Abstract: Device for making and/or breaking a current including a pair of permanent contacts (3, 4), at least one of the contacts (3, 4) being movable. At least one permanent contact (3, 4) including a main portion (3.1, 4.1) having a free end and an end protection portion (3.2, 4.2) secured to the free end of the main portion (3.1, 4.1), designed to be in mechanical and electrical contact with the other permanent contact (4, 3) only during an operation for opening or closing the pair. The end protection portion (3.2, 4.2) is made of a single transition metal having a melting temperature that is strictly higher than that of the main portion (3.1, 4.1) to which it is secured, or of an oxide or carbide of such a metal, or even of zinc oxide. For application in particular to high- or medium-voltage circuit breakers.

Abstract: A method for fabricating an interconnect function array includes forming a first plurality of conductive lines on a substrate, forming an insulator layer over the first plurality of conductive lines and the substrate, removing portions of the insulator layer to define cavities in the insulator layer that expose portions of the substrate and the first plurality of conductive lines, wherein the removal of the portions of the insulator layer results in a substantially random arrangement of cavities exposing portions of the substrate and the first plurality of conductive lines, depositing a conductive material in the cavities, and forming a second plurality of conductive lines on portions of the conductive material in the cavities and the insulator layer.

Abstract: A prime mover control system is provided that can prevent magnification of power fluctuation, included in a feedback signal, that occurs between a generator and a power system, and that enables stable operation of the prime mover to continue, without disturbing the power system.

Abstract: Provided is an apparatus for assembling a camera module comprising a support frame that is formed in a rectangular shape and has a jig horizontally connected to an upper end thereof; a plurality of stages that are vertically stacked and installed in the support frame and adjust a printed circuit board (PCB) in three-axis directions; a board holder that is formed to extend from one end of the uppermost stage and has the PCB mounted on the extending end thereof; and a jig assembly that is disposed on an opening of the jig and has a barrel-integrated housing mounted on the central portion thereof.

Abstract: A miniature hydro-power generation system may include a hydro-generator, a control circuit and an energy storage device. A flow of liquid may be used to rotate the hydro-generator to generate electric power. The control circuit may switch the electric power to charge the energy storage device and/or to supply the electric power to an electrical load. The control circuit may also selectively switch the energy storage device to supply electric power to the electrical load. Further, the control circuit may disable both the hydro-generator and the energy storage device from supplying electric power to the load.

Abstract: A decking assembly having a first deck section with a male leg and a second deck positioned adjacent to and in overlapping relationship to the first deck section. The second deck section has a female leg overlying the male leg of the first deck section. The male leg and the female leg have a triangular tab formed therethrough such that the triangular tab extends outwardly on one side of the female leg so as to secure the edges of the sections together in secure relationship. A plurality of triangular tabs are formed in spaced relationship to each other.

Abstract: A numerical control (NC) processor with an onboard grinding unit is disclosed in which a workpiece is first cut in a preselected contour with a Y-axis cutting tool, and then subjected to honing operation intact whereby both the cutting and honing operations can be performed with just a single processor with high-speed, high-acceleration. With the NC processor, the Y-axis cutting tool is mounted on a sliding base above an X-axis table in a way allowed to move back and forth in a Y-axis direction, while a grinding unit is installed in close proximity to the sliding base. A slider moves back and forth in synchronized relation with rotation of a work spindle to first let the Y-axis cutting tool cut the workpiece into a preselected contour, and then cause a buffing material of the grinding unit to grind a work surface of the workpiece into a high-quality surface finish in conformity with a programmed contour while the workpiece remains held intact in a chucking device.

Abstract: The invention relates to a method of producing an electronic unit of a radio system and an electronic unit of a radio system. The electronic unit comprises a mechanical part, a circuit board attached to the mechanical part and an electronic component connected to the circuit board. The method comprises mounting (1702) the electronic component in a cavity provided for the electronic component in the mechanical part; placing (1704) the circuit board on the electronic component and the mechanical part; connecting (1706) the electronic component and the circuit board together using electric coupling members for aligning them with respect to each other and for forming an electrical connection between electric connecting means of the circuit board and electric connecting means of the electronic component; and attaching (1708) the electronic component and the circuit board to each other and to the mechanical part automatically so that the electronic component will be in contact with the mechanical part.

Abstract: A micro-machining center, in the form of an automatic screw machine, utilizes an array of tools and machining support mechanisms removably mounted on a carriage movable parallel to a first axis, and a spindle/collet mechanism movable parallel to a second axis, with machining and manipulating operations being conducted at the intersection of the two axes in a common plane. A microprocessor control system having multiaxis command capability precisely drives the carriage and spindle/collet mechanisms separately or concurrently to perform a sequence of supported machining functions for fabrication of a given part from stock. With this arrangement of microprocessor, tools and spindle/collet mechanism commands for manufacture of a part can readily be generated, verified, used and retained in storage for later use.

Abstract: A machine tool having a gate-type construction and provided with a tool magazine (11). The tool magazine (11) is mounted between a pair of support portions (3a) of a gate-shaped column (3) and above a work support table (2). The tool magazine (11) is composed of a plurality of tool holders (16) each holding a tool (17), and a driving device (18) for moving the tool holders (16) back and forth. This arrangement permits an efficient use of the working space on the work support table (2), and makes it possible to reduce the sizes of the support table (2) and a bed (1).

Abstract: A tool holder which holds a plurality of tools is mounted on at least one station of the tool turret on a chucker lathe. The fact that a plurality of tools is mounted at one tool station enables a plurality of machining operation to be performed on a work piece without rotating the tool turret and thus provides a substantial saving in machining time. It also provides increased accuracy due to elimination of indexing errors, and also saves setup time because the tools can stay in the tool holder when it is removed from the tool turret to be used on future jobs.

Abstract: Method and apparatus for the briquetting of metal swarf, pellets and powders on roller presses having briquetting rollers which are provided with moulding depressions on their cylindrical surfaces by which a briquette extrusion is formed having alternating briquette mouldings extending from one or other side of the extrusion and arranged in a chequerred pattern, each briquette moulding having a plane face on the opposite side of the extrusion. The extrusion is separated into individual briquettes by a surface pressure applied to the extrusion substantially at right angles to the plane of the extrusion.
