Title: Compsn. contg. insect repellent extract of Azadirachta indica
Inventor: REMBOLD HEINZ PROF DR
IPC: A01N65/26
Filed: 1995-09-04
Abstract: The compsn. contains an extract from the leaves, bark or seeds of the neem tree, Azadirachta indica.  The compsn. is useful as an insect repellent in creams, lotions, sprays, shampoos, water emulsions, or absorbed onto a carrier which allows it to evaporate at room temp. i.e. 30-60 deg.C (claimed). Also claimed is its use as an antiviral agent and an acaricide.  Unlike synthetic insecticides (e.g. pyrethrums and toxins obtd. from Bacillus thuringiensis), this compsn. does not induce resistance in the insect populations, since it repels rather than kills insects. It acts by hindering the reproduction and development of almost all known insect species, and is effective at concentrations measurable in parts per million.

Patent DE-19623541-A1 (DE)
Inventor: GREUTER FELIX DR
IPC: H02H9/04
Filed: 1996-06-13
Abstract: A first MOV surge arrester (4) e.g. for a high-voltage system, has a conventional voltage limit, at which it becomes conductive, that lies just above the phase voltage of the system and forms a first current path with a series-connected impedance (6), the value of which (Z) in an initial state is negligible. If the first MOV surge arrester (4) is threatened with overload owing to a prolonged surge and consequent excessive energy absorption by the surge arrester, a further current path which runs through the first MOV surge arrester (4) and a second MOV surge arrester (5) parallel to the impedance (6) and which is connected in series with it will be switched over by raising the impedance (6) value. In this way leakage current through the first MOV surge arrester (4) and thus the energy absorption of the arrester are reduced to normal values. The circuit enables substantial reduction in the level of protection and system insulation may therefore be designed to substantially lower values. The impedance (6) may be formed as a PTC element, a safety fuse or a switch controlled by the energy absorption or temperature of the first MOV surge arrester (4), possibly with a parallel high pass filter and a parallel spark gap.
Patent DE-19626113-A1 (DE)
Inventor: DUETTING KASPAR
IPC: H01S5/22
Filed: 1996-06-28
Abstract: Digital optical telecommunication uses optical semiconductor components having a transition region for the expansion of the mode field of a light wave in order to reduce losses when coupling to an optical fibre or an optical waveguide of a supporting plate. An optical semiconductor component (BE1; BE2) contains a deep ridged waveguide (RIDGE) with a surfacing (DS) disposed on a substrate (SUB). The ridged waveguide (RIDGE) has a first (MQW) and a second (BULK) waveguide centre. The first waveguide centre (MQW) contains one or more optically active semiconductor layers. In a first transition region (UB1) the layer thickness of the second waveguide centre (BULK) decreases along a longitudinal direction (L) of the ridged waveguide (RIDGE). As a result, a light wave guided in the optical semiconductor component (BE1; BE2) is diverted into the surfacing (DS) and substrate (SUB) semiconductor material surrounding the waveguide centre, whereby its mode field is expanded.

Patent DE-19710693-A1 (DE)
Title: Image recording method
Inventor: SAKAI KATSUO
IPC: B41J2/415
Filed: 1997-03-14
Abstract: The method involves using a toner carrier (107) with a counter electrode (108) and a flight control part between the toner carrier and counter electrode.  A voltage corresponding to an image signal is applied to the control electrodes which control the passage of toner (106) through several microholes onto the recording medium.  An image is formed on the recording medium, which is arranged between the flight control part and the counter electrode.  When no voltage is applied to the control electrodes to form an image, an electric field is continuously applied to produce an electrostatic force, causing the toner to be returned to an image carrier to pass to the medium, but to prevent further toner from leaving the toner carrier.
Patent DE-19711165-A1 (DE)
Inventor: JANISCH WOLFGANG
IPC: H01L29/423
Filed: 1997-03-18
Abstract: The aim of the invention is to design a contact arrangement for a planar, integrable semiconductor structure, said semiconductor structure being configured especially as a combination of vertical FET cells (8), in such a way as to produce a maximized duct cross section for closed FET cells (8) and an enlarged source-contact surface. To this end, all of the contact holes which are metallized for contacting the semiconductor layers and areas lie on a common horizontal plane and are configured as a recess which diminishes as it reaches the center. Said recess projects downwards to the lower part of the vertical extension of the layer forming the source (4) or to a depth of approximately 500 nm in the substrate (15) or the layer which is to be contacted. During production of the arrangement, the oxide layer (2, 3) on the substrate surface is opened locally during a first anisotropic etching step using one mask only, in order to create the contact holes for all the layers and areas which have to be contacted. In a second anisotropic dry etching step, a recess which diminishes in the center is then etched into the opened contact holes in a self-adjusting manner.
