Abstract: An antioxidant conductive thermal paste and a method of manufacturing the same are provided. The antioxidant conductive thermal paste includes a reactive monomer, a thermosetting resin, a polymerization inhibitor, an electrically conductive filler, and a thixotropic agent. The method consists of the steps of mixing a reactive monomer, a thermosetting resin, and a polymerization inhibitor evenly to get a first polymer mixture, and adding an electrically conductive filler and a thixotropic agent into the first polymer mixture in turn and blending the mixture evenly to obtain an antioxidant conductive thermal paste with good adherence, high electrical conductivity, high thermal conductivity, improved thermal-mechanical fatigue resistance or mechanical fatigue resistance.

Abstract: A cylinder includes a cylinder body assembly, a cylinder rod assembly, and a piston assembly. The cylinder body assembly includes a cylinder body. The cylinder body defines a receiving chamber. The cylinder rod assembly includes a rod fixed with the cylinder body. The rod includes an inclined resisting surface. The piston assembly includes a piston, a piston rod, and one or more resisting member. The piston is slidably received in the receiving chamber and sleeved on the rod. The piston rod protrudes from the piston and extending out from the receiving chamber. The piston rod is sleeved on the rod, and defines a through hole. The resisting member is movably mounted in the through hole. The piston and the piston rod slide relative to the rod, which enable the resisting surface to resist the resisting member to be partially exposed from the through hole.

Abstract: A rotating air cylinder is disclosed. The rotating air cylinder, comprises a first master cylinder comprising a first cylinder block, a first sealing assembly assembled in one distal end of the first cylinder block; a cylinder shaft partially received in the first cylinder block; a first piston assembly movably sleeving on the cylinder shaft, wherein the first piston assembly moves longitudinally within the first cylinder block, and rotates relative to the cylinder shaft; a second master cylinder positioned coaxial with the first master cylinder comprising a second cylinder block received in another part of the cylinder shaft; a second sealing assembly assembled in the second cylinder block; a second piston assembly received in the second cylinder block, non-rotatably and slidably connected with the cylinder shaft, wherein the second piston assembly moves longitudinally in the second cylinder block and rotates relative to an axis of the second cylinder block.

Abstract: A clamping cylinder is disclosed. The cylinder includes a cylinder block defining a receiving chamber and two vents communicating with the receiving chamber, the cylinder block further defining a through hole communicating with the receiving chamber at a side; a piston slidably mounted in the receiving chamber and defining a through groove corresponding to the through hole, the piston further comprising a resisting surface; and a pushrod assembly comprising a push block movably mounted in the through hole, and a resilient member mounted in the through groove, the resilient member is connected to the push block; wherein the resilient member is adapted to pull the push block towards the piston, and the resisting surface is configured to resist the push block so that the push block moves along the through hole when the piston slides along the receiving chamber.
