  • Patent number: 11369528
    Abstract: Provided is a stretchable laminate that achieves both a weight reduction and an extension strength, and that can be stably produced. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention includes: an elastomer layer; and an olefin-based resin layer arranged on at least one side of the elastomer layer, wherein when a longitudinal direction of the stretchable laminate is defined as an MD direction and a direction perpendicular to the longitudinal direction is defined as a CD direction, a ratio [10% extension strength in MD direction (N/30 mm)]/[basis weight (gsm)] of the stretchable laminate is 0.14 (N/30 mm·gsm) or more.

  • Patent number: 10828839
    Abstract: Provided is a method of producing a layered article by which a sufficient production speed can be achieved, and preferably, a variation in fusion strength can be suppressed and hence a variation in product quality can be reduced. The method of producing a layered article of the present invention includes fusing at least part of a single-layer body or a laminate including at least one layer including a non-woven fabric of fiber having a fiber diameter of 100 ?m or less through ultrasonic welding.

  • Publication number: 20110099839
    Abstract: A drying apparatus for manufacturing a pressure-sensitive adhesive tape in which a pressure-sensitive adhesive layer is formed on a strip-shaped long tape base material is provided. The drying apparatus dries coating agent coated at least on one surface of the tape base material. The tape base material that is transferred in a lengthwise direction thereof is spirally wound around a cylinder body from one end side of the cylinder body to the other end side of the cylinder body in a slidable state. The cylinder body is formed with a plurality of air holes on an entire circumferential wall thereof, around which the tape base material is spirally wound, the air holes through which warm air or hot air flows from the inside of the cylinder body to the outside of the cylinder body.

  • Patent number: 5900140
    Abstract: In a fuel filter module for introducing fuel from a fuel inlet into a casing and for removing foreign matter from the fuel by passing the fuel through a fuel member and for discharging the fuel through a fuel outlet to the outside of the casing, and the casing is formed to have a D-shaped cross section. With this construction, the outer diameter of the casing is not increased even when an accessory is assembled on the outside plane wall of the D-shaped casing. The casing accommodates a filter member of C-shaped cross section. The center of a C-shaped sealing member provided for sealing the upper edge of the filter member is offset from the center of the casing. By thus offsetting, sufficient areas for fuel inlet and outlet can be ensured without increasing the size of the casing.
