Title: Utilization of an air transfer system for fire control and air transfer system adapted for the purpose
IPC: G08B17/10
Filed: 1990-10-23
Abstract: The invention relates to an air transfer system, especially for a fire alarm appliance, having an air inlet aperture (8) and an air outlet aperture (10); in order to enable the fire alarm appliance (2) to be arranged behind a wall (14) limiting the room (16) to be monitored, an air distributor (20), having two air ducts (22, 24) passing through the latter from one end to the other is provided. This air distributor (20) makes it possible to connect both the air inlet aperture (8) and the air outlet aperture (10) of the fire alarm appliance (2) to the room to be monitored, so that the function of the fire alarm appliance, in particular that of the fan (6) arranged therein, is not impaired by ambient conditions which differ from the ambient conditions prevailing in the room (16) to be monitored.

Title: Profile made from form-pressed vegetable particles
IPC: E04C2/16
Filed: 1990-11-17
Abstract: The invention relates to the shaping of profiles (1), which are pressed in moulds from a mass of wood particles and the like, mixed with a binding agent, in the manner of the process described in EP-A-0,086,899. To increase the bending and warping strength of such profiles (1) and to make the profiles usable for forming frames, e.g. door frames, the invention proposes to form on one broad side of the profile (1) a relatively wide strip-shaped step (2) and on the opposite broad side of the profile (1) a plurality of continuous groove-shaped recesses (3). The webs (4) situated between or next to the recesses (3) are each constructed narrower in their width than the step (2), it being preferred for the width of the step (2) to be approximately equal to the sum of the widths of the webs (4). <IMAGE>

Patent EP-0381385-A3 (EP)
Title: Detector for colliding signals in asynchronous communication
IPC: H04L12/403
Filed: 1990-01-26
Abstract: A communications system has an active master node 
(10) which transmits request messages in serial bit fashion 
on a data bus (39), and a plurality of responder nodes 
(40,41) each of which receives the request messages on the 
data bus (39) and may respond to a request message with a 
serial bit answer message. The possibility exists that a 
plurality of responder nodes (40,41) may provide concurrent 
answer messages forming a composite signal which the active 
master node (10) may not be able to recognize as containing 
answer messages. A low pass filter (25,28) is provided in 
the active master node (10) which provides as its output 
only those pulses in the composite signal whose length is 
within a predetermined interval, typically from 
approximately a tenth to one half of the interval for each 
bit in the answer messages. A counter (29) receives the 
low pass filter output and provides a collision signal 
(Q₂) to the associated master node (10) if more than a 
preselected number of pulses within the predetermined 
interval are present. By providing the collision signal 
only after detecting a plurality of these pulses in the low 
pass filter (25,28) output, it is possible to avoid false 
detection of concurrent answer messages whose presence is 
simulated by noise on the line.

Title: Tri-deflection electron beam system
IPC: H01L21/027
Filed: 1990-02-20
Abstract: A three-stage E-beam deflection system employs breaking 
the entire field to be scanned into clusters and sub-­
fields. The scanning provided by the first stage of 
deflection which scans within the entire field is recti­
linear and discontinuous with the scan stopping in the 
center of each of the clusters where an exposure is to be 
made, and scanning is the same within each cluster from 
sub-field to sub-field. The scanning within a cluster by 
the second stage stops in the center of each sub-field 
where exposure is to be made. The third stage uses high 
speed electrostatic deflection to provide scanning with a 
vector scanning mode within the sub-field being scanned.

Abstract: A gerotor motor of the valve-in-star type in which the star (27) is disposed adjacent a
stationary valve plate (15). The stationary valve plate (15) defines a plurality N+1 of
stationary ports (65) in communication with the inlet port (55). The gerotor star (27) defines
a plurality N of fluid ports (51) each including a radially inner portion (53). The inner
portions 53 and the stationary port (65) are in commutating fluid communication as the star
(27) orbits and rotates, in accordance with an important aspect of the invention. As a result,
the star member (27) is exposed to a smaller area of pressurized fluid at the stationary valve
plate (15), thus making it possible to achieve more consistent overbalance of the star, for
either direction of rotation. This results in substantially improved overall efficiency of the
motor.

Abstract: An optical projection reduction system used in
photolithography for the manufacture of semiconductor devices
having a first mirror pair (M1, M2; M1', M2'; M1'', M2''), a
second field mirror pair (M3, M4; M3', M4'; M3'', M4''), and a
third mirror pair (M5, M6; M5', M6'; M5'', M6'').
Electromagnetic radiation form a reticle or mask (10) is
reflected by a first mirror pair to a second field mirror pair
forming an intermediate image (24, 24', 24''). A third mirror
pair re-images the intermediate image to an image plane at a
wafer (22). All six mirrors are spherical or aspheric and
rotationally symmetrical about an optical axis (OA). An
annular ring field is obtained, a portion of which may be used
in a step and scan photolithography system. In another
embodiment, weak refracting elements (R1, R2, R3) are
introduced to further reduce residual aberrations allowing a
higher numerical aperture. In the catoptric embodiment of the
present invention, a numerical aperture of 0.25 is obtained
resulting in a working resolution of 0.03 microns with
electromagnetic radiation having a wavelength of 13
nanometers. The optical projection reduction systems are 
intended for use at extreme ultraviolet to the soft X-ray
wavelength range. The present invention, provides a
relatively high numerical aperture and uses substantially all
reflective elements, greatly facilitating the manufacture of
semiconductor devices having feature sizes below 0.25 microns.
