IPC: B60G17/052
Filed: 1988-07-19
Abstract: In a known control device mechanical linkages are used for the axle load distribution of a leaf spring tandem axle of a commercial vehicle, which are not of compact construction and produce only limited axle load distribution. According to the invention a control device (10) is proposed for controlling a tandem axle of a commercial vehicle, as a function of the load, with a leaf spring power axle (14) and with a non-powered trailing axle (20) with both leaf and air springs, a pneumatic pressure cylinder (13) controlled as a function of the spring travel of the power axle (14) being provided, in which a constant control pressure corresponding to any spring travel of the power axle (14) is maintained by way of a pneumatic control line (5), the control line (5) on the pressure cylinder outlet side triggering the spring control device, especially the spring bellows (21) of the trailing axle (20). In the control line (5) first and second pressure switches (15) and (16) are also advantageously provided, which automatically control an assigned circuit for overload protection and an assigned circuit for a starting aid respectively. The trailing or lifting axle (20) may be manually operated. A control connection for a brake pressure control device (17) may also be provided in the control line (5). <IMAGE>

Title: Apparatus for the clamped mounting and twisting of a cylindrical workpiece
Inventor: KUCHENHART FRIEDRICH-WILHELM
IPC: B23Q7/04
Filed: 1988-10-11
Abstract: The apparatus serves for the clamped mounting and twisting of a cylindrical workpiece, such as the shank of a screw tap, which is to be inscribed by means of a laser beam. It comprises clamping strips and at least one counter-clamping strip which, offset relative to each other in the axial direction of the workpiece, hold the latter clampingly on the circumference. Displacement of the strips relative to each other causes rolling of the shank. The strips can simultaneously hold and twist a plurality of workpieces, so that the handling time for a workpiece is reduced.

Abstract: A device with sensors, which are provided for determining dynamically changing physical quantities, is described. Each sensor is connected via an associated channel to a signal processor, for combination or processing of dynamically changing binary signals which correspond to the physical quantities. Each channel which is connected to the signal processor has an adjustment device, which is provided to select the scaling information of the variables which correspond to the associated physical quantity, and can be, or is, adjusted to the range of dynamic change of the corresponding physical quantity.

Title: Rotating shaft seal assembly - has double-lipped profile with trapped lubricant to relieve seal wear
Inventor: KREUTZER SIEGMAR DIPL ING
IPC: F16J15/322
Filed: 1989-09-01
Abstract: The rotating shaft (1) is sealed by a shaped sealing lip (15) with one profiled edge constantly pressed onto the shaft and an inner edge (16) normally raised off the shaft.

Title: Thermal stabilisation of titanium-silicide film in IC - by formation of oxide-film on top by thermal oxidn. preventing redistribution during heat treatment
Inventor: OHSAKI AKIHIKO
IPC: H01L21/768
Filed: 1990-07-13
Abstract: The Ti-silicide film is formed as follows: a Ti-layer (12) of the required thickness is deposited on the relevant surfaces, pref.  on Si-surfaces. The film is heat treated in an ambient which inhibits oxidn. to form a Ti-silicide (TiSi) film, pref. -in an ambient of N2 or Ar. The unreacted Ti is then pref. removed.  At a temp. between 600 and 1000 deg.C for a given time, pref. 30 secs to 10 mins. for a fast heating process or several mins. to several hrs. for a slower process, in an ambient contg. oxygen to form an oxide on the surface of the Ti-silicide. An insulation film (8), pref. of P-doped or P- and B-doped silicate glass, is pref. formed on the Ti-silicide film by Chemical Vapour Depsn. (CVD) pref. before the oxidn. of the TiSi, and followed by a heat treatment to oxidise the TiSi. Also claimed is the use of the above process in the construction of a Si-gate MOS-transistor, for the gate-electrode and/or drain and source electrodes. Also claimed is the formation of  contacts to the source/drain regions by forming openings in the insulator film down to the TiSi-film, implanting impurities into the Si-substrate through the metal film and depositing a metallisation layer contacting the regions. Also claimed is the formation of a TiSi-film, using a similar process, on top of a deposited polycrystalline layer. USE/ADVANTAGE - The process allows the use of a Ti-silicide film in devices even though at least one heat treatment above 600 deg.C will be carried out after its depsn. This allows advantage to be taken of the low resistance of the Ti-silicide film. The process is carried out as part of a mfg. process of integrated circuits, including Drams where the contacts are made with polycrystalline Si part of which has been converted to Ti-silicide.
