Title: Active suspension system for an automotive vehicle with slip angle dependent control for enhanced steering characteristics
IPC: B60G17/016
Filed: 1989-10-17
Abstract: An active suspension control system performs 
anti-rolling control in response to vehicular rolling by 
inducing counter rolling in a direction opposite to the 
vehicular body rolling direction. Magnitude of counter rolling 
is differentiated between front and rear suspension systems for 
providing desired steering characteristics. The steering 
characteristics is adjusted depending on the demand on 
stability factor in cornering. The stability factor criterion may be 
based on the vehicular lateral slip angle 
or slip angular velocity while the 
rolling magnitude monitoring means comprises a lateral acceleration 
sensor.

Title: Method of and device for sub-micron processing a surface
IPC: G11B9/14
Filed: 1989-09-15
Abstract: A method of and a device for sub-micron deforming a

Patent EP-0347173-A3 (EP)
Title: Expulsion fuse
IPC: H01H85/38
Filed: 1989-06-13
Abstract: A supersonic expulsion fuse for interrupting fault 
currents in high voltage alternating current networks, has an 
arc interruption region with a long length of supersonic 
turbulent flow and little or no subsonic plasma. This 
increases the arc interrupting capability against both thermal 
and dielectric arc reignitions. Therefore, the transient 
recovery voltage the network applies across the interrupted arc 
after current-zero may be increased in both frequency and peak 
values, relative to known expulsion fuses. The fuse may be 
used on power distribution systems as a power fuse in 
enclosures or overhead where the system transient recovery 
voltages exceed the capabilities of conventional distribution 
cutouts.

Patent EP-0348305-A3 (EP)
Title: Coded modulation communication system
IPC: H04L27/34
Filed: 1989-06-23
Abstract: In Trellis coded modulation system in which an input 
digital signal in parallel form is encoded by a 
convolutional encoder which adds an additional bit to the 
input digital signal for error correction purpose, and a 
mapping circuit designates amplitude and phase for each 
symbol for QAM signal, the number of parallel bits at 
output of said convolutional encoder is the same as the 
number of parallel bits of an input digital signal. An 
input digital signal is first rate converted so that m+n 
bits in every T period is converted to m bits in every T′ 
period, where T′=(m/(m+n))·T. The convolutional encoder 
adds n number of bits so that the total number of parallel 
bits is m+n, which is applied to the mapping circuit. In a 
receive side, a receive signal having m+n bits in every T′ 
period is decoded through an error correction decoder 
which provides m bits in every T′ period, then, the 
decoded signal is rate converted to m+n bits in every T 
period. So, the number of parallel bits does not increase 
in spite of convolutional encoding, but a transmission 
rate is a little increased. The coding gain in the present 
invention is improved since the number of levels of the 
QAM signal is not increased although the bandwidth of the 
signal is a little increased because of the higher clock 
rate.

Title: Rewinding machine for the formation of rolls of paper or the like
IPC: B65H19/22
Filed: 1990-03-08
Abstract: A rewinder for converting large supply rolls of 
paper into smaller rolls (B) such as toilet tissue and 
kitchen towels includes a pair of winding cylinders 
(11, 13) the surfaces of which are spaced slightly 
apart to create a nip (1) therebetween. The cylinders (11,13) 
rotate in the same direction, so as to create opposing 
surface movement in the area of the nip (1). A web of 
paper (N) enters the nip (1) and crosses therethrough from one 
winding cylinder to the other, passing firstly the 
winding cylinder (11) the surface of which is moving 
in a direction opposite to the incoming direction of 
the web (N). A core (A) on which the web (N) is to be wound is 
to be inserted into the nip (1), pinching web (N) between the 
first winding roll (11), causing a reverse movement in 
the direction of the web (N) and separating the web (N) in the 
nip (1) between the two winding cylinders (11, 13). The 
core (A) has adhesive on its surface which contacts the 
web (N) and causes the leading edge of the web (N) to fold 
back upon itself and wind up on the core (A) under the 
action of the second winding cylinder (13) to create a 
small log or roll (B) of paper on the core (A) in the 
space between the two winding cylinders (11,13). The invention 
includes means (19) for taking up the slack in that 
portion of the advancing web (N) immediately in front of 
the winding cylinder (11) during the period when the 
leading edge of the web (N) folds back upon itself and 
before it begins to wind up on the core (A) under the 
action of the second winding cylinder (13).
