Patent DE-19651003-A1 (DE)
Title: Large single crystal layer production
Inventor: NICKEL NORBERT DR RER NAT
IPC: C30B1/08
Filed: 1996-11-29
Abstract: A process for producing a single crystal layer from amorphous or polycrystalline semiconductor material on an amorphous foreign substrate involves forming a nucleation centre point by laser melting with a single laser pulse of preset spot size and then linearly advancing a resulting solidified small crystallisation front by alternate steps of changing of the radiation location in the submicron range and emitting further laser pulses. The novelty comprises a further process stage of (a) matching the laser pulse spot size (9) to the long edge length (8) of the elongated single crystal (6) formed in the preceding stage; and (b) linearly advancing one or both long edges of the crystal as a broad crystallisation front (10) by alternate steps of changing of the radiation location in the submicron range and emitting further laser pulses (3) having the broadened spot size (9). Also claimed is an apparatus for carrying out the above process.

Title: Fluid friction coupling for vehicles
Inventor: REEB WOLFGANG DIPL ING
IPC: F16D35/02
Filed: 1997-01-28
Abstract: The fluid connection consists of one or more channels (10,11) issuing into the radially outermost area of the working chamber (7) which is linked to the coaxial reserve chamber (9) radially outwards. The viscous working fluid is solely responsible for pressurising the reserve chamber, or alternatively this is performed by pressure cylinders whose pistons are powered controllably by a coolant-loaded expander. The pistons can also be driven off a cam triggered plunger, or again by electric motor complete with a drive shaft designed as spindle working within the piston. The partition (8) between work and reserve chambers (7,9) is drilled to give an equalising hole, and the reserve chamber consists of a ring of cylinders which enclose the working chamber and whose pistons are powered by electromagnets which enclose the working chamber and whose pistons are powered by electromagnets which move the pistons into their draining position from their spring-loaded filling position.
Patent DE-19703210-A1 (DE)
Title: ABS brake control system for motor vehicle
Inventor: WATANABE TAKASHI
IPC: B60T8/1764
Filed: 1997-01-29
Abstract: The ABS brake control monitors the wheel slip during braking and applies corrective control to the brake pressure to optimise the braking force. The control computes a value for the road grip and uses this value to control the front and rear brakes.  For an improved control, the rear brake control is applied after a computed time delay. The control uses the varying road grip value for a responsive braking control. The delay in applying a particular road grip value to the rear brakes is computed from the actual road speed in force at a particular instant.
