Abstract: The invention relates to the mounting of a movable member such as an optical mirror (3) by bridges (4-7) between a pair of supports (1,2). The supports (1,2), bridges (4-7) and mirror (3) are integrally formed from a silicon substrate. A pair of electrically conductive paths (8,9) are formed by doping or metallising portions of the assembly so that by passing controlled currents through the paths, thermal expansion of parts of the paths will cause deflection of the mirror (3). The assembly is particularly useful for deflecting optical beams.

Abstract: The mass spectrometer timing the flight paths uses a reflector to guide ions from an ion source towards a detector. Incoming ions (35) pass through two spaced apart ring shaped braking electrodes (27,28) and a ring shaped focussing electrode (30) before approaching the reflector electrode (29). Between the focussing and reflecting electrodes (30,29) are three spaced apart ring shaped linearising electrodes (20,21,22). The front electrode (27) has a larger hole diameter than the braking electrode (28). The focussing electrode (30) is at a higher  potential than the linear increase in potential between the braking electrode and reflector electrode.

Abstract: A process is disclosed for improving the isolation between semi-oxide insulated devices, formed on mesa structures. In the fabrication of such devices, a silicon substrate is provided. Patterned regions of one type of conductivity are formed in a major surface of the substrate and an epitaxial layer of silicon is formed on the substrate over the major surface. A patterned mask layer is formed on the epitaxial layer and is etched to expose portions of the epitaxial layer. The exposed portions of the epitaxial layer are removed to form the mesa structures, which overlie the doped patterned regions. Regions of opposite conductivity, called channel stops, are then formed in the substrate between the patterned regions. After filling in the areas between the mesa structures with a field oxide, the devices (bipolar or MOS transistors) are formed on the mesa structures. The process of the invention utilizes as a mask structure a mask having a combination of properties (composition and thickness) related to the subsequent processing. The mask permits use of an anisotropic etchant to define the mesa structures and to undercut the mask. An oxide layer is formed on the side walls of the mesa structures and on those portions of the substrate exposed during the mesa-defining step. Those portions of the oxide layer underlying openings in the mask structure are removed to expose portions of the substrate, which encompass regions between the doped patterned regions. The channel stop dopant is introduced into the regions between the patterned regions.

Abstract: DNA encoding the gene for the synthetase enzyme capable of generating delta (L- alpha -aminoadipyl)-L- cysteinyl-D-valine (ACV) from its constituent amino acids was obtained from several penicillin and cephalosporin producing organisms, e.g. Penicillium chrysogenum and a Flavobacterium species. The DNA was used to prepare recombinant vectors comprising the ACV synthetase gene and hosts transformed with such vectors. The ACV synthetase gene can form part of a gene cluster comprising other genes involved in  beta -lactam biosynthesis and the production of penicillin by expression of the entire biosynthetic gene cluster for the synthesis of penicillin from primary amino acids is described. Suitable hosts in which expression can take place include heterologous hosts which are naturally non-producers of penicillin.

Abstract: Chromogenic substrates for the detection of hydrolyzing enzymes, processes for the preparation of these chromogenic substrates and the use of the chromogenic substrates. The quantification of hydrolyzing enzymes for diagnostic purposes has to date been carried out by determination of the amounts of a fluorescent or highly absorbent chromogenic dyestuff liberated in the hydrolytic reaction, detection of which has in part been possible exlusively by instruments or in the neutral to alkaline pH range. After enzymatic hydrolysis, the chromogenic substrates according to the invention lead to highly sensitive and specifically measurable signals regardless of the pH range. Azo dyestuff compounds with the general formula A-N=N-B (OR) in which A) and B) have the meanings given in claim 1 and R) is a radical which can be liberated by enzymatic hydrolysis, excluding a carbonyl radical, are provided. After enzymatic hydrolysis, highly sensitively and specifically measurable signals are obtained regardless of the pH range. The azo dystuff compounds mentioned are used for the detection of hydrolyzing enzymes, in particular glycosidases, phosphatases and sulfatases.

Abstract: A direct injection internal combustion engine, especially an Otto engine, is provided with layered lean operation and internal exhaust-gas recirculation. An exhaust-gas aftertreatment for reducing Nox using an Nox storage catalyst is also provided. This combination is to achieve the highest possible exhaust-gas recirculation rates with the lowest HC and Nox emission values. A tumble flow is provided for the incoming fresh gases, which may contain recirculated exhaust gas from external exhaust-gas recirculation. The swirl axis of the incoming fresh gases therefore extends substantially crosswise to the piston movement. This results in an emissions-reducing, optimal mixture inside the cylinder during the layered lean operation.
