Abstract: A seat cushion part includes a base fabric extending between and looped around a front edge frame and a rear edge frame, and having an upper layer part and a lower layer part which are provided apart from each other in an up-down direction. Wire members of metal are provided respectively on side edge portions of the base fabric, and coil springs are spring members each extending between an end portion of the wire member and the front edge frame or the rear edge frame. A load further applied due to vibration, impact, and so on causes the upper layer part to come into contact with the lower layer part to also displace the lower layer part in the up-down direction. Consequently, the coil springs connected through the wire members extend/contract, and their elastic force acts.

Abstract: A method for producing a microbiologic agent is described. The method includes a step of adding biomass containing a target compound-degrading microorganism and an inorganic microparticle carrier to a medium containing a target compound. The microorganisms included in the biomass are carried on the inorganic microparticles, and the medium is cultured while monitoring an abundance ratio of the target compound-degrading microorganism in microorganisms carried on the inorganic microparticle carrier. After the abundance ratio of the target compound-degrading microorganism reaches a predetermined value, the inorganic microparticle carrier carrying the target compound-degrading microorganism is collected to obtain the microbiologic agent.

Abstract: In a crawler crane, while a fly jib is in use, the fly jib is suspended from a coupling flange by a jib raising/lowering wire rope that is wound around a sheave, the sheave being slidably attached to a tip end side section of the fly jib. If the sheave is caused to slide by a jib raising/lowering cylinder attached to the fly jib, the fly jib suspended from the coupling flange by the jib raising/lowering wire rope inclines with respect to a boom. The raising/lowering mechanism of the fly jib is installed on the fly jib side, thus making it possible to easily perform work to extract/store the fly jib.
