Patent DE-19829531-A1 (DE)
Inventor: BRAUN ANDREAS
IPC: B62D5/06
Filed: 1998-07-02
Abstract: The invention relates to a power-assisted steering mechanism with hydraulic power assistance for motor vehicles, in which a steering shaft (15) fitted with a steering wheel (16) is connected to an input member of a steering gear (2). An output member of the steering gear (2) is connected to wheels (11) of the motor vehicle which are to be steered. Two working chambers (12, 13) of a servo-motor of a power amplification device can be subjected to a pressure medium in accordance with a torque acting in the area of the steering shaft (15)/or input member by means of a servo pump (19) via a steering valve. Two sensors (23, 24) for detecting an angle of rotation and a torque are positioned at the level of the steering shaft (15) or the output member of the steering gear (2). Once the steering wheel (16) has been released after a steering action has been carried out, the wheels (16) to be steered and the steering gear (2) can be returned to their initial position with hydraulic assistance. Both the extent and direction of the hydraulic power assistance and the resetting of the wheels (11) to be steered are controlled by a joint, electronically controlled electromagnetic valve (18). Moreover, to detect the steering force only a steering force and/or torque sensor (28) is provided for. This considerably reduces the control paths, thus resulting in very high steering precision.

Title: Hybrid drive for compressor
Inventor: SAKAI TAKESHI
IPC: F04B35/04
Filed: 1998-07-07
Abstract: A compressor for an air conditioning system in a vehicle is normally driven by the engine via a clutch. When the engine is not running the compressor can be driven by an electric servo motor via a one way clutch. This is a simple arrangement which effectively uncouples the electric drive when the compressor is driven by the engine. It reduces the torque shocks when the main clutch connects the drive to the compressor or removes it.

Title: Apparatus to apply differential and integral coatings to a substrate by PVD has a mask with structured openings for the coatings to give a single sample body for post-process analysis
Inventor: HOLLSTEIN FRANK
IPC: C23C14/04
Filed: 1998-11-02
Abstract: The apparatus to apply differential and integral coatings on to a substrate by physical vapor deposition, has a rectangular coating opening (6a, 6b) in the mask in two and opposing mask side surfaces. The height of the differential coating opening (6b) is smaller than or equal to the width of the mask side surface, using a flexible and continuous covering strip (1) as the mask. The height of the integral coating opening (6a) is larger than the width of the mask side surface, and preferably equal to the height of the sample body (2). The height of the mask is preferably equal to or larger than twice the height of the sample body. The inner cross section of the mask, from the center, matches the less developed cross section of the sample body, to give a contact-free and preferably vertical relative movement between the mask and the sample body. Each opening has the lower edge set preferably at half the mask height. At the start of a PVD coating, the sample body has its upper edge preferably at the center of the mask height. During the PVD coating, the sample body is moved by a drive in upward steps, and preferably the path length of the height of the differential window. The movement step frequency is selected so that, at the end of the PVD coating, the surface segment at the lower end of the sample body is free for PVD coating. Where the sample body is held in a fixed position, the mask or mask sections are moved by a drive in downward steps. The advance speed of the sample body, or the mask or parts of the mask, is not abrupt, during PVD coating. The mask can be prepared with only one opening, either as an integral or a differential opening. The mask is given a vertical movement, for each surface with an opening. During PVD coating, the apparatus is rotated round its longitudinal axis, preferably at a rotary frequency of 0.2-2.0 Hz. The sample body cross section is round, oval or quadrilateral. The process can use other deposition techniques and preferably chemical vapor deposition (CVD) or plasma polymerization processes.
