Title: Polarisation filter
Inventor: VAN DER TOL JOHANNES JACOBUS G
IPC: G02B5/30
Filed: 1992-07-07
Granted: 1997-09-09
Abstract: Polarisation filter for delivering an output signal So containing only one (TE or TM) of the two polarisations (TE and TM) in an input signal Si, comprising an intermediate guide section (5) between an input section (A) and an output section (B). The output section (B) is a mode splitter having a monomodal output channel (3) for the output signal (SO) and a monomodal dummy channel (4) which recedes beyond the interaction distance (D). The output channel (3) has a lower propagation constant than the dummy channel (4). The input section (A) having an input channel (1) and a dummy channel (2) is an inverse mode splitter which may be the mirror image of the output section (B). The guide section (5) is monomodal for one of the two polarisations and bimodal for the other polarisation. Both polarisations of the input signal Si entering via the input channel (1) are initially converted into first-order modes, of which only one is a guided mode of that conductor section and reaches the output section, where it propagates further along the channel having the lowest propagation constant. The first-order mode of the other polarisation escapes (6).

Patent CA-2121895-C (CA)
Inventor: SCHOEPF VICTOR LEE
IPC: G01V1/22
Filed: 1991-10-23
Granted: 2000-02-01
Abstract: A method and apparatus for acquiring acoustical data from a borehole and is especially useful in carrying out tomography surveys. The borehole digital geophone (BDG) tool of the present invention is capable of operating from a standard, 7-conductor logging cable with no special cables being required since the individual digital geophone modules (DGM) which form the BDG tool are connected together by short, separate lengths of the same 7-conductor cable.      Each DGM acquires, digitizes, stacks, and stores data generated by its own three-component geophone assembly prior to transmitting these signals to the surface over a dedicated conductor in the cable thereby substantially increasing the sample rate of the tool which, in turn, substantially reduces the field time to run a tomography survey.

Title: Anode structure for magnetron sputtering systems
Inventor: SIECK PETER A
IPC: H01L21/203
Filed: 1994-05-12
Granted: 1999-07-06
Abstract: An elongated anode structure having multiple points to which electrons are attracted is provided. The anode can be constructed of multiple wire brushes that are attached to a metal rod.  Use of the anode in magnetron  systems  significantly  reduces  dielectric material build-up and improves film uniformity in both dc reactive and non-reactive sputtering.  Moreover, the anode reduces overheating and increases the operation time of magnetron systems undergoing reactive sputtering of  dielectric  materials.    In  one  embodiment,  the magnetron system has a cylindrical cathode and a pair of elongated anodes positioned parallel to and equidistance from the cathode.  The anode structure is particularly suited  for  sputtering  uniform  films  of  dielectric materials,  including  silicon  dioxide  and  silicon nitride.

Abstract: A continuous belt press has a frame having horizontally  and vertically spaced upper and lower plates defining a horizontally extending gap having an upstream end and a downstream end and vertically spaced upper and lower upstream drums rotatable on the frame about respective horizontal drum rotation axes at the upstream end. Vertically spaced upper and lower downstream drums are rotatable on the frame about respective horizontal drum rotation axes at the downstream end and upper and lower endless steel belts are spanned over the respective upper and lower drums and each have a working stretch lying between the plates and a return stretch. Upper and lower sets of rollers are engaged between the working stretches and the respective plates. The drums are driven to advance the belts to move the working stretches horizontally in a transport direction to displace a workpiece in the direction through the gap. The downstream drums have a diameter which is greater than that allowable by the tension in the respective belts as they move around the downstream drums and the upstream drums have a diameter which issubstantially less than the diameters of the respective downstream drums and that would not be usable on the downstream drums because it would exceed the permissible belt tension. Drives are provided for rotating the downstream drum with a predetermined torque and for rotating the upstream drum with a torque equal to between 0% and 75% of the predetermined torque of the downstream drums.

The application of a unique insulator layer allows flexible interconnections with conductor crossovers to address pixel arrays in formats other than X-Y matrix addressing. The absence of edge connections and a bulky edge seal permits production of a tiled display in which module-to-module spacing is not limited by connectors or seals. Multiple electroluminescent display modules may be tiled together edge-to-edge to form a large display panel.
