Patent EP-0442301-A3 (EP)
Title: Dynamic ram with on-chip ecc and optimized bit and word redundancy
IPC: G11C29/00
Filed: 1991-01-24
Abstract: A DRAM having on-chip ECC (30) and both bit and word redundancy that have been optimized to support the on-chip ECC. The bit line redundancy features a switching network that provides an any-for-any substitution for the bit lines in the associated memory array. The word line redundancy is provided in a separate array section (20), and has been optimized to maximize signal while reducing soft errors. The array stores data in the form of error correction words (ECWs) on each word line. A first set of data lines (formed in a zig-zag pattern to minimize unequal capacitive loading on the underlying bit lines) are coupled to read out an ECW as well as the redundant bit lines. A second set of data lines receive the ECW as corrected by bit line redundancy, and a third set of data lines receive the ECW as corrected by the word line redundancy. The third set of data lines are coupled to the ECC block, which corrects errors encountered in the ECW. The ECC circuitry (30) is optimized to reduce the access delays introduced by carrying out on-chip error correction. The ECC block (30) provides both the corrected data bits and the check bits to an SRAM (40). Thus, the check bits can be externally accessed, improving testability of the memory chip. At the same time, having a set of interrelated bits in the SRAM (40) improves access performance when using multi-bit access modes, which compensates for whatever access delays are introduced by the ECC. To maximize the efficiency of switching from mode to mode, the modes are set as a function of received address signals. <IMAGE>

Filed: 1992-12-30
Abstract: With a mould for the continuous casting of steel strip or thin slabs with cooled broad-side walls (1, 2) and narrow-side walls (3, 4), the broad-side walls form a funnel-shaped pour-in region (5, 8) which is reduced towards the narrow-side walls (3, 4) and in the casting direction to the format of the cast strip (6). The curvature of the pour-in region (5, 8) is defined by lateral circular arcs Rs and central circular arcs Rm connected to the latter at tangential points T. 
<??>To reduce friction and wear and to reduce the tensile and bending load on the strand shell, the radii (RsI - II) of the lateral circular arcs from the mould top edge are constant in a section (10) of the pour-in region (5, 8) extending from a point at least 100 mm down from the mould top edge.

Title: A method of facilitating interchanging the use of a mobile station and a permanently wired telephone set
IPC: H04M1/724
Filed: 1992-08-20
Abstract: The invention concerns a method of facilitating 
interchanging the use of a mobile station and a permanently 
wired telephone set, said mobile station being equipped with a 
keyset (4) and circuits connected thereto for controlling and 
performing desired functions, said keyset in addition to 
dialling and the like also permitting ordering such interchanging

number ordering is made possible of interchanging the mobile 
station and a telephone with this telephone number without 
dialling by means of the keyset. The number of the permanently 
wired telephone set is given as a bar code in its proximity. 
Interchanging is initiated by directing the bar code reader 
towards this bar code and pressing a function key predetermined 
for the purpose.

Title: Fluid treatment apparatus and method
Inventor: BARD STEVEN LINDZ
IPC: F26B21/00
Filed: 1993-06-21
Abstract: A new apparatus for treating substrates with fluids, as well as a corresponding fluid treatment method, is disclosed. The new apparatus includes a new configuration of fluid jet injectors which substantially overcomes the problem of dragout, in which fluid impinged upon an area of a substrate is retained on that area, preventing fresh fluid from reaching the impinged area. This new configuration also avoids imposing torques on substrates, and substantially reduces the need for rollers and guides for transporting substrates. <IMAGE>

Title: Punching tool
IPC: B26F1/36
Filed: 1993-08-09
Abstract: The punching tool has a stamping head with a die (12) and a one-sided punch (6). The one-sided punch (6) enables the tool to be inserted from below at any location of a curtain rail (1, 2, 3). According to the invention, a movable guide member (7) is arranged in place of the non-existing second punch half. During the second break-off step, the guide member (7) can snap into the first part already stamped out. This ensures that the second part to be stamped out comes to lie exactly opposite the first part, and in addition the guide member (7) provides for uniform and straight stamping-out. Furthermore, to position the punch (6) during the first break-off step, additional positioning aids (9, 10) can be provided at the guide member (7) or on the die (12).

Title: Propulsion unit
Inventor: ADAMS WERNER
IPC: B60T1/087
Filed: 1995-12-11
Abstract: The vehicle is driven by an engine and a transmission. The drive unit comprises a hydrodynamic retarder which has its rotor driven directly from the transmission. This drive is disconnected if no braking control is required. For a simple layout the retarder uses the same fluid as the engine coolant circuit, with excess energy removed by the main heat exchange. The retarder pump section is driven by a pinion coupling to the transmission using a suitable synchronising coupling. The retarder is positioned either in parallel to the transmission line or in line with same. The stator side of the retarder is supplied with fluid by a pump.

Inventor: BOWKER JEFFREY CHARLES
IPC: F23R3/30
Filed: 1995-06-07
Abstract: A low NOx generating combustor in which a
first lean mixture of fuel and air is pre-heated by
transferring heat from hot gas (41) discharging from the
combustor. The pre-heated first fuel/air mixture is then
catalyzed in a catalytic reactor (86) and then combusted so as
to produce a hot gas having a temperature in excess of the
ignition temperature of the fuel. Second and third lean
mixtures of fuel (32) and air are then sequentially introduced
into the hot gas, thereby raising their temperatures above
the ignition temperature and causing homogeneous combustion
of the second and third fuel air mixtures. This
homogeneous combustion is enhanced by the presence of the
free radicals created during the catalyzation of the first
fuel/air mixture. In addition, the catalytic reactor acts
as a pilot that imparts stability to the combustion of the
lean second and third fuel/air mixtures.

Abstract: A method of precleaning a silicon wafer to remove a layer 
of native silicon oxide thereon comprising adding a mixture 
of argon and oxygen to a plasma etch chamber (100) 
including a wafer (117) to be cleaned mounted on a cathode 
(119) in said chamber (100), while maintaining the pressure 
in the chamber (100) below about 0.4 Pa (3 millitorr). The 
oxygen is added to react with silicon atoms in the plasma 
but not with silicon atoms of the single crystal silicon 
wafer. The presence of oxygen in the plasma at low pressure 
ensures steady plasma generation and uniform etching across 
the wafer (117).

IPC: G06V30/10
Filed: 1996-04-12
Abstract: A forms creation and processing system which identifies and locates the active areas
(104,105,106,109) of a form (101) using forms landmarks (102,103,107,108). The present invention
eliminates the need to place predefined registration marks onto a machine readable form (101). The
active areas of a form are those which may contain a user created mark, such as a checkbox
(104,105,106) or a signature box (109). A form is preanalyzed at the same time that the active
areas are being described. The aim of the preanalysis is to find a set of graphic shapes, i.e.
landmarks, that can be found on the form independent of their location or orientation in the image.
Examples of such landmarks include paragraphs of text (107,108), heavy black lines and gray scale
areas. The analysis looks at the geometric distribution and regularities of the connected
components to choose a set of landmarks. The landmarks and active areas on the form are stored
in a forms control file. A forms interpreter uses the forms control file to locate and examine the
active areas of an instance of a form to determine if a mark has been placed thereon.
