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 clamp apparatus includes seat and a stopper. The stopper is force toward the seat by an elastic member, so that the stop and the seat are able to clutch and stop a tube or a multi-way valve. The seat is provided with a detachable holder which clips or presses on the tube or the multi-way valve. Thus, by interchanging the holder with another holder, the clip can fit with sizes of tubes and multi-way valves. Application of the clamp apparatus is expended with minimal accessories.

Abstract: A hammer includes a handle, a head portion, and a striking mechanism. The head portion is connected with the handle and includes a metal strike element and a resilient strike element. A receiving space is defined between the two strike elements. The striking mechanism is located in the receiving space and includes a slide axle and a striking member. The striking member has a through hole for being slidably sleeved onto the slide axle. The striking member is slidable in the receiving space to alternatively strike one end of the head portion. Thereby, inertia striking force is provided by the striking member so that the hammer can be used to strike an object more easily.

Abstract: An oil injector for a vehicle is provided. The oil injector includes a transparent body having a flowing hole formed on a front end of the body. A flexible tube member is connected to the body and corresponds to the flowing hole. A storing space is formed in an internal portion of the body. One end of a piston member is entered into the storing space, and the piston member is movable relative to the body. Therefore, the piston member provides a pushing function in the storing space so that a fluid flows into or out form the body via the tube member, and the transparent body is provided for observing a storing amount of the fluid in the body.

Abstract: A clip includes a pair of operable jaws each of which is provided with a detachable holder. Several holders are also prepared in reserve. The holders have several kinds of shapes and sizes. Thus, by interchanging the holder with one another, the clip can fit with different kinds of tubes and multi-way valves, and with different sizes of openings or orifices. Application of the clip is expended with minimal accessories.

Abstract: An auxiliary device for vehicle maintenance including a pneumatic cylinder and a multi-mode control vale unit at least having a foot vale is provided. One end of a cylinder body and a first end of an axial rod of the pneumatic cylinder are to be coupled to a steering wheel and a brake pedal, respectively. The foot vale is connected between an inlet and outlet portions and selectively permits the inlet and outlet portions to be communicated pneumatically with each other. When the inlet and outlet portions are communicated pneumatically with each other, pressurized air goes into the cylinder body and drives the axial rod moving away from the cylinder body.

Abstract: An oil changing device for a transmission includes a tub body having a receiving space for receiving transmission oil, a main assembly having a base body, a manual set and a backflow valve, the base body mounted to the tub body, the base body having a main channel, a first passage and a backflow passage, the base body configured to connect with one end of an injection tube, another end of the injection tube connected to a transmission, the injection tube communicating with the main channel, the base body having a through hole opened therethrough, the through hole communicating with the main channel, the manual set having a second passage defined therein, the first passage connected between the main channel and the second passage, the backflow valve inserted into the through hole, and the backflow valve selectively closing or unclosing the backflow passage.

Abstract: A data encryption method, adapted to a node computing device in a cloud server system comprises following steps. A primary data is received. A dimension of an encrypted matrix is computed. An encryption length is computed, and data segments matching the encryption length are extracted from the primary data sequentially according to the encryption length. A plurality of encrypted segments is obtained by encrypting the extracted data segments respectively through the encrypted matrix.

Abstract: A drain pan for vehicle axle is adapted for being positioned to a circular margin of a hub. The drain pan includes a front wall, a rear wall, a bottom connecting the front wall and the rear wall therebetween, two lateral walls connecting the front wall and the rear wall therebetween, two cambered walls connecting the bottom and the lateral walls therebetween, and at least one magnetic member. The magnetic member is disposed on an outer surface of the one of the cambered walls. Each cambered wall and the magnetic member contact the circular margin of the hub for positioning the drain pan onto the circular margin by magnetic force. Thereby, the drain pan can be positioned quickly, and the drain pan is able to be utilized on hubs in various sizes.

Abstract: A spray gun includes a controller, an expanding tube, a spray tube, and a connector between the controller and the spray tube. A fluid container communicates with the connector via a fluid tube. An inner tube is disposed in the spray tube and has an end communicating with the fluid tube. The expanding tube is disposed around the spray tube and has a restrict portion formed inside to sleeved around the inner tube. When pulling the trigger to drive gas to enter the connector and the spray tube, fluid in the fluid container is sucked out to be mixed with the gas in the spray tube so that the spray tube swings to spray out. Thereby, the spray tube can swing only in a restricted range instead of swinging irregularly.

Abstract: A clamp apparatus includes seat and a stopper. The stopper is force toward the seat by an elastic member, so that the stop and the seat are able to clutch and stop a tube or a multi-way valve. The seat is provided with a detachable holder which clips or presses on the tube or the multi-way valve. Thus, by interchanging the holder with another holder, the clip can fit with sizes of tubes and multi-way valves. Application of the clamp apparatus is expended with minimal accessories.
