  • Patent number: 10562072
    Abstract: A grizzly apparatus includes a plurality of grizzly bars arranged at predetermined intervals in a second direction perpendicular to a first direction which is an extension direction of center axes of the grizzly bars. Each of the plurality of grizzly bars is rotatable in a direction opposite to a direction of rotation of its adjacent grizzly bar so that a slit through which a screening target object passes and a gap through which the screening target object does not pass alternately emerge, between adjacent grizzly bars. The guide includes an outer member forming its outer shape, and has at least one guide surface inclined with respect to the second direction in such a way that the guide surface descends as the guide surface advances in the second direction toward the slit to guide the screening target object having fallen onto the guide to the slit.

  • Publication number: 20040071414
    Abstract: A system is provided for fusion splicing at least one pair and, more typically a plurality of pairs (e.g., 24 pairs), of optical fibers together. The system includes a pair of electrodes and a controller. The optical fibers are positioned between the pair of electrodes. In this regard, the electrodes are capable of passing an electric current therebetween to create an electric arc capable of heating an end of each of the optical fibers. The controller is capable of controlling the electrodes to thereby pass the current therebetween to create the electric arc. Advantageously, the controller is capable of controlling the electrodes to pass an initial current to thereby create and maintain an initial electric arc and thereafter pass a processing current to thereby create and maintain a processing electric arc, where the initial current is higher than the processing current.

  • Patent number: 5371931
    Abstract: Software and hardware such as part feeding and assembling devices constituting a production system are simplified with the use of a plurality of processing and assembly integrated units in which processing and assembling of parts are coupled and integrated in accordance with products to be produced. The necessities for an automatic warehouse and an automated ground vehicle are eliminated by getting rid of futility of mere movements of the parts. A fundamental idea is that a production system is constructed of units in which three sections--a section for processing a raw material, a check functional section and an assembling section--are integrally combined in accordance with the products to be produced. The parts are processed, checked and assembled by single units just in time while targeting molded parts of plastic and pressed parts.

  • Patent number: 4620663
    Abstract: An apparatus for connecting wiring patterns on a wiring board and leads of a parts to be mounted on the wiring board, via the solder provided between the leads and the patterns. The parts-connecting apparatus enables, especially, circuit elements of a high degree of, to be connected automatically with high reliability and accuracy by using solder through the steps of setting the wiring board in a predetermined position while pressing a surface thereof so as to remove the warp from the wiring board, fastening the leads of the part to the wiring patterns by a magnet provided on the lower surface of the wiring board, and heating the solder provided on the portions of the leads which are fastened to the wiring patterns.

  • Patent number: 4571822
    Abstract: A method of and apparatus for inserting coils into slots formed in the stator core of a dynamoelectric machine such as an electric motor, with the stator core having open type slots each of which cooperates with blades of the apparatus for guiding the coil and a stripper for forcing the coil out of the blades. A closed space has a volume sufficient to avoid any disorder of coil wire layers when the coil is received by the closed space. After placing the coils in the closed spaces, the coils are pushed into the respective slots and, as desired, the coils are further compressed until the coil wires assume a non-circular cross-section. By so doing, it is possible to remarkably increase the space factor of each slot.
