Abstract: A master slice type integrated circuit in which various circuits may be formed by varying the routing of inter­connections, comprising a plurality of input/output cells (23) being arranged in a peripheral region on a semiconductor chip (20), a plurality of basic cell columns (22) each comprising a plurality of basic cells (21) arranged in a predetermined direction (A), each basic cell (21) con­stituting transistors, and an interconnection region (25) formed on the chip (20), for accommodating a data bus (55). The master slice type integrated circuit further comprises a plurality of latch cells (26) arranged in the basic cell columns (22), for keeping a potential of a data bus (55) laid on the interconnection region to prevent the data bus (55) from being changed into a floating state. Each latch cell (26) comprises transistors, each of which has a driving capability smaller than that of each transistor of the basic cell (21).

Abstract: It now has been found that uncured rubber composition comprising rubbers having an unsaturated carbon chain and at least one carbon black can be improved by including therein, a minor property-improv­ing amount of at least one aromatic heterocyclic di-N­oxide compound of the partial formula
      wherein the depicted carbon atoms are part of an option­ally substituted aromatic ring, and R¹ and R² are each independently hydrogen, hydrocarbyl, halohydrocar­byl, hydrocarbyloxy, hydrocarbyl sulfonyl, hydrocarbyl thio, hydrocarbylsulfoxidyl, halogen, amino,

-C(O)NHN(R³)₂ 
 
wherein each R³ is independently hydrogen or a hydro­carbyl group, R⁴ is a divalent hydrocarbyl group, R⁶ is hydrogen, hydrocarbyl, -R⁴OR³, or -R⁴COOR³; R⁷ is hydrogen or a hydrocarbyl group; R⁸ is hydro­gen or a hydrocarbyl, an amino, or a hydroxyl group; R⁷ and R⁸ may be hydrocarbyl groups joined together to form a ring including the nitrogen atom, and Y is O, divalent S, -NH-, -S(O)- or -S(O)₂ or R¹ and R² may be joined together to form further ring systems which may be saturated or unsaturated, and further substituted or unsubstituted. When vulcanizates are prepared from such uncured rubber compositions, parti­cularly when the carbon black used therein has an average surface area of at least about 20 m²/g, the vulcanizates exhibit reduced low strain hysteresis and exhibit no significant undesirable odor. 
     In another aspect of the invention, a filled vulcanizate made by vulcanizing uncured compositions of the type described above and containing a filler, particularly carbon black, is improved in filler interaction, hysteresis, modulus, compression set and resiliency. Rubber articles and portions thereof made from such vulcanizates such as tires, hoses, belts, springs, treads, sidewalls and the like can be made utilizing the improved filled vulcanizates of the invention.

Abstract: In a conventional optical heterodyne receiver with a standard six- port fibre coupler, a loss of sensitivity occurs compared with an optical heterodyne receiver with a 90 DEG  hybrid and, furthermore, laser amplitude noise is inadequately suppressed. Therefore, according to the invention, the receiver with a six-port fibre coupler (K) is designed as a pair of balanced receivers, so that the photocurrent amplifiers connected behind the photodiodes (PD1, PD2, PD3), through suppression of the DC components in the photocurrent, receive only the differences in current between the photocurrents of in each case two photodiodes. <IMAGE>

Abstract: The threaded connection between a graphite shaft (1) and a metal shaft (2), such as is used to drive a rotating nozzle in the refining of aluminum, is strengthened by coating the graphite surface that contact the flange portion (7) of the metal shaft (2) prior to the fastening of said shafts together. The coating (10) comprises solid material bonded to the graphite surface (8) to form a hard, adherent coating, deposited by coating said graphite surface (8) with a solution or colloidal dispersion of said material and drying said solution or colloidal dispersion to leave said solid material bonded to the graphite surface. The coating of said graphite shaft serves to greatly strengthen the threaded connection and the ability of said connection to transmit driving torque (5) from the metal shaft to the graphite shaft.

Abstract: Line trunk groups connected to the central switching network via time-division-multiplex lines and exhibiting, among other things, one distributed switching network each and one group controller each, are associated with one another in pairs. Line units which are individually associated with one or the other of two line trunk groups are connected to the distributed switching network of their own line trunk group in each case in normal operation and can be switched to the distributed switching network of the other line trunk group in each case in stand-by mode. In the line units, compensation memories are doubly provided, in each case for the message stream to and from the distributed switching network belonging to the line trunk group, on the one hand, and for the message stream to and from the distributed switching network of the respective partner line trunk group. The compensation memories receive for their clock-controlled output events the pulse clock in each case from the distributed switching network towards which they emit their messages. First compensation memories receive their pulse clock from their own line trunk group; second compensation memories receive their pulse clock from the respective partner line trunk group. …<IMAGE>…

Abstract: In light-liquid separators of upright cylindrical construction, a markedly improved degree of separation is achieved when the waste water to be cleaned flows through the separator (1) in a circular flow, that first ascends at the container edge and then descends in the interior. This flow pattern is achieved by means of a tangentially upwardly directed inlet (4) in the lower half of the separator and a central base outlet (5). The centre of the separator can accommodate the conventional floating stopcock (9), which closes the outlet when the container maximum is reached. This floating stopcock is advantageously surrounded by a perforated guide cage (10). The guide cage can act as a carrier for a hollow cylindrical coalescence element (11), for retaining very fine droplets of light liquids. <IMAGE>

Abstract: Un système de réglage (14) de la quantité de carburant amenée à un moteur à combustion comprend une première unité de réglage (10.1.1) et une deuxième unité de réglage (10.2.1). La première unité de réglage fournit en fonction de signaux qu'elle reçoit d'un premier agencement détecteur (11.1) une première valeur de réglage à la pompe d'injection de carburant (12.1). La deuxième unité de réglage détermine en fonction des signaux d'un deuxième agencement détecteur (11.2) une deuxième valeur de réglage qui conviendrait elle aussi à commander la pompe d'injection mais qui est utilisé pour calibrer la première unité de réglage. On met en oeuvre un système de réglage ainsi construit lorsque le deuxième agencement détecteur utilisé est plus lent mais plus précis que le premier agencement détecteur. La deuxième valeur de réglage correspond alors mieux que la première valeur de réglage à une valeur requise pour obtenir une valeur lambda voulue. Par contre, la première valeur de réglage réagit plus rapidement à des changements de la masse d'air amenée au moteur à combustion. Etant donné que la première unité de commande est calibrée au moyen de la deuxième valeur de réglage, on peut influencer la première valeur de réglage avec davantage de précision que dans le passé, mais à une vitesse toujours aussi élevée.
