Methods for forming calibration standards for an inspection system and calibration standards are provided. One method includes scanning a first and a second specimen with an optical system. Master standard particles having a lateral dimension traceable to a national or international authority or first principles measurements are deposited on the first specimen. Product standard particles are deposited on the second specimen. In addition, the method includes determining a lateral dimension of the product standard particles by comparing data generated by scanning the two specimens. One calibration standard includes particles having a lateral dimension of less than about 100 nm deposited on a specimen. A distribution of the lateral dimension has a full width at half maximum of less than about 3%. The uncertainty of the lateral dimension is less than about 2%. Therefore, the standard meets the requirements for the 130 nm technology generation of semiconductor devices.

Various embodiments relate to a dose unit for a dry powder inhaler including: a dose carrier including a plurality of pockets each adapted to contain a dose of medication powder suitable for inhalation, the pockets being sequentially arranged such that the content of the pockets can be sequentially exposed to a flow of air for successive inhalations and a plurality of medication powder doses arranged in the pockets of the dose carrier. The doses are regularly distributed in the pockets according to a sequence of identical groups, each group including at least one blank pocket and one pocket containing a dose of medication powder. Various embodiments also relate to a pack including one such dose unit and one further dose unit with all pockets containing a medication powder. Various embodiments further relate to a dry powder inhaler including such a pack of dose units.

The exemplary embodiments relate to a multilayer aluminum alloy sheet material suitable for fabrication into coolant-conveying tubes, headers and the like used for heat exchangers, and to the tubes and headers, etc., fabricated from the sheet. The multi-layer metal sheet has a core layer of aluminum alloy having first and second sides. The first side has an interlayer made of a Zn-containing aluminum alloy positioned between a Zn-containing outer layer and the core layer. The alloy of the outer layer is more electronegative than the alloy of the interlayer. The alloy of the interlayer is preferably more electronegative than the alloy of the core layer. The first side clad in this way is the side intended for exposure to the coolant, and provides good resistance to corrosion and erosion.

Disclosed is a method of determining an overlay error between two layers of a multiple layer sample. For a plurality of periodic targets that each have a first structure formed from a first layer and a second structure formed from a second layer of the sample, an interferometer is employed to modulate substantially a plurality of wavelengths of a broadband source and then acquiring one or more images of the periodic targets. There are predefined offsets between the first and second structures. An overlay error between the first and second structures is then determined by analyzing the one or more acquired images from the periodic targets using a scatterometry overlay technique based on the predefined offsets.

Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.
摘要:
Constant pressure internal combustion engine having an elongated combustion chamber which in some embodiments is folded back upon itself and has a rough, twisting interior side wall, a fuel inlet for introducing fuel into the chamber, a compression chamber in communication with the combustion chamber, means for varying the volume of the compression chamber and combustion chamber to form a mixture of fuel and air that burns as it travels through the chamber and is further mixed by the rough, twisting side wall of the chamber, an expansion chamber in communication with the combustion chamber, and an output member in the expansion chamber which is driven by pressure produced by the burning mixture, with the means for varying the volume of the compression chamber and the output member in the expansion chamber being connected together for movement in concert such that the pressure remains substantially constant within the combustion chamber. A gas flow separator near the fuel inlet forms one or more smaller volumes within the combustion chamber where the fuel can mix and burn with only a portion of the air introduced into the chamber. Long, sharp protrusions extend inwardly from the wall of the combustion chamber and form hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber, and these protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air.
