Herstellung der genannten elektrischen Verbindungen ver­
zichtet werden.

Abstract: A method for surface treating of thin substrates such as 
semiconductor wafers, wherein a semiconductor wafer formed with 
deep and minute trenches on its surface is horizontally placed on 
a spinner in a chamber with its trenched surface directed up, and 
then ultraviolet light is emitted to the surface of the wafer to 
dissolve impurities sticking in the trenches, and thereafter 
etchant is spouted from a nozzle to the trenched surface of the 
wafer being spinned about a vertical axis at a high speed, and 
next the inside of the chamber is rendered at a lower pressure 
than atmospheric pressure and the atmospheric pressure is 
recovered after the lapse of a predetermined time, and thus a 
series of these steps of etchant supplying, pressure reducing, 
and pressure recovering are carried out until the complete 
entrance of the etchant into the interior surfaces of the 
trenches is effected, so as to even or smooth the interior 
surfaces, and finally the wafer is treated with rinsing, and 
heating and drying.

Patent EP-0255742-A3 (EP)
IPC: H01J29/48
Filed: 1987-07-21
Abstract: A television camera tube which has an anti-comet-tail 
electron gun. In such tube a target plate (11) is line scanned by a 
focused electron beam which is at a cathode voltage of typically zero 
volts to stabilise the scanned area of the target plate (11) at that 
voltage and in so doing producing an output signal. During line flyback, 
the cathode voltage is increased to 5 V and the beam current is 
increased so that the target plate (11) is stabilised at that voltage. 
By this means the effects of moving high intensity lights can be 
mitigated.  
     However if the electron beam is focused during flyback 
then intense damage can be done to the photo-conductive layer of the 
target plate. A television camera tube is described in which the 
electron gun (14) is a multi-spot triode electron gun comprising a 
cathode (15), a multi-apertured control grid (16) and a multi-apertured 
accelerating anode (17). During line scanning a single low current 
electron beam is produced from the centre of the cathode (15) and during 
line flyback a plurality of low current electron beams are produced to 
form a large spot which does not damage by ion bombardment the photo-­
conductive layer of the target plate (11).

Title: Non-manual speech-conferring device
IPC: H04R3/00
Filed: 1988-07-14
Abstract: In a known teleconferencing system, a noise-adapting threshold circuit is used to generate a voltage level which is representative of the background noise and is compared with the microphone signal of a relevant microphone in order to ascertain whether the microphone is receiving speech. The invention is designed to enable clear identification of speech signals. To achieve this, after micro-individual bandpass filtering in the fundamental voice frequency range, the speech envelope is detected from the composite microphone signal adjusted according to the ambient noise, the level of the bandpass-filtered microphone signals is monitored and the microphone signal with the highest level, depending on the speech envelope detection signal, is passed onto the transmission path. The method according to the invention is particularly suitable for use in hands-free conferencing devices in noise-filled rooms, where the remote station is connected to the hands-free conferencing device via a telephone circuit. <IMAGE>

composition having a property of liquid under 
the room temperature because of its 
crystallinity disordered owing to random 
structures, which composed of 1,6-hexanediol and 
polyvalent alcohol having side chain.  
     Accordingly, the disclosed composition has 
more excellent processability in the case of

prepared by reaction of an organic diisocyanate 
compound with the polycarbonatediol composition.  
     The disclosed polyurethane resin has more 
excellent properties under the low temperature 
atomosphere, while retaining high levels of 
mechanical strength, more excellent resistibility 
under the heat and moist atomosphere, etc. and 
thereby maintaining a good balance of properties.  
     The polyurethane resin, which is produced in 
the present invention, is more useful in a very 
wide variety of forms including spandex, rigid or 
flexible urethane foams, thermoplastic urethane 
elastomers and thermosetting urethane elastomers, 
adhesives, synthetic leather and paints, etc.

Abstract: A system for inflating e.g. a pair of lumbar 
support bags of a vehicle seat comprises two pumps (4) each 
connected to a respective bag and controlled by a common 
electronic control system (7). The control system causes 
each bag to be inflated over a period of between 1 and 10 
minutes, the inflation of one bag taking place whilst the 
other bag is deflated and vice versa to produce alternating 
pressure zones in the lumbar region. Inflation of each bag 
is produced by a multiplicity of individual spaced apart 
energizations of the associated pump. The duration and 
spacing of the energizations is variable to produce the 
desired complete inflation of a bag within the required 
period. In the preferred embodiment the duration of each 
energization is preset during manufacture of the system but 
the spacing of the energizations is under the control of 
the user of the seat to vary the duration of the 
inflate/deflate cycle.
