Title: Process for forming low-resistance contacts on at least two n<+>-/p<+>-type pre-ohmic zones of a large-scale integrated semiconductor circuit
Inventor: JIN DAE-JE
IPC: H01L21/768
Filed: 1989-03-16
Abstract: The invention relates to a process for forming a low-resistance contact on at least two pre-ohmic zones which are formed in a silicon substrate carrying a thick, insulating layer. The process comprises the following steps:   a) deposition of a polycrystalline silicon on the insulating layer,   b) carrying out an anisotropic etching step to open up the pre-ohmic zones, c) deposition, by sputtering, of a titanium which, after deposition, has electrical discontinuities on the vertical side walls of the zones which open there,   d) carrying out a silicisation of the titanium, and e) deposition of a metal silicide in order to prevent electrical discontinuities. In another embodiment there is used, instead of the titanium silicide, a titanium silicide applied by vapour deposition. A further embodiment comprises the following steps:     a) forming holes by anisotropic etching, b) deposition, in the holes and on the insulating layer, of a polycrystalline silicon,   c) deposition of a titanium by sputtering,   d) formation of a titanium silicide, and e) application of a metal silicide.

Patent DE-3913809-A1 (DE)
Inventor: UENO KATSUMI
IPC: B62D3/02
Filed: 1989-04-26
Abstract: The steering input shaft (3) drives an elliptical gear (4) which meshes with a further elliptical gear (6) on the output side. The smallest-radius part of gear (4) engages the largest-radius part of gear (6) in the straight ahead position so that a small steering wheel turn can produce a large steered wheel turn without making the steering too sharp in straight travel. The mechanism may form part of a power-steering system in which the output from gear (6) is amplified by the helical gear pair (31, 32), or by planetary gearing, before driving the power steering valve (9).   A counter-force mechanism (34) may produce a force which increases with increasing steering angle to prevent excessive steering angle and to assist the return of the steering wheel to the straight-ahead position. <IMAGE>

Title: Solids for uniform treatment with rising gas - descend in parallel internal compartments with overflow from decreasing heights
Inventor: FROELICH BERNHARD DIPL ING
IPC: F26B17/14
Filed: 1989-07-14
Abstract: A body of free-flowing solids, which during descent in a housing is to be treated by counter flowing rising gas, drops within a series of compartments (5, 6, 7, 8) sepd.  by internal partitions (24, 25, 26) adjustable in height, producing a series wherein the level of solids above the open compartment ends (9, 10, 11, 12) progressively lowers.

Title: Controlling clutch between engine and gearbox of vehicle - using clutch as bridging coupling of hydrodynamic unit or separation coupling and units detecting engine and drive RPM
Inventor: SCHWAB MANFRED DR
IPC: F16H61/14
Filed: 1989-07-26
Abstract: A slip regulating switch unit (1) is provided, and this determines the pressure for an adjusting drive (3) of the clutch (K) or the bridging coupling (WK).

The necessary coupling driven rpm (n.k,n.WK) for the slip detection is determined across the gear change (G.x) and determines the gear driven rpm (n.ab).  During the switching operation a virtual coupling driven rpm(n.Kvir) is determined and with this the slip regulation is further carried out or the pressure for the adjustment drive (3) of the coupling (K,WK) is varied depending on predetermined parameters. USE/ADVANTAGE - Esp. for car automatic drive.  Without knowledge of coupling driven speed, good switching quality is achieved without sacrificing comfort or turning engine.
