Abstract: A tool made of powdered metal, such as a modified T15 HSS in powdered form, and having a multi-lobular end profile for punching multi-lobular recesses into workpieces, such as into the heads of fasteners. The tool is homogenous and contains only carbides which are relatively small, such as in the 1-4 micron range. Also provided is a method of fabricating such a tool. The method requires that a powdered metal bar is cut and then the cut piece is worked to provide the multi-lobular tool. The final part is theoretically 100% dense, as opposed to being only 95-98% dense as in metal injection molded parts. In use, the final part, due to how it is fabricated, has increased column strength and increased impact resistance.

Abstract: An actuator displacement servo-control for aircraft flight controls is assisted by a hydraulic circuit, configured to deliver a hydraulic failure indication. The servo-control is generated from an actuator position indication and a position set-point indication computed by a computation unit. An alarm phase is opened on detection of a servo-control operating error and is kept open as long as the error is present. During the alarm phase it is determined whether the actuator is in blocked or divergent states. If blocked, it is determined whether the duration of the alarm phase exceeds a value Tconf2; If divergent, it is determined whether the duration of the alarm phase exceeds a value Tconf1. When blocked and the duration of the alarm phase does not exceed Tconf2, it is determined whether the hydraulic circuit indicates a hydraulic failure.

Abstract: An electromagnetic operation-type automatic pressure-adjusting valve outputting an air pressure corresponding to an amount of electric power is connected in an air flow path connecting a pressure chamber of a single-acting main cylinder and an air source.

When a target position of a movement of the piston is inputted to the controller, the controller is operated to move the piston toward the target position and to stop the piston at the position by means of controlling the amount of electric power for the automatic pressure-adjusting valve so that an air pressure corresponding to the target position is outputted.
