  • Patent number: 7195345
    Abstract: An ink cartridge for a printing apparatus providing ink to a print head through a tapered ink supply needle and removably attached to the print head. The ink cartridge comprises an ink chamber for containing ink, an ink supply port, a packing member and a valve device. The ink supply port supplies ink from the ink chamber to the print head of the printing apparatus, the ink supply port comprising an external opening. The packing member is provided in the ink supply port and forms an ink channel for allowing a flow of ink. The packing member seals the ink supply needle of the printing apparatus by fitting therewith. The valve device is contained in the ink supply port and elastically abuts against the packing member. The valve, device selectively opens and closes the ink channel in conjunction with the ink supply needle.

  • Patent number: 7101513
    Abstract: A fuel supplying apparatus for maintaining a stable supply of a mixed water-methanol solution while preventing water from freezing in a cold climate, and for immediately supplying a mixed water-methanol gas that has a composition which is outside of the high-rate reaction region during the starting/stopping operation of the reformer when the control tends to be unstable. The methanol reforming apparatus that generates a hydrogen-rich gas by reacting a mixed gas of water, methanol and air on a catalyst is supplied with the fuel from a fuel supplying apparatus comprising a mixed water-methanol solution tank wherein the molar ratio of water and methanol used for reforming is controlled to a predetermined value, a mixed water-methanol solution tank wherein the molar ratio of water and methanol is controlled to 4.6 or higher, and a switching means that switches the mixed water-methanol solution tank used as a fuel source according to the conditions of operation of the methanol reforming apparatus.
