Abstract: A nose bridge strip having a scent-releasing mechanism can be included in a mask structure and includes a main body and at least one scent-releasing element. The main body is in a shape of a strip and can be combined with the scent-releasing element. The scent-releasing element can produce scent molecules capable of reacting with olfactory cells in a nasal cavity such that bioelectric waves are generated and propagate to the brain. The mask structure includes the nose bridge strip and a mask body that can be arranged with the nose bridge strip. When the mask body is worn on a human face, the nose bridge strip can be pressed and deformed compliantly against the nose bridge so that a user wearing the mask structure can smell a pleasant scent while breathing and feel comfortable.

Abstract: An insulated wire capable of changing color when overheated under a current load includes an insulated core, at least one thermochromic strip, and a transparent plastic protective layer. The thermochromic strip is wound and fixed on the peripheral surface of the insulated core. The transparent plastic protective layer clads the peripheral surface of the insulated core and/or the top surface of the thermochromic strip. When the insulated core is overloaded and generates heat, the heat is transmitted to, and thereby changes the color of, the thermochromic strip. The color change is visible through the transparent plastic protective layer and can therefore alert the wire user in real time that the load on the insulated wire should be lowered.

Abstract: A decorating wire capable of showing a hollow spiral strap includes a core wire, a first transparent plastic body, a first strap and a second transparent plastic body. The first transparent plastic body is wrapped around the core wire. The first strap is wound spirally and axially on the first transparent plastic body and maintains a predetermined interval along the first transparent plastic body. The second transparent plastic body is wrapped onto the first transparent plastic body and the first strap. The second transparent plastic body has a thickness from 0.5 mm to 1.5 mm, so that the first strap can provide a light refraction effect due to the thickness of the second transparent plastic body, and show a visual effect of winding the first strap onto the second transparent plastic body. The color and interval of the transparent plastic bodies and straps can be changed for different designs.

Abstract: A color decorating wire includes at least one color wire of a different color and a transparent plastic skin formed on the color wire by an extrusion molding or an injection molding and wrapped completely onto the color wire. The transparent plastic skin includes at least one connecting plate extended outward from a surface of the transparent plastic skin, and each connecting plate is extended axially along the color decorating wire, and the color decorating wire is fixed onto an object by the connecting plate, so that the color decorating wire concurrently provides glittering and color changing effects.

Abstract: The present invention relates to an apparatus for manufacturing wire having an inverted cone-shaped cylinder within a spool, wherein the diameter of the top end of the cylinder is larger than the lower end thereof enabling a tape wound thereon unwound from the spool to go from a lower position to a higher position of the cylinder while the tape being wrapped on the wire due to the centrifugal force of rotation in the wrapping process. This has the benefit of preventing the subsequent turns of the tape from loosening out of the spool, and enables the tape being continuously, evenly, and securely wrapped on the wire in a high speed operation.

Abstract: A color cable and the manufacturing method thereof involves an electrical transmission cable having one or more conductors, one or more color windings uniformly wound around and secured to conductor body by heating, and a transparent plastic covering formed on the winding by injection molding. The color of the winding may be seen from outside through the transparent plastic covering. A multi-colored cable is obtained by changing the color or number of the strands, or by substituting strands or windings of one color for strands or windings of another color during winding.

Abstract: A color ornamental cord device having at least one piece of supporting core material, at least one reinforcing wire respectively embedded in each piece of supporting core material, a color ornamental material surrounding each piece of the at least one piece of supporting cord material, and a transparent plastic cover layer extrusion-molded on the color ornamental material.

Abstract: A color cable and the manufacturing method therefor involves an electrical transmission cable having one or more conductors, one or more color windings uniformly wound around and secured to conductor body by heating, and a transparent plastic covering formed on the winding by injection molding. The color of the winding may be seen from outside through the transparent plastic covering. A multi-colored cable is obtained by changing the color or number of the strands, or by substituting strands or windings of one color for strands or windings of another color during winding. The color(s) of the cable may be for purely decorative purposes, or may depend on electrical specifications and usage so that a user can recognize the specifications or usage from the color of cable.
