An apparatus and method for electrospinning polymer fibers and membranes. The method includes electrospinning a polymer fiber from a conducting fluid in the presence of a first electric field established between a conducting fluid introduction device and a ground source and modifying the first electric field with a second electric field to form a jet stream of the conducting fluid. The method also includes electrically controlling the flow characteristics of the jet stream, forming a plurality of electrospinning jet streams and independently controlling the flow characteristics of at least one of the jet streams. The apparatus for electrospinning includes a conducting fluid introduction device containing a plurality of electrospinning spinnerets, a ground member positioned adjacent to the spinnerets, a support member disposed between the spinnerets and the ground member and movable to receive fibers formed from the conducting fluid, and a component for controlling the flow characteristics of conducting fluid from at least one spinneret independently from another spinneret.

A gaming system produces a multiple-play physical pull tab ticket at the request of a player. Each chance in the game is associated with a game play record which has been produced and stored in the system prior to the sale of the physical game ticket. A player in the game selects a number of game play outcomes or plays to be purchased and the gaming system responds to the request by producing and distributing to the player a pull tab ticket having the requested number of game play outcomes printed or otherwise formed on a ticket substrate. Game play information specifying the outcomes of each game play printed on the game ticket may be printed or otherwise encoded on the game ticket. A player terminal may read this game play information using a suitable scanning device and may then display the results of the plays to the player.

This invention relates generally to the field of Magnetic Resonance Imaging (MRI) systems for generating diagnostic images of a patient's internal organs and more particularly, this invention relates to improved MRI systems with decreased interference between the magnetic field used for producing diagnostic images and the magnetic fields generated by the electric motors used for driving the pistons of the contrast media injectors. Additionally, the system employs an improved communication link between an externally located system controller and the injection head control unit located within the electromagnetic isolation barrier which defines the magnetic imaging room.

An electric device having a plurality of nanowires, in which at least one of the nanowires is cut or changed in its electric characteristics so as to have a desired characteristic value of the electric device.

It has been difficult to manufacture an inside surface progressive-power lens which is as thin as an outside surface progressive-power lens due to a limited configuration of an object-side refractive surface of the inside surface progressive-power lens. However, a thin progressive-power lens with less blur and distortion can be provided at a reduced cost by forming its object-side refractive surface from an aspherical surface which is symmetric with respect to a rotational axis and has a smaller curvature at a distance reference point than that at a near reference point, and by forming an eyeball-side refractive surface from a combination of a progressive surface, an astigmatic refraction surface and an “as-worn” corrective aspherical surface.

A terminal crimping structure onto aluminum electric-wire, for crimping a terminal onto an aluminum electric-wire including: an electrical conductor part comprising numerous strands; and a coating part coated on the . electrical conductor part; wherein the terminal has a wire barrel to be crimped onto the electrical conductor part of the aluminum electric-wire; and wherein the compressed ratio of the aluminum electric-wire's conductor part by the wire barrel is within a range of 50 to 70%, in terms of the ratio of (cross-sectional area of aluminum electric-wire's conductor part at crimped portion) / (cross-sectional area of aluminum electric-wire's conductor part before crimping).

In a process for producing a biocompatible stent, a tubular substrate of the stent adapted for diametric expansion has a layer of a noble metal oxide formed over at least the outer surface of greater diameter of the substrate, the substrate being composed of a metal or an alloy thereof that is non-noble or less-noble than the layer's noble metal. An interface region adapted to prevent corrosion and to provide a firm bond between the surface of the substrate and the noble metal oxide layer is established, at least in part, by forming the noble metal oxide layer with a progressively varying concentration of noble metal-to-oxide with depth of the layer such that a surface of pure noble metal and negligible oxide of the layer is in closest proximity to the surface of the substrate. In one embodiment of the process, the interface region is established by forming the surface of pure noble metal and negligible oxide thereof in direct contact with the metal or alloy of the substrate surface. In another, the interface region is established by first creating an oxide of the substrate metal or alloy thereof at the substrate surface, and then forming the noble metal oxide layer as above, but in contact with the substrate metal or alloy oxide. Alternatively, the noble metal oxide layer has no progressively varying concentration but simply overlies an oxide of the substrate metal or alloy.

A sound input device includes a differential microphone, configured to receive sound including noise, and generate a first signal in accordance with the sound; a detector, configured to detect the noise, and generate a second signal in accordance with the detected noise; and a controller, configured to control at least one of suppression of high-frequency components of the first signal and changing of a frequency band to be suppressed of the first signal based on the second signal.

A bimetallic thin plate jointing element that is jointed, such that a good electric characteristics are maintained, is provided. Thin plate jointing element (10) is formed by welding and jointing positive-electrode terminal (1) and negative-electrode terminal (2) having different melting points, and having flexibility. A plurality of spot-like welding areas (3) formed, for example, by laser welding are provided at overlaid portion (9) of positive-electrode terminal (1) and negative-electrode terminal (2). Welding areas (3) are formed by irradiating laser beams from the side of positive-electrode terminal (1) having a relatively low melting point, and have a cross sectional shape that is tapered from the side of positive-electrode terminal (1) side toward negative-electrode terminal (2).

In a method for manufacturing a glass sealed body, a paste including powdered glass and a binder is discharged from an outlet whose shape is a closed curve to fowl a partition whose shape is a closed curve over a first glass substrate; the partition is heated so that the binder is volatilized and the powdered glass is fused to be a frit glass; and the frit glass and a second glass substrate are heated while disposing in close contact with each other, so that the frit glass and the second glass substrate are welded together to form a closed space by the frit glass, the first glass substrate, and the second glass substrate. A light-emitting element is sealed with the glass sealed body, so that the sealing is hardly broken even when impact or external force is applied.

In an antenna apparatus, on an undersurface of a metal cover, a feeding coil module is disposed. In a casing, a printed circuit board is included. A ground conductor, a feeding pin, and a ground connection conductor are disposed on the printed circuit board. When the metal cover is mounted on the casing, the feeding pin is in contact with a connection portion of the feeding coil module and is electrically connected thereto. The ground connection conductor is in contact with the metal cover and connects the metal cover to the ground conductor. The ground connection conductor is disposed at either side of a slit outside an area in which the current density of an induced current flowing through the metal cover is in a range from a maximum value to approximately 80% of the maximum value or one side of the slit in the area.
