Patent EP-0341082-A3 (EP)
IPC: F16D25/08
Filed: 1989-05-05
Abstract: A release mechanism for a clutch (10) having an 
axially movable release sleeve (13) is disclosed. A 
pressure ring (22) is mounted about the release sleeve 
(13) by a bearing (20). When the pressure ring (22) is 
moved toward a disengaged position, it moves the 
release sleeve (13) in the same direction. A piston 
housing (25) is mounted about an inner flange (11a) 
formed on a cover (11) of the clutch by a bearing (26). 
The piston housing (25) is disposed adjacent to the 
pressure ring (22) and includes an annular groove (28) 
formed therein which extends away from the pressure 
ring (22). An annular piston (29) is disposed within 
the groove (28), defining a chamber within the piston 
housing (25). An external port (31) provides 
communication between the chamber and a source of 
pressurized fluid for selectively moving the piston 
(29) axially outwardly into engagement with the 
pressure ring (22). When so actuated, the pressure ring 
(22) is moved axially outwardly, causing the release 
sleeve (13) to be moved to the disengaged position. A 
hollow pressure ring cover (40) is attached about the 
pressure ring (22) having circumferential flat portions 
(40a) formed thereon. One of the flat portions (40a) 
abuts the adjacent axially extending leg of an L-shaped 
bracket (43), which is secured to the housing (42) of a 
transmission or other non-rotating member, so as to 
prevent rotation of the pressure ring (22) and the 
piston housing (25).

Title: Visual navigation and obstacle avoidance structured light system
IPC: G01S17/931
Filed: 1989-09-06
Abstract: A vision system for a vehicle, such as a mobile robot (10) includes at least 
one radiation projector (14,16) which projects a structured beam of radiation 
into the robot's environment.The structured beam of radiation (14a, 16a) prefer­
ably has a substantially planar pattern of sufficient width to encompass the 
immediate forward path of the robot and also to encompass laterally disposed 
areas in order to permit turning adjustments. The vision system further includes 
an imaging (12) sensor such as a CCD imaging device having a two-dimensional 
field of view which encompasses the immediate forward path of the robot. An 
image sensor processor (18) includes an image memory (18A) coupled to a device 
(18D) which is operable for accessing the image memory. Image processing 
is accomplished in part by triangulating the stored image of the structured 
beam pattern to derive range and bearing, relative to the robot, of an object 
being illuminated. A navigation control system (20) of the robot inputs data 
from at least the vision system and infers therefrom data relating to the confi­
guration of the environment which lies in front of the robot. The navigation 
control system generates control signals which drive propulsion and steering 
motors in order to navigate the robot through the perceived environment.

onic compound containing positively charged nitrogen and neg­
atively charged oxygen. The polymerization reaction is slow, 
and therefore particularly useful in such operations as resin 
transfer molding.

Patent EP-0401521-A3 (EP)
Title: Semiconductor memory device
IPC: G11C7/22
Filed: 1990-05-07
Abstract: When data read out from a memory cell array (11) is 
output to an external device through an output buffer 
(15), a first read control pulse signal (P1) and a 
second read control pulse signal (P2a) are generated in 
response to a change in address signal (Add). An operation 
for reading out data is controlled using the first 
and second read control pulse signals (P1, P2a). By 
such control, when an address signal (Add) seems to be 
changed by noise generated by a change in power source 
potential or the like due to a change in output, the 
noise can be removed, and thus the output (15) buffer is 
not erroneously operated.

Title: Method for the determination of strength of join between ceramic and non-ceramic material
IPC: G01N29/11
Filed: 1990-04-17
Abstract: The strength of a join between a ceramic and an 
associated non-ceramic is determined using an 
ultrasonic microscope. A converging ultrasonic beam 
(B) is radiated against a point (P) on a surface of the 
ceramic (1), said point being a predetermined distance 
away from the join (3) between the ceramic (1) and the 
associated non-ceramic (2). Data on the intensities of 
interference waves at respective predetermined varia­
tions of the relative distance between a probe (5) of 
the ultrasonic microscope and the ceramic (1) are col­
lected. The residual stress at the point is calculated 
on the basis of the cycle of echo intensities of the 
interference waves for the respective predetermined 
variations of the relative distance. The strength of 
the join is then determined on the basis the residual 
stress.
