Abstract: An object of the invention is to provide a carbon nanotube electrode which is suited to quantity production and advantageous in cost, and a process for producing the same.  When carbon nanotubes on respective catalyst particles 12 on an endless belt 3 gradually fall down to a horizontal position while moving around a driven drum 2 after traveling from a CVD  zone to a transfer zone with the movement of the belt, the carbon nanotubes 11 have their outer ends pressed against a conductive film 8. The conductive film 8 is sent out from a film feeder 9 downward and heated by a heater 10 to a temperature not lower than the softening temperature of the film to below the melting temperature thereof. The carbon nanotubes 11 are transferred from the catalyst particles 12 to the conductive film 8 substantially perpendicular to the film surface by being pressed against the conductive film 8 in this way.

Abstract: In manufacturing an aspherical seamless capsule comprises, firstly, a seamless capsule C1 having a filler encapsulated with a shell membrane is provided, then it is dried in a dryer 12 until a predetermined percentage content of solvent in the shell membrane reaches a predetermined value. Subsequently, the seamless capsule is heated by a heater 38 so that the shell material may get to a semi-sol state. Then, the heated seamless capsule is formed into an aspherical shape using a forming machine such as a compression molding machine. Because the spherical seamless capsule has a shell membrane which is dried to get semi-sol so that it may have a reduced elasticity and a shortened stress relaxation time, the capsule can be formed in a short time and suppressed from restoring to the original spherical shape. The semi-sol shell membrane has almost no change in properties, and so allows easiness in temperature control for treatment. The aspherical capsule after being formed does not or rarely need drying, resulting in wrinkle resistance and little variation in shape brought on the surface of the shell membrane.

Abstract: A method and apparatus for real-time polarization difference imaging (PDI) video including an imaging lens focusing the light on to a collimating lens, whereby the stimulus beams becomes parallel before striking a polarizing beam-splitter. Segregated orthogonally polarized components of the stimulus are then focused on imaging sensors, and one sensor's output signal is subtracted from the other, thereby creating a real-time polarization difference video image. The efficiency of such a system is greatly enhanced by illuminating the target with a polarized light source (with a polarization orientation matching one of those used in the PDI process), and PDI-enhanced targets can be constructed with surface features and textures optimised to result in a maximum return signal strength and spatial contrast.
