  • Publication number: 20240326493
    Abstract: An electronic apparatus includes: an apparatus body; a door configured to be displaced to an opened state in which the door is opened relative to the apparatus body and a closed state in which the door is closed relative to the apparatus body; a cable provided between the apparatus body and the door; and a cable protecting unit configured to protect the cable. The cable protecting unit includes: a base-portion member; and a movable member provided slidably relative to the base-portion member. When the door is displaced from the closed state to the opened state, the movable member slides relative to the base-portion member to increase a length by which the movable member extends from the base-portion member.

  • Patent number: 10677199
    Abstract: An anomaly determination device for an evaporated fuel processing device comprises: an evaporated fuel processing device (60) including a canister (61), a purge passage (62) and a purge valve (66); a first pressure sensor (43) and/or a second pressure sensor (45) for acquiring a purge downstream pressure, a third pressure sensor (53) for acquiring a canister internal pressure, and a PCM (70) that calculates a purge flow rate per unit time based on the purge downstream pressure and an opening degree of the purge valve (66), and calculates an integrated purge flow rate by integrating the purge flow rate, so as to perform an anomaly determination for the evaporated fuel processing device (60) based on the canister internal pressure and the integrated purge flow rate. The PCM (70) uses the canister internal pressure when the integrated purge flow rate becomes a predetermined flow rate or more.

  • Patent number: 10385791
    Abstract: A PCM (60) performs a catalyst early warming control (AWS control) for accelerating warm-up of a catalytic device. When the catalytic device (35) is not in an activated state and a vehicle is traveling, the PCM (60) is configured to perform: a fuel injection control to inject fuel such that a homogeneous fuel-air mixture can be formed in a combustion chamber (11) of an engine (10) so as to generate a homogeneous combustion; an intake air amount control to increase intake air amount; and an ignition control to retard ignition timing from a reference ignition timing. In addition, the PCM (60) is configured to vary ignition timing retard amount corresponding to a difference between the ignition timing retarded by the ignition timing control and the reference ignition timing, in accordance with engine speed and/or engine load.

  • Patent number: 8664405
    Abstract: The object is to provide a stable SM-108 derivative, which is effective as a carcinostatic agent, particularly an SM-108 derivative having good storage stability. An SM-108 compound having good storage stability can be produced by producing an organic sulfonic acid salt compound of SM-108. Further, a crystalline SM-108 compound containing a trace amount of an organic carboxylic acid can be produced by using an aqueous solution of the organic sulfonic acid salt of SM-108, and by adding an alkali metal salt of an organic carboxylic acid to the aqueous solution to neutralize the aqueous solution and then causing the crystal precipitation in the solution.
