  • Publication number: 20190249621
    Abstract: A purge system malfunction diagnosis device is configured to diagnose a malfunction in a purge system mounted on a vehicle. The purge system includes a canister, a purge passage, a purge valve capable of opening and closing the purge passage, an outside air passage configured to cause the canister to communicate with an outside air opening, an outside air valve capable of opening and closing the outside air passage, and a system pressure sensor configured to detect a pressure in the purge system. In a state where the outside air passage is closed, a diagnosis mode is executed on a basis of a relationship between the pressure in the purge system and an integrated value of flow rate estimates of a purge gas. In the diagnosis mode, a parameter to be used for diagnosing a malfunction in the purge system is adjusted in a case where the flow rate estimate is lower than a flow rate threshold.

  • Patent number: 10224220
    Abstract: Uniformity of a plasma process on a surface of a substrate is to be improved. In a plasma processing apparatus that processes a substrate by generating plasma from a processing gas introduced in a processing container, a ratio between an introducing amount of the processing gas introduced to a center portion of the substrate received in the processing container and an introducing amount of the processing gas introduced to a peripheral portion of the substrate received in the processing container is changed during a plasma process. Accordingly, a variation in an etching rate or the like between the center portion and the peripheral portion of the substrate may be reduced. Therefore, uniformity of the plasma process on the surface of the substrate is improved.
