  • Patent number: 9511689
    Abstract: A seating apparatus for a vehicle, in which a seat cushion supported on the vehicle body by a link member can be flipped up toward the front of the vehicle from a use position and which includes a locking mechanism that operates only when the seat cushion is acted upon by an inertial force greater than a predetermined force in the longitudinal direction of the vehicle, to temporarily prevent the seat cushion from flipping up. The locking mechanism includes a locking plate supported on the seat cushion and rockable in the longitudinal direction of the vehicle between a normal position and a rocked position, and a spring for urging the locking plate toward the normal position. The locking plate locks the seat cushion to the link member when it is moved inertially to the rocked position against the force of the spring, to prevent the seat cushion from flipping up, and the locking plate unlocks the seat cushion when it is located in the normal position.

  • Patent number: 8163060
    Abstract: The heat conductivity of an aluminum composite material containing a fibrous carbon material is enhanced. In order to realize this, a spark plasma sintered body having a fibrous carbon material compounded in a metal matrix powder of aluminum or the like is fabricated. At the time of fabrication, an aluminum powder serving as a matrix mother material is compounded with an Al alloy powder such as an Al-12Si powder having a melting point lower than the sintering temperature of the mother material. During the process of sintering the aluminum powder, the Al alloy powder is melted, whereby the heat conductivity between the aluminum powder particles and between the aluminum powder particle and the fibrous carbon material is improved.

  • Patent number: 8037792
    Abstract: A device for mounting a cover of a cutting blade to a riving knife may have an engaging member for releasably engaging at least a part of the riving knife from both sides, in a direction of thickness of the riving knife. The engaging member is manually operable without any additional tools. A device for mounting a riving knife to a table saw may include a manually operable lock member and a biasing member. The biasing member is arranged and constructed to normally bias the lock member towards a lock position. The riving knife may be divided into a first knife portion and a second knife portion. A positioning device may position the first knife portion and the second knife portion substantially within a single plate.

  • Patent number: 7882771
    Abstract: A dust-collecting device for collecting cutting chips produced by a cutting device has a separator for separating the cutting chips from the carrier air by utilizing the force of gravity upon the cutting chips. A dust container collects the cutting chips separated by the separator. The separator includes a separator body having a cutting chip discharge pipe and an air discharge pipe. After separation the carrier air is discharged upward from the separator body via the air discharge pipe. The separated cutting chips are discharge downward from the separator body via the cutting chip discharge pipe. The dust container is connected to the cutting chip discharge pipe.
