  • Patent number: 11191326
    Abstract: A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.
    Type: Grant

  • Patent number: 9161635
    Abstract: A first member includes a first fixing portion on which a sheet edge is fixed, a holder continuous with an end of the first fixing portion, a first recess that is defined in the holder and has an opening in a continuous direction of the first fixing portion, and a support portion that is formed opposite the first fixing portion across the opening of the first recess of the holder. A second member includes a second fixing portion on which the other sheet edge is fixed, a held portion continuous with an end of the second fixing portion. When the held portion is inserted into the first recess, the support portion is brought into contact with a surface of the second fixing portion.

  • Patent number: 8701253
    Abstract: A slide fastener in which a fastener element has first and second leg portions continuously disposed at both ends of the coupling head is folded in half at its center, and the first leg portion is attached to a coupling element attaching portion of a fastener tape by a sewing thread. A vulnerable portion which is cut out into a V is formed on the bent end face of the coupling head.

  • Patent number: 8590117
    Abstract: A slide fastener which withstands a predetermined lateral pulling force in a usual usage and is cloven when an excessive lateral pulling force is applied at the time of airbag inflation, wherein the slide fastener in which a plurality of attachment leg portions of coupling teeth, on each of which a coupling head formed to have a relatively large width and the attachment leg portions extending from the coupling head are formed, are attached on a coupling tooth attaching portion of each of a pair of fastener tapes on right and left with a predetermined pitch along a tape longitudinal direction is configured to satisfy a relationship 0.4?(2×H?P)/P?0.1 between a summit height H [mm] of the coupling head formed to have a relatively large width and a pitch P [mm].

  • Publication number: 20110041296
    Abstract: The present invention provides a slide fastener in which a broken part of a coupling element is not separated easily at the time of a forced cleavage when an airbag is expanded and having an excellent appearance. In the slide fastener (110) in which coupling elements (12, 113) each having a first leg portion and a second leg portion (72; 73) which are forked and extended from a coupling head (70) are sewed to a fastener tape (16, 17) thereof, a V-shaped cutout portion is formed at a single position in the range from a sewing line (84) on a first sewing portion (74) of the first leg portion (72) up to a sewing line (85) on a second sewing portion (75) via a coupling head (70) so as to form a vulnerable portion (80) whose breaking resistance is weakened. Consequently, even if an excessive lateral pulling force is applied to the slide fastener (110), so that the coupling element (12) is broken at the vulnerable portion (80), a broken part of the coupling element (12) is held on the fastener tape (16, 17).

  • Patent number: 4950462
    Abstract: CO is recovered from a CO-containing gas by contacting a CO-containing gas with a non-aqueous CO-absorbing solution comprising 3 to 6 moles/l of hexametaphosphateamine, 1 to 4 moles/l of cuprous chloride, 0.1 to 1% by weight of water and an organic solvent, thereby absorbing CO into the CO-absorbing solution from the CO-containing gas, and then atomizing the CO-absorbed solution, thereby stripping CO from the CO-absorbed solution and obtaining a CO gas, while recycling the CO-freed absorbing solution to the absorption of CO from the CO-containing gas with remarkable reduction in the corrosion rate on apparatus materials without impairing the CO absorption, and use of a two-fluid, simultaneous atomizing means for atomizing the CO-absorbed solution together with the vapor of the organic solvent can improve the CO stripping rate, and reduce the CO recovery cost.
