Patent DE-19703223-A1 (DE)
Title: Electrode manufacturing method for semiconductor device
Inventor: BYUN JEONG SOO
IPC: H01L21/28
Filed: 1997-01-29
Abstract: The manufacturing method involves forming an insulation layer on a semiconductor substrate (11). A wolfram silicide layer (13) is formed on the insulating layer. Impurity ions are implanted in the wolfram silicide layer to form an impurity region in a lower region of the wolfram silicide layer. The method further involves carrying out a heat treatment of the substrate on which the wolfram silicide layer is formed. A second insulating layer is formed on the wolfram silicide layer. The layers are then structured to form a gate electrode in a given part of the substrate. Second impurity ions are implanted in the substrate. The gate electrode is used as a mask to form the source and drain regions.

Patent DE-19754220-A1 (DE)
Title: Vehicle collision detection method
Inventor: HERRMANN THOMAS
IPC: G01S13/931
Filed: 1997-12-06
Abstract: The method involves emitting a frequency modulated wave from a vehicle. A wave reflected from the object is received. The received wave is mixed with a component of the instantaneous emitted wave and a mixed signal is generated. The frequency of the mixed signal is a measure for the distance of the object from the vehicle.  The mixed signal is filtered for further processing using a filter with a frequency response which enables the amplitude of the filtered mixing signal to take on different values with a distance change between the vehicle and the object. A temporal distribution of amplitude values of the filtered mixed signal is provided. The distribution is compared with stored distributions of amplitude values and a side displacement is determined between the vehicle and the object.

Inventor: MEYER HELMUT
IPC: B60P1/64
Filed: 1998-05-16
Abstract: The rear of the vehicle has a U-shaped frame into which the container is located by backing the vehicle onto the container. A top spreader (45) lifts the container and drops it onto two roller tracks (44) which are moved under the edges of the container.
