Abstract: An amorphous Si (silicon)/Au (gold) eutectic wafer bonding structure is fabricated. An amorphous Si obtained through coating or growth contacts with Au for bonding. The bonding layer is a Si/Au eutectic layer. Si is prevented from being precipitated. The bonding structure has a fast reaction ratio and a uniformed reaction. Thus, an electrical device has an improved electricity and reliability.

Abstract: A wall-mount rack includes at least two vertical posts, at least two hangers, and at least one container. Each of the vertical posts is provided on two lateral sides with one longitudinal row of holes each. The hangers are hooked to two corresponding holes at the same level on two opposite inner lateral sides of the two vertical posts. The container is hung on the two hangers and thereby stably mounted on and between the two vertical posts. The container may be a box-type container to define a receiving space therein.

Abstract: A structure of an optical switch makes the optical switch capable of receiving broadband signals. And the manufacturing procedure is simplified.

Abstract: A sun-tracking apparatus has a photo sensor. The apparatus can precisely track the sun. The apparatus uses two tracking modes for different conditions and weathers. By doing so, a maximum power efficiency is obtained.

Abstract: A multi-stage lens driving device comprises a lens holder, a lens mounted on the lens holder, a carriage carrying the lens holder in a movable manner, at least one magnet coupled to the lens holder, at least one coil disposed on the carriage and corresponding to the magnet, and at least one yoke disposed at a predefined position of the carriage. Through the magnetic field produced by the magnet and the current action in the coil, the force generated thereof can push the lens holder to move toward a desired position, thereby achieving the effect of focusing or zooming. In addition, through the attraction between the yoke and the magnet on the lens holder, the lens holder may be secured to the predefined position. That is, the lens is firmly secured even when the coil current is shut off, thereby achieving the goal of saving power consumption.

Abstract: A network camera holder includes an universal coupling for fixing a network camera and a clinch. The clinch is configured to hook a thin frame and, also, can reverse outward on a pivot in order to grip a thicker frame. The clinch can also be spread out to place the holder directly on a flat surface.

Abstract: A stepper including one short post extending downwardly from a toe end of each of two pedals and a sleeve being provided on a tail end of each short post. Both pedals being respectively mounted to a front lateral lever located on a bottom of a base. Both ends of the lever are capped. Both pedals alternatively swinging up and down with the lever as the axis allowing a wider swing angle for both pedals to effectively reduce the height of the base subject to force.

Abstract: A control device used for a computer motherboard on which a plurality of interface cards is inserted, is composed of an L-shape notch which is opened at a corner or a long strip of notch which is opened at a side edge, of a circuit motherboard positioned in an interior of a computer casing of height of 2U or 1U; a riser card, which is inserted vertically into a preset slot of the circuit motherboard; and an interface short card or an interface long card, which can be fitted into the L-shape notch or the long strip of notch, wherein conduction pins of the interface long, short cards can be inserted into a transversal slot of the riser card, and the interface short card or the interface long card approaches to a same horizontal level as the circuit motherboard, such that the riser card can be added with more slots for insertion of more interface long cards or interface short cards.

Abstract: A toilet tank accessory rack has a fixing element and a holding element. The fixing element is assembled on a wall near a toilet tank of a toilet, and forms first assembling portions thereon. The holding element forms second assembling portions for corresponding to and locking with the first assembling portion. At least a storing chamber is provided on a side of the holding element for storing articles, such as shampoo, washing foam, books and magazines, where a user may conveniently fetch during defecating or washing.

Abstract: A supporting bracket is designed to connect to a wall-mount rack by inserting hooks provided at a rear end of the bracket into holes provided on a front side of a vertical post of the wall-mount rack. The supporting bracket includes two parallelly spaced side wall portions, on top edges of which retaining slots are formed to enable the support of two shelves at two opposite lateral sides of the bracket. Two rails may be connected to two sides of the bracket for supporting a drawer-type container. A hanger may be connected to a lower side of the bracket to support a crossbar for holding suit hangers. The supporting bracket is therefore a multipurpose and highly efficient supporting member very practical for use on the wall-mount rack for supporting different types of holding members.

Abstract: An auto-focus lens module that uses electromagnetic force as well as spring force as driving force to drive the lens for auto-focusing is formed by a rectangular base, two copper plates, an insulation spacer, four magnets, a lens holder, a lens, a coiled spring, a coil, and a rectangular top cover. The lens holder, the lens and the coil form a lens set that moves synchronously. The coiled spring is between the coil and the lens and is elastically supporting between a circular slot of the lens holder and the top cover while the four magnets are respectively located outside the coil symmetrically and equidistantly, on four corners of the rectangular base so that the structure and volume of the lens module are simplified and minimized. Moreover, the distance between the coil and the magnets is shortened so that the electromagnetic force therebetween is increased. Furthermore, the diameter of the coiled spring is reduced for improving stability of the spring force.

Abstract: A server wherein an interior of which is connected with five expansion boards is composed of a server at a height of 1U, an interior of which is fixed with a circuit motherboard on which is welded with expansion slots; a first riser card which is inserted into the first expansion slot; a first expansion board which is inserted into a transversal slot of the first riser card; a second riser card which is inserted into the second expansion slot; a second expansion board which is inserted into a transversal slot of the second riser card; a third riser card which is inserted into the third expansion slot; a third expansion board which is inserted into a transversal slot of the third riser card; a fourth riser card which is inserted into the fourth expansion slot; a fourth expansion board which is inserted into a lower slot; and a fifth expansion board which is inserted into an upper slot; such that the circuit motherboard, and five expansion boards are installed in the server.

Abstract: The present invention provides an improved positron radioactive drug radiation shielding device, which achieves savings in space required to store a canister after dismantling the device. Furthermore, a tungsten sleeve is disposed within the canister, and functions in coordination with a syringe. The tungsten sleeve is able to block radioactive radiation released by radioactive drugs contained in the syringe. Moreover, a front cover and a rear cover joined to two sides of the canister enable a hermetically-sealed space to be formed within the canister, which increases the effectiveness of blocking the amount of radiation from the canister, thereby reducing danger to the human body from the radiation.
