Patent EP-0259109-A3 (EP)
IPC: B01D63/00
Filed: 1987-08-28
Abstract: A permeable membrane system comprised of at least two 
sheets, at least one of the two sheets being a permeable membrane 
and at least one of the two sheets having regularly spaced 
grooves on at least one surface, the sheets being positioned in a 
configuration with the grooves on the surface of one sheet form­
ing feed channels with a surface of the covering sheet. In the 
preferred configurations, both sheets are permeable membranes. 
In one configuration of the system, the grooved sheets may be posi­
tioned so that the grooves in one sheet are aligned with the 
grooves in an adjacent sheet, whereby the grooves in one sheet 
form parts of the feed channels and the corresponding grooves of 
the other sheet form the other parts of the feed channels. Or, 
the grooved sheets may be alternated with planar sheets so that 
the grooves of the grooved sheets form the channels with the ad­
jacent surface of a planar sheet. The sheet may instead be ar­
ranged with grooves for feed channels covered by the planar sur­
face of a sheet with grooves on its other surface for a permeate 
channel which are parallel or perpendicular to the grooves of the 
sheet for the feed channels. In still another configuration, at 
least one of the sheets contains grooves for feed channels on one 
surface of the membrane and parallel or perpendicular grooves for 
a permeate channel on the other surface of the membrane. 
 
  
     Separation processes utilize the permeable membrane systems. For 
those separations, the permeable membrane system is preferably made in 
the plate-and-frame or spiral-wound configuration.

Title: Method and apparatus for autonomous vehicle guidance
IPC: G05D1/02
Filed: 1988-08-22
Abstract: A system that allows a vehicle (8) to autonomous­
ly move toward an arbitrary destination over an irregular 
surface where home base can be out of sight. During the 
outward bound journey, a robot (18) or the vehicle (8) 
places path markers (10) along the route. A tracking 
system tracks the most recently placed marker (10) and 
records outbound movement of the vehicle (8) relative to 
the marker (10). Each marker (10) includes flashing 
colored lights (42) that allow the marker (10) to produce 
a unique identification signal. When a marker (10) goes 
out of sight for a predetermined distance and cannot be 
found by side to said and up/down camera scans, the robot 
(18) places another marker on the ground. During a return 
trip in an inward bound direction toward home base, the 
tracking system tracks the most recently placed marker (10) 
and guides the vehicle (8) to the marker (10). When the 
most recently placed marker (10) is reached, the robot (18) 
can pick up the marker (10) or bypass the marker (10) and 
then the vehicle (8) tracks the next most recently placed 
marker (10).

IPC: G01H3/14
Filed: 1988-05-23
Abstract: The device for measuring, indicating and controlling 
ambient sound pressure levels comprises a probe (8) 
connected to a sound level meter (2), the output 
signal from which is proportional to sound pressure 
picked up by the probe; the signal from the meter is 
compared with a given threshold, and if found to be 
higher, causes a control signal to be generated that 
triggers the operation of indicator lights or alarms 
(6), and/or of a limiter (4) by which sound pressure 
in the environment is attenuated automatically.  
     The device is intended for use in surroundings such 
as discotheques, building sites or factory premises 
etc., where sound pressure levels attributable to 
noise generated within the environment can prove a 
source of annoyance, or even of harm, to persons 
occupying the area.

Title: Multilevel quadrature amplitude modulator capable of reducing a maximum amplitude of a multilevel quadrature amplitude modulated signal regardless of transmission data information or redundant information
IPC: H04L27/34
Filed: 1989-06-29
Abstract: In order to produce first and second Lee-error 
correcting code sequences in a multilevel quadrature 
amplitude modulator comprising a code converting unit 
(10) for converting first and second 2 m  -level input 
digital signals into first and second major converted 
signals by rearranging a square signal point arrangement 
into an approximately circular arrangement on a phase 
plane, each of the first and the second major converted 
signals consisting of m binary bits numbered from a 
first (least significant) bit through an m-th (most 
significant) bit, a first error correcting code 
producing circuit (21) carries out error correcting 
calculation for the first through an n-th bits of the 
first major converted signal to produce the first 
Lee-error correcting code sequence where n represents an 
integer (2 ≦ n ≦ m). Similarly, a second error correcting code 
producing circuit (22) produces the second Lee-error 
correcting code sequence. The first and the second 
major converted signals are multiplexed with the first 
and the second error correcting code sequences into a 
first and a second major multiplexed signal, respec­
tively, which are then modulated into a multilevel quadrature 
amplitude modulated signal. In a counterpart multilevel 
 
 
quadrature amplitude demodulator, an inverse operation 
is carried out to produce the first and the second input 
digital signals.

Title: Semiconductor light detector and method of manufacturing the same
IPC: H01L31/107
Filed: 1989-09-29
Abstract: A semiconductor light detector includes a first 
semiconductor layer of a first conductivity type having 
a multi-layer structure including a light absorbing 
layer and an avalanche multiplicating layer, an annular 
second semiconductor layer (27) formed on the first 
semiconductor layer, a light detecting region (29) 
formed by doping an impurity of a second conductivity 
type in a surface region of the first semiconductor 
layer, in such a manner that a peripheral portion of the 
light detecting region (29) is located outside an inner 
periphery of the second semiconductor layer (27), the 
light detecting region (29) defining a first p-n junc­
tion in combination with the first semiconductor layer, 
and a guard ring (28) formed by doping an impurity of 
the second conductivity type in a surface region of the 
first semiconductor layer to surround the peripheral 
portion of the light receiving region with the first 
semiconductor layer, the second p-n junction having a 
concentration gradient lower than that of the first p-n 
junction. By virtue of the presence of the second semi­
conductor layer (27), the junction depth of the periph­
eral portion of the light detecting region (29) is less 
than that of the central portion of the light detecting 
region (29), and the junction depth of the guard ring 
(28) is greater than that of the peripheral portion of 
the light detecting region (29). As a result, a suffi­
cient guard ring effect can be obtained without a guard 
ring (28) having a great junction depth.
