Patent DE-4108610-A1 (DE)
Inventor: KIENZLER RAINER DR ING DR
IPC: H01L27/02
Filed: 1991-03-16
Abstract: A transmitter end stage for a data transmission system comprising at least one control unit and data transmission lines, in particular for a CAN bus system comprising at least one CAN controller and one CAN bus (CB), is characterized in that the individual switch elements of the transmitter end stage (18) are monolithically integrated. As a result of the special layout and circuitry of the individual elements (3, 5; R1, D1, T1; R2, D2, T2; D10; D20) of the transmitter end stage, the effects of interferences, for example short circuits in the data lines with respect to earth or the supply voltages, are reduced to a minimum. The special choice of the pre-drivers (3, 5) results in minimal delay times and therefore signals with high data rates can be transmitted.

Title: Optical distance measurement method - focussing laser or infrared light onto object and then onto position sensitive semiconductor controlling power transmitted to keep edge current constant
Inventor: KEGEL GUNTHER DR
IPC: G01S17/46
Filed: 1991-05-15

IPC: H01L21/20
Filed: 1992-06-05
Abstract: The production of quantum wire is complex. A simplified production process of quantum wires is disclosed which also entails a simplified production process of components provided with such wires. A monocrystalline layer (3) of semiconductive material is epitaxially grown on the surface (10) of a substrate (1) upon which is applied a masking layer (2), at the edge (21) of the masking layer (2). The monocrystalline layer (3) of semiconductive material has two mutually perpendicular outer crystalline surfaces (30, 31) which abut each other along the edge (21) of the masking layer (2). These crystalline surfaces (30, 31) define an edge (33) of the monocrystalline layer (3) which extends along the edge (21) of the masking layer (2). On these crystalline surfaces (30, 31) is grown a quantum-well layer (4) of another semiconductive material. The other semiconductive material is modified in an area (70) that extends along the edge (33) of the monocrystalline layer and that defines the quantum wire to be produced. Application in high-speed transistors.

Title: Electrical DC power supply - has capacitive energy store supplying load with reserve battery energy when voltage falls below threshold value
Inventor: SCHARF FRIEDRICH DIPL PHYS DR
IPC: H02J9/06
Filed: 1992-08-11
Abstract: The DC power supply (24, 28) is connected from time to time to a capacitor (12) used as an energy store, whose capacitance is such that a load (18) can be supplied with electrical energy for a preset time. An intermediary voltage converter (17) is connected in front of the load. There is a changeover switch (13) which switches in a reserve battery (15) when the capacitor voltage falls below a threshold value. This threshold point is established by a comparator (20) which triggers the switch relay. An LED (21) warns of the change in mode. The original power supply may be a solar-powered generator. The changeover switch can be manually operated rather than electronically operated. USE/ADVANTAGE - Uninterruptable power source, esp. as complement to solar generator. Reserve battery capacity, and therefore its size can be small, as capacitive store is rechargeable in short time.
Patent DE-4227620-A1 (DE)
Inventor: BERTOLDO GIOVANNI
IPC: E05F15/12
Filed: 1992-08-20
Abstract: The invention concerns a door, in particular a double-wing door, whose door-wings execute, during closing and opening, a combined translational and rotational motion about a vertical axis. The door is fitted with detachable means which enable the door to be used on emergency-exit and escape routes, i.e. when a manual force is applied from the inside on the door-wings, they are disconnected from the drive unit and can easily be opened by hand. So that the door does not remain open, however, the design includes switches or sensors which report any manual opening of the door to the control electronics which in turn sets the drive in operation in order to connect the door-wings automatically with the drive unit again.
