摘要:
The use as a sludge controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for maintaining oil pathways and/or lubrication in an engine.
摘要:
The use as a piston varnish controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for controlling power output, fuel economy, engine wear, piston ring sticking and blow-by.
摘要:
Projection optics for a lithographic projection system is provided that comprises a spatial light modulator (SLM) from which radiation is reflected and directed to a projection lens that projects the radiation to a substrate. The SLM is illuminated by non telecentric off axis illumination (e.g. from laser radiation that has a spectral bandwidth of the order of 1 picometer, and the projection optics is configured for significant reduction (e.g. at least 10× reduction, 20× reduction, or 50× reduction).
摘要:
New and useful optical components are provided, for use in measuring projection lens characteristics of an optical imaging system that images a substrate. The optical components comprise an array of full NA imagers located at the substrate plane, and a relay system for imaging the imagers to a detector that is remote from the substrate.
摘要:
An optical assembly for a system for inspecting or measuring of an object is provided that is configured to move as a unit with a system, as the system is pointed at a target, and eliminates the need for a large scanning (pointing) mirror that is moveable relative to other parts of the system. The optical assembly comprises catadioptric optics configured to fold the optical path of the pointing beam and measurement beam that are being directed through the outlet of the system, to compress the size of the optical assembly.

摘要:
The use as an intake valve deposit clean-up additive in a fuel composition for a port fuel injection spark-ignition internal combustion engine or a fuel injector deposit clean-up additive in a fuel composition for a direct injection spark-ignition internal combustion engine of a combination of: a. at least one hydrocarbyl-substituted aromatic compound; and b. at least one polyalkylene amine.
