A method for acquiring an image or spectrum of a subject or object residing within the magnetic field of a magnetic resonance apparatus, comprises the steps of:

• • executing a predetermined pulse sequence for applying gradient magnetic fields and for coupling in electromagnetic excitation pulses to induce nuclear magnetic resonance within the subject or object;
  • detecting an electromagnetic signal resulting from said magnetic resonance; and
  • constructing at least one image or magnetic resonance spectrum of said subject or object from said detected electromagnetic signal.

According to the invention, said coupling in of the electromagnetic excitation pulse and/or said detecting of the electromagnetic signal are carried out substantially by means of travelling electromagnetic waves.

An improved seasoning system 10, 11, 13 uniformly coats a food product with the desired amount of seasoning, with the seasoning rate preferably being controlled as a function of the product volume signals from the sensors 26, 34, 108 and 110. The seasoning system preferably utilizes linear motion conveyors and either a rotating drum 36 or a deflector 98 and a second seasoning unit 112, 114 between linear conveyors 94, 96. Oil may be sprayed onto food products and tumbled in a drum 16 which both rotates and moves in a reciprocating manner with the conveyor tray 14. An improved seasoning tray 123, 144, 148 has a planar floor 122, 138, 162 with an angled discharge edge 124, 137, 182 for uniformly distributing seasoning on the product. The seasoning system minimizes damage to the food product and uniformly coats the product with a desired amount of seasoning.

A method of manufacture for optical spectral filters with omnidirectional properties in the visible, near IR, mid IR and/or far IR (infrared) spectral ranges is based on the formation of large arrays of coherently modulated waveguides by electrochemical etching of a semiconductor wafer to form a pore array. Further processing of said porous semiconductor wafer optimizes the filtering properties of such a material. The method of filter manufacturing is large scale compatible and economically favorable. The resulting exemplary non-limiting illustrative filters are stable, do not degrade over time, do not exhibit material delamination problems and offer superior transmittance for use as bandpass, band blocking and narrow-bandpass filters. Such filters are useful for a wide variety of applications including but not limited to spectroscopy, optical communications, astronomy and sensing.

The present invention provides an underwater wireless communications hotspot comprising an active zone which is circumscribed by a large closed loop antenna and within which wireless communication by means of electromagnetic signals can take place. The wireless communications hotspot of the present invention is suitable for data transfer between a communications node of the wireless hotspot and a receiver mounted on a mobile unit which is located inside the active zone of the hotspot. The wireless hotspot of the present invention provides a means for high bit rate data transfer from the communications node and the mobile unit, due to improved uniformity of coverage within the active zone of the hotspot and due to a reduction in the attenuation with distance compared to communications at positions outside the perimeter of a loop antenna.

An ALD method is described for depositing a composite layer comprised of three to five elements including one or two metals, Si, B and N. A metal containing gas is injected into a process chamber and purged followed by a N source gas and a purge and/or a Si or B source gas and a purge to complete a cycle and form a monolayer. A predetermined number of monolayers each having two or three elements is deposited to provide a composite film with good step coverage and a well controlled composition. The resulting layer is especially useful as a diffusion barrier layer for copper. Alternatively, a three component layer comprised of Hf, Zr, and O may be deposited and serves as a gate dielectric layer in a MOSFET device. The invention is also a thin film comprised of a plurality of monolayers each having two or three elements.

Center cores are formed by extrusion-molding ABS resin. Seven pieces of the center cores, which are juxtaposed to each other in the horizontal direction, are supplied by a pultruder, and reinforcing long-fibers impregnated with an unsaturated polyester resin are allowed to pass through dispersion guides and squeezing nozzles, to thus squeezing-mold a fiber-reinforced composite hollow structure having FRP made legs. A final squeezing nozzle is disposed in a cross head die through a cooling jacket, and the hollow structure thus molded is allowed to pass therethrough to be covered with the ABS resin in a state in which the outer periphery of the hollow structure is heated. The hollow structure thus covered is subjected to cooled-sizing through a plurality of horizontal and vertical pairs of rollers, and then cured in a hot curing tank. The surface covered with the ABS resin is subjected to a surface-treatment of imparting irregularities for giving an antislipping function to the surface. A thermoplastic resin-made protective cap is fitted to an end of the center core. The apparatus for manufacturing a composite hollow structure has a plurality of pairs of rotatable and heat-resisting sizing rollers. The plurality of pairs of the sizing rollers are disposed in the pultruding direction while being gradually cooled in the order from those positioned on the upstream side to those positioned on the downstream side for sizing the softened outer layer covering the outer periphery of the intermediate layer.
