  • Publication number: 20240151665
    Abstract: 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.

  • Patent number: 11511498
    Abstract: 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.

  • Patent number: 10431961
    Abstract: A spark plug includes: an insulator having an axial hole formed therein in an axial direction; a center electrode extending in the axial direction and having a rear end located within the axial hole; a metal terminal extending in the axial direction and having a front end located rearward of the rear end of the center electrode within the axial hole; a resistor arranged between the center electrode and the metal terminal within the axial hole; and a conductive seal layer that fills a space between the resistor and the center electrode in the axial. The conductive seal layer has a first layer portion located adjacent to the center electrode and a second layer portion located between the first layer portion and the resistor. The second layer portion has a thermal expansion coefficient different from and falling between those of the first layer portion and the resistor.

  • Patent number: 9506505
    Abstract: 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.

  • Patent number: 9457798
    Abstract: A hybrid vehicle determines whether or not the drive mode thereof is shifted from a series drive to an engine direct coupled drive with a power transmission engaging/disengaging portion applied, derives a rotational speed at a drive wheel side of the power transmission engaging/disengaging portion which corresponds to a driving speed as an applying rotational speed of an internal combustion engine at which the power transmission engaging/disengaging portion is applied, and applies the power transmission engaging/disengaging portion by controlling the operation of the internal combustion engine when a difference in rotational speed between the rotational speed of the internal combustion engine and the applying rotational speed becomes equal to or smaller than a predetermined value after the shift to the engine direct coupled drive is determined.
