Patent EP-0942246-A2 (EP)
Inventor: KROENER ANDREAS DIPL-ING
IPC: F25J3/04
Filed: 1998-07-15
Abstract: If the condensed head fraction from the pure argon column is returned at varying rates the operation of the column becomes unstable. In order to avoid this a storage facility is provided in the return line so that these variations can be compensated on commands from associated instruments. This storage facility is shown as (6, 7) and is the actual return line, now kept about 90% full of condensate under control of valve (8). This valve is actuated according to the volume present in the return line by controller (10) acting on a signal from instrument (9). The head fraction, together with the head fraction from the raw argon column (not shown), is condensed in heat exchanger (5). The column works at a pressure slightly above 1 bar so that gas can be vented to atmosphere. The permissible variation of pressure is to be less than 0.2 bar.

Abstract: A thermal ink jet printhead is improved by providing a heater
resistor which is mechanically isolated from overlying nitride and tantalum
layers by growing a thin buffer oxide layer on the surface of the resistor
heater layer. The introduction of the buffer oxide layer permits a thinner
nitride layer which, in turn, reduces electrical resistance changes which
would otherwise be introduced into the resistor arrays by mechanical stress
after the nitride layer is deposited.

Title: Magnetic force microscopy probe
Inventor: MOSER ANDREAS
IPC: G01R33/12
Filed: 1998-02-16
Abstract: A probe (10) for use in an alternating current magnetic force microscopy (MFM)
system is located on the free end of a cantilever (50) in the MFM system. The probe
(10) has a pair of magnetic poles (P1,P2) that form part of a magnetic yoke and a
patterned electrically conductive coil (11) wound through the yoke. The probe (10)
includes a probe tip (20) that has a magnetic surface layer that is magnetically
coupled to one of the poles and extends from it. When alternating current from the
MFM system is passed through the probe coil (11) the magnetisation direction of the
probe tip correspondingly alternates. The interaction of these alternating magnetic
fields from the probe tip (20) with the magnetic fields emanating from the sample
whose magnetic fields are to be measured causes the cantilever (50) to deflect
between two extreme positions. The probe (10) can be formed from a portion of a
disk drive air-bearing slider with a patterned thin film inductive write head on its
trailing end by growing the probe tip (20) from the slider's air-bearing surface (ABS)
so as to be in contact with the gap and one of the poles of the write head. The probe
(10) can also be part of an integrated single-piece structure that includes the
cantilever (50), probe body and probe tip (20) which are formed using conventional
thin film deposition and lithographic processes.

Abstract: Methods and apparatus are disclosed for generating water
vapour for use in a semiconductor manufacturing process.
The disclosed methods comprise supplying oxygen and
hydrogen gases to a reactor, said reactor including a
catalyst that is capable of producing hydrogen and oxygen
radicals from said gases, which radicals react very
quickly with one another to form water; and thereafter
delivering water in gaseous form from the reactor;
wherein each of said gases is supplied to the reactor at
a respective pre-set flow rate, thereby to provide water
vapour from the reactor at a predetermined rate. A first
method is characterized in that on start-up the supply
of one of said hydrogen and oxygen gases is commenced at
its respective pre-set flow rate, and thereafter the
supply of the other gas is commenced and its flow rate
is increased progressively in such manner that said flow
rate of said other gas reaches its respective pre-set
rate after any residual amount of said other gas has been
delivered to the reactor, such that the rate of water
vapour generation does not exceed said predetermined
rate. A second method is characterized in that on start-up
the supply of one of said gases is commenced at its 
respective pre-set flow rate, and thereafter the supply
of the other gas is commenced, said other gas being
diverted away from the reactor until any residual amount
of said other gas has been purged. A third method is
characterised in that on start-up, water vapour delivered
from the reactor is discarded until water is delivered
from the reactor at said predetermined rate.

Inventor: DI SALLE DAVID ALAN
IPC: F01D11/02
Filed: 1998-12-17
Abstract: A blocker and swirl inducer hole configuration for use in connection
with a high pressure turbine is described. In one embodiment, the blocker holes
(50) are oriented to a 45-degree tangential angle with respect to the direction of
rotation of the seal (16), which results in pre-swirling the air before being
injected into the swirl cavity (52). In addition, the number of blocker holes is
reduced by as much as 50% of the number of blocker holes used in the known
CFM56 turbine. Further, rather than injecting the air into the first swirl cavity
(22) as is known, the air is injected into a second swirl cavity(52). The
combined effect of orienting the holes to the 45-degree tangential angle with
respect to the direction of rotation of the seal, locating the holes to open into the
second swirl cavity, and reducing the flow area by about 50%, results in an
increase in blocker hole pressure ratio. Increasing the blocker hole pressure
ratio results in a higher hole exit velocity which maxhnizes the cavity inlet
swirl. The blocker holes therefore not only provide back-pressure, but also
function as swirl-inducers. By inducing swirl into the air injected into the
second swirl cavity, better turbine disk rim cooling effectiveness is provided.
This result facilitates maintaining reasonable metal temperatures at increasingly
severe cycle conditions without the normally expected engine performance
penalties.

Title: Double-stacked hourglass log periodic dipole antenna
Inventor: POWELL CHARLES M
IPC: H01Q21/00
Filed: 1998-12-28
Abstract: An improved log periodic dipole antenna, adapted for use in a cellular telephone
system, has a plurality of radiating elements with differing lengths. The sequence of lengths
selected results in a horizontal beam width of about 65 degrees and a front-to-back signal
strength ratio exceeding 45 dB. This combination of characteristics reduces interference
among adjacent cellular telephone transmitter sites, and reduces waste of transmission energy
from the back of the antenna. A preferred sequence of radiating element lengths is
long-short-long-short-long, which may be described as a "double stacked hourglass"
configuration.

Abstract: In complementarily printing by bi-directional
scannings of a head (1) or by a plurality of print
heads, first patterns (pattern (a)) and second
patterns (pattern (b)) including reference dots for
example, dots formed by a forward scan of the bi-directional
scannings or by one of the plurality of
print heads and dots each having the different
direction of shifting of relative printing positions
to the reference dots are printed in corresponding
to the plurality of shifting amounts. These first
and second patterns have the similar characteristics
of a change in density. The difference is only that
their characteristics in density change are inverted
according to the direction of shifting. The
intersection point of these two characteristics in
density change is obtained as a position for
adjustment where dot-formed positions match. This
makes it easy to perform printing registration in a
printing apparatus in the case of printing by a
forward and reverse scan of a printing head or in
the case of printing by means of a plurality of
printing heads. In this case, operations by a user
etc. are also unnecessary and are easily performed.
