Publication number: 20240006163Abstract: A monitoring method includes steps of (a) placing a substrate on a mounting stage of a processing chamber of a plasma processing apparatus; (b) supplying a pulsed wave of RF power with a predetermined duty ratio from an RF power supply connected to an antenna; and (c) monitoring a plasma state based on a converted value of a Vpp voltage of an output terminal of a matching unit arranged between the antenna and the RF power supply. The converted value of the Vpp voltage is obtained by converting the Vpp voltage of the output terminal voltage based on the duty ratio, the RF power, and correlation information indicating a correlation between the Vpp voltage and the RF power.Type: ApplicationFiled: May 19, 2023Publication date: January 4, 2024Inventors: Takeshi KOBAYASHI, Jun SATO, Takashi CHIBA

Patent number: 10922974Abstract: It is estimated whether or not each of landmarks is an object to be noted for travel assist control by using an estimation line EL set in the reference frame. The estimation line EL is set to be substantially parallel to a borderline BL. The borderline BL is a line a line which separates a drivable area and an undrivable area of a vehicle. It is estimated that the landmark located on a center line CL side is the object to be noted for travel assist control. It is estimated that the landmark located on a borderline BL side is not the object to be noted for travel assist control.Type: GrantFiled: September 28, 2018Date of Patent: February 16, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takashi Chiba

Patent number: 10843692Abstract: A technology is provided in which not only the information on the first preceding vehicle ILV but also the information on the preceding vehicle group LVG ahead of the first preceding vehicle ILV is applied to the travel assist control. Firstly, specification processing of a preceding vehicle LV on the own lane is executed (step S1). Subsequently, landmark information on the preceding vehicle LV is graded (step S2). Subsequently, a shielding ratio SR of the preceding vehicle LV belonging to the preceding vehicle group LVG is calculated for each preceding vehicle LV (step S3).
