Publication number: 20240151665Abstract: Provided is an inspection system capable of estimating electric characteristics of a sample with high accuracy regardless of an initial charging state of a wafer. The inspection system includes a charged particle beam device and a computer system, and inspects the electric characteristics of the sample. The inspection system evaluates initial charging of an inspection region including inspection patterns based on reference data indicating a secondary charged particle signal from a reference pattern corresponding to a plurality of pulse conditions. The reference pattern has the same electric characteristics as the inspection pattern and initial charging therein caused by electric charges that are not emitted according to a discharge time constant of the sample is negligible. The reference pattern is obtained by irradiating the reference pattern with a pulse charged particle beam under a plurality of pulse conditions.Type: ApplicationFiled: March 29, 2021Publication date: May 9, 2024Inventors: Yohei NAKAMURA, Naoko TAKEDA, Natsuki TSUNO, Satoshi TAKADA, Heita KIMIZUKA

Patent number: 11511498Abstract: A method for manufacturing a high-pressure tank including a reinforcing layer in which rims of both ends of a tubular member and rims of a pair of dome members are joined to overlap each other in a radial direction includes producing the dome members and producing the tubular member. The producing of the dome members includes producing a wound body on a mandrel, curing a resin contained in the wound body, shaving the wound body after the resin is cured to reduce, toward a split line, thicknesses of the rims of the dome members to be obtained by splitting the wound body, splitting the shaved wound body into the dome members by cutting the wound body along the split line, and demolding the dome members from the mandrel.Type: GrantFiled: June 24, 2021Date of Patent: November 29, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohei Takeda, Manabu Fujii

Patent number: 9506505Abstract: An engaging and disengaging controller for controlling the engagement and disengagement of a power transmission path by supplying a working oil of a predetermined pressure to an engaging and disengaging mechanism includes a valve for opening and closing a flow path of the working oil, and an opening/closing detection section which detects an opened or closed state of the valve. A malfunction detection apparatus for the engaging and disengaging controller includes an opening/closing control section for the valve, a time counting section which counts a predetermined time from the start of an opening/closing control, and a malfunction detection section which determines that the engaging and disengaging controller malfunctions in the case where the time counting section ends counting in such a state that the results of a detection by the opening/closing detection section do not coincide with the details of a control executed by the opening/closing control section.Type: GrantFiled: October 31, 2013Date of Patent: November 29, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Yohei Takeda, Hideaki Tsukahara
