Patent DE-4306565-A1 (DE)
Title: Method for producing a blue-sensitive photodetector
Inventor: ARNDT WOLFGANG
IPC: H01L31/0216
Filed: 1993-03-03
Abstract: The inventive method is primarily distinguished by the following steps:   - before an ion implantation is carried out there is constructed on a substrate a dielectric scattering-layer arrangement which has at least one oxide layer and a thickness such that the maximum of the implanted ions is located inside the layer arrangement; and - post-diffusion is carried out in such a way that the substrate does not oxidise any further.   The result of these measures is that, apart from a very narrow segregation region, the dopant concentration within the semiconductor substrate keeps decreasing in the direction of the pn junction, this resulting in an electric field which conducts in the direction of the pn junction essentially all charge carriers which were generated in the region between the surface of the substrate and the pn junction. A quantum yield is achieved thereby in the short-wave range which lies significantly above that yield which could be obtained by means of conventional photodetectors.

Title: Threaded nut for quick fit on threaded bolt - has three dimensional closed polygon drawn from wire like strip material with side faces for engagement by tool
Inventor: KRUEGER HELMUT
IPC: F16B37/12
Filed: 1993-03-11
Abstract: The side faces extend parallel between a top face (1)  and similar sized bottom surface (2) parallel to same.  The top face and base are alternately provided  with radially inwardly aligned curved indentations (thread curves 9 to 14) which protrude from the side faces (15 to 20).  The apices of these indentations lie on a curve corresponding to the core diameter of the threaded bolt and are angled according to the thread pitch of the bolt. First the nut is placed on the threaded bolt so that the apex adjoins a thread flank.  Central pressure is applied to the outer area of the thread curve in the axial direction of the bolt. USE- For screw connections requiring only a slight tightening moment.

Title: Method and embodiments for the prevention of cavitation processes in an injection pump with bevel edge control
Inventor: MILOJEVIC RADISA
IPC: F02M55/00
Filed: 1993-04-28
Abstract: In order to prevent cavitation processes in an injection pump with bevel edge control, the lines of the feed system are designed so that the fuel forced in whilst the pump piston is ascending flows in concentric spaces in the manner of a jet in such a way that a columnar displacement of the liquid volume in the feedlines and suction chamber of the injection pump is avoided, sufficient fuel remaining outside the jet to be then able to flow in free of cavitation in the suction phase of the pump piston. For performing the method, the injection pumps in the feed system are connected in series, the lines of the series connection running in a straight line and having an enlarged cross-section. In conventional systems an apertured disc is used for producing the fuel jet in the areas where fuel flowing at high velocity is sharply deflected or can produce a dynamic pressure.

Title: Process for producing a surround on decoratively covered mouldings
Inventor: GRUENHAGEL OTTO
IPC: B29C63/04
Filed: 1993-05-24
Abstract: Mouldings are provided with so-called 180 DEG  surrounds in order to protect the edge regions of the mouldings or to improve the appearance of these mouldings, which are used for example for interior linings of motor vehicles. The process presented creates a 180 DEG  surround in a fully automatic process by forming the surround in two successive working steps, placing around and applying. This is effected by special slides in the injection mould, an essential feature being that on the rear side of the moulding, the support part 2, there are formed special contours 3; 4, which have elevations 5 and depressions 6 which in turn form with the surrounded decorative material 1 mould cavities 14 into which thermoplastic material is injected through the openings 7 by means of suitable gating systems, preferably a hot runner needle shut-off mechanism, fill the said cavities and enter into an intimate bond with the surrounded decorative material 1. <IMAGE>

Title: Power supply unit for feeding a gas-discharge lamp
Inventor: ROTH HARALD DIPL ING
IPC: H05B41/288
Filed: 1993-10-16
Abstract: A known circuit for feeding a metal-halide lamp for an LCD television projector contains a switching transistor for a switched-mode power supply and four further transistors in a bridge circuit for feeding the lamp. There are particular requirements, in a power supply unit of this type, regarding the height of the power factor which indicates the fraction of the harmonics drawn from the network. According to the most recent regulations, this factor may not overshoot specific values. The object consists in designing a power supply unit of this type in such a manner that the outlay in terms of circuitry regarding transistors and the fraction of the harmonic currents in the network are reduced. The power supply unit contains a switched-mode power supply to whose output the series circuit of two capacitors (6, 7) and the series circuit of two switching transistors (12, 13) are connected. The lamp (8) is connected to the centres (c, d) of the two series circuits. In particular for feeding a metal-halide gas-discharge lamp for an LCD television projection device. <IMAGE>

Title: Polarisation scrambler
Inventor: NOE REINHOLD PROF DR ING
IPC: G02F1/035
Filed: 1993-10-28
Abstract: The object of the invention is to develop a known polarisation scrambler in such a way that the polarisation of the input wave can be arbitrary, i.e. elliptical, inclusive of the special cases of linear and circular. The scrambling is intended in this case, in principle, i.e. theoretically, to be complete; at best constraints and inaccuracies associated with production should not be able to detrimentally affect achieving this aim. The polarisation scrambler, having an input port (E) and an output port (A), has a retarder (R1) or two retarders (R1, R2) in chain connection, the angular coordinates (a1(t), a2(t)) of which are time-variable.
