  • Publication number: 20080113253
    Abstract: A separator comprises a resin layer formed by electrodeposition in such a way as to cover a metal substrate having a groove in at least one surface thereof. The resin layer is composed of an electrically conductive material and a water-repellent material, or the resin layer contains an electrically conductive material, and is designed such that at least a portion of the resin layer positioned at the groove is covered with a water-repellent layer. Consequently, it is possible to provide a separator for a polymer electrolyte type fuel cell, which is less susceptible of flooding, has improved strength and corrosion resistance, and can be fabricated at lower costs.

  • Publication number: 20080001342
    Abstract: Disclosed is a sheet feeder in which sheets are fed by a feeding member from a tray on which the sheets have been loaded. When the tray is driven by a drive unit to lift up the tray from a sheet replenishment position to a position at which sheets can be fed, a first sensor senses that the top sheet on the tray is situated at a prescribed position. Response to this sensing of the first sensor the drive unit performs a predetermined intermittent driving for lifting the tray. It is determined based upon outputs from the first and second sensors whether or not a sheet is present on the tray.

  • Publication number: 20070238005
    Abstract: The object of the invention is to provide a separator for fuel cells which is of improved strength and corrosion resistance and facilitates the assembling of unit cells. The separator comprises an electrically conductive resin layer formed by electrodeposition in such a way as to cover a metal substrate and a gasket component. The resin layer contains an electrically conductive material. The separator of the invention has thus an enhanced corrosion resistance, makes some considerable improvements in the assembling work efficiency of unit cells, and makes sure higher strength because of the use of the metal substrate.

    Abstract: A data management apparatus, according to a request of an application program, lends a pointer for reading out a data from a data field stored a plurality of data. An address of the data field corresponding to the lent pointer is stored a lending pointer table. When the application program accesses a data stored in the data field, the data management apparatus receives the pointer from the application program, reads out an address corresponding to the received pointer from the lending pointer table, and reads out the data corresponding to the read address from the data field. The read data is given to the application program.
