The present invention relates to medical vascular catheters adapted to be inserted into a blood vessel from an incision through the skin of a patient for introducing ther devices or fluids for diagnostic or therapeutic purposes, and particularly to an improved distal soft tip or segment attachment with a relatively stiff proximal catheter shaft. A tubular sleeve is bonded through the application of pressure and heat to a distal portion of the catheter shaft and a proximal portion of the distal segment of soft distal tip bridging the attachment junction. In the preferred method, the catheter shaft distal end is aligned with the distal segment or soft tip proximal end and the sleeve is fitted over the attachment junction. A heat shrink tube is fitted over the sleeve and adjoining portions of the catheter shaft and the distal segment or distal soft tip and heat is applied. The shrinkage force of the heat shrink tube over the assembly of the tubular sleeve overlying and bridging the attachment junction and the applied heat melts and force the materials of the tubular sleeve and the catheter shaft and the distal segment or distal soft tip together to fill interstitial spaces of the attachment junction and reduces the outer diameter of the sleeve. The heat shrink tube is removed after the assembly cools and solidifies. Preferably, the catheter shaft distal end and the soft tip or intermediate segment proximal end are each formed with a like plurality of ungular cut sections that are complementary in shape to one another, whereby the ungular cut sections are aligned with and mated together along the attachment junction.

A fiber optic cable has a plug assembly that may be positioned and secured at any desired location along the length of the cable to engage a receptacle disposed within a connector port provided in a wall of a connection terminal. The plug assembly includes a shroud, a coupling nut, a heat shrink tube for sealing the cable and a boot for providing bending strain relief. At least a portion of the cable passes through the connector port for interconnection with optical fibers of a distribution cable or optical equipment. A method for routing a fiber optic cable into a connection terminal includes using a connector port provided in a wall of the terminal, determining a desired length of the cable, positioning and securing a plug assembly at a desired location along the length of the cable, and mating the plug assembly with a receptacle disposed within the connector port.

A waterproofing method is provided for a wire to be arranged in a water susceptible area of a vehicle. An insulating coating layer is removed in a lengthwise intermediate part of the wire to expose a core. A heat shrinkable tube with an inner layer made of a hot-melt waterproofing agent is mounted on the exposed core section and parts of the insulating coating layer adjacent to the exposed core section and heated. As a result, the hot-melt waterproofing agent of the inner layer is melted and infiltrates into clearances between strands of the exposed core section. In addition, negative pressure is introduced into the inside of the insulating coating layer from an end of the wire, thereby sucking the waterproofing agent into the inside of the insulating coating layer to infiltrate the waterproofing agent also between the strands of the core inside the insulating coating layer.

A liquid fuel burner adapted to be inserted into an opening of a supporting base, such as a statue or other art work, includes a container to hold combustible fuel, a tube having one end attached to an opening in the container, a collar assembly secured to the other end of the tube and having a cap closing the end of the tube and a flange part to support the burner in the opening, and a wick extending from the container through the tube and being held within an opening defined in the cap. The cap may include a glass wick holder to support the wick in burning position thereabove. The fuel container may be defined by one or more flexible bladders which are attached to the tube by insulation, tape, heat-shrink tubing, or a wire clamp.

The time period during which a wafer is stabilized to a predetermined temperature by increasing a thermal conductivity of a junction layer for bonding an electrostatic chuck layer and a support together, and the deterioration of the junction layer that is caused by active species generated by plasma is suppressed. Between the electrostatic chuck layer formed by sintering together a chuck electrode made of tungsten and an insulating layer made of alumina and the support, made of aluminum, for supporting the electrostatic chuck layer, the junction layer is provided to bond the electrostatic chuck layer and the support together. The junction layer is formed by impregnating a porous ceramic with a silicone-based adhesive resin. Further, rubber or a heat shrink tube made of a fluoric resin such as PFA is provided as a soft coating member so as to coat a side circumferential surface of the junction layer and the side circumferential surfaces of the electrostatic chuck layer and the support come into a tight contact with the heat shrink tube or rubber.

To decrease cap diameter covering a terminal splice and improve workability and waterproof performance, a stopper is inserted in one opening of a heat shrinkable tube. The heat shrinkable tube is heat-shrunk in this state, then a cap having end an closure is formed. A fluid thermosetting waterproofing agent is injected into the cap from a second opening. A thermal splice, which is formed from welded strands stripped from a plurality of wire terminals, is inserted and immersed in the thermosetting waterproofing agent. Then, the entire cap is heated and heat-shrunk at a predetermined temperature and the thermosetting waterproofing agent is heat-hardened.

The invention provides a six-dimensional force sense sensor for a minimally invasive surgical robot. The six-dimensional force sense sensor comprises two cross-shaped-shaped beam elastic bodies, two baffles and an elastic body substrate, wherein arc I-shaped holes which are orthogonally distributed are formed in the cross-shaped beam elastic bodies respectively, the elastic bodies are installed at the head end and the tail end of the elastic body substrate in a clearance fit mode in the direction of strut beams stretched out of cross-shaped beams, and the elastic bodies are fixed by the two baffles. Four strain gauges are pasted on each of the four strut beams of each elastic body cross-shaped beam and used for measuring corresponding force or force torque, the four strain gauges on each strut beam form an equal-arm full bridge circuit, four signal lines are led from each equal-arm full bridge circuit and bundled into one bundle after being wrapped by a heat shrink tube in a hot shrinkage mode, and then the bundle is led out of a mechanical hand through a mechanical hand hollow metal round rod from space regions among the cross-shaped beam strum beams. The sensor is installed at the position close to an end effector of the minimally invasive surgical mechanical hand and measures six-dimensional force sense components, and the negative influence of the friction of the mechanical hand and an incision on data measured by the sensor is avoided.

A surface tracker includes a tubular marker body having an interior electronic marker and a visual indicator attached to an upper end of the marker body which extends away from the marker body. When deployed, the marker body is mostly underground and the visual indictor extends upwardly from the ground level to provide above-ground visual recognition. The visual indicator may be a plurality of resilient filaments which pass through a hole in a tab portion of the marker body at the upper end thereof, the filaments being folded about the tab portion and secured to the tab portion using a heat-shrink tube. The visual indication, along with the ability to electronically detect the marker, provides a tracker with superior locating capability.

A metal sheathed heater utilizes splice connections that connects ends of a heater cable with ends of a lead wire. Each splice connection has a connector that connects core wires of the lead wires and heater cable together. Heat shrinkable tubing surrounds the connector and ends of the heater cable and lead wires. An adhesive is interposed between the heat shrinkable tubing and heater cable and lead wire ends to bond with the heat shrinkable tubing and complete the splice connection. The metal sheath of the heater can be formed with an enlarged diameter portion to account for the heat shrinkable tubing surrounding the lead wire and heater cable ends.
