A method of creating a feature on a needle. The method comprising the steps of providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter; gripping a distal portion of the needle about the outer diameter; gripping a proximal portion of the needle about an outer diameter; and applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.

Drawn polymer fibers have internal channels running, at least partially, through the length of the fibers. These fibers may be configured to for use as thermal isolators that can thermally isolate material at the central core of the fiber from the outside environment. In such instances, the channels may be used as insulating channels and/or a heating or cooling fluid can be pumped through the channels to maintain the temperature of the material at the inner core. As another application, the fibers may be used as recuperative, regenerative, parallel-flow, counter-flow, cross-flow or condenser/evaporator heat exchangers. In this case, the channels may be used to direct fluid flow. The fiber may allow for the exchange of heat between fluids in the channels.

A robot has a body, a hydraulic control system physically coupled to the body, and a hydraulically-actuated component physically coupled to the body. The hydraulically-actuated component is hydraulically coupled to the hydraulic control system by a hydraulic hose. The hydraulic hose has a length, at least a portion of which extends from a first end to a second end, and a diameter, wherein the diameter of the hydraulic hose at both the first end and the second end is a first diameter, and wherein the at least a portion of the length includes a tapered section in which the diameter of the hydraulic hose decreases, continuously and monotonically, to a second diameter, the second diameter being less than the first diameter. The body includes a restricted region through which the hydraulic hose passes in traversing a path between the hydraulic control system and the hydraulically-actuated component.

A method for manufacturing a thermoplastic container may include locally heating a middle zone of a thermoplastic tube; gripping the tube on either side by using retaining members; pulling the tube apart, causing a middle zone to narrow; pushing the inner wall of the middle zone against each other to obtain a closure; and cutting through the closed-off middle zone to obtain two separate tubular parts. Further is provided a system for pulling apart a tube, the system may include a first retaining member which is provided for insertion into the first zone via the first end and a second retaining member provided for insertion into the second zone via the second end, each retaining member being adjustable between a first position in which the retaining member fits inside the tube and a second position in which, in use, the retaining member exerts a pressure on the inner wall of the tube.

Provided is a mesh-patterned resin molded product (10) used for encasing and protecting a hollow piping member provided in a vehicle or a small ship. The mesh-patterned resin molded product (10), in a case of an ordinary state where no load is applied to the mesh-patterned resin molded product (10), includes a plurality of first resin wired portions (11) that extend parallel to each other, and a plurality of second resin wired portions (12) that extend parallel to each other in a direction respectively intersecting the first resin wired portions (11). Each of the first resin wired portions (11) and each of the second resin wired portions (12) are joined to each other on a joint portion (13) positioned at a mutual intersection portion. At the intersection portion, a direction passing through both axial centers of the first resin wired portion (11) and the second resin wired portion (12) and being orthogonal to both the axial centers is set as an orthographic projection direction P. When the first resin wired portion (11) and the second resin wired portion (12) are viewed in the orthographic projection direction P, a second surface area that is a surface area of the joint portion (13) between the first resin wired portion (11) and the second resin wired portion (12) is smaller than a first surface area that is an overlapping surface area between the first resin wired portion (11) and the second resin wired portion (12). The plurality of first resin wired portions (11) and the plurality of second resin wired portions (12) are formed of a material including a thermoplastic resin.
