  • Patent number: 12091586
    Abstract: The two-part curable adhesive composition contains a main agent (A) containing a urethane prepolymer (a1) and a residual polyisocyanate (a2), and a curing agent (B) containing a polyol compound (b1) and a polyamine compound (b2). The urethane prepolymer (a1) is made by reacting in an equivalent ratio of an isocyanate group in a raw material polyisocyanate to a hydroxy group in a polytetramethylene ether glycol being 2.05 or greater. The equivalent ratio of an isocyanate group in the main agent (A) to an active hydrogen group in the curing agent (B) is from 0.5 to 4.

  • Publication number: 20240262256
    Abstract: A sensor-equipped seat (1) is provided with a seating-surface seat cushion (10) that comprises: a first seating-surface seat cushion (12) having an accommodation recess (80); and a second seating-surface seat cushion (15) which is accommodated within the accommodation recess (80). Disposed between a first pressing surface (82b) of the accommodation recess (80) in the first seating-surface seat cushion (12) and a second pressing surface (15a) of the second seating-surface seat cushion (15) is a flexible sensor (3) that detects seating condition of a seated person or biological information of the seated person. The first seating-surface seat cushion (12) and the second seating-surface seat cushion (15) are pre-compressed in the stacking direction. Pre-compression is applied to the sensor (3) by compressive reactions of the first seating-surface seat cushion (12) and the second seating-surface seat cushion (15).

  • Patent number: 11602139
    Abstract: A fishing rod includes a rod section and a fitting having a securing portion, the fitting being firmly secured to the rod section without inhibiting bending of the rod section, the securing portion having an excellent outer appearance. On a securing portion of a fishing line guide placed on the rod section, a prepreg sheet formed of plain-woven reinforcement fibers impregnated with a thermosetting resin is wound to secure the fishing line guide. The prepreg sheet is wound and secured so that, with respect to an axial direction, reinforcement fibers are in oblique directions, and intersecting angles of the reinforcement fibers in a winding region on a part of the rod section located beyond a distal end of the securing portion are smaller than those of the reinforcement fibers in a winding region on the securing portion.
