摘要： There is provided an air-cylinder apparatus for use in a prosthetic limb capable of effectively adjusting the pressure characteristics over a wide range of walking speed. A second chamber 82 defined by a piston 113 is increased in pressure by air confined therein in accordance with the bending motion of the knee. Air is restricted from flowing out of the second chamber 82 by a constant throttle valve 140. In addition, the second chamber 82 is divided into plural chambers 821, 822 in accordance with increase in bending angle of the knee and air is restricted from flowing out of the newly divided chambers 821, 822 by throttle valves corresponding thereto. The division of the second chamber 82 is achieved by mutual engagement between a projection 1140b on the piston side and a recess 1127 on the bottom part of a cylinder body.

摘要： A slider unit having built in a moving-coil linear motor ensuring high propulsion, is kept slim in overall height. A moving-coil assembly is made slim, with high stiffness, and is composed of an iron core of platy-configuration, and at least one set of three-phase armature coils wound around the iron core in the form of flat rectangular configuration in a plane intersecting the sliding direction. Comparatively more coil sides of the armature coils contribute to high propulsion. Like poles on either field magnet are placed in opposition to each other across the air gap, whereby the magnetic attraction is cancelled to reduce the load on the linear motion guide unit.

At both ends of a straight passage 5 of the nut main body 2, a pair of circulation members 8 is provided respectively, in each of which a direction change passage 6 is formed for connecting the straight passage 5 to a loaded rolling-element rolling passage 3. The circulation members 8 in a pair are fit in a pair of recesses 15, respectively, formed in the outer diameter portion of the nut main body 2. The direction change passage 6 of each circulation member 8 has a curve passage 22 which is connected to the loaded rolling-element rolling passage 3. The curve passage 22 is formed in such a way that, when seen in the axial direction of the nut main body 2, the track of the center of each rolling element 7 moving in the curve passage takes the shape of an arc.
