Patent EP-0036573-A2 (EP)
Inventor: STOFFEL AXEL
IPC: H01L21/3213
Filed: 1981-03-12
Abstract: A method is described for eliminating abnormalities in a polycrystalline silicon integrated circuit structure, such as a silicon gate field effect transistor structure. The layer (30, 40) of polysilicon is deposited on an insulator coating (24, 38) which may be the thickness of the gate dielectric. The polycrystalline silicon is delineated by lithographic techniques and a reactive ion etching process to form the desired conductor structure. A thickness of the polycrystalline silicon of the order of tens of nanometers is left upon the insulator coating (24) where the masking layer has openings. This thin coating of polycrystalline silicon is then thermally oxidized together with the exposed sidewall of the polycrystalline silicon in the areas under the opaque parts of the masking layer to form silicon dioxide on the sidewall of the polycrystalline silicon structures. A directional reactive ion etching of the silicon dioxide removes all silicon dioxide formed by the thermal oxidation step from the horizontal silicon substrate while leaving the silicon dioxide on the vertical sidewall regions. The method prevents the formation of a poor grade of silicon dioxide under the edges of the polycrystalline silicon conductor structure.

Abstract: An improved a power steering apparatus includes a fluid motor which is connected with a steerable vehicle wheel by a rack gear. The fluid motor has a piston with a relatively large head end surface area and a relatively small rod end surface area. In order to compensate for the difference in the head and rod end surface areas, actuation of a steering control valve assembly is resisted with a greater force when fluid pressure is being directed toward the head end surface area than when fluid pressure is being directed toward the rod end surface area. The force resisting actuation of the valve assembly is exerted by a spring assembly which includes a torsion bar disposed within a torsion tube. When the valve assembly is actuated to direct fluid pressure toward the relatively large head end surface area of the piston, both the torsion tube and bar are deflected. When the valve assembly is actuated to direct fluid pressure toward the relatively small rod end surface area, only the torsion bar is deflected (Fig. 1).

Abstract: The invention relates to a method for the preparation of highly heat-resistant relief structures with a base of polymers of heterocyclic structure by applying radiation-sensitive soluble polymer precursor stages in the form of a film or foil to a substrate, irradiating the film or foil through negative patterns with actinic light or by deflecting a light, electron or ion beam, removing the non-irradiated film or foil portions and, optionally, by subsequent annealing, as well as to the use of relief structures prepared in this manner. It is provided to use as polymer precursor stages addition products of cyclic carboxylic-acid anhydrides with hydroxyl group-containing compounds, where the hydroxyl group-containing compounds represent addition products of olefinically unsaturated mono-epoxides on carboxyl group-containing prepolymers of polyimides, polyisoindoloquinazoline diones, polyoxazine diones and polyquinazoline diones or on amino group-containing prepolymers of polyimidazoles and polyimidazopyrrolones or on hydroxyl group-containing prepolymers of polyoxazoles. The relief structures prepared by the method according to the invention are suitable especially for use as resists, surface coating materials and insulating materials.

Abstract: A process is described for the production of the proteolytic enzyme chymosin. The process involves cleaving chymosin precursor polypeptides such as methionine-prochymosin, preprochymosin and methionine-chymosin expressed from a host organism which has been transformed with a vector system carrying the relevant gene. The gene sequence of preprochymosin is given. The vector systems used are plasmids adapted for the transformation of either bacterial or eukaryotic host organisms. E. Coli and saccharomyces cerevisiae are specific examples of suitable host organisms. There is also described an oligonucleotide capable of being used as a specific hybridisation probe or transcription primer for mRNA containing the nucleotide sequence coding for chymosin. A microassay for chymosin activity is also described.

Abstract: A railway signalling receiver in which a signal carried by the railway lines is sensed and the sensed signal (11) is sampled (14), digitised (16) and subjected to a discrete Fourier transform operation Figure 3) which transforms the time domain samples into the frequency domain. The frequency content of the signal may then be examined in order to identify the original signal or to decode the information carried. The signal may be a frequency shift keyed carrier signal. A technique of maintaining the safety of the system by discriminating against potentially confusingly similar ASK signals which can arise spontaneously in electric traction territories. A technique of digitally heterodyning down a carrier signal so that the transform operates on the lower sidebands frequencies in order to maximise efficiency of the transform calculations is also described (Figure 3). The receiver is useful as a jointless track circuit receiver (Figure 3) and also in a part of the train borne equipment of an automatic train protection system (Figure 4).

Abstract: A multicoordinate sensing head includes a housing which defines a sensing pin opening which is covered by a rigid plate. The plate defines at its center a cup bearing which pivotably mounts a ball. The ball defines a diametrically oriented bore sized to slide over a sensing pin. The plate is mounted to slide radially with respect to the housing in a circular recess defined by the housing. The outside diameter of the plate and the dimensions of the recess are matched in such a way that the sensing pin is free to move laterally when tilted. During such tilting the ball surrounding the sensing pin pivots in its bearing and the sensing pin opening remains covered in all cases.

Abstract: An internal bore gauge comprises a body portion 12 having radial slots 20 carrying a pair of diametrically opposed anvils 22 capable of controlled movement in the radial direction, the anvils 22 having rounded end faces 36 of radius of curvature close to the radius of the bore being measured. By having only two anvils, and give the bore contacting faces of the anvils a radius of curvature close to the radius of the bore being measured, range of movement of the anvils, and therefore the range of measurement of the device, can be increased since any tilting of the gauge in the bore is compensated for by the curved faces of the anvils.
