Patent DE-3826396-A1 (DE)
Inventor: GRETHEN HARTMUT DR ING
IPC: H01L23/538
Filed: 1988-08-01
Abstract: In a functional component with a plurality of electrical functional elements closely aligned in linear fashion on a substrate and connected to integrated circuit (IC) components, manufacturing defects are virtually evitable as the distance between the functional elements decreases. By grouping the input lines (19) to the circuit components (5) by means of underlying connecting lines (13) to common contact connections (12) and by forming below the line (17) with the functional elements a return conducting layer (23) which extends to the contact connections (12) in order to return the sum of all the individual currents flowing through the functional elements, a functional component (1) is obtained from which defect-free segments can be removed and used individually or in groups. The functional component can be, for example, a thermal printing head, a light-emitting diode component or a line sensor.

Title: Method for detecting insulation faults on plastic-insulated electrical conductors
Inventor: DUESSEL KLAUS DIPL ING
IPC: G01R31/02
Filed: 1988-09-27
Abstract: To be able to distinguish spatially extended defects in the insulation (3) from relatively small defects (pore faults) in the manufacture of plastic-insulated electrical conductors (1), the measurement signal (10) of an electrical test of the insulation and the measurement signal (11) of a surface test of the insulation are combined with one another by means of a logic circuit (8) in such a manner that when both measurement signals are present, an additional output signal (14) is generated. This output signal is suitably generated in dependence on the length in time of the measurement signal (11) of the surface test. <IMAGE>

Abstract: PCT No. PCT/EP90/00067 Sec. 371 Date Jul. 22, 1991 Sec. 102(e) Date Jul. 22, 1991 PCT Filed Jan. 12, 1990 PCT Pub. No. WO90/08276 PCT Pub. Date Jul. 26, 1990.A gate valve has a one-piece casing which contains a valve chamber. The casing is provided with a tubular stub on either side of the chamber, and the stubs serve to connect the valve to a pair of pipes. The chamber has a non-circular sealing surface which is inclined to the direction of flow. A valving element having a non-circular sealing surface complementary to the sealing surface of the chamber is insertable in the latter via a selected one of the stubs. Following insertion, the valving element is connected to a spindle. Both the valving element and the spindle are held against rotation, and movement of the valving element towards and away from the sealing surface of the chamber is achieved by a rotary nut which is threaded onto the spindle. The sealing surface of the valving element delimits a region having a maximum dimension greater than the maximum dimension of the selected stub as considered in planes normal to the flow direction.

Title: Device for suppressing line-conducted noise signals in an electronic module
Inventor: TOUSSAINT HANS-NORBERT DR ING
IPC: H04B15/00
Filed: 1989-03-15
Abstract: An electronic filter circuit is intended to be produced by means of which noise signals can be filtered out in an electronic module, the length of the feeder lines to the filter circuit being intended to be as short as possible and reproducible. Conductor surfaces (6, 9) and wound conductor paths (8) are incorporated in a motherboard comprising a plurality of mutually insulated conducting layers, by means of which capacitors and inductive resistors are implemented in two-dimensional fashion on the motherboard. The capacitors and inductive resistors are interconnected by means of conductor paths to form a filter circuit. The motherboard (1) has bores (5) to feed through the terminal pins (10, 11, 12, 13, 14, 15) of the electronic module. Some of the terminal pins of the electronic module are conductively connected to the motherboard by soldering. The terminal pins of the electronic module protruding through the bores of the motherboard are soldered to the base board. The two-dimensional design of the filter circuit enables space-saving accommodation on an electronic module and can also enable the retrofitting of electronic modules with filter components. <IMAGE>

Title: Clocked very large scale CMOS digital circuit - uses delay circuits to generate varying delayed clock pulses to drive sub-circuits, thus reducing switching current surges
Inventor: KOVACS-BIRKAS ATTILA DIPL ING
IPC: G11C7/02
Filed: 1989-04-12
Abstract: The CMOS digital circuit, is used in pipelining techniques for increasing data flow rate.

Title: Vehicular friction clutch actuator dependent on speed difference - includes controller for linear redn. of desired value of difference between engine and prim. gear speeds
Inventor: NAGLER FRANZ DIPL ING
IPC: G05B7/02
Filed: 1989-10-25
