A method and apparatus for facilitating efficient database searching for records referenced by a data reference, the method including examining a data reference and related information to identify markup language codes or tags associated with the data reference and, based the markup language codes or tags, selecting a sub-set of databases to be searched for data referenced records and rendering identified records accessible.

The device includes a pair of flat planar vanes securely mounted within a cylindrical housing. The vanes have a medial slit extending from the center to a longitudinal end of the vane. The vanes are interconnected at the slits so that they are in criss-cross positioning. The vanes are axially angled so that when positioned in an intake air duct the vanes impart a swirling motion to the air entering the engine providing more complete mixing of the air and fuel and when positioned in an exhaust passageway the vanes impart a swirling motion to the exhaust gases exiting the engine providing scavenging of the exhaust gases.

A plasma generating apparatus has a plasma-generating vessel into which a gas is introduced. A coaxial line is inserted into the plasma-generating vessel. The coaxial line is insulated from the vessel with an insulator. The coaxial line has a central conductor and an outer conductor, to both of which microwave is supplied from a magnetron. That part of the central conductor which is located inside the plasma-generating vessel has, disposed therein, permanent magnets which form a cusp field. A seed plasma is formed around the permanent magnets by microwave discharge. A direct-current voltage is applied from a direct-voltage source between the outer conductor 24 and the plasma-generating vessel. Upon this application, electrons in the seed plasma move toward the inner wall of the plasma-generating vessel and are accelerated to ionize the gas. The ionized gas serves as seeds to cause arc discharge between the outer conductor and the plasma-generating vessel to generate a main plasma. By disposing an extracting electrode at the opening of the plasma-generating vessel, ion beams can be extracted from the main plasma.

A hybrid disc whose recordable-band grooves are wider and shallower than the pre-recorded ROM data pits. The ROM pits may be pre-recorded in ROM grooves that are at least as wide, but shallower than, the ROM pits. The ROM lands intervene between consecutive ROM pits, whether or not a ROM groove is provided. In the preferred embodiment, one beam of a dual beam apparatus records the ROM pits, while the other beam records the pre-grooves, and also records the ROM groove, if present. In most embodiments a thermal mastering process provides smooth feature surfaces to facilitate replication of the hybrid disc masters. The berms normally forming at the radial extremities of the pits and grooves in the masters, by thermal expulsion processes, may be reduced or eliminated by methods taught.

A multi-chip light emitting device (LED) uses a low-cost carrier structure that facilitates the use of substrates that are optimized to support the devices that require a substrate. Depending upon the type of LED elements used, some of the LED elements may be mounted on the carrier structure, rather than on the more expensive ceramic substrate. In like manner, other devices, such as sensors and control elements, may be mounted on the carrier structure as well. Because the carrier and substrate structures are formed independent of the encapsulation and other after-formation processes, these structures can be tested prior to encapsulation, thereby avoiding the cost of these processes being applied to inoperative structures.

A muffler for an internal combustion engine has a casing forming an expansion chamber therein. An inlet duct is connected to the casing and projects into the expansion chamber and discharges exhaust fluid into the expansion chamber. The casing tapers in an upstream direction to form a pocket for receiving reverse flow of the exhaust gases and to minimize reverse flow from flowing back into the inlet duct in an upstream direction. In the discharge end of the inlet duct are a set of primary vanes and a set of secondary vanes. The vanes are secured to the walls of the duct and extend radially toward the central area of the duct. The vanes are angled in order to deflect the exhaust fluid flow into a swirling movement as it is discharged into the expansion chamber and maintains that swirling movement while passing out of the casing through the outlet duct.
