  • Patent number: 9791093
    Abstract: To realize a mechanism that can support an article at a desired position in such a way as to be able to move the article, with a thin, simple configuration. A load support mechanism 1 includes a fixed support section 2, which includes a fixed cam 8; a movable support section 3, which receives a load and can move vertically; a horizontal cam groove 13, which is provided in the movable support section; a cam follower member 15, which can move horizontally along the cam groove; a first spring 4, which is mounted between the fixed support section and the movable support section to support a load; and a second spring 18, which pushes the cam follower member horizontally and presses the cam follower member against a fixed cam surface 9 of the fixed cam. A reaction force of the fixed cam against the cam follower contains a vertical component depending on a height position of the movable support section, and the vertical component assists or reduces the spring's force to push up the load.

  • Patent number: 9758925
    Abstract: To prepare a shaped product comprising a thermal adhesive fiber under moisture and having a fiber aggregate nonwoven structure. In the shaped product, the thermal adhesive fibers under moisture are melted to bond to fibers constituting the fiber aggregate nonwoven structure and the bonded fiber ratio is not more than 85%. The shaped product has an apparent density of 0.05 to 0.7 g/cm3, a maximum bending stress of not less than 0.05 MPa in at least one direction, and a bending stress of not less than ? of the maximum bending stress at 1.5 times as large as the bending deflection at the maximum bending stress. The moistenable-thermal adhesive fiber may be a sheath-core form conjugated fiber comprising a sheath part comprising an ethylene-vinyl alcohol-series copolymer and a core part comprising a polyester-series resin. Such a shaped product can be used for a building board or the like since the shaped product has a high bending stress although the product is light and has a low density.

  • Publication number: 20160245349
    Abstract: The present invention is to provide a brake mechanism that prevents a significant decrease in braking force, even after years of being used with a repeat of braking and cancellation by a brake portion and a to-be-braked portion. A brake device 122 includes brake pads 145a, 145b, 146a, and 146b, which engage with or depart from a side of a first brake rail, on tips of upper and lower pairs of brake arms 141a, 141b, 142a, and 142b, which are provided in a rotatable manner across the first brake rail 31. When the brake pads 145a, 145b, 146a, and 146b are pressed against the brake rail 31, the brake pads are disposed in such a way as to be inclined so that a gap 304 emerges on a base end portion 302's side that is close to a fulcrum 144a's side.

  • Patent number: 9200390
    Abstract: In a nonwoven fiber assembly which comprises a fiber comprising a thermal adhesive fiber under moisture and in which the fiber are entangled with each other, the fibers are bonded at contacting points of the fibers by melting the thermal adhesive fiber under moisture to distribute the bonded points approximately uniformly, thereby obtaining a buffer substrate. The buffer substrate may further comprises a conjugated fiber comprising a plurality of resins which are different in thermal shrinkage and form a phase separation structure, and the conjugated fibers may have an approximately uniform crimps having an average curvature radius of 20 to 200 ?m and are entangled with the fibers constituting the nonwoven fiber assembly.
