Patent DE-4317324-A1 (DE)
Title: Emergency running device for motor vehicle tyres
IPC: B60C17/02
Filed: 1993-05-25
Abstract: At present there are tyres with rims which when they burst or suddenly lose pressure drop down onto the rim flange and make the motor vehicle unstable. It is possible for the tyre to be destroyed. This patent prevents the tyre dropping onto the rim flange in the case of a sudden loss of pressure. This can be achieved by means of a solid rubber tyre around the rim, by means of a second 2-chamber tyre which is higher in each case than the rim flange or a folded air bag (made of special material) around the rim which then inflates to the level of the tyre when there is a sudden loss of pressure. This can all be controlled by: controller, sensor, control unit and air generator. The system can also be used for monitoring or keeping constant the air pressure in the tyre. The invention can be used in all vehicles which have pneumatic tyres. <IMAGE>

Title: Method and device for coating spectacle (ophthalmic) lenses (eyeglasses) in a vacuum
Inventor: BEISWENGER SIEGFRIED DR

Abstract: In a method and a device for coating spectacle lenses (1, 2) made from plastic or mineral glass and having at least one strongly bonding (adhering) and scratch-resistant (scratchproof, marproof) reflection-reducing layer in a vacuum, the spectacle lenses (1, 2) are exposed to a low-pressure plasma in the presence of at least one layer-forming material in the gas phase. Two spectacle lenses (1, 2) are preferably held at a distance from one another by means of an essentially annular chamber part (5), and this produces between the spectacle lenses and the chamber part a plasma-filled space (8) into which the layer-forming material is introduced. In a device suitable for this purpose, a further, approximately rotationally symmetrical chamber (7) is arranged in a vacuum chamber (17) and is provided on opposite sides in the direction of the rotation axis (A-A) with insertion openings (3, 4) for one spectacle lens (1, 2) each, and has on diametrically opposite sides with respect to the rotation axis (A-A) an inlet opening (9) for the decomposable gas and an outlet opening (12) for the residual gas. <IMAGE>

Patent DE-4338187-A1 (DE)
Title: Light-emitting semiconductor component
Inventor: BOMMER ULRICH DIPL ING
IPC: H01L33/00
Filed: 1993-11-09
Abstract: In the case of a light-emitting diode, various absorption mechanisms are known for the emergence of light from the interior of the semiconductor. Thus, absorption or reflection of the light beams from the metal contacts takes place, which leads to increased losses. According to the invention, a semiconductor zone is therefore proposed, which extends in the central region of the front contact of the diode from the surface into the top layer and has a smaller lateral extent in comparison with the contact. This semiconductor zone and the semiconductor layer through which this semiconductor zone extends are of the opposite conduction type, so that no flow of current is set up in the region between this semiconductor zone and the p-n junction. The flow of current can therefore concentrate only on the edge region of the contact, so that the absorption losses are thereby reduced. The same effect is also obtained according to the invention in that, instead of the oppositely doped semiconductor zone, an oxide layer is arranged under the contact or the current conductivity is reduced in this region by ion implantation.

Title: Lock-up control system for an automatic transmission
Inventor: IIZUKA NAONORI
IPC: F16H59/18
Filed: 1994-05-11
Abstract: Depending on a signal representing the instantaneous throttle-valve opening angle, which is recorded by a throttle-valve opening-angle sensor (100), and a signal representing the instantaneous vehicle speed, which is recorded by a vehicle-speed sensor (120), a lock-up control device (140) determines whether a lock-up clutch should be engaged or disengaged. On completion of the abovementioned process of determination, the control device (140) outputs a certain signal to an electromagnetic operating valve (19). If the lock-up clutch has been disengaged, this state is maintained. If, on the other hand, the lock-up clutch was engaged, the control device (140) determines whether this state is maintained or whether a lock-up clutch disengagement procedure as a function of the instantaneous throttle-valve opening angle is chosen. In particular, the control device (140) chooses a procedure such that the force of engagement of the lock-up clutch during idling of the motor vehicle is reduced very rapidly, that it is reduced slowly when the throttle-valve is in a central position and is reduced slowly in a suitable manner when the throttle-valve opening angle is large. In such a control system, a ... Original abstract incomplete. <IMAGE>
