Patent EP-0794640-A3 (EP)
Inventor: SPRUNK ERIC
IPC: G06F21/00
Filed: 1997-01-10
Abstract: The integrity of a group of secure processing
elements (10, 20, 30, 40, 50, 60, 70, 80) in a
communication system is ensured with a validation
scheme. Member elements (10, 20, 30, 40, 50, 60,
70, 80) are checked by adjacent members to determine
whether a member has been tampered with or
operatively removed from a group. If a member is
found to be untrustworthy, propagation of group
characteristic information to that member will be
halted. The group characteristic information
defines the group, and is required by each group
member in order to function. The untrustworthy
member is therefore effectively exiled from the
group. An efficient network topology minimizes
inter-member message traffic while maintaining group
robustness.

Abstract: A double-row ball bearing suitable for office 
automation equipment comprises an axle (1) supported for 
rotation within a sleeve (2) by means of first and second 
sets of ball bearings (5, 9). The first set of ball 
bearings (5) runs between an axle ball race (3) formed

ball race (4) which may be formed directly in an inner 
surface of the sleeve (2) or in an outer ring mounted in 
the sleeve (2). The second set of ball bearings (9) runs 
between an inner ring (6) mounted on the axle (1) and an 
outer ball race (8) formed in an inner surface of the 
sleeve (2). The inner ring (6) is pre-loaded and then 
fixed to the axle (1) to provide a suitable axial clearance 
between the sets of ball bearings.

Abstract: A distance measuring device includes first and
second cameras, first and second Fourier pattern data
generating sections, a pattern processing section, and a
distance measuring section. The two cameras are spaced
apart from each other by a predetermined distance. The
first Fourier pattern data generating section generates
first two-dimensional Fourier pattern data by performing
two-dimensional discrete Fourier transform for image
data picked up by the first camera as first pattern
data. The second Fourier pattern data generating
section generates second Fourier two-dimensional pattern
data by performing two-dimensional discrete Fourier
transform for image data picked up by the second camera
as second pattern data. The pattern processing section
synthesizes the first and second Fourier two-dimensional
pattern data, and performs either two-dimensional
discrete Fourier transform or two-dimensional discrete
inverse Fourier transform for the synthesized data. The
distance measuring section obtains a correlation peak in
a range excluding a portion near a reference position in
a correlation component area appearing in the
synthesized Fourier two-dimensional pattern data, and
measures the distance to a target on the basis of the
distance from a reference position in the correlation
component area to the position of the correlation peak.

Abstract: A CHE programmed memory device (30) avoids forward
biasing at an isolated P-well (38) junction with a deep N-well
(36) and prevents emitting electrons that may cause voltage
buildup across the isolated P-well region (38) by applying a
forward bias current (50) or voltage source (40) connected to
the deep N-well region (36) for slightly forward biasing the
deep N-well region. This maintains the voltage drop of
isolated P-well region (38) below the diode turn-on voltage.

Abstract: Processes for cleaning a silicon body and for
controllably decreasing the thickness of a silicon dioxide
layer (25) overlying a silicon substrate (15) are disclosed.
The processes comprise chemically etching a silicon dioxide
layer (25) with a dilute etchant in the presence of a megasonic
field. The concentration of the etchant is preferably less
than its diffusion-rate-limiting threshold concentration at a
given temperature. When aqueous alkaline hydroxyl ion etchants
are employed, the concentration of etchant is preferably less
than about 300 ppm by weight relative to water. The etching
is discontinued before the silicon substrate is exposed to the
etchant. The etch rate is controlled to within about 2 x 10 -5 
µm/min (0.2 Å/min) of a target etch rate which ranges from
about 3 x 10 -5  µm/min (0.3 Å/min) to about 4 x 10 -4  µm/min (4.0
Å/min). A simpler, more cost-effective chemical process for
robustly cleaning silicon bodies or for producing very thin
gate oxides is achieved.

Abstract: For realizing a satisfactory and stable developing process,
the charge state of a developer and the density of toner particles
contained in the developer is kept constant in the developing
process. A developing roller (4) to be driven rotationally is
provided in a developing tank (3) containing a developer. The
developer is sucked magnetically using the magnetic force of a
magnet (4b) provided in a developing sleeve (4a) composing the
developing roller (4). The developer is then fed into a developing
area opposed to a photosensitive member (1), then collected into
the developing tank (3) after the developing process is ended.
The magnet (4b) is composed of an odd number of magnetic poles;
developing pole (N1), feeding pole (S1), magnetic force
distribution adjusting pole (N2), developer sucking pole (S2),
developer separating pole (S3), auxiliary collecting pole (N3),
and collecting pole (S4). Between the sucking pole (S2) and the
developing pole (N1), an even number of poles are disposed.
Between the developing pole (N1) and the separating pole (S3) are
disposed an even number of poles. Consequently, the developer
used for visualizing an image is separated while it is stuck on
the developing sleeve when the developer is separated at the
separating pole (S3). When the developer is replaced, sticking
of toner on the developing sleeve can be reduced significantly.
In addition, the supplied developer is fixed in both toner density
and charging level at the developing pole (N1) in developing.

occupied for a propagation loss fluctuation that is

prediction unit. For the prediction of the propagation

smaller the cell radius is, the faster the propagation
loss fluctuates.

Abstract: A receiver for a station in a wireless local area network using a common wireless
communication channel and employing a CSMA/CA (carrier sense multiple access with
collision avoidance) protocol includes various modes. In normal mode, the receiver follows
typical states in order to detect a message and demodulate data from the message properly.
Meanwhile, a process implements a message-in-message (MIM) mode when an energy
increase above a specified level is detected. While in the MIM mode, if a carrier is
detected, the energy increase is caused by a new message; otherwise, the energy increase is
caused by an interfering station. If the carrier is detected, the receiver begins retraining so
that it can start receiving the new message as soon as the first message ends. If no carrier is
detected, the receiver waits a specified time to detect a carrier or for the end of the first
message, after which the receiver returns to the beginning of the normal mode. While in
the normal mode, if a message is detected that is not addressed to the station, the receiver
enters a hunt mode. While in the hunt mode, the receiver waits for the current message to
finish. At the same time, a process implements retraining when both an energy increase
above a specified level and a carrier are detected. If no carrier is detected within a specified
time, or if the energy level decreases below the specified level, the receiver returns to the
beginning of the normal mode.
