Patent DE-19919872-A1 (DE)
Inventor: ERSOY METIN
IPC: B60T13/567
Filed: 1999-04-30
Abstract: The invention relates to a brake servo unit (1) for a motor vehicle, comprising a brake servo unit housing (2), at least one vacuum negative-pressure chamber (13) and at least one additional pressure chamber (14), which can be prevailed upon by an ambient pressure whenever an actuating pedal for the brake assembly of the vehicle is operated. The negative-pressure chamber and the pressure chamber are separated from one another by a displaceable piston (9). According to the invention, the brake servo unit has at least one additional vacuum negative-pressure chamber (17) which can be connected to the pressure chamber, using a shifting device (18). The inventive configuration provides the necessary negative pressure, in order to operate the brake servo unit for a sufficient number of braking procedures, even when used with motor vehicle engines which can no longer provide the necessary negative pressure for normal operation of a brake servo unit. The inventive configuration can be constructed within the construction space available in conventional brake servo units and thus requires only minimal additional costs.

Patent DE-19922653-A1 (DE)
Title: Focussed ion beam control method for semiconductor device manufacture
Inventor: KECKLEY DAVID M
IPC: G01Q60/00
Filed: 1999-05-18
Abstract: The procedure produces a real time detector signal when a focussed ion beam is applied to the structure. It compares the signal with a reference curve showing an expected material limit. Beam focus on the device is ceased when real time signal shows characteristic corresponding to area of material limit. A focussed ion beam is directed on the structure of a semiconductor device to be worked. When the focused ion beam is applied to the structure, a real-time detector signal (1500) is created by detection secondary electrons, emitted when the beam is applied to the structure. The signal is compared with a reference curve (1200) which has a range indicating the expected material limit and a stop marking (1205) in the range. The beam focus on the structure is stopped when the real time signal shows a characteristic, which corresponds, to the range of the reference curve.

Inventor: HOERBER JOHANN KARL HEINRICH
IPC: C40B40/06
Filed: 1999-08-17
Abstract: The invention relates to a method of detecting analytes in a sample. According to said method, analyte-specific binders (15) are immobilized on a plurality of detection fields (5, 7) on one of the planar faces of a disk-shaped substrate (3). The sample is contacted with said detection fields (5, 7) and the presence or/and the quantity of the analytes (17) to be detected is determined by optically evaluating the detection fields (5, 7). According to the invention, a substrate (3) is used that is produced from an optically transparent material. The detection fields (5, 7) are arranged along at least one spiral line (27) distributed across the substrate (3). After the sample has been contacted with the detection fields (5, 7), a reflecting layer (21) is flatly applied on the substrate (3) on the planar face carrying the detection fields (5, 7). Alternatively, a magnetic read-out of the substrate can be made instead of the optical read-out.
