Patent DE-4040303-A1 (DE)
Inventor: TUTZAUER RENE
IPC: B61F3/16
Filed: 1990-12-17
Abstract: The invention concerns independent-wheel running gear for rail vehicles, especially for local railway lines, consisting of a running gear frame (1) maintained in relationship with the vehicle body (3) via linking rods (2), independent wheels (5) horizontally pivotable in bearing cages (7) in the running gear frame (1) about a main axis (4) and air springs (6) suspending the vehicle body (3) with respect to the running gear frame (1). It is the purpose of the invention to provide an independent-wheel running gear for rail vehicles with loose wheels in which the pivot angle needed for the radial adjustment of the independent wheels (5) in curves is measured and transmitted to the wheel and the wheel is correspondingly adjusted, whereby, with the aim of economical, simple construction, the necessary driving and braking assemblies are arranged in such a way that the running gear operates safely. According to the invention, this aim is achieved in that a sensor (12) scanning the rail is fitted on each bearing cage (7) in front of and behind each wheel contact point controlling an adjusting cylinder (13) setting the deflection of the independent wheel (5) in accordance with the measured rail curvature via a regulator.

Title: Silicon@-on-insulator layer Getter process - produces directed redistribution of heavy metal contaminations out of active areas of SOI layer into areas acting as lateral dielectric insulation
Inventor: FISCHER ARMIN DR
IPC: H01L21/265
Filed: 1991-08-27
Abstract: The method involves forming a polycrystalline silicon structure in an SOI layer connected to an insulator layer and surrounding it completely by mono-crystalline, electrically active layer elements. The zone melting recrystallised, implantation-sepd. or bonded SOI substrate is selectively structured by ion implantation, amorphised, and subsequent high temp. treated into structural element-active, mono-crystalline and Getter-effective dielectrically insulated polycrystalline planar areas. Before the zone melting recrystallisation on the polycrystalline layer, a reflection layer matched to the lateral insulation pattern is applied, which leads in the recrystallisation process to local temp. modulation in the melting zone, and to formation of recrystallised mono-crystalline silicon zones and non-recrystallised polycrystalline Getter/insulation areas. USE - For Getter recrystallised, implantation-sepd. or bonded silicon-on-insulation layer production.

Title: Chrominance signal correction circuit for multi-analogue component signals - provides delayed chrominance interpolation or clamped signal to luminance signal processing stage to prevent cross-colour effect.
Inventor: CHO HYUN-DUK
IPC: H04N9/64
Filed: 1992-09-28
Abstract: The chrominance signal correction circuit is used in a video processing circuit with a luminance signal processing stage. The stage provides a luminance component within a binary coded video signal and a luminance interpolation filter for providing a luminance signal.
