    Abstract: PROBLEM TO BE SOLVED: To provide a field emission device utilizing the electron emission characteristics of a nano-conductor. SOLUTION: This field emission device deposits nano-conductors on a board 11 generally in the form of an aggregate 30 of wires or fibers, which do not have definite directions and a high aspect ratio in an entangled form. The aggregate 30 in the entangled form is exposed to an electric field vertically applied to the surface of a film during field emission. A loose nano-conductor end 10 in the structure tends to rise and align itself along a power line, so that the nano-conductor end 10 exposed to the electric field and aligned can be provided. Because of the indefinite and entangled nature of the aggregate 30, its density is adequately low and conforms to a criterion of d/h>0.1. In order to produce an aligned nanotube ends having an equal height, the emission characteristic is optimized by trimming the end parts as desired by the use of a high-temperature blade or spacer or by the use of a laser beam.

    Abstract: PROBLEM TO BE SOLVED: To easily assemble a nano-tube to a device by forming an adhesive carbon nano-tube film on a substrate. SOLUTION: In the manufacture of a flat panel display using a thin film nanotube electric field emitter, the display is provided with a cathode 41 having plural nano-tube emitters 47 and an anode 45 arranged separately from the emitters in vacuum sealing. A fluorescent layer 44 is provided on an anode conductor 49 formed on a transparent insulation substrate 46. A perforated electrically conductive gate layer 43 is provided between the cathode 41 and the anode 45 in the vicinity of the emitters 47 with an interval therebetween. When a space between the anode 45 and the cathode 41 is evacuated, and the voltage is applied, the electric field emitted electrons from the emitters 47 are accelerated by the electrically conductive gate layer 43, and moved toward the anode conductor 49. The electrons collide with the fluorescent layer 44 arranged between the emitters 47 and the anode 45 to generate the display image.

    Abstract: PROBLEM TO BE SOLVED: To provide a noise limiter conversion equipment and manufacturing method of the same having a saturation area to suppress an entering noise as well as a noise in a communication system and an internal noise. SOLUTION: This equipment has a conversion device 10 having a saturation area to suppress an entering noise and the other noise. The converter has a magnetic core 28, an input coil 32, and an output coil 34 formed, so that an output signal generated by magnetic coupling through the magnetic core between an output and output coil is based on an amplitude of the input signal. The magnetic core 28 has a saturation area 42 to suppress the output signal regardless of the amplitude of the input signal if the saturation area once reaches a saturation magnetization state. The saturation area 42 has a reduced saturation magnetization level caused by the area limited by the shape of the magnetic core 28 or the modified magnetically equivalent area having the same characteristic as the area limited by the shape.

    Abstract: A cathode (110) with an improved work function, for use in a lithographic system, such as the SCALPEL„¢ system, which includes a buffer (114) between a substrate (112) and an emissive layer (116), where the buffer alters, randomizes, miniaturizes, and/or isolates the grain structure at a surface of the substrate to reduce the grain size, randomize crystal orientation and reduce the rate of crystal growth. The buffer layer may be a solid solution or a multiphase alloy. A method of making the cathode by depositing a buffer between a surface of the substrate and an emissive layer, where the deposited buffer alters, randomizes, miniaturizes, and/or isolates the grain structure at a surface of the substrate to reduce the grain size, randomize crystal orientation and reduce the rate of crystal growth.

    Abstract: A method for fabricating adherent, patterned carbon nanotube films is provided. According to the invention, a substrate is patterned with a carbide-forming material, a carbon-dissolving material, or a low melting point metal. Carbon nanotubes are then deposited onto the patterned substrate, but have relatively poor adhesion to either the substrate material or the patterned material. The substrate is then annealed, typically in vacuum, at a temperature dependent on the particular patterning material, e.g., a temperature at which carbide formation occurs, at which carbon dissolution occurs, or at which the low melting point metal melts. The annealing thereby provides an adherent nanotube film over the patterned areas, while the nanotubes deposited onto the non-patterned areas are easily removed, e.g., by blowing, rubbing, brushing and/or ultrasonication in a solvent such as methanol.

    Abstract: An improved gridded microwave tube is provided, the tube containing a cold cathode, an anode, and a grid located between the anode and cathode. In one embodiment, the cold cathode has a refractory metal substrate and carbon nanotube emitters, the emitters having a diameter of 1 to 300 nm and a length of 0.05 to 100 .mu.m. The grid-cathode spacing is 1 to 100 .mu.m, the grid contains apertures having a maximum dimension of 0.5 to 100 .mu.m, and the grid thickness is 0.5 to 100 .mu.m. Emission from the cathode directly onto the grid material itself, which undesirably heats the grid, is reduced by either (a) the presence of a shadow mask between the grid and the emitters or (b) selective formation of the emitters in locations that correspond to the grid apertures. The microwave tube operates at a frequency of greater than 0.5 GHz, advantageously greater than 2 GHz.

    Abstract: Embodiments of the invention include a transformer device (10) having a saturation region for limiting ingress noise and other noise. The transformer comprises a magnetic core (28), an input coil (32) and an output coil (34) arranged so that the output signal caused by the magnetic linkage between the input and output coils through the magnetic core is based on the magnitude of the input signal. According to an embodiment of the invention, the magnetic core includes a saturation region (42) that limits the output signal regardless of the magnitude of the input signal once the saturation region reaches its saturation magnetization state. The saturation region comprises a reduced saturation magnetization level caused by a geometrically constricted region of the magnetic core or, alternatively, by a modified, magnetic-equivalent region having properties similar to a geometrically constricted region.
