    • An anti-skid apparatus for installation in a vehicle braking system having a regulator valve for producing a hydraulic power pressure in accordance with a hydraulic braking pressure from a master cylinder. A control cylinder is disposed in a hydraulic circuit connecting the master cylinder to a wheel brake cylinder, and comprises a cylinder body having a cylinder bore defined therein and a piston axially slidably disposed within the cylinder bore. This piston forms at its one end a pressure chamber communicating with the wheel brake cylinder, and is applied at its the other end with the hydraulic power pressure from the regulator. Disposed in the control cylinder is a normally open cut-off valve which normally permits the flow of the hydraulic braking pressure from the master cylinder into the pressure chamber and blocks the flow of the hydraulic braking pressure when the piston moves to an extent more than a predetermined distance from its initial position for decreasing the volume of the pressure chamber. And, a changeover valve is disposed between the regulator valve and the control cylinder, and applies the hydraulic power pressure to the piston or discharges it from the control cylinder.

    • A master cylinder is provided on the cylinder body with a reservoir-receiving mouth formed near the border of the section of of a large diameter and the section of a small diameter of a stepped bore, a through hole being formed between the bottom surface of the reservoir-receiving mouth and the first pressure chamber, a compensation hole being formed between the bottom surface of the reservoir-receiving mouth and the second pressure chamber, a valve seat fitted in and fixed to the reservoir-receiving mouth and having an internal hole formed therein, a check valve provided within the reservoir-receiving mouth between the bottom surface of the reservoir-receiving mouth and the valve seat with the valve element being pressed against a resilient member fixed to the valve seat by means of a spring, a projecting member protruding into the first pressure chamber through the through hole provided for the valve element coaxially with the valve element so that the valve element is titlted to form a passage between the valve element and the resilient member by engagement of the piston section of a small diameter of the stepped piston with the projecting member while the stepped piston is at a return position, and the valve element including a passage formed therein through which the first pressure chamber communicates with the reservoir via the internal hole formed in the valve seat and an relief valve for maintaining the passage closed until the effective pressure within the first pressure chamber reaches a predetermined value.

    • PROBLEM TO BE SOLVED: To provide a multi-functional folding bed structure in which light weight pipe frames are linked with each other by hinges or the like in folding state and which has an integrated structure capable of being carried in compactly folded state. SOLUTION: The folding bed structure comprises four continuous supporting faces of which the upper part is composed of the frame structure made of light weight pipes and linked by hinges in freely opening and shutting state or in freely adjustable angles that is covered by a sheet, and which can hold a human body when spread horizontally. It also comprises a front leg, which is capable of folding backward, at the front lower portion of the waist portion supporting face for supporting the upper supporting face, and a rear leg arranged at the waist portion supporting face right and left, which is capable of sliding forward and backward and capable of folding forward at the end of the axis. And a part of the series of the tent for supporting the human body is comprised of a bag for storing by folding tent cloth or tent stretching rods, and the part of the outer periphery of the frame composing the human body supporting face is equipped with a supporting portion for receiving and fixing the stretching rods for stretching the tent cloth or the sheet cloth of a canopy shape.
