Title: Circuit to ensure balanced positive and negative voltage supply e.g. for operation amplifier
Inventor: KIM YONG-HO
IPC: H02M3/00
Filed: 1996-04-26
Abstract: A voltage balancing circuit for a power supply with positive and negative rails for two loads in series, earthed at the centre node has a reference voltage source equal to half the total voltage of the supply, two equal capacitors (c1,c2) in series across the supply with the  node between the capacitors earthed and a comparator (21) for the reference voltage against the voltage at this earthed node, giving an error signal. An amplifier (tr1) takes the error signal and acts to minimise it by supplying the required extra volts so that the positive rail voltage equals the inverse of the negative rail voltage.

Title: Optical system evaluating quality of fluid distribution onto test piece, e.g. medical test strip
Inventor: BOLDUAN FRANZ DR
IPC: G01N35/00
Filed: 1996-07-16
Abstract: An analysis system evaluates test pieces (T), determining whether a sufficient quantity of test fluid has been supplied evenly to the delivery zone (A). It comprises a pair of light sources (L1, L2), which illuminate separate or only partially-overlapping regions (B1, B2) of the delivery, or evaluation zone of the test piece. A controller activates the sources separately. A sensor (D) receiving light reflected from or transmitted by the zone produces an output corresponding to the light intensity received. The evaluation unit (E) measures light intensities resulting from individual illumination by  first and second sources in succession. Measurements are evaluated, comparing the results from the regions. The system determines whether the difference between them is sufficiently small. The difference or relative difference is compared with a set threshold. Above the threshold an warning is given, below it, the result is given. Diffuse reflected radiation is detected. The illuminated regions of the delivery or evaluation zone are the same size. Two light sources are placed in a common plane parallel to the evaluation zone. The light sources correspond in their spectral intensity distribution and their cone of illumination. The optical paths for each source of illumination, the evaluation zone and the sensor are geometrically identical. The delivery zone is covered by a net with square or rectangular mesh. The line connecting middle points of the illuminated regions makes an angle of 45 deg  with the net threads.
Patent DE-19633915-A1 (DE)
Title: Fault analysing unit for use in semiconductor memory testing system
Inventor: OHSAWA TOSHIMI
IPC: G11C29/00
Filed: 1996-08-22
Abstract: The unit has a fault memory, for storing fault data related to the memory to be tested, under an address, selected by address data from a memory test system, if a fault signal is produced by a logical comparator in the memory test system. An OR circuit prepares input data for the fault storage on the basis of an OR logical linking, between the fault signal from the logical comparator and data, which is stored in the fault storage, under an address selected by the address data. A recording release control (24) produces a recording release signal, which is to be supplied to the fault storage on the basis of the fault signals from the logical comparator. An AND circuit is fed with the fault signal from the comparator and with the data, which is stored in the data memory, under an address selected by the address data, in order to transmit the fault signal, if the data from the fault storage indicates that the fault data under the address is not yet stored. A fault counter (23) counts the number of fault signals, which are transmitted from the AND circuit in the course of a test of the storage to be tested, by the semiconductor storage test system.
Patent DE-19634125-A1 (DE)
Title: Junction layer in semiconductor component manufacturing method for integrated semiconductor module
Inventor: CHUNG HENRY WEI-MING
IPC: H01L21/768
Filed: 1996-08-23
Abstract: The method initially involves depositing a metal layer on a barrier layer surface followed by the formation of a protective layer on the metal layer surface. Junction layers (224) are then formed over a base layer (202) with at least one through aperture (206) filled with packing (212). On the base layer is deposited a barrier layer (210, 214). A metal layer (216) is deposited on the barrier layer surface, and a protective layer (222) is formed on the metal layer surface. The metal and protective layers are structured to define a conductive structure on the barrier layer surface. An etching stop layer (226), coinciding with at least one metal conductor (224a-d) is formed and its selected sections are removed for exposing the surface of the conductor protective layer, but leaving spacers (228aa-db). After removing sections of the barrier layer a dielectric layer (232) with through contacts is formed. Selective etching completes the process.

Title: Rotation- or spin-suppression control for vehicle
Inventor: KAWAGUCHI HIROSHI
IPC: B60T8/24
Filed: 1996-08-23
Abstract: The vehicle is fitted with monitors on the wheels and a control system which detects the onset of slewing, generated by steering and road grip, and especially found during oversteer. The individual wheels are braked to counter the slewing. The braking is in a simple mode up to a set level of slew, and in an interactive mode for higher slew movements. The two modes of control provide a simple stability control for most situations and a more complex control for higher risk conditions. The control determines a lateral slip value for each wheel to compare with stored values in the processor control.

Patent DE-19729479-A1 (DE)
Inventor: STEINER MICHAEL DIPL ING
IPC: G05F1/44
Filed: 1997-07-10
Abstract: The method involves combining voltage pulses (U1,U2) of first and second converters with first and second degrees of modulation (m1,m2) so that a common voltage pulse (U1+U2) without gaps is produced. Preferably, during generation of the pulse width modulation using an undershoot method, the carrier signal of the first converter is shifted through an angle alpha with respect to the unchanged carrier signal of the second converter, where alpha is + or - half the sum of the degrees of modulation times 180 degrees. The combined voltage pulses are symmetrical to the previous and following combined voltage pulses. The carrier signals of the first converter with the first modulation degree are shifted by a first angle and the carrier signals of the second converter with the second modulation degree are shifted by a second angle.

Patent DE-19736580-A1 (DE)
Title: Acoustic gas analyzer with pressure compensation
Inventor: MAYER HUBERT PROF DR ING
IPC: G01N29/036
Filed: 1997-08-22
Abstract: The analyzer continuously determines  the mixture components of binary or quasi-binary gas mixtures, whose components are of known types. A quantitative analysis is performed. The speed of sound in the gas mixture and the vibration frequency of an acoustic oscillator, which is proportional to it, are used to determine the gas composition. The influence of pressure is reduced using a resonance chamber stimulated to resonance. The  resonance chamber is coupled so that a standing wave is set up in it. The length of the chamber is set, so that the primary frequency stimulates the chamber to resonate.  The secondary frequencies produced by the resonance chamber are independent of the pressure at the in and outlet of the primary oscillator, so pressure compensation is possible.
