Abstract: The present invention relates to a method, an apparatus and a composite web made from stretched or prestressed thermoformable plastics films, thermoformable webs or sheets by deep-drawing, which are deep-drawn into the deep-drawing mould by the assistance of a pressure difference and by using heating, maintaining a temperature difference of more than 30 K (with respect to the deep-drawing mould), producing a grained effect and/or surface decoration. An at least two-ply plastics film, web or sheet having a thickness of 150 mu m - 5,000  mu m is heated and deep-drawn according to the invention by an upper layer or upper film facing the deep-drawing mould, the flow temperature or flow temperature range, crystalline melting temperature or melting range of the said upper layer or upper film being 3 - 50 K lower than that of the lower layer or lower film and/or its melt flow index MFI 170 DEG C/209 N/10 min being 1/50 to 3/5 of the melt flow index MFI 170 DEG C/209 N/10 min of the upper layer or upper film. In this method, heating devices having the same or approximately the same heating capacity are arranged on both sides of the web.

Abstract: The known keyless printing press of the type that it includes a delivery nozzle disposed in opposition to an ink source roller and provided with a plurality of delivery ports as aligned in parallel along the axial direction of the ink source roller and thereby printing ink circulating through an ink circulation system is delivered and fed through the respective delivery ports of the delivery nozzle to the ink source roller, is improved to obviate the shortcoming that isolated water may repeat­edly circulate through the ink circulation system and accumulate, resulting in lowering of a printing depth. The improvements reside in that an ink outflow port for making printing ink having a high moisture content propor­tion within the delivery nozzle flow out of the delivery nozzle, is provided in the delivery nozzle at a position higher than any of the delivery ports.

Title: Method for processing marine seismic data
Inventor: SHEIMAN JONATHAN LEWIS
IPC: G01V1/36
Filed: 1989-10-31
Abstract: Methods are provided for processing seismic data acquired during marine seismic operations when the seismic streamer cables or sources deviate from their desired acquisition track. The method initially processes the data using conventional normal moveout techniques, then applies conventional dip moveout techniques, followed by regularization of the cross-line data, and then 3-D migrating the regularized data. Regularization involves determining the signals at preselected cross-line positions based upon the signals detected and recorded at the measured cross-line CMP positions.

Abstract: An automatic gain control (AGC) amplifier (10), which may be fabricated as a monolithic integrated circuit, provides linear gain response in dB over a wide dynamic range. The AGC amplifier (10) comprises multiple cascode amplifier stages (A,B,C,D) connected in cascade to provide high power handling capability and high gain. A control voltage (VAGC) is input to a linearization circuit (16) which provides an output to an operational amplifier (18) that functions as a voltage controlled voltage source (VCVS). The VCVS (18) produces a conditioned control voltage (VAGC′) which is fed back to the linearization circuit (16) and provided to each of the cascode amplifier states (A,B,C,D). The conditioned control voltage (VAGC′) provided to each amplifier stage (A,B,C,D) causes current to be removed from the cascode amplifier, thereby lowering its gain. The overall gain of the AGC amplifier (10) in dB varies linearly with the control voltage (VAGC) applied to the linearization circuit (16).

IPC: H01L21/027
Filed: 1990-07-17
Abstract: A pattern is formed by first coating on a substrate a photosensitive organic polymer layer, and then an overlying film comprising an aminoalkoxysilane. After exposure in a predetermined pattern to radiation, the coated substrate is heated at a temperature so as to form an interfacial silicon-containing coupling layer between the film and the crosslinked portions of the polymer layer. Then, the coated substrate is contacted with a solvent so that the uncrosslinked portions of the polymer layer and the overlying portions of the film are simultaneously removed from the substrate. The process provides a high resolution, high aspect ratio pattern which demonstrates excellent etch resistance, while avoiding costly and cumbersome image transfer steps.

Title: Control circuit for a pulsed load in a vehicle
Inventor: FISCHER WERNER DIPL-ING
IPC: H03K17/06
Filed: 1990-07-26
Abstract: A circuit for the pulsed control of a load in a vehicle exhibits an N-channel enhancement MOSFET (MF) which, in its conducting state, supplies the load (L) to be pulsed with the positive potential of a battery. The other terminal of the load is connected to earth. The MOSFET is pulsed by a switching device (SE). The switching device alternately applies one of two potentials to the gate (G) of the MOSFET. One potential is the battery potential. The other potential is one which is picked up at the junction (V) between a diode (D) and a capacitor (C). The diode and the capacitor are connected between the battery terminal and the source (S) of the MOSFET. The capacitor acts as pumping capacitor in a pumping circuit which is used for raising the gate potential to a higher potential than the battery potential when the MOSFET is conducting. The switching device has a dual function in such a drive circuit. This is because it acts at the same time as a switching device for pulsing the MOSFET and as switching device in a pumping circuit. <IMAGE>

Abstract: Methods for making proton-exchanged, multi-­function integrated optics chips, preferably chips based on the stable, rhombohedral lithium niobate structure include the steps of: forming a multi-function integrated optics chip substrate from a substrate such as lithium niobate; affixing a removable mask or mask pattern to at least one surface of the chip to form one or more proton-exchanged patterns of desired size and shape at the surface of the chip; treating the masked chip with a proton-exchanging acid such as benzoic acid at a temperature and for a time sufficient to cause substantial proton exchange at and below the unmasked surface of the chip, but for a time insufficient to create any microcracking or internal stresses that lead to microcracking in the chip; removing the mask or mask pattern from the chip; and thermally annealing the chip, in an oxygen-containing environment, at a temperature and for a time sufficient to diffuse the hydrogen ions at and near the surface of the chip substantially below its surface, and for a time and at a temperature sufficient to restore and to optimize the electro-optic coefficient and to reduce light and propagation losses in the chip. 
     The chips so formed by this process have substantially diffused protons, are substantially free of   microcracking and of internal stresses that can result in microcracking, and yet have optimally high electro-optic coefficients.
