    摘要: Disclosed are a gas diffusion electrode for an electrochemical cell which comprises a catalyst layer formed by binding, by means of poiytotrafluoroethylene, catalyst-supporting carbon black and catalyst-non-supporting carbon black having a fluorinated polyolofine film on substantially whole surface, the catalyst layer being integrated on a substrate, and a process of preparing same. Since the carbon black employed for the formation of the gas network in the catalyst layer of the gas diffusion electrode having the above constitution in accordance with the present invention is completely hydrophobically treated, no electrolyte permeates this portion and the carbon black exhibits high hydrophobicity so that the wet-proofing is maintained even after the long operation period to enable the gas supply to the catalyst particles so as to provide the gas diffusion electrode with a long life and high electrode performances.

    摘要: Disclosed is a process of preparing fluorinated material which comprises thermally treating the mixture of carbon black and hydrocarbon polymer compound powder for covering the surface of the carbon black with the latter and fluorinating the hydrocarbon polymer compound. The thermal treatment can be conducted in two stages.The fluorinated material prepared in accordance with the present invention can provide much more pore volumes acting as gas networks in, for example, an electrode which exhibits high gas permeability or gas supplying ability. Further, the hydrophobicity is as high as that of the material prepared in accordance with mixing carbon black with hydrocarbon polymer compound dispersed in an organic solvent, and is higher than that of the conventional mixture of carbon black and polytetrafluoroethylene particles. The fluorinated material is preferably employed to a fuel cell as gas network material.

    摘要: A powder container includes a rotatable powder storage to store powder for image formation, a conveyor to transport the powder inside the powder storage, and a scooping portion to scoop the powder inside the powder storage. The conveyor transports the powder in a powder conveyance direction parallel to a rotation axis of the powder storage toward an opening at one end of the powder storage. The scooping portion causes the powder to flow to the opening. The scooping portion includes a scooping face extending from an inner face of the powder storage toward the rotation axis of the powder storage, and a rim disposed along an inner end of the scooping face in a diameter direction of the powder storage, and at least a portion of the rim protruding downstream beyond the scooping face in a rotation direction of the powder storage.

    摘要: A reflector apparatus includes reflectors, which respectively radiate reflected waves in predetermined polarization directions. A polarized wave information reading circuit fixed to a moving body radiates a radio wave toward the reflecting apparatus from a transmitting antenna, receives reflected waves from the reflecting apparatus, and generates a received level difference signal that corresponds to a polarization direction of the received reflected waves. A position calculating circuit calculates a position of the polarized wave information reading circuit based on the received level difference signal.
