  • Patent number: 12031240
    Abstract: A fiber for artificial hair formed of a polyvinyl chloride-based resin composition. The fiber for artificial hair has a value X1 of a loss tangent tans at 70° C. of 0.06 or more and 0.12 or less, when dynamic viscoelasticity is measured under the following conditions, and has a peak in a temperature range of 90° C. or higher and 110° C. or lower. (Dynamic viscoelasticity measurement conditions) The measurement is performed by sandwiching a bundle of 40 fibers for artificial hair that are arranged at a heating rate of 4° C./min and a frequency of 1 Hz.

  • Publication number: 20240075736
    Abstract: A printing apparatus includes a mounting unit, a tank, a pump, a detection unit, an obtainment unit, and a control unit. The mounting unit is configured so that a head that ejects ink can be mounted in a replaceable manner. The tank contains ink to be supplied to the head via a tube. The pump discharges ink to an outside of the head. The detection unit detects that the head mounted on the mounting unit has been replaced. The obtainment unit obtains information of a usage history which indicates whether or not the head mounted as a replacement has been used. The control unit controls a discharge operation, which is performed by the pump after head replacement, to be changed based on the information of the usage history.

  • Patent number: 11731434
    Abstract: A printer includes a record section, a discharge section, a mount section, a movable rib, a move section, and a control section. The record section records on a sheet by ejecting an ink to the sheet. The discharge section discharges the sheet. The mount section has a mount surface on which the sheet discharged is mounted. A movable rib is configured to protrude from the mount surface and supports the sheet. The dimension of the movable rib in an A-direction is larger than the dimension thereof in a Y-direction. The move section moves the movable rib in a C-direction. The control section controls, based on temperature and humidity information, movement of the movable rib made by the move section.
