  • Patent number: 10840763
    Abstract: An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.

  • Patent number: 9787162
    Abstract: The vibration power generator includes: a plurality of permanent magnets (1, 2) integrated together to have given inter-magnet gaps under a state in which the same poles of the permanent magnets are opposed to each other; and a plurality of coils (3, 4) arranged on respective outer peripheries of the plurality of permanent magnets so as to have a distance from the plurality of permanent magnets, and is configured to generate an electric power through relative movement of the plurality of permanent magnets and the plurality of coils. A relationship between a length of the opposed coils and a length of the permanent magnet is set so that the length of the coils is larger than the length of the permanent magnet and equal to or smaller than a sum of the length of the permanent magnet and a length of the inter-magnet gap.

  • Patent number: 8881355
    Abstract: This repair device includes a casing, a slide shaft slidably arranged with respect to the casing, a turn table rotatably arranged with respect to the slide shaft, a cutting mechanism installed on the turn table and including a cutting tool, and an advancing and retracting mechanism that displaces a radius of rotation of the cutting mechanism with respect to rotations of the turn table forward and backward. In a state where the casing is centered and positioned with respect to the pipe, the turn table is rotationally displaced while the slide shaft slides in an axial direction, and the advancing and retracting mechanism displaces the cutting mechanism forward and backward. Accordingly, the cutting tool helically turns along an inner peripheral shape of the pipe to cut an inner periphery of the pipe.
