  • Patent number: 10854431
    Abstract: A plasma processing method includes executing an etching process that includes supplying an etching gas into a process container in which a target substrate is supported on a second electrode serving as a lower electrode, and applying an RF power for plasma generation and an RF power for ion attraction to turn the etching gas into plasma and to subject the target substrate to etching. The etching process includes applying a negative DC voltage to a first electrode serving as an upper electrode during the etching to increase an absolute value of self-bias on the first electrode. The etching process includes releasing DC electron current generated by the negative DC voltage to ground through plasma and a conductive member disposed as a ring around the first electrode, by using a first state where the conductive member is connected to a ground potential portion.

  • Patent number: 10837409
    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.

  • Publication number: 20200284181
    Abstract: A freezing diagnosing device to be installed in an engine includes an ambient temperature sensor, a liquid temperature sensor, and a freezing determination unit. The ambient temperature sensor detects an ambient temperature. The liquid temperature sensor detects the temperature of a liquid held in the engine. The freezing determination unit determines that a freezing state of a pipe coupled to a pressure sensor in the engine is established when one or both of a first condition and a second condition are satisfied. The first condition is that the ambient temperature detected by the ambient temperature sensor is equal to or less than a first threshold. The second condition is that the temperature of the liquid detected by the liquid temperature sensor is equal to or less than a second threshold.
