  • Publication number: 20090277427
    Abstract: A diagnostic device for a fuel vapor treatment system having: a canister that captures fuel vapor generated in a fuel tank; a purge passage for purging fuel vapor from the canister to an intake passage of an internal combustion engine; a purge valve provided in the purge passage to adjust a flow rate of fuel vapor; a processing device that depressurize an fuel vapor path extending from the fuel tank to the purge valve via the canister by a pump and performs a diagnostic processing for diagnosing a leak of fuel vapor from the fuel vapor path based on a change in pressure in the fuel vapor path during depressurization; and an angle detection device that detects an angle of inclination of the vehicle. The processing device determines, based on an inclination angle of the vehicle detected by the angle detection device, whether the diagnostic processing can be performed.

  • Patent number: 7404814
    Abstract: An infusion vessel has a vessel body having an internal cavity to serve as an infusion medium space, a cylindrical discharge mouth continuing from a lower portion of the vessel body, a medicine chamber disposed in the discharge mouth and kept airtight against ambient air, and a separator intervening between the infusion medium space and the medicine chamber so as to keep the space in a liquid-tight state against the holder. The separator is subject to displacement, rotation or deformation such as to bring the infusion medium space into communication with the medicine chamber, so that the infusion vessel can be made ready for use by conducting a simple operation to mix the medicine with the infusion medium that have been separated from each other within the vessel during its normal state before use.
