Title: Fixing device for a detachable stanchion for a goods transportation vehicle
IPC: B62D33/02
Filed: 1989-03-28
Abstract: In a fixing device for a detachable stanchion 1 for utility vehicles, the lower end of the stanchion 1 is constructed as a transversely extending, cylindrical bearing element 20 which can be received in a bearing half shell 22 which is open towards the top, fixed to the vehicle and extends parallel to the bearing element 20. A wedge carrier on which a wedge 2 is arranged is displaceably mounted in a hollow space of the stanchion 1, it being possible to plug said wedge in a detachable manner from above into a wedge pocket 21 which is fixed to the vehicle and arranged above the bearing half shell 22. The wedge carrier is pressed downwards against a stop 19, which is securely arranged on the stanchion 1, by means of a compression spring 15 which is supported on the stanchion 1. <IMAGE>

transistors. The memory cells (MC₀₀ to MC₀₃, MC₁₀ to 
MC₁₃, MC₂₀ to MC₂₃, MC₃₀ to MC₃₃) which are arrayed in 
each row of the memory array (MM), are coupled with a 
plurality of word lines (WL0 to WL3). The word lines 
are selected by a row decoder (10) made up of a plu­
rality of partial decoders (10₀ to 10₃). In this case, 
a constant voltage output circuit (20), which is pro­
vided at the outputs of the partial decoders 10₀ to 
10₃) of the row decoder (10), outputs a constant voltage 
lower than a power source voltage to a corresponding 
word line of those word lines (WL0 to WL3) when the 
corresponding word line is selected by the outputs of 
the partial decoders (10₀ to 10₃).

Patent EP-0370692-A3 (EP)
Title: Magnetic resonance imaging methods and apparatus
IPC: G01R33/565
Filed: 1989-11-16
Abstract: In the magnetic resonance imaging method and 
apparatus, in the absence of signals supplied to gradient 
field coils (14), radio frequency signals, and magnetic 
resonance signals received by coil (18), analog-to-digital 
converters (44,46) indicate background noise and direct 
current (DC) offset. An attenuator (26) attenuates signals 
from the receiving coil (18) in the absence of magnetic 
resonance signals. A phase sensitive detector (38) 
produces real and imaginary signal components both in the 
absence of magnetic resonance signals during calibration and 
subsequently during the processing of magnetic resonance 
signals. The analog-to-digital converters (44,46), low 
pass filters (40,42), and the phase sensitive detectors (38) 
inject a undesirable DC offset into the signals. In the 
absence of a magnetic resonance signal, the digitized output 
of the analog-to-digital converters (44,46) is substantially 
the DC offset plus noise. A statistical anlysis means (64) 
analyzes the sampled analog-to-digital data in the absence 
of a magnetic resonance signal. Based on the variation 
among the samples, the desired level of confidence and 
accuracy, the statistical analysis means (64) determines how 
many samples must be averaged to determine the DC noise with 
the desired confidence. An averaging circuit (66,66′) 
averages at least the selected number of samplings. DC 
correction circuits (50,52) subtract the determined DC 
offset values for the real and imaginary channels from the 
real and imaginary magnetic resonance signals in subsequent 
scans before the magnetic resonance data is reconstructed 
(54) into image representations.

Title: Fir digital filter for high-speed communications systems
IPC: H03H17/00
Filed: 1990-02-15
Abstract: A finite impulse response digital filter for a digital communications 
system has successive virtual taps, 
the successive virtual taps having tap 
weight coefficients c₁ to c₅, respectively, 
where c₁ = c₅, c₂ = c₄, and c₃ 
is the coefficient of a virtual center tap. 
The filter comprises an add-and-­
delay multiplier circuit having three physical taps with tap weight 
coefficients d₁, d₂ and d₃, where 
d₁ = c₁ + c₂ = c₄ + c₅, d₂ = c₂ + c₃ = c₄ 
+ c₃, and d₃ = c₁ = c₅. 
The circuit comprises tap weight multipliers (1, 2, 3), 
delay elements (4, 6, 8, 10) connected to the 
tap weight multipliers to define the 
physical taps, and adders (5, 7, 9, 11). 
The arrangement is such that a first digital 
output sequence comprising 
d₁ × a i-2  + d₂ × a i-1  + d₃ × a i  appears at 
the output of one of the adders and a second digital output sequence 
comprising d₃ × a i-2  + d₂ × a i-1  + d₁ × a i  
appears at the output of 
another adder, where a i  represents 
a digital sample at a given instant, 
and a i-1  and a i-2  represent 
digital samples which are delayed for 
intervals T and 2T, respectively, with 
respect to a i , where T is the 
reciprocal of the symbol rate of digital samples of the communications 
system. The first and second output sequences are alternately sampled 
at intervals T and coupled to an output terminal of the digital filter.

Title: Double-walled pipe element
IPC: F16L39/00
Filed: 1990-08-10
Abstract: 2. It is intended to develop an easily assembled system consisting of double-walled pipe elements which can be produced individually at the works and whose ends are precisely circular and which can thus be welded together to form a pipeline system, without using any special clamping device. This object is achieved by means of double-walled pipe elements which are characterised in that   a) a centring ring is fitted on each of the two ends between the inner pipe and the outer pipe; b) a connecting ring is welded to each of the two ends, which ring connects the inner and outer pipe rigidly to one another and c) if necessary spacer rings are fitted as spacers to the inner pipe.   Such double-walled pipe elements are suitable for the assembly of pipeline systems in which corrosive fluids are conveyed.

according to the sign and magnitude of the positional 
value.

Title: Method for improving the printability of web offset paper
IPC: D21G1/00

IPC: H01L29/78
Filed: 1993-02-11
Abstract: The breakdown voltage of a VDMOS transistor is 
markedly increased without depressing other electrical 
characteristics of the device by tying the potential of 
a field-isolation diffusion, formed under the edge 
portion of a strip of field oxide separating a matrix 
of source cells from a drain diffusion, to the source 
potential of the transistor. This may be achieved by 
extending a body region of a peripheral source cell 
every given number of peripheral cells facing the strip 
of field-isolation structure until it intersects said 
field-isolation diffusion.  
     By so connecting one peripheral source cell every 
given number of cells, the actual decrement of the overall 
channel width of the integrated transistor is 
negligible, thus leaving unaltered the electrical characteristics 
of the power transistor.
