Abstract: An air shock absorber includes seal members that maintain the sealing performance and slidability of the seal members. The air shock absorber includes a cylinder and a piston. The cylinder contains gases and is divided by the piston into a high pressure gas chamber and a low pressure gas chamber. A first seal member extends in a circumferential direction of the piston along its outer periphery. A second seal member is located on the outer periphery of the piston closer to the high pressure gas chamber than the first seal member is. A surface of the first seal member includes a groove. A surface of the second seal member faces the surface of the first seal member and includes a groove.

Abstract: A steering damper can generate a smaller damping force according to a first damping force characteristic or a larger damping force according to a second damping force characteristic by controlling a flow of hydraulic oil during a steering operation of a steering member. When the associated vehicle is running at a relatively low or medium speed and is not accelerating, and if an operational speed of the steering damper is lower than a predetermined value, damping force according to the first damping force characteristic can be generated in the steering damper. On the other hand, when the operational speed of the steering damper is equal to or higher than the predetermined value, damping force according to the second damping force characteristic can be generated in the steering damper.

Abstract: A wheeled vehicle has a front suspension unit coupled with a body frame to suspend a front wheel. The front suspension unit allows the front wheel to move relative to the body frame. The front suspension unit has a pair of front suspension members coupled with each other. A rear suspension unit is coupled with the body frame to suspend a rear wheel. The rear suspension unit allows the rear wheel to move relative to the body frame. A hydraulic system inhibits a position of the body frame from changing relative to the ground. The hydraulic system has a first hydraulic device to generate hydraulic pressure in response to the movement of the front wheel relative to the body frame. A second hydraulic device generates hydraulic pressure in response to the movement of the rear wheel relative to the body frame. A hydraulic pressure adjusting device connects the first and second hydraulic devices with each other.

Abstract: Adhesive compositions based on chlorinated polyolefins having chlorine contents greater than about 60 percent and molecular weights greater than about 500. The adhesive compositions contain the chlorinated polyolefin and a crosslinking agent. The chlorinated polyolefins are advantageous in that they can be prepared in an environmentally acceptable manner and can be utilized as a substitute for the traditional chlorinated natural rubber materials utilized in adhesive compositions without compromising adhesive performance. Preferred chlorinated polyolefins are prepared by a process involving the dispersion and chlorination of high surface area polyolefinic particles in an aqueous medium.

Abstract: The present invention relates to an auto-switch which is used for a control circuit of a power window for moving automobile window glass up and down using an electric window motor, and has a manual/automatic contact, wherein the auto-switch is operably by a single operating knob. In the auto-state, the auto-switch can mechanically retain the manual/automatic contact at a closed state, and can always reset the operating knob to the neutral position.
