  • Patent number: 7691518
    Abstract: A fuel cell stack (1) generates power by an electrochemical reaction between hydrogen and oxygen in plural stacked fuel cells (2a, 2b). Each fuel cell (2a, 2b) comprises an anode (26a) to which hydrogen is supplied, a cathode (26b) to which air containing oxygen is supplied, and a electrolyte membrane (20) which conducts hydrogen ions from the anode (26a) to the cathode (26b). The fuel cells (2a, 2b) comprise center cells (2a) and end cells (2b). By arranging the moisture absorption capacity of the end cells (2b) to be larger than that of the center cells (2a), flooding in the end cells (2b) which do not easily rise in temperature is prevented, and the low-temperature start-up performance of the fuel cell stack (1) is enhanced.

  • Patent number: 7691519
    Abstract: A fuel cell has a structure that an area of an opening at which a first flow passage opens toward a diffusion layer side of a fuel electrode is smaller than an area of an opening at which a second flow passage opens toward the diffusion layer side. This structure serves as a supply suppression structure for suppressing supply of liquid fuel from the first flow passage to the diffusion layer of the fuel electrode, and a discharge acceleration structure for accelerating discharge of discharge gas from the second flow passage. As compared with the case where the opening area of the first flow passage and the opening area of the second flow passage are equal to each other, the supply of liquid fuel from the first flow passage to the diffusion layer is suppressed so that liquid fuel is more easily filled in the first flow passage.

  • Patent number: 7691528
    Abstract: Electrical separators for batteries, especially lithium batteries, having a shutdown mechanism. A process for their production. An electrical separator is used in batteries and other systems in which electrodes have to be separated from each other while maintaining ion conductivity. Safety is very important in lithium batteries, since in contrast to other types of battery(Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a combustible solvent. A separator for lithium cells must possess a shutdown mechanism while not to be able to melt down. This is achieved by an electrical separator having a shutdown layer which consists of particles which melt at a desired temperature, close the pores of the separator, and so stop ion flow. Since the separator also comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator.

  • Patent number: 7691553
    Abstract: A kneaded material obtained by heating and melt-kneading a toner composition and a water-based medium containing water are put into a container of a granulating apparatus, and heated by a heater while agitating, to disperse the kneaded material into the water-based medium in its softened state. A temperature at which a loss tangent value of the kneaded material reaches a predetermined loss tangent value A, specifically, 0.5 or more and less than 5.0, is inputted to a granulating temperature input section as a setting granulating temperature T1. The heater is then controlled by a control section so that a granulating temperature as a temperature of the water-based medium measured by a thermometer reaches the setting granulating temperature T1 inputted to the input section. Accordingly, the granulating temperature as a temperature of the water-based medium, and thus a temperature of the kneaded material in the water-based medium is adjusted to T1.

  • Patent number: 7691554
    Abstract: An image forming method of forming a full-color image in which black can be expressed in addition to a color expressed by diffracted light. Each of plural diffraction gratings R, G, and B is transferred onto a base material from a transfer sheet in which the plural diffraction gratings R, G, and B are laminated, and the plural diffraction gratings R, G, and B are different from one another in a color of diffracted light observed in a particular direction. A black ink layer constituted by black ink is formed on the base material. Thereby, a color image is formed on the base material, in which a color to be expressed of each pixel is expressed by a combination of luminances of colors corresponding to the diffraction gratings R, G, and B and the black ink.

  • Patent number: 7691559
    Abstract: A method of performing immersion lithography on a semiconductor wafer is provided. The method includes providing a layer of resist onto a surface of the semiconductor wafer. Next, an edge-bead removal process spins the wafer at a speed greater than 1000 revolutions per minute and dispenses solvent through a nozzle while the wafer is spinning. Then, the resist layer is exposed using an immersion lithography exposure system.

  • Patent number: 7691564
    Abstract: Receptor mediated activation of heterotrimeric G-proteins is visualized in living cells by monitoring fluorescence resonance energy transfer (FRET) between subunits of a G protein fused to cyan and yellow fluorescent proteins. The G-protein heterotrimer rapidly dissociates and reassociates upon addition and removal of cognate ligand. Energy transfer pairs of G-proteins enables direct in situ detection and have applications for drug screening and GPCR de-orphaning.
