摘要:
A method for forming a tubular member includes preparing a longitudinal Teflon strap, winding the Teflon strap around a longitudinal core to form a tubular prototype having two or more layers, and welding the two or more layers of the Teflon strap together to form the tubular member. The layers of the Teflon strap are preferably arranged at different angles or inclined relative to each other, or arranged at different angles with respect to the longitudinal axis of the core or of the elongate tubular member. The tubular member may further be shaped to various shapes or configurations with such as extending, stretching, expanding, enlarging, or shaping process.

The present invention of a manufacturing process of a Teflon dual-direction extending film filtration nonwoven uses a Teflon, after it is splitted and become a fibrous structure, followed by inter-twisting to become yarn, and use a knitting machine to knit as a Teflon fabric, after raising to damage its knots, apply thermo-heating to laminate and adhere-combine the Teflon dual-direction extending film, a filtration nonwoven is made, roll the filtration nonwoven with two sides treated by raising repeatedly to become a filtration material or as a filter bag, a dust-collecting bag or a conveyor, thus a Teflon fabric has the characteristics of having stably fixed position and can optimize its filtration effectiveness.

The present invention of a manufacturing process of a Teflon dual-direction extending film filtration nonwoven, a dual-direction extending film is film-splitted to become a flock or lint structure, place the processed dual-direction extending film which is in flock or lint structure on the non-processed dual-direction extending film, go through carding process,, after multi-laying, send it to needle-punching machine to needle punch it into a nonwoven of strong structure, then laminate with a layer of Teflon film and process adhere-combining by thermo-heating to become a filtration nonwoven finished product, its manufacturing process is simple and fast.

An image sensor module structure includes a substrate, a photosensitive chip, a lens holder, and a lens barrel. The substrate has an upper surface on which first electrodes are formed, and a lower surface on which second electrodes are formed. The photosensitive chip is mounted on the upper surface of the substrate, and is electrically connected to the first electrodes of the substrate. The lens holder has an upper end face, a lower upper face, and an opening penetrating through the lens holder. The upper end of the opening is formed with an internal thread, and the lower end of the opening is formed with a breach. The lens holder is adhered on the upper surface of the substrate by glue, therefore, the photosensitive chip is located within the opening of the lens holder. The lens barrel has an upper end face, a lower end face, and an external thread screwed to the internal thread of the lens holder.
摘要:
A basic board member includes an inner fabric member, and a gelatinous emulsion disposed on the inner fabric member, to form a gel outer layer on the inner fabric member, after the gelatinous emulsion is cured, to facilitate a low dielectric characteristic to the basic board member. The inner fabric member includes one or more fabric layers made of polytetrafluoroethylene (PTFE) material, and preferably inclined relative to each other, having an included angle of about forty five (45) degrees. An outer fabric layer may further be attached onto the fabric layer. The gelatinous emulsion may include a polytetrafluoroethylene emulsion and a coupling agent mixed and stirred together.
