  • Optical-electric composite cable and method for manufacturing the same
    Patent number: 11460653
    Abstract: An optical-electric composite cable includes a cable unit, at least one metal wire, and a sheath. The cable unit includes at least one optical fiber and a twisted pair wire twisted with the at least one optical fiber. The at least one metal wire is disposed around the cable unit. The sheath surrounds the cable unit and the at least one metal wire.

  • OPTICAL MODULE AND OPTICAL CONNECTOR CABLE
    Publication number: 20220082768
    Abstract: An optical module includes a substrate, an optical element, and a lens module. The substrate has a first surface and a second surface facing each other. The optical element is mounted on the substrate. The lens module has a lens configured to be optically coupled to the optical element and optically couples an optical fiber and the optical element to each other via the lens. The substrate is provided with a cavity recessed from the first surface toward the second surface to have a bottom portion, and at least a part of the lens module is housed inside the cavity.

  • Tool monitoring system
    Patent number: 4918616
    Abstract: A tool monitoring system for detecting a tool failure of a tool employed in a tool machine, comprising artificial signal generating unit for generating a predetermined artificial tool failure signal simulating the acoustic emission signal obtained in an actual failure of the tool, acoustic emission transducing unit adapted to be mounted on the tool machine near the tool and driven by the artificial signal generating unit for applying the artificial tool failure signal to the tool machine, acoustic emission sensing unit mounted on the tool machine near the tool so as to receive, in a setting mode of the system where the transducing unit is mounted on the machine, the applied artificial tool failure signal from the acoustic emission transducing unit through the tool machine and, in a monitoring mode of the system where the tool is operated, an acoustic emission from the tool, and signal processing unit for analyzing an output signal generated from the acoustic emission sensing unit to detect the tool failure of
