Abstract: Disclosed are an overhead ribbon cable, a manufacturing method, and a manufacturing system for the overhead ribbon cable. The overhead ribbon cable includes an optical fiber ribbon array (10). The optical fiber ribbon array (10) includes a plurality of optical fiber ribbons (11) arranged in an array. A surface of the optical fiber ribbon array (10) is wrapped sequentially with a water-blocking assembly and an outer protection layer (50). The water-blocking assembly includes a water-blocking sealing layer (20) formed by heating and curing a sealant. The water-blocking sealing layer (20) wraps the surface of the optical fiber ribbon array (10) in an axial direction of the optical fiber ribbon array (10) and fills a gap between two adjacent optical fiber ribbons (11). The overhead ribbon cable has improved splicing efficiency, and is clean and environmentally friendly.

Abstract: A micro-cable, a manufacturing method therefor, and a filling device, which relate to the technical field of micro-cables, the micro-cable being used for transmitting signals. The micro-cable comprises a cable core and an outer sheath covering the peripheral surface of the cable core, wherein the cable core comprises a central strengthening member, a plurality of optical units and a sealant, with the plurality of optical units being twisted around the central strengthening member, and twisting gaps between the plurality of optical units being filled with the sealant. Further provided is a method for manufacturing the micro-cable. The filling device comprises a sealant-injection and stranding mold, a sealant injection valve, a sealant pump, and an air source, wherein the sealant-injection and stranding mold is internally provided with a filling channel and a sealant injection channel.

Abstract: Here disclosed is a composite catalyst for methane cracking and a method of producing the composite catalyst.

Abstract: Disclosed herein are devices, systems, methods and kits for performing immunoassay tests on a sample. The immunoassay devices may be used in conjunction with diagnostic reader systems for obtaining a sensitive read-out of the immunoassay results. The immunoassay devices may be especially suited for the detection of at least a first analyte and a second analyte in a sample. The immunoassay devices and methods may utilize a competitive binding-like assay and a sandwich binding assay to detect analytes in a sample.

Abstract: Disclosed are an electronic component sucking device and an electronic component testing apparatus using the same, the sucking device comprising a suction head having at its extremity an opening arranged to suck an electronic component when a negative pressure is applied thereto; a hold-down center rod having an aperture, a conduit through which passes a gas supplied or discharged through the opening of the suction head, and a hold-down portion at its extremity adapted to be inserted into the interior of the suction head; a coil spring for imparting a biasing force to the suction head and the hold-down center rod; and a link lever interposed between the suction head and the hold-down center rod; wherein when the hold-down center rod is subjected to a force pressing down against the biasing force of the coil spring, the link lever pushes the suction head upward so that the hold-down portion of the hold-down center rod protrudes from the suction head.
