Patent EP-0863293-A2 (EP)
Inventor: JENNE DIETMAR DIPL-WI-ING
IPC: E21B44/06
Filed: 1998-03-05
Abstract: Feed rate produced by feed drive when drilling in the ground is controlled by a hydraulic circuit (10-86) as a function of the torque occurring at the drilling tool. Preferably the feed rate is controlled on the basis of the difference between the actual torque and a set-point torque, so that the feed rate is less than a predetermined value. The feed rate may additionally be controlled as a function of the feed force, for which a limiting value is defined. A control system is used for carrying out the method. It involves a pressure medium flowing to the hydraulic rotary drive can be regulated by a control valve.

Patent EP-0875929-A2 (EP)
Inventor: ILG MATTHIAS
IPC: H01L21/3205
Filed: 1998-03-21
Abstract: A method of filling gaps between adjacent gate
electrodes of a semiconductor structure. A self-planarizing
material is deposited over the structure. A
first portion of such material flow between the gate
electrode to fill the gaps and a second portion of such
material becomes deposited over tops of the gate
electrodes and over the gaps to form a layer with a
substantially planar surface. A phosphorous dopant is
formed in the second portion of the self-planarizing
material. Thus, relatively small gaps may be filled
effectively with a layer having a very planar surface for
subsequent photolithography. The phosphorous dopant
provides gettering to remove adverse effects of alkali
contaminant ions which may enter the gap filling
material. The dielectric constant of the material filing
the gaps, i.e., the first portion of the gap filling
material, being substantially free of such contaminants,
has a relatively low dielectric constant thereby reducing
electrical coupling between adjacent electrodes. The
self-planarizing material is a flowable material. The
flowable oxide may be spun on or may be deposited by
gaseous deposition. The phosphorous dopant may be
provided by, for example: implanting phosphorous ions
into the second portion of the self-planarizing layer and
heating the material to both cure such material and
activate the phosphorous ions; depositing a phosphorous
doped layer over the layer of self-planarizing material,
heating the structure to out-diffuse the phosphorous
dopant into the second portion of the self-planarizing
material and selectively removing the deposited layer; or
by curing the spun-on self-planarizing material in a
phosphine environment.

Abstract: An adaptive filter which is realized as an FIR filter employing
stochastic gradient algorithm comprises a step size controller for
controlling step size α c   (n)  so as to minimize the mean squared
estimation error ε (n)  at each time n. The step size controller regards a
step size α c   (n)   opt  which satisfies  δε (n+1) /δα c   (n)   opt  = 0  at each time n as
a theoretical optimum step size, and sets the step size α c   (n)  at each time
n so as to be approximately equal to the theoretical optimum step size
α c   (n)   opt . For example, when the adaptive filter employs stochastic
gradient sign algorithm as the tap weight control algorithm, the step
size controller provided with a leakage accumulator (13) calculates a
vector q (n)  one by one according to the update equation:  q (n+1)  = (1-ρ)q (n) 
+ ρsgn(e n  + ν n ) (|e n  + ν n |) 1/2  a (n)    (ρ : leakage coefficient, e n : an error
signal sequence component, ν n : an additive noise sequence component,
a (n) : an input signal sequence vector), and sets the step size α c   (n)  at each
time n as:  α c   (n)  = β ∥ q (n)  ∥  2    ( β = 1.07870520/trace(Ra 2 ) ,  Ra =
E[a (n) a (n)T ] ). By the step size controller, both faster convergence of the
adaptive filter and smaller residual mean squared estimation error after
convergence can be attained.

Abstract: The present invention relates to radio communication antennas and in
particular relates to multi-user detection for CDMA antenna array receivers. A
reverse link (mobile to base) of a cellular direct sequence code division
multiple access system is provided which increases system capacity whilst
avoiding system complexity. The invention provides a method of signal
detection which is based on the partitioning of users into equivalence classes
by beam-forming with subsequent standard multi-user detection techniques
applied within each class. Computation techniques are simplified and
processing time can be considerably reduced. Furthermore, the capacity of a
conventional receiver may be improved by employing multi-user detection
techniques. These techniques are particularly useful for systems which
involve large numbers of users. A method of operation is also disclosed.

Abstract: A method for detecting a fault condition of
a conductive path (34) utilized for conducting
combustion signals produced by a combustion sensor
(26) of an internal combustion engine (10) to an
electronic controller (30) involves sensing a voltage
level on the conductive path (34) and comparing the
sensed voltage level to a predetermined threshold
value. If the sensed voltage level is less than the
threshold value, a fault condition of the conductive
path (34) is indicated. The method enables
identifying the existence of the conductive path fault
condition as well as distinguishing it from other
problem conditions such as a misfire.

Abstract: The power level for uplink data transmission in a wireless communications
network utilizing an on-demand multiple access method with a fair queuing service
discipline (ODMAFQ) for efficient utilization of the limited bandwidth available in
the wireless network is established during the initial access request message. The
power level in a wireless network having a base station and several remote hosts is
established by first transmitting a short connection request message to the base station
from one of the remote hosts at an initial power level that is set relative to the
nominal open loop power level. If the first remote host's transmission is
unsuccessful, the power level is incremented by a power increment amount that may
be predetermined, and the steps of transmitting and incrementing are repeated until
the transmission from remote host to base station is successful. Finally, the power
level at which transmission is successful is stored and used for further data
transmission between that particular remote host and the wireless network base
station.

Abstract: A normally closed, three-way valve (10) comprises a housing (12) having a
supply passage (14), a control passage (16), and an exhaust passage (18). A valve assembly
controls communication between the passages. The valve assembly includes a
valve (20) in the supply passage (14) to open and close communication between the
supply (14) and control passages (16). The valve assembly also includes a second valve (22)
in the exhaust passage (18) to open and close communication between the control (16) and
exhaust passages (18). The supply passage valve (20) is normally held closed by the
pressure of hydraulic fluid in the supply passage (14). A solenoid (24), when activated,
moves the exhaust passage valve (22) to closed position. A pintle (70) between the two
valves is shifted in one direction by the closing of the exhaust passage valve to
open the supply passage valve against the pressure of fluid in the supply
passage. The pintle is shifted in the opposite direction by the supply passage
valve when the solenoid is de-activated, to move the exhaust passage valve to
its open position. A spring (42) in the supply passage acts on the supply passage
valve in the open position thereof and during an initial portion only of its
movement toward the closed position to assist the fluid pressure in the supply
passage in moving that valve to the closed position. The spring is loosely
captured between the supply passage valve and a stop (40) in the supply passage so
that it does not act on the supply passage valve when it is closed. Hence, the
supply passage valve is held closed solely by the pressure of fluid in the supply
passage.
