Title: Directional coupler for optical signals serving as a switch
Inventor: WIEDEBURG KLAUS DR
IPC: G02F1/313
Filed: 1981-09-30
Abstract: Directional coupler for optical signals serving as a switch and made using integrated technology, two closely adjacent light guides (A-A', B-B') which are arranged in parallel along a coupling section being mounted on a substrate, e.g. of LiNbO3 by means of Ti doping, and electrically controllable electrically conductive electrodes (E11...E24) being respectively mounted on the light guides along the coupling section, which electrodes pass on the light guided in the relevant light guide (A-A') directly (from A to A') or exchanged crosswise (from A to B') between the light guides, depending on the electrical control voltage (V1-V2) between the electrodes. The level of the control voltage can be reduced owing to the fact that at least two electrodes (E11...E14, E21...E24) are mounted in each case one behind another along the coupling section on both light guides in such a way that in each case one electrode (E11) on the first light guide (A-A') is situated opposite an electrode (E21) on the second light guide (B-B'), and that the two opposite electrodes (E11/E21, E12/E22,...), which form an electrode pair in each case, can be controlled separately by in each case another potential (V1 at E11, V2 at E21) of the control voltage (V1/V2). Furthermore, each electrode (E11) on the first light guide (A-A') is connected in an electrically conductive fashion in each case to an electrode (E22) on the second light guide (B-B'), which electrode (E22) belongs to another, preferably adjacent, electrode pair (E12/E22). <IMAGE>

Title: Semiconductor device and process for producing a semiconductor device
Inventor: MIYAGAWA MASAFUMI
IPC: H01L21/301
Filed: 1981-10-30
Abstract: The novel semiconductor device comprises a semiconductor wafer which has a groove (406) coated with a thin glass layer (410) for separating the semiconductor device into a multiplicity of semiconductor components. The semiconductor device can readily be separated along a raised section (407) on the floor of said groove (406) without the glass layer (410) cracking or breaking off. In the novel production process, the raised section (407) on the floor of the groove (406) is produced by creating a zone on the surface of the intended separation section of the semiconductor wafer which does not include the central region of the separation section, the etching rate of said zone being higher than the etching rate of the remaining region of the surface, and then etching the semiconductor wafer. <IMAGE>

Title: Shiftable safety coupling
Inventor: KONRAD MATHIAS DIPL ING
IPC: F16D27/118
Filed: 1981-11-13
Abstract: The object of the invention is to provide a safety coupling which is designed as a shift coupling and which is active at the same time as an overload coupling during the through-drive and, when the shift coupling is cut out, automatically brakes the drive train. The object is achieved in that the housing (126) of a friction coupling is connected to the shift coupling. Held frictionally in the friction coupling is a brake disc (127) which itself is connected firmly to a coupling hub (134) constituting the drive. When the shift coupling is cut out, a shift ring (113) equipped with a cam (123) is displaced into the effective range of a fixed stop (125) and is braked abruptly. The housing (126) of the friction coupling is braked together with the shift ring (113) and itself brakes the brake ring (127) and the coupling hub (134). <IMAGE>

Title: Hydraulic press with exchangeable rubber cushion
IPC: B21D22/12
Filed: 1981-11-13
Abstract: The invention relates to a hydraulic press for the forming of workpieces of metal, in particular metal sheets. The press has a rubber cushion and a solid die. The rubber cushion is arranged exchangeably in a receptacle. The solid die can be lowered by means of the press drive into the rubber cushion during the working stroke, deforming the workpiece, to be precise at specific pressures of over 1500 bar. The individual, exchangeable rubber cushions comprise a plurality of rubber cushion elements arranged in layers. Provided in this case are cushions of which the rubber cushion elements have a hardness of about 100 Shore and a thickness of about 200 mm, total cushion thickness 400 mm, and more. At least one of the exchangeable rubber cushions is, however, designed as a membrane cushion. Such a membrane cushion has a working membrane facing the workpiece and a liquid and/or quasi-liquid backing, the backing being supported in the receptacle. The solid die can be lowered, possibly by switching-over the press drive, into this membrane cushion at a specific pressure of 1000 bar or less. The liquid may be water, hydraulic fluid or the like. The quasi-liquid backing may be made up of a gel, for example based on polyurethane or silicone, which behaves virtually like a liquid upon lowering the solid die into the working membrane.
