A by-pass fluid flow amplifier which contains a primary nozzle and a primary profile for discharging compressed air into a conduit of the air amplifier and entraining ambient air in the process. A secondary nozzle and a secondary profile for discharging compressed air into the conduit of the air amplifier towards the rear that assists the primary nozzle such as to allow consistent fluid wall attachment of the compressed air and the entrained air caused by the primary nozzle and the primary profile. The secondary nozzle increases the total flow of the amplifier and prohibits the total flow from traveling towards the center of the conduit where flow reversal and turbulence are likely to occur.

A small magnet assembly is scanned in a retrograde planetary or epicyclic path about the back of a target being plasma sputtered including an orbital rotation about the center axis of the target and a planetary rotation about another axis rotating about the target center axis. The magnet assembly passes through the target center, thus allowing full target coverage. A properly chosen ratio of the two rotations about respective axes produces a much slower magnet velocity near the target periphery than at the target center. A geared planetary mechanism includes a rotating drive plate, a fixed center gear, and an idler and a follower gear rotatably supported in the drive plane supporting a cantilevered magnet assembly on the side of the drive plate facing the target. A belted planetary mechanism includes a fixed center capstan, a follower pulley supporting the magnet assembly, and a belt wrapped around them.

A fin for a heat exchanger coil assembly and a method of manufacturing the fin is provided. The fin includes a heat transfer enhancement pattern which appears sinusoidal in shape. The base wavy pattern of the enhancement pattern includes two wavelengths within each tube row and includes seven discrete segments. Six of the seven segments are circular arc segments. The seventh segment comprises two linear segments which form a condensate channel. The segments are arranged in a particular order at specific distances offset (above and below) from a leading edge nominal air streamline (LENAS) by a fraction of a nominal fin pitch Pf. The LENAS is related to the “normal” base wavy pattern used in other fins.

A resonant actuator includes a driving unit having a displacement element that vibrates at a resonance frequency or in a frequency range in the vicinity of a resonance frequency and having a driven member that is driven by the displacement element, in which the displacement element has a piezoelectric ceramic body made of a bismuth layered compound. The displacement direction of the displacement element is preferably substantially the same as the direction of polarization of the piezoelectric ceramic body. The bismuth layered compound is preferably oriented such that the direction of the c crystallographic axis is substantially perpendicular to the direction of polarization of the piezoelectric ceramic body. More preferably, the degree of c-axis orientation is determined to be at least about 75% by the Lotgering method. Thereby, it is possible to provide a resonant actuator having a large saturated vibration velocity, minimizing reductions in the resonance frequency fr and the mechanical quality factor Qm without the destabilization of the vibration velocity even at a high vibration velocity, and having a large amount of displacement even at a high electric field.

An exhaust gas recirculation system for an internal combustion engine by which a portion of exhaust gas from the engine is recirculated from an exhaust line of the engine into an intake line of the engine, introducing the exhaust gas flow into the intake port around the intake valve seat region. The present invention provides a unique means of introducing EGR / Crankcase gas into the combustion chamber of an engine. The location for introducing EGR / Crankacse gas is above the intake valve seat region. The system does not require any pumping arrangement either through the use of external pumps or by raising the exhaust back presssure in the system. This system does not penalize airflow into the system as the flow passage does not require reduction in size to the air passage. Introducing the EGR just during the air induction process means the quantity of exhaust gas in the system is minimal. This results in improved transient response. Use of minimal EGR also results in smaller EGR cooling system. The introduction of crankcase into the combustion chamber results in lowering of the particulates in the exhuast. The oil particles in the crankcase gas also improves intake valve life.

Centers of gravity of the left and right footboards are located between the left and right rear wheels.

When a satellite is orbiting the earth in an elliptic orbit, it has a certain inclination with respect to the earth's equator. The usual way to change the inclination is perform a maneuver by firing the rocket engines at the periapsis of the ellipse. This then forces the satellite into the desired inclination. There is a substantially more fuel efficient way to change the inclination. This is done by an indirect route by first doing a maneuver to bring the satellite to the moon on a BCT (Ballistic Capture Transfer). At the moon, the satellite is in the so called fuzzy boundary or weak stability boundary. A negligibly small maneuver can then bring it back to the earth on a reverse BCT to the desired earth inclination. Another maneuver puts it into the new ellipse at the earth. In the case of satellites launched from Vandenberg AFB into LEO in a circular orbit of an altitude of 700 km with an inclination of 34°, approximately 6 km / s is required to change the inclination to 90°. This yields a savings of approximately 13% in Delta-V as compared to the standard approach which could translate into a significant increase of payload or perhaps a smaller launch vehicle. This may have applications to commercial satellite launches for the Iridium or Teledesic networks and others.
