  • Patent number: 10761215
    Abstract: A code positioning part calculates a position of a subject vehicle and a receiver clock based on an orbit of a GNSS satellite in which an error indicated by a positioning reinforcing signal is corrected and a first corrected pseudorange being a pseudorange of the GNSS satellite in which an error indicated by the positioning reinforcing signal is corrected. A receiver clock bias error correction part determines a difference between a two-point range between a position of each of a plurality of GNSS satellites and the position of the subject vehicle and the first corrected pseudorange as an unknown error, and determines a receiver clock bias error of the pseudorange based on the unknown error. A code positioning correction part recalculates the position of the subject vehicle, using a second corrected pseudorange that is obtained by correcting the first corrected pseudorange using the receiver clock bias error.

  • Publication number: 20200206828
    Abstract: A cutting insert has cutting edges having the same shape and provided at respective corners of a polygon in rotational symmetry about the center axis of the polygon, is clamped in an upright position to a holder, and has a negative side rake angle on a rake face of a side cutting edge. A side cutting edge is present at an intersection ridge between a polygonal face and an outer peripheral face. The outer peripheral face includes a rake face of the cutting edge and a flank of an end cutting edge of another cutting edge different from the side cutting edge. The flank has a positive slope angle in opposition to a negative side rake angle of the side cutting edge. A breaker groove extending in a front-rear direction is formed in the rake face and cuts into the flank, in such a manner as to divide the rake face.

  • Patent number: 10600621
    Abstract: A plasma electrode is provided with an electrode plate, a ground plate, and an insulating plate arranged between the electrode plate and the ground plate. Protrusions of the electrode plate are arranged inside through holes of the ground plate and inside through holes of the insulating plate. One of the through hole provided on the center axes of the protrusions and the through hole provided around the through hole discharges a first processing gas to below the ground plate. The other of the through holes exhausts a gas existing below the ground plate. A second flow path around the protrusions supplies a second processing gas supplied via a first flow path to a gap between outer walls of the protrusions and inner walls of the through holes. The second processing gas supplied to the gap is converted into plasma by high frequency power applied to the electrode plate.
