Manufacturing method of push-button switch

Номер: US20120227251A1
Автор: Haruaki Miyamura, Keiichi Fukuda, Norio Suzuki, Shunta Hyuga
Принадлежит: Shin Etsu Polymer Co Ltd

In a manufacturing method of a push-button switch, a key-top end of a pressing element 25 is inserted into a lower-mold recess for the pressing element, which is provided in a surface of a lower mold. A reinforcing plate 28 is placed in the lower mold so that the pressing element 25 extends through a plate through hole of the reinforcing plate 28. An upper mold and the lower mold are moved toward each other so as to insert the other end of the pressing element 25 into an upper-mold recess for the pressing element, which is provided in a lower surface of the upper mold. A liquid silicone rubber 27, which contains a component that does not adhere to the upper and lower molds but adheres to the pressing element 25, is introduced into a cavity. After the upper and lower molds are pressed and held at a predetermined temperature for a predetermined time, the upper and lower molds are opened to remove a molded product in which an intermediate portion in an axial direction of the pressing element 25 is supported in the plate through hole by the silicone rubber 27. A back surface of a key top 26 is attached to the key-top end of the pressing element 25 in the molded product. Thus, the pressing element and the elastic member are easily and reliably integrally molded by using the elastic member, and durability of the push-button switch is improved.

A nucleating system for a thermoplastic composition that contains a polyarylene sulfide is provided. The nucleating system includes a combination of an inorganic crystalline compound and an aromatic amide oligomer. The present inventors have discovered that the combination of these different types of nucleating agents result in excellent crystallization properties (e.g., rate of crystallization). Due to the improved crystallization rate, the thermoplastic composition can be molded at lower temperatures to still achieve the same degree of crystallization. In addition to minimizing the energy requirements of the molding operating, the use of lower temperatures can also decrease the production of “flash” normally associated with high temperature molding operations. The composition may also possess good viscosity properties that allow it to be readily molded into parts of a variety of different shapes and sizes.

The present disclosure relates to the use of occluding fluids, such as a high-density fluid (a “z-fluid”) or a low-density fluid (an “a-fluid”), to displace resin within a vat during 3D printing. Further, an a-fluid may act as a protective boundary for a 3D printing resin wherein the a-fluid sits on top of the printing resin. Another embodiment of the disclosure provides a process of assessing which regions of a computer-aided design (CAD) model take advantage of a buoying force supplied by the occluding fluid, such that fewer support structures are needed for printing a final CAD model compared to printing the CAD model without the occluding fluid.

A medical tube having improved lubricity is disclosed. The medical tube is produced by extruding a polymer material blended with a lubricity enhancing additive through a resilient die. The polymer material can be medical-grade high-density polyethylene, and the lubricity enhancing additive can be a silicone-based or alloy-based material. The medical tube can include one or more internal elongated protuberances so as to reduce the internal surface area of the medical tube available to generate friction on a guide wire inserted or withdrawn through the medical tube. 1. A lubricious medical tube formed from a blended material including:organic polymer resin; anda lubricity enhancing additive including siloxane is blended with the organic polymer resin to form a blended material, the lubricity enhancing additive being blended with the organic polymer resin at a concentration of less than 10%,wherein the blended material is disposed in a substantially tubular configuration bounded by an inner surface and an outer surface encompassing the inner surface.2. The lubricious medical tube of claim 1 , wherein the organic polymer resin is medical grade high-density polyethylene.35-. (canceled)6. The lubricious medical tube of claim 1 , wherein the lubricity enhancing additive is blended with the organic polymer resin at a concentration of less than 5%.7.

METHOD TO FABRICATE PRE-PATTERNED SURFACES DURING MANUFACTURE OF COMPLEX WRINKLED STRUCTURES

Номер: US20160039142A1
Автор: Culpepper Martin Luther, SAHA Sourabh Kumar
Принадлежит:

The pattern complexity and functional value of wrinkled structures can be substantially increased by fabricating the wrinkles on pre-patterned quasi-planar substrates instead of flat substrates. This disclosure presents the methods for fabricating pre-patterned polymeric surfaces that can be subsequently used as the substrates during manufacture of complex wrinkled structures. Pre-patterned substrates are generated by imprinting the pre-patterns onto the substrates during the curing process. Suitability for post-curing use in fabrication of wrinkles is ensured by (i) delayed imprinting that occurs close to but before the gelation point and (ii) gradual alignment of pre-patterns to the direction of stretch that is applied later during manufacture of wrinkled structures. 1. A method to fabricate a pre-patterned base substrate by replicating a patterned surface for subsequent use during manufacture of wrinkled structures , comprising:providing a coupon with a patterned surface, wherein the coupon has alignment features;providing a thermally curing base material, wherein the base material undergoes a liquid-to-solid phase transition during curing;providing a mold for curing the base material, wherein the mold surface has alignment features that correspond to the direction of stretch during subsequent manufacture of wrinkled structures;heating the base material to a temperature below a threshold value to initiate the first thermal curing cycle, wherein the viscosity of the base material increases with time but the base material does not undergo a liquid-to-solid phase transition by the end of the cycle;aligning the patterned surface to the direction of stretch by locating the alignment features on the coupon with respect to the alignment features on the mold, wherein the patterned surface is not yet in contact with the base material;partially placing the coupon with the patterned surface on top of the base material, wherein only one edge of the coupon makes contact with ...
