The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve, which is a pressure control valve, thereby generating damping force. By thrust from a solenoid actuator, the valve-opening pressure of the pilot valve is controlled, and the pressure in a pilot chamber is also controlled to control the valve-opening pressure of the main valve. When there is a failure, a valve body of the pilot valve is retracted to abut against a fail-safe disk by spring force of a valve spring. Thus, damping force is generated by the fail-safe disk at the downstream side of the pilot valve, and the valve-opening pressure of the main valve is also controlled by the fail-safe disk to obtain an appropriate damping force.

A balloon or self expandable endoprosthesis formed of a single or multiple joined stent sections. Each section has a node and strut structure extending throughout in order to uncouple expansion forces of the stent to hold a blood vessel outward from crush forces that resist the formation of an oval shape during a crush deformation. The hinge can bend in the direction of a uniformly curved surface of the stent but not in the radial direction. The strut can bend in the radial direction but not in the uniformly curved surface of the stent. The widths, lengths, and radial dimensions of the hinges and struts provide a balloon-expandable hinge stent that is non-crushable. For a self-expandable stent the hinge and strut dimensions provide expansion forces that are controlled independently from crush forces. Expansion properties are determined by the hinge dimensions and crush properties are determined independently by the strut dimensions.

A windage brake for a fan descender comprises a rotatable spool connected by drive belts to a fan comprising a radial flow air impeller. A line is wound helically upon the spool. A user of the fan descender puts on a harness (not shown) at the free end of the line and jumps from an elevated position. The line is thereby drawn off the spool and rotates it. The rotating spool drives the fan and also winds a power spring formed by a resilient strip. The windage of the fan regulates the descent of the jumper, the fan being accelerated to a speed at which the braking force is such that the jumper descends at a rate safe for landing on the ground. When the jumper is on the ground, he removes the harness and releases the free end of the line. The line is then automatically retrieved by the power spring and rewound on the spool.
