Abstract: Provided is an electron-emitting device using a carbon fiber as an electronic member. A carbon fiber through which a cathode electrode and a control electrode are short-circuited is removed to obtain an electron-emitting device having a uniform electron emission characteristic. A first electrode including a plurality of fibers each containing carbon and a second electrode are prepared. Then, a voltage is applied between the first electrode and the second electrode with a state where a potential of the first electrode becomes higher than a potential of the second electrode to remove a carbon fiber through which the first electrode and the second electrode are short-circuited.

The substrate on which a catalyst layer is formed is disposed in a reaction container. An atmosphere in the reaction container is set to be a reduced pressure atmosphere including a carbon containing gas having a partial pressure of 10 Pa or less, and the substrate is heated in the atmosphere to grow carbon fibers on the catalyst layer.

Abstract: In manufacturing surface conduction electron-emitting devices, a polymer thin film is arranged to connect a pair of electrodes and then transformed into a low resistivity film (carbon film) by irradiating the polymer film with an energy beam. The energy beam irradiation is scanned over the polymer films plural times so that heat due to the energy beam irradiation does not affect other members which constitute the device and also the processing time for carbonization of polymer film is reduced.

Abstract: An angular position detection apparatus, which can improve a detection accuracy of the angular position by improving a linearity of an output characteristic with respect to an angular position detection apparatus, and to downsize an outer size thereof. A permanent magnet is fixed to a side surface of a rotor core, which integrally rotates with a detection target object. An inner surface of a cylindrical portion of the rotor core is closely confronted with an outer surface of a stator core. Thus, the angular position detection apparatus is formed as a radial gap type in which magnetic flux is gone through an air gap G1 between the cylindrical portion and the stator core along a radial direction. A magnetic flux detection gap portion is formed at a center portion of the stator core so as to go through toward a diametral direction. A Hall IC is arranged in the magnetic flux detection gap portion. The permanent magnet is magnetized so that lines of magnetic force therein are parallel with each other.

Abstract: A system and method for presenting additional movie/DVD content listings of the same genre as a DVD movie, after a viewer has watched the DVD movie. A personalized bulletin board screen can be presented on a TV, with the screen listing additional content likely to be of interest to the viewer, based on the movie just watched. The bulletin board screen can be updated periodically over the Internet, such that an older DVD can be played and an updated bulletin board screen displayed with content that might, for example, star an actor in the just-watched DVD movie, or otherwise be of interest to a person who just watched the DVD movie.

Abstract: A method for separating specific hydrocarbons from a hydrocarbon mixture of hydrocarbons using a membrane made of a fluorine-containing polyimide resin having high separation ability with regard to certain hydrocarbons, and a high resistance to hydrocarbon is disclosed. The method is of high practicability with regard to performance and cost. Certain hydrocarbons permeate selectively and are separated by bringing a hydrocarbon mixture into contact with a membrane having a fluorine-containing polyimide resin as its main component, whose main component is the minimum repeating unit expressed by The mixture is passed through the membrane, thereby selectively permeating, for example, unsaturated hydrocarbons. The main component of the membrane is a fluorine-containing polyimide resin with a fractional free volume in the range of 0.130-0.175.
