Abstract: A high speed low Capacitance Complementary Logic Input Parallel (CLIP) logic family includes an FET driving stage, a complementary FET inverter, and at least one gating FET. The dimensions of the gating FET are controlled relative to the dimensions of the driving stage FETs to provide a high speed logic circuit. AND and OR CLIP logic circuits may be provided. A clocked CLIP logic circuit may be provided by adding a clocking FET. A latching clocked CLIP logic circuit may also be provided by adding a latching FET. In the latching clocked CLIP logic circuit, the gate output is latched so that it does not change during the clock period regardless of changes in the logic inputs of the circuit. The speed of the CLIP logic circuits may be further increased by including germanium in the channel of its P-channel FETs to thereby increase carrier mobility in the P-channel FETs. The N-channel FETs are free of germanium. The internal capacitance of the CLIP logic circuits is also decreased by using common diffusion regions in the integrated circuit for pairs of driving stage FETs. Common source and/or common drain diffusion regions may be used.

Abstract: An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac contains 35-75 % by weight of novolac, less than 25 % by weight of water, and 10-40 % by weight of an aliphatic divalent, trivalent or tetravalent alcohol. The adhesive composition may also contain up to 20 % by weight of filler, based on the amount of novolac, water and alcohol. In a method for preparing the adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac, the novolac is produced by conventional condensation, whereupon an aliphatic divalent, trivalent or tetravalent alcohol is added and water in the novolac is distilled off, resulting in an adhesive composition as defined above. Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalent or tetravalent alcohol.

A device for applying the method in a cable winding machine comprises detecting devices supposed by the guide for detecting each reel flange and for changing the angle of lag of the cable to its parallel position before reversing devices detect the reel flange and reverse the direction of displacement of the guide with respect to the reel.

Abstract: Large scale integrated circuits are fabricated using redundant circuit elements to replace defective circuit elements by discretionary interconnect changes as determined by fine-grain testing of the integrated circuits after the logic units (such as individual transistors or logic gates) are fabricated and before they are electrically interconnected. The redundant circuit elements are then interconnected to non-defective circuit elements by one of two methods. In the first method a stepper-scanner apparatus modified to expose most of a resist layer defines the interconnect circuitry, but is shuttered-off over the discretionary interconnect changes. Then the discretionary interconnect changes are exposed by a conventional direct write on wafer pattern generation apparatus. In the second method, the interconnect patterning is accomplished by first fabricating a fixed custom mask defining the interconnect layer for a particular lot size (such as 100) of wafers. The fixed mask is fabricated after each wafer of the lot has been tested, and incorporates all the discretionary changes required to avoid interconnection to each defective circuit element in each of the wafers. The fixed custom mask is then used to expose the resist layer defining the interconnect circuitry for each of the 100 wafers. <IMAGE>

Abstract: A packet communications system provides for point-to-point packet routing and broadcast packet routing to limited subsets of nodes in the network, using a routing field in the packet header which is processed according to two different protocols. A third protocol is provided in which a packet can be broadcast to the limited subset even when launched from a node which is not a member of the subset. The routing field includes a first portion which contains the route labels necessary to deliver the packet to the broadcast subset. A second portion of the routing field contains the broadcast subset identifier which can then be used to deliver the packet to all of the members of the broadcast subset. Provision is made to backtrack deliver the packet to the last node identified before the broadcast subset if that last node is itself a member of the subset. <IMAGE>

Abstract: A method of improving the performance of a pollutant abatement means, e.g., catalytic converter (16), used to purify engine exhaust gas streams and the like includes combusting a combustion mixture of air and a low ignition temperature fuel in the exhaust gas stream upstream of the catalytic converter (16) to oxidize carbon monoxide and unburned hydrocarbons, and/or to rapidly heat the catalytic converter to its operating temperature. Reaction conditions are maintained so as to cause the combustion mixture to ignite spontaneously. A control system may be used to regulate the supply of the combustion mixture in response to time lapse or temperature of the catalyst or both. The apparatus includes a fuel supply (18) and a fuel line (20) controlled by a valve (22) to deliver a low ignition temperature fuel into the exhaust gas discharge line (14) associated with the engine (12). An air pump (26) provides combustion air through an air line (28) into the exhaust gas discharge line (14). Optionally, a thermocouple (36) attached to the catalytic converter (16) signals a controller (38) to reduce or stop the flow of air and/or low ignition temperature fuel in response to the temperature of the catalytic converter (16).
