Patent DE-4124420-A1 (DE)
Inventor: WALBROEHL HEINZ-THEO
IPC: E21D9/06
Filed: 1991-07-23
Abstract: The invention concerns a tunnelling shield with individual cutters or an enclosing casing, in which the rear ends (4) of the cutters or the tail of the casing act as the outer shell for installation of the concrete sections. The rear ends (4) of the cutters or the tail of the casing leave voids (30) which have to be filled to avoid subsidence. In order to fill these voids (30) immediately a concrete section is produced, the invention calls for the end section (6) of each cutter rear end (4) to be in the form of at least one tongue (8) or for the end section of the casing tail to be in the form of a multiplicity of tongues. Located on the upper sides of the tongues (8), i.e. the side facing the ground or mountain, is a cover plate (10) whose length extends over the free end of the tongues (8) and whose width extends over the lateral edges of the cutter rear end (4).

Abstract: The inverted-T gate MOS transistor is made as follows: on a substrate (21) a gate oxide layer (22), polySi layer (23) and metal layer (24), pref. of W or Ti and to act as a shielding layer, are deposited in this order. A polySi gate is defined and the polySi layer layer etched back pref. until the gate-oxide layer shows, and then used to mask the implantation of lightly doped drain and source regions (25). A second poly-Si layer (26) is deposited and then a low temp. oxide layer, pref. with a high dielectric constant, pref. Ta2O5 from which oxide spacers (27A) are formed adjacent to the sides of the poly-Si gates. The uncovered regions of polysi are etched away and a high concn. implantation carried out to give low resistance source- and drain-regions. USE/ADVANTAGE - The process is simpler and capable of higher yield than current processes. The Nmos process claimed can also be used as part of a Cmos process. The process is easily controlled and uses no additional masking steps. No unnecessary layers inside the gate structure are used as in some current techniques.

IPC: C08L31/00
Filed: 1992-03-28
Abstract: Aqueous polymer dispersions containing vinyl ester polymers or vinyl ester copolymers and having reduced contents of undesired residual monomeric vinyl esters and possibly acetaldehyde as a consequence of the preparation are prepared from corresponding starting dispersions, as obtainable by conventional polymerisation or copolymerisation methods from ethylenically unsaturated monomers, by selective alkaline hydrolysis (saponification) of the alkaline-hydrolysable residual monomeric vinyl esters in the dispersions and preferably simultaneous removal of the acetaldehyde and unhydrolysed residual monomeric vinyl esters from the aqueous dispersions by distillation. The residual-monomer-free polymer dispersions are used as binders in low-emission or emission-free aqueous preparations, for example for paints, coatings, plasters, adhesives, paper sizes (sizing agents), fibre non-woven binders, textile auxiliaries, etc, in particular for interior applications or in closed spaces.

Title: Optical polariser, e.g. for optical fibre laser gyro - has partially flattened sections separated by unflattened, curved sections
Inventor: NEUKIRCH MICHAEL DIPL ING
IPC: G01C19/72
Filed: 1992-06-19
Abstract: The optical polariser consists of an optical fibre (1) partially flattened to its core. At the cut away section the fibre is covered with a material which damps light of one polarisation direction.
