Disclosed are: a power transmitting device that can be used to freely control specific objects inside a rotating body, which rotates at high speed, by directly transmitting an external force into the rotating body while the rotation remains unaffected; and a pipe cutting device and a hydraulic chucking device using the power transmitting device. The power transmitting device according to the present invention comprises: at least one linked-movement cylinder which is fitted in such a way that a rod projects to the side of a main body, on the back surface of the rotating body; a push part which is provided towards the main body so as to have at least one pusher projecting towards the rotating body; and a bearing which is coupled so as to perform an axially rotating action and perform an action whereby an axially-oriented load is transmitted, between the pusher and the rod. Such a power transmitting device can be used as a pipe cutting device by fitting a cutting tool that performs a reciprocating movement due to a hydraulic cylinder at the front of the rotating body, and by constructing the hydraulic cylinder and the linked-movement cylinder as a hydraulic closed circuit. Additionally, the invention can also be used as a hydraulic chucking device by constituting a plurality of the hydraulic cylinders of the rotating body, and by fitting jaws to each hydraulic cylinder.

The invention relates to a flat plate vapor chamber and a manufacturing method thereof. The flat plate vapor chamber comprises a packaging chamber, a porous capillary wick, a working medium and a vacuumizing and work medium filling interface, wherein the porous capillary wire and the working medium are positioned inside the packaging chamber; one end of the vacuumizing and work medium filling interface is communicated with the inside of the packaging chamber; and the other end of the vacuumizing and work medium filling interface is positioned outside the packaging chamber and is sealed. The manufacturing method of the flat plate vapor chamber comprises the following steps of: forming the packaging chamber by extruding or casing; forming the porous capillary wick by sintering or knitting; inserting the porous capillary wick into the packaging chamber; placing one end of the vacuumizing and work medium filling interface in the packaging chamber; extruding the packaging chamber by using a cold press die; moving away the cold press die; welding and sealing a front-rear end closing surface of the packaging chamber; vacuumizing the packaging chamber and filling a working medium; and pinching off the vacuumizing and work medium filling interface and welding and sealing the vacuumizing and work medium filling interface. According to the flat plate vapor chamber disclosed by the invention, the defects of limited structure, high manufacturing cost, low reliability, limited heat-radiating capability and the like in a traditional vapor chamber are fully overcome.

A pressure-sensitive sensor includes a hollow tubular member including an elastic insulation, plural electrode wires spaced from one another and held on an inner circumferential surface of the tubular member, and helical ribs formed on at least one of inner and outer circumferential surfaces of the tubular member along a longitudinal direction thereof. The electrode wires are helically arranged along the longitudinal direction. A helical direction of the helical ribs of the tubular member is a same as a helical direction of the helically-arranged electrode wires.
