Abstract: The plastic tube cutter comprises: a shell-body; a cutting-unit; and a pressing-arm; wherein the cutting-unit having a semicircular concave-arc end-face at one end is pivotally set in the shell-body; wherein four rolling-wheels corresponding to each other are spacedly set on two sides between the concave-arc end-face and the opening, and the other end of the shell-body has a gripping-arm; wherein the pressing-arm is pivotally set at the bottom of the shell-body and spaced apart from the gripping-arm to face with each other; wherein the four rolling-wheels of the semicircular concave-arc end-face are provided for accommodating a plastic tube body. In addition, a hooking-piece and a rod-body are respectively set on opposite sides of the gripping-arm and the pressing-arm to hook the hooking-piece and the rod-body. Therefore, maintaining the cutting freedom and the flat-smooth cutting, and cutting the high-thickness plastic tube body in a rotation way can be achieved.

Abstract: A injection molding machine includes a power device including a movable plate, a primary motorized cylinder having a primary threaded rod screwed through the movable plate, a secondary motorized cylinder having a secondary threaded rod screwed through the movable plate, a first starter mounted on the primary motorized cylinder and connected with a controller, and a second starter mounted on the secondary motorized cylinder and connected with the controller. The second starter contains a bias factor command and a preset output command. Thus, the normal torque output of the secondary motorized cylinder is close to that of the primary motorized cylinder by control of the bias factor command, and the preset output command limits and prevents the normal torque output of the secondary motorized cylinder from being greater than that of the primary motorized cylinder.

Abstract: An opto-electrical conversion structure includes a substrate, a first semiconductor structure, and a second semiconductor structure. The substrate has a first surface and a second surface opposite to each other. The first surface has a plurality of micro-structures and a plurality of nano-structures. The nano-structures are distributed on the surface of the micro-structures, and have heights of about 500 nm to about 900 nm. The first semiconductor structure is disposed on the first surface of the substrate. The second semiconductor structure is disposed on the second surface of the substrate.

Abstract: An electrochemical machining process is disclosed for forming multiple raised areas having multiple heights in a wall of predrilled holes within a workpiece. Positioned within each hole is an electrode coated with an insulating material in a pattern defining the raised areas to be formed in the wall of each respective hole. An electric current is applied from a power supply to each of the electrodes. A resistor is positioned between the power supply and at least one of the electrodes to vary the voltage passing through the electrode to vary the amount of material removed within that respective hole.
