Title: Multilayer integrated circuit prepn. - using selective oxidn. of first metallic layer for masking in via hole prodn.
Inventor: KOKKOTAKIS NICHOLAS DR RER NAT
IPC: H01L21/768
Filed: 1976-09-21
Abstract: In the completion of multilayer circuitry of integrated semiconductor circuits, a layer of conductive metal is first applied over the insulating layer on a substrate and the windows left in it. Selective oxidation then creates the conductive track pattern by turning the rest into a metallic oxide layer. Via holes in an additional insulating layer are produced by plasma etching. The metallic oxide layer acts as etching mask for the production of the via holes. The conductor tracks in the first plane need not overlap the via holes in the second insulating layer and the smaller circuit dimensions result in a higher packing density per chip.

Title: Digital electronic three=phase electricity meter - has pulse-width and amplitude modulators connected to each phase
Inventor: STEINMUELLER GUENTER
IPC: G01R21/127
Filed: 1977-04-05
Abstract: The three-phase electricity meter consists of resistive shunts placed in each phase which detect the load currents. Each shunt is connected to an amplifier whose output voltage is proportional to the load current in the respective phase. This voltage controls pulse-width modulators. The modulators control switches via opto-electronic couplers. The switches are thus operated by digital signals from the modulators. Amplitude modulators, comprising inverting amplifiers connected to each phase, deliver a current proportional to the prduct of phase voltage and phase current. These currents are fed to a common current-frequency converter whose output controls a stepping motor driving a counter mechanism.

Patent DE-2741022-A1 (DE)
Inventor: CAGNIOUX SYLVAIN
IPC: H01H33/18
Filed: 1977-09-12
Abstract: This gas switch with self-blow-out of the arc has a quenching chamber (1) which is subdivided into a compression space (6) and a relief space (7). During the switching-off, a primary rotating arc (27) is produced between two ring electrodes (12, 18), which arc, under the action of a coil (11), through which the switching-off current flows, generates an overpressure of the filling gas in the compression space (6). As soon as the moving contact member (14) draws a secondary arc (28) between the auxiliary electrode (18) facing the relief space (7) and during this process releases a gas flow path to the relief space (7), the secondary arc (28) is quenched. The arc quenching can be improved by a second flow path if there is a further partition (30) by means of which an additional space (32) is produced, the latter being filled via openings (33) which can be closed by elastic flaps (34) in the first partition (5). The volume of the compression space (6) can also be adapted to large switching-off currents if the first partition (5) is made to be movable against a spring force. Due to the large second electrode (18), the compression ratio of the gases compressed in the compression space (6) under the action of the primary arc is increased and the switching-off capacity of the switch is improved even with weak switching currents. <IMAGE>
