Patent EP-0335459-A2 (EP)
Inventor: VAN LAARHOVEN JOSEPHUS MARTINU
IPC: H01L21/3205
Filed: 1989-03-24
Abstract: A method is described for providing insulating material on an electrically conductive level (1) of a substructure (10) forming part of an electronic device, which electrically conductive level has at least two spaced-apart electrically conductive regions (1a,1b). Insulating material (2,3) is provided over the electrically conductive level (1) to a thickness insufficient for insulating material on adjacent conductive regions (1a,1b) to meet thereby leaving a recess in the insulating material between the conductive regions (1a,1b). Next a planarising medium (5) is applied onto the insulating material (2,3) and etched so as to expose a top surface (3a) of the insulating material (2,3) thereby leaving planarising medium (5a) in the recess. The insulating material (2,3) is then etched anisotropically using the remaining planarising medium (5a,5b) as a mask so that the surface (11) of the electricallyconductive level (1) is exposed. The etching of the insulating material (2,3) is controlled so that the insulating material is etched away just down to the bottom (50a) of the planarising medium (5a) in the recess and the remaining planarising medium (5a,5b) is then removed so as to leave the surface of the substructure (10) between the electrically conductive regions (1a,1b) covered by a relatively flat layer (30) of insulating material. A further layer (6), for example of insulating material, is then deposited onto the remaining relatively flat layer of insulating material.

IPC: C07C31/04

Abstract: A single pressure process for the production of methanol wherein the make-gas is produced by steam reforming a hydrocarbon feedstock, in admixture with recycled purge gas from the synthesis loop, at such a pressure that the make-gas can be fed, without further compression, to the synthesis loop at a pressure no lower than the pressure at the inlet to said circulator. The reforming is effected by primary steam reforming followed by partial oxidation with oxygen and secondary reforming, without any bypass of the feedstock of the primary reforming stage, so as to give a make-gas of approximately stoichiometric composition for methanol synthesis. The primary reforming is effected at above 55 bar abs. over a catalyst disposed in tubes heated by passing the secondary reformed gas stream past the external surfaces of the reformer tubes in a direction counter-current to the flow of reactants undergoing primary reforming in said reformer tubes. In this way heat is transferred from said secondary reformed gas stream through the walls of said tubes to supply the endothermic heat of the steam reforming reaction. 
     In preferred forms of the process the steam is incorporated into the feed to the reformer by saturation and the excess of steam is removed from the reformed gas by direct contact with cold water: in this way a high pressure steam system recovering power from the reformed gas is not needed.

Abstract: A power inverter efficiency is optimized at high frequency in a fully resonant inverter operating with a range of load impedance that takes into consideration switching loss and conducting loss as a combined overall effect. Within this range of load impedance the inverter is constrained to operate with switching loss which is generally considered unacceptable in a conventional high frequency high efficiency power inverter, but the overall combined high efficiency of the disclosed power inverter has a wider range of load impedances than has been previously achieved in such a resonant power inverter. Non-linear capacitance across switching the device is positively utilized in achieving this goal.

Abstract: A connector (1) for a pacemaker electrode lead (2) has a plug pin (3), which is hollow in the longitudinal direction, for connection to a pacemaker and an insulating sheath (6) having, in the extension of the plug pin (3), a socket aperture (4) for receiving the free end (5) of the electrode lead (2), the electrically conducting connection being produced by clamping. In this arrangement, the longitudinal interior cavity (7) of the plug pin (3) fits over the insulated end (5) of the electrode lead and can be radially deformed for clamping thereto. At its end (3b) remote from the socket end (3a), the plug pin (3) carries the insulating sheath (6) with an insertion element (8) for the insulated region (5a) of the end (5) of the electrode lead, which lines the interior cavity (4) of the insulating sheath (6) to the extent that the remaining insulation (9) of the region (5a) can be easily pushed into the insulating sheath (6). The inlet element (8) projects beyond the end of the insulating sheath (6) and can be easily withdrawn after assembly. Clamping screws having a space requirement in the radial direction are advantageously avoided, so that the radial expansion of the connector (1) is correspondingly slight.

Abstract: A light source (610) comprising a source of radiation such as a single-electrode distributed feedback semiconductor laser diode is frequency modulated by direct current modulation with no pre-equalization or pre-distortion of the signal, and the optical signal is coupled to and carried by an optical fiber (622) to a remote location. At the remote location, an optical discriminator (626) such as a fiber Fabry-Perot interferometer can be used for both channel selection where more than one channel is being carried by the optical fiber and for covering the frequency modulation signal of each channel to an amplitude modulated signal. The amplitude modulated signal can be detected by a direct detection receiver (628). In those instances where signal enhancement is required, such as in long-haul lightwave transmission systems, an optical amplifier (624) can be substituted for the normally mandatory regenerator located at the repeater stations.

Abstract: Cationic polymerization of trioxane and a mixture of α,α- and α,β-isomers of glycerol formal (or their ester derivatives) yields acetal terpolymers having pendant functional groups (i.e., hydroxyl or ester groups pendent from the polymer's backbone). The glycerol formal monomers employed in this invention may include functional groups selected from hydroxyl or ester moieties which are protected from, and thus survive, the polymerization process with trioxane. These groups may then be present as functional reactive sites for the subsequent synthesis of block polymers and/or to chemically bind modifiers to the acetal terpolymer backbone, for example.
