Title: Laser radar system
Inventor: HARRIS MICHAEL
IPC: G01S17/08
Filed: 1991-11-14
Abstract: A laser radar system comprises a laser (11) having a laser cavity (12) between first and second output ports (13, 14). The laser output beam (Lt) is directed through the first port along an optical path (15) onto a target (5). Scattered light (Lr) is collected back along the transmitted optical path into the laser cavity (12). The scattered light (Lr) is amplified in the laser cavity (12) and passes out through the second port (14) of the laser cavity onto a detector (17). A portion of laser light (Lt), forming a local oscillator signal, also emerges through this second port (14) onto the detector (17) on which the beat between the two beams produces a signal used by a signal processor (18) to provide a desired measurement such as a range, velocity, or vibrational frequency value. The laser (11) may be an Ar ion, or CO2 laser, and may be a cw or pulsed operation laser. The first and second ports may be partly, eg 90%, reflecting mirrors. <IMAGE>

Title: A thread delivery device for textile machines
Inventor: SCHUBERT FRANK
IPC: D04B27/14
Filed: 1992-03-20
Abstract: A thread delivery device for a textile machine such as a loom or warp knitting machine which processes groups of threads (1) e.g. from a warp beam 51 with a regulatable drive (5) has a low-mass thread rocker (3) upstream of the processing station and in addition differences between the delivered and required thread length cause surplus thread to be stored in an intermediate thread store (4). The store (4) has a thread guide element such as a tubular roll (45) rotatable in bearings on the free ends of supporting arms (42) which in turn are mounted on a torsionally rigid tube (41) which is loaded in the pivoting direction e.g. by a spring (441) acting through a loading arm (43). The arm (43) further cooperates with sensors (54) to control the drive of the warp beam (51) in accordance with the position of the guide element (45). Instead of the spring (441) the loading may be applied by a pneumatic, hydraulic or electromagnetic device. <IMAGE>

Title: Semiconductor memory device and fabricating method therefor
Inventor: CHO HYUN-JIN
IPC: H01L27/108
Filed: 1992-06-30
Abstract: A semiconductor memory device comprising one transistor consisting of a source (14), a drain (16) and a gate electrode (18), a bit line (30) in contact with the drain region of the transistor via a first contact hole (5), a storage electrode (100) in contact with the source region of the transistor via a second contact hole (7), a first planarized insulating layer (22) formed under the bit line and a second planarized insulating layer (24) formed under the storage electrode (100) in which the material layer formed under the conductive layers, e.g., the bit line and storage electrode, is planarized to prevent stringers created due to surface indentations. Further, due to a spacer (40, 42) being formed directly on the side walls of the contact hole, or on the side walls of a pattern for forming the contact hole, contact is effectively prevented between conductive layers, thereby improving the memory device's reliability and assisting in the realization of high density. <IMAGE>

Title: A gas flow control regulator
Inventor: TATAREK-GINTOWT ANDREW RICHARD
IPC: G05D7/01
Filed: 1992-08-05
Abstract: In a combined gas flow control regulator and pressure relief valve, the pressure relief valve includes a pressure relief member comprising a flange (20) and a sleeve (18) which is sealingly engaged with the piston rod (4) of the gas flow control regulator and is slidable relative to the piston rod (4). A spring (24) urges the flange (20) of the pressure relief member into contact with the piston head (3) of the gas flow control regulator thereby closing a gas relief aperture (22) in the piston head (3) capable of connecting a first chamber (8), which is one chamber of the gas flow control regulator, to a second chamber (9) which is a gas relief chamber from which gas can escape to atmosphere. The pressure relief member moves as one with the piston of the gas flow control regulator in normal operation of the gas flow control regulator, and the pressure relief member moves away from the piston head (3) against the action of the spring (24), independently of the motion of the piston, when excess pressure builds up within the regulator body, to allow this excess pressure to be vented to atmosphere through the second chamber (9). <IMAGE>

Title: Low power change-of-contact-state detector
Inventor: HOLLANDS DANIEL H
IPC: G06F1/32
Filed: 1992-12-01
Abstract: A change of state detector 10' is provided that minimizes the amount of power required to monitor the state of one or more switches or contacts 20, 22. The number of components utilized is minimized to simplify the manufacturing process and reduce the expense of the detector. The detector supplies pulses to the or each contact to determine its state and compares the present state with the previous state as indicated by a signal from a dormant processor unit 16'. If the comparison shows a change of state, a wake-up signal is applied to the processor unit. The detector may be part of a gas meter, in which the processor unit counts actuations of contact 20 according to gas flow and reports the count over a communication link 18', anti-tamper contact 22 also being monitored. The comparison is effected using XOR logic (Figs 2, 5). <IMAGE>
