Abstract: A fluid-transferring expander, wherein a tube is disposed through a bladder structure, an expansion space is formed between the tube and the bladder structure, the tube is continuously extrudedly formed, the tube is formed with a first passage connected with a first fluid source and a second passage connected with a second fluid source and outside therein, and the tube is further formed with a through hole communicating with the expansion space and the first passage.

Abstract: An oil suction device is provided, including a main body and a sleeve member. A front end of the main body has a flow hole, an interior of the main body has a receiving space, one of two ends of a piston member is disposed in the receiving space and movable relative to the main body to allow a fluid to flow into or out of the receiving space through the flow hole, and the main body is light-penetrable. The sleeve member covers the main body, the sleeve member has at least one hollow-out portion formed radially, and the sleeve member and the main body are in different colors.

Abstract: A semiconductor device with the metal fuse is provided. The metal fuse connects an electronic component (e.g., a transistor) and a existing dummy feature which is grounded. The protection of the metal fuse can be designed to start at the beginning of the metallization formation processes. The grounded dummy feature provides a path for the plasma charging to the ground during the entire back end of the line process. The metal fuse is a process level protection as opposed to the diode, which is a circuit level protection. As a process level protection, the metal fuse protects subsequently-formed circuitry. In addition, no additional active area is required for the metal fuse in the chip other than internal dummy patterns that are already implemented.

Abstract: A pumping unit is operable between sucking and discharging states. The main body has a sucking channel, a discharging channel and at least one blocking mechanism. The sucking channel communicates with outside and an interior of the pumping unit, the discharging channel communicates with a receiving space of a receiving unit and the interior of the pumping unit, and one said blocking mechanism is arranged within the sucking channel to block the sucking channel selectively. Wherein, when the pumping unit is in the sucking state, the blocking mechanism unblocks the sucking channel, and the fluid enters the interior of the pumping unit; when the pumping unit is in the discharging state, the blocking mechanism blocks the sucking channel, and the fluid enters the receiving space. A pumping device is further provided for sucking a fluid from the receiving space and discharging the fluid to outside.

Abstract: A height-adjustable cart is provided, including: a cart frame, having two first retractable rods which are disposed diagonally and two second retractable rods which are disposed diagonally, each of the first and second retractable rods having an upper rod and a lower rod which is retractably connected with the upper rod; two resilient engaging members, resiliently releasably positioning the upper rod and the lower rod of the two first retractable rods, respectively; two positioning members, removably connecting the upper rod and the lower rod of the two second retractable rods, respectively; at least one tray, connected with the first retractable rods and the second retractable rods.

Abstract: An injection device for diesel exhaust fluid includes a cylinder, a stopper, and an air tube. The cylinder encloses a receiving space. The cylinder has an opening at the bottom end. The stopper is pipe-shaped and has a stopping portion and a top portion at two opposite ends thereof. The stopper is arranged in the receiving space and is movable along the longitudinal direction of the cylinder. the stopping portion selectively plugs the opening of the cylinder so that fluid in the receiving space is unable to flow out via the opening. The air tube is inserted through the stopper and the opening of the cylinder to communicate with exterior. The air tube is positioned to the cylinder near the opening so that the air tube may not move with the stopper.
