  • Patent number: 8068770
    Abstract: An insertion passage 104Y for inserting a suction nozzle 73Y fixed to an image forming apparatus is provided on a holder 102Y, and a connecting passage 114Y that connects the insertion passage 104Y and a toner storage section 106Y of the holder 102Y is provided. After the toner sent from bottle 101Y to the holder 102Y falls towards the connecting passage 104Y, the toner flows into the suction nozzle 73Y through the connecting passage 114Y and is then discharged out of the holder 102Y. An airtightness between the insertion passage 114Y and the suction nozzle 73Y inserted into the insertion passage 114 Y is superior than an airtightness between the bottle 101Y and the holder 102Y engaged with the bottle 101Y.

  • Patent number: 6837475
    Abstract: A valve-operating device for an engine includes a camshaft which is disposed on one side of a plane including axes of an exhaust valve and an intake valve and which has an axis substantially perpendicular to the plane. The camshaft and the exhaust and intake valves are connected to each other through a first rocker arm and a second rocker arm which are swingably carried on a rocker shaft disposed substantially perpendicular to the plane. The camshaft is formed with a large-diameter exhaust cam and a small-diameter intake cam adjoining a portion of the exhaust cam on the side of the plane. The exhaust and intake rocker arms are provided with arm portions extending in an axial direction of the camshaft to come into sliding contact with outer peripheral surfaces of the exhaust and intake cams, respectively. Thus, it is possible to open and close the exhaust and intake valves with inherent opening and closing timings, while easily avoiding interferences among components.
