  • Ink composition for plasma treatment detection, and plasma treatment detection indicator
    Patent number: 10400125
    Abstract: Provided is a plasma treatment detection indicator that enables the completion of plasma treatment to be confirmed from the color change of a color-changing layer by controlling the color change rate, regardless of whether the type of plasma is reduced-pressure plasma or atmospheric-pressure plasma, and regardless of the degree of plasma intensity; also provided is an ink composition for detecting plasma treatment for forming the color-changing layer. The ink composition for detecting plasma treatment comprises an organic dye and at least one member selected from the group consisting of a photopolymerization initiator, silica, and hydrophobic alumina.
    Type: Grant
    Filed: August 25, 2015
    Date of Patent: September 3, 2019

  • Insertion apparatus
    Patent number: 10314464
    Abstract: An insertion apparatus includes an insertion section, a rotational housing, a motor, and a controller. The motor rotates the rotational housing. The controller designates a rotational direction of the motor. The controller limits the rotational direction of the motor to allow the insertion section to move only in a removal direction when inspection control for inspecting an operation relative to an insertion direction of the insertion section is initiated.
