Abstract: A disc box structure including a box body and a cover body pivotally connected with one side of the box body. An annular stepped projection is formed in the box body. The center of the annular projection is disposed with two opposite lifted engaging members. The lower ends of the engaging members are connected with the bottom face of the box body, while the upper ends of the engaging members are disposed with substantially semicircular opposite fitting ribs. An engaging projection is formed on an upper end of a middle section of the outer edge of each fitting rib. The inner edges of the opposite fitting ribs have several inward extending resilient bridge ribs which commonly connect with a pressing member, whereby-the engaging members have better structural strength and are protected from breaking due to shearing force of the disc. When it is desired to take out the disc, a user only needs to depress the pressing member between the engaging members to easily take out the disc.

Abstract: A structure is provided which is used for a rectangularly arrayed miniature light bulb series. The structure includes a first controller (3) which regulates and controls the current in a first light bulb string (1). A second controller (4) regulates and controls the current in a second light bulb string (2). The first and second light bulb strings (1) and (2) are joined in series by a first connecting conductive wire (5) and the second controller is in electrical communication with the first light bulb string (1) through a second connecting conductive wire (6). In this manner, light bulbs in light strings (1) and (2) may be coordinated with each other.

Abstract: The present invention relates to a waterproof electric plug with fuses that comprises a housing, a fuse holder, a fuse cover, two plug blades, two tubular fuses, and power lines. When the cover and the holder are inserted into the housing, the complicated structure that is formed will prevent any water or liquid from entering into the housing and the holder. The cover can be pushed to expose an opening in the housing through which the tubular fuses can be replaced.

Abstract: A data entry system (100, 100') has an ergonomic base (102, 102') including upper surface controls (104, 104') which generate a first set of electrical signals, and side surface controls (106, 106') which generate a second set of electrical signals when operated independently. A third set of electrical signals are generated when the side surface controls (106, 106') are operated in combination with the upper surface controls (104, 104'). Data entry system (100, 100') further includes mode selection controls (108) for establishing the first, second and third sets of electrical signals as device control signals responsive to a first mode being selected and respective sets of alphanumeric and keyboard control signals responsive to a second mode being selected.

Abstract: A portable smoke dispersing device includes a cylindrical body containing a motor fixed with a fan for producing a strong wind, and a jet nozzle for spraying minute water drops mixed in the strong wind to flow out of the body into dense smoke in a fire site so as to disperse dense smoke out of a room, a house, etc. Further, a power source and a water tank are attached with the body, and an illuminating lamp and laser sight are also provided for searching into dense smoke for people trapped in a fire to lead them to escape out.

Abstract: A touch-to-action structure of a key signal comprises a lower thin film circuit board, an upper thin film circuit board and a spacer. Wires and a plurality of electric connections are formed on the upper surface of the lower thin film circuit board. The upper thin film circuit board are arranged above the lower thin film circuit board, Wires and a plurality of electric connections are formed on the lower surface of the upper thin film circuit board. The spacer is arranged between the upper and lower thin film circuit boards, the spacer being installed with a plurality of vent holes correspondent to the electric connections of the upper and lower thin film circuit boards. At least one vent hole is installed in each outer rim of the electric connections of the upper in film circuit board and the lower thin film circuit board for venting air. As the key is clicked continuously and rapidly, the air still can effectively vented and sucked so that the touch-to-action hat still can operate normally.

Abstract: Disclosed is a split-lens for grating wheel comprising a disk body and a ring-lens around the peripheral of the disk body wherein said ring-lens comprises alternately-arranged opaque parts and transparent parts, and transparent parts forms the convex lens portion for said ring-lens. The opaque parts are arranged in radial direction on peripheral of the disk body and with equi-angle. By this configuration, the inference problem can be solved and the resolution can be enhanced.

Abstract: A barrette consists of a decorative elongate chain-shaped frame and a decorative elongate strip inserting up and down through decorative holes continually provided in the frame and resting on an upper or lower surface of contact walls separating each two decorative holes of the frame. The frame and the strip may have the same length and width but different colors from each other.

Abstract: A case-in device of an adhesive bookbinder includes a base inside which two shafts are rotatably mounted to be driven by a motor to rotate in opposite directions. A binding platform is pivotally mounted to the base and has two clamping plates movably supported thereon. The platform has two elongated slots and two guide rails corresponding to the slots. Each of the guide rails has two slides slidably mounted thereon and each corresponding to and connected through the respective slot to each of the clamping plates. Each of the slides has a roller rotatably supported thereon. The shafts have lever arms fixed thereon and the arms are sized to be engageable with the rollers and thus driving the clamping plates toward each other to clamp and the apply a force to a book disposed therebetween for adhesively securing the book cover to the book.

Abstract: A method and a device for treating waste printed circuit boards with molten tin include process of throwing printed circuit boards into a molten tin bath in treating furnace, letting the boards proceed crashing, stirring and carbonizing treatment for separating copper foil, thermosetting plastic and glass fiber. Then these three kinds of materials are respectively separated from each other by taking advantage of their different specific gravity and collected in separate tanks to recover copper and other metals from the waste printed circuit boards.

Abstract: An electronic device cooling arrangement includes a heat sink bonded to a substrate above a chip on the substrate, the heat sink having a mounting section bonded to the substrate, a face panel section suspended above the chip and defining a tapered center through hole, and a supporting frame section connected between the face panel section and the mounting section, and a tapered heat conductive block mounted in the tapered center through hole and bonded to the chip for quick dissipation of heat from the chip.

Abstract: A collapsing device for a stroller is provided, including a framework consisting of two front feet, two rear feet, a lying frame, an extended frame and an inverted U-shaped handle pivotally combined with the front and rear feet. When a pusher unit fixed on the handle is pressed, the extended frame supporting a canopy is swung down to a collapsed position to lie on the lying frame. Then, the handle is swung down, with two connecters functioning as pivots for the handle to permit the handle to disengage from the front feet in moving to the collapsed position, responsive to a contact member of each connecter respectively separating from upper ends of the two front feet.

Abstract: A fountain applicator handle includes a body having a side part extending laterally therefrom the body, the side part communicating with the body. A neck section is defined in the first passage of the body and has a tapered shoulder defined in the first passage, the tapered shoulder located near the front end of the body to which a roller is attached. A control device has a bar extending radially from the first end thereof and an insert extends from the bar. An aperture is defined between the bar and the insert. The control device is movably inserted into the body and the insert is movably inserted into the side part. The bar normally close the second passage. A block has a tapered end thereof engaged with the tapered shoulder and is fixedly connected to the second end of the control device.
