HF can be employed for the 
layer-wiring allowing a high density integration as well 
good electrical contact with the Si substrate and with 
other multi-layer wirings.
