A hydraulic mount includes: a container in which a high-viscosity fluid is liquid-tightly sealed; a rubber mount that is provided on an upper side of the container; a rod that slidably penetrates through the rubber mount; a damper plate that is provided to an end of the rod; a damping force generator that is provided by a clearance between the container and the damper plate; a main fluid chamber that includes an upper fluid chamber and a lower fluid chamber provided by dividing an interior of the container by the damper plate; a volume-variable secondary fluid chamber that communicates with the main fluid chamber; and a pressurizer that generates a differential pressure between the upper fluid chamber and the lower fluid chamber during the movement of the rod.

A vibration isolator includes layered rubbers interposed between a support body and a movable body, and a pair of dampers attached to the support body at one ends and to the movable body at the other ends. The layered rubbers are arranged to be spaced apart in an anterior and posterior direction and in a left and right direction, with reference to a direction in which an operator faces when seated. One of the dampers is arranged at a position corresponding to a middle of the left and right direction between the layered rubbers arranged in the left and right direction, and aligned in the anterior and posterior direction. The other one of the dampers is arranged closer to an anterior side than a middle of the anterior and posterior direction between the layered rubbers arranged in the anterior and posterior direction, and aligned in the lift and right direction.

Damping device

An injection locking type or MOPA type of gas laser device which requires only a small installation area and allows easy maintenance. For this purpose, the laser device includes a seed laser unit () for exciting a laser gas inside a laser chamber () and oscillating seed laser light () and an amplifier () for exciting a laser gas inside an amplifying chamber () and amplifying pulse energy of the seed laser light (), and allows the laser chamber () and the amplifying chamber () to be evacuated to the same side with respect to an optical axis of the seed laser light ().

The present invention is provided for considerably shortening the construction time of a building that is applied to nuclear power plants. When constructing the building, megablocks having a height that extends to a plurality of floors are produced, and together with combining those megablocks, concrete is poured inside them to form a wall member composed of a megawall structure of steel plate reinforced concrete construction. Alternatively, in addition to the wall megablocks, floor megablocks for forming the floor member of the building are used, and together with combining those megablocks, concrete is poured inside or above them to form a structural member (wall member and floor member) composed of a megawall structure of steel plate reinforced concrete construction.

An automobile fender protector to be attached to a fender panel for protection against splashing of mud. Essentially, the fender protector is a one-piece member which is formed of a synthetic resin and has a protector body in the form of an elongate plate curved correspondingly to a semicircular wheel-receiving opening of the fender panel, a mud guard portion as a rearward and downward extension of the protector body, and a fender molding portion in the form of a vertical wall extending upward from the outboard circumferential edge of the protector body. This fender protector may has an ornamental molding fitted into a circumferential slot in the outer surface of the fender molding portion.

The speed reduction means comprises a stationary hollow cylindrical body supporting for rotation about a common axis coaxially arranged rotary input body and rotary output body. A primary set of power transmitting balls is arranged at regular intervals in two mutually shifted rows forming a zig-zag pattern between the power input rotary body and the power output rotary body. A secondary set of power transmitting balls arranged at regular intervals in a single row is disposed between the power output body and the two rows of balls in the primary set. The bearing surface of the power input body defines an eccentric portion which compresses at one point the primary set of balls in radial direction thus displacing the secondary set of balls in axial direction to meander between the two rows of balls. One of the sets of balls is held in a fixed position by the stationary body and the single row in the secondary set includes n balls and each row in the primary set includes n+1 balls so that a speed reduction ratio of 1/(n+1) of the input rotational speed is obtained.
