Reddish-brown to yellow shade colorants suitable for ribbon and ball point inks are produced from the glassy waste by-product of pararosaniline manufacture by slurrying the residue in mineral acid, diazotizing, and coupling. the resulting colorants are useful in preparing inks.
摘要:
The invention relates to a sulphide catalyst for electrochemical reduction of oxygen particularly stable in chemically aggressive environments such as chlorinated hydrochloric acid. The catalyst of the invention comprises a noble metal sulphide single crystalline phase supported on a conductive carbon essentially free of zerovalent metal and of metal oxide phases, obtainable by reduction of metal precursor salts and thio-precursors with a borohydride or other strong reducing agent.

A method, apparatus, and computer program product for visually indicating the interaction between one or more edges of a design that contribute to a defined critical area pattern.
摘要:
A method of and service for optimizing an integrated circuit design to improve manufacturing yield. The invention uses manufacturing data and algorithms to identify areas with high probability of failures, i.e. critical areas. The invention further changes the layout of the circuit design to reduce critical area thereby reducing the probability of a fault occurring during manufacturing. Methods of identifying critical area include common run, geometry mapping, and Voronoi diagrams. Optimization includes but is not limited to incremental movement and adjustment of shape dimensions until optimization objectives are achieved and critical area is reduced.

A method for providing redundancy in a daisy chain local area network employing Category 5 cabling for connecting network devices uses the normally unused twisted wire pairs in the single Cat 5 cable connecting adjacent network devices. The method includes forming in each network device a passive signal path connecting pins of an upstream port associated with the normally unused twisted wire pairs of the Cat 5 cable to pins of a downstream port associated with the normally unused twisted wire pairs of the Cat 5 cable, forming loop back connections at the terminal network devices where the loop back connections connect the normally used twisted wire pairs to the normally unused twisted wire pairs of the Cat 5 cable connected to the terminal network devices, and implementing a Spanning Tree Protocol in each of the network devices for defining an active signal path through the local area network.

Disclosed is a method that determines critical areas associated with different types of fault mechanisms in an integrated circuit design. The invention does this by constructing individual Voronoi diagrams for critical areas of individual fault mechanisms and a composite Voronoi diagram based on the individual Voronoi diagrams. The invention computes the critical area for composite fault mechanisms of the integrated circuit design based on the composite Voronoi diagram.
摘要:
An improved carbon supported-noble metal sulphide electrocatalyst suitable for being incorporated in gas-diffusion electrode structures, in particular in oxygen-reducing gas diffusion cathodes for aqueous hydrochloric acid electrolysis. The noble metal sulphide particles are monodispersed on the active carbon particles and the surface area ratio of noble metal sulphide particles to active carbon particles is at least 0.20.

The invention provides a method of modifying a hierarchical integrated circuit layout wherein the locations of hierarchical layout elements are represented with variables and formulae using these variables, which produces a formula-based hierarchical layout. These variables are constrained to be integers. The invention provides for a method for guiding the modification of the layout through an objective function defined on the same variables as the formula-based hierarchical layout. The invention simplifies the formula-based hierarchical layout by substituting constants for some of the variables, such that each of the formulae are reduced to expressions involving no more than two remaining variables. This produces a simplified layout equation and a simplified objective function. This also produces a partial solution to the hierarchical layout modification made up of the values selected for the constants.
