Abstract:
The present invention provides an asymmetric porous PTFE membrane for clothing having little change over time and conventionally known properties of a porous PTFE molded article such as water permeability resistance, air permeability, sealing properties and electric properties, in which durability and water vapor permeability are improved by strengthening adhesion strength with fabric. Specifically, the present invention relates to an asymmetric porous PTFE membrane for clothing comprising a dense skin layer and a continuously foamed porous layer, wherein(1) the contact angle of water to the surface of the skin layer is 120 to 140°; and(2) the diffuse reflectance of light of the skin layer is 91 to 94%.
Abstract:
The present invention discloses an infrared clinical thermometer device, wherein the ear thermometer casing has at least three light indicators; according to the measured temperature value, the microprocessor inside the casing generates a control signal and outputs the control signal to one of the light indicators; the control signal enables the light indicator to emit light to indicate to the user the state of the measured body temperature. In the present invention, light of different colors are used to indicate to the user the state of the measured body temperature; thus, the user can learn whether the body temperature is in the health state or in a fever state without watching the display but directly from the color of the emitted light; therefore, the operational convenience is greatly promoted. Further, in the present invention, a light source can be arranged beside the display, and the light source can emit a flickering light or a light of a specific color to illuminate the display to make the user read the measured temperature value easily; besides, the user can learn the state of the body temperature directly from the color of the light.
Abstract:
A polytetrafluoroethylene (PTFE) fiber includes a filament obtained by partially slitting an oriented PTFE film in a lengthwise direction of the film. Emboss processing is conducted linearly along the lengthwise direction of the film and like a zigzag shape or a convexo-concave shape in a width direction of the film, followed by slitting, whereby the filament includes a network structure in which single fibrils that are opened partially are arranged regularly. A PTFE short fiber is obtained by cutting the above filament and includes a branch structure. Thereby, a PTFE fiber with a small average fineness of single fibrils, a uniform fineness and a single-peak distribution with the peak at a center of fineness and with a high production yield and uniform and stable branch structure can be provided and a method for manufacturing the PTFE fiber can be provided.

Each modular unit has one or more interface connecting locations for one or more of a power connection, a thermal connection and data base connection, along with one or more of power, thermal and data transmission paths. Modular units can be united in an assembly, and at least some of the modular units have a switching system to selectively transmit and/or receive one or more of power, thermal and data transmissions.
Abstract:
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.
Abstract:
To provide a method of producing a uniaxially stretched polytetrafluoroethylene gasket tape, which comprises: (1) a step for preparing a paste comprising a mixture of a polytetrafluoroethylene powder obtained by emulsion polymerization and an extrusion aid, (2) a step for extruding the paste by means of an extruder equipped with a die which has plural separators inside an orifice thereof having a rectangular cross section, (3) a step for rolling, in the extruding direction, an extrudate having slit lines to give a rolled polytetrafluoroethylene sheet, (4) a step for uniaxially stretching the rolled sheet in the rolling direction after removing the extrusion aid from the rolled sheet, and (5) a step for heat-treating the obtained uniaxially stretched polytetrafluoroethylene sheet. The die of the extruder has plural sheet-like separators in the orifice thereof having a rectangular cross section. The separators are mounted so that free ends thereof are located at a point exceeding a center point of a long side of the orifice, and function to provide slit lines inside the extrudate in parallel with the long side of the orifice. The high performance inexpensive PTFE gasket tape is produced by the uniaxially stretching method and has properties equal to those of biaxially stretched PTFE gasket tape.

A computer enclosure assembly comprising of a generally box shaped computer chassis having a plurality of face portions including a first face portion, a first panel member removably mounted on the first face portion; and a latch assembly comprising a first latch portion on the chassis and a second latch portion on the first panel member. One of the first and second latch portions is trippingly deflectable to disengage the first latch portion from the second latch portion through application of pressure to a trip area, the trip area being hidden from view.
Abstract:
To provide a porous polytetrafluoroethylene sheet which has excellent cold flow resistance and is used suitably for gaskets and a highly densified polytetrafluoroethylene sheet which has high tensile strength and flex life and is used suitably for diaphragms. The porous polytetrafluoroethylene sheet is produced from a polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils and has MTS of from 3,000 to 12,000 psi and C.I. of 0.02 to 0.20 g/cc/psi. The highly densified polytetrafluoroethylene sheet is produced by compression-molding the porous polytetrafluoroethylene sheet and then sintering completely. The porous polytetrafluoroethylene sheet is also laminated with a sheet of other material to provide a composite polytetrafluoroethylene molded article.

Abstract:
Formulations for controlled, prolonged release of GM-CSF have been developed. These are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof with excipients and drug loadings that yield zero order or first order release, or multiphasic release over a period of approximately three to twenty one days, preferably one week, when administered by injection. In the preferred embodiment, the microparticles are microspheres having diameters in the range of 10 to 60 microns, formed of a blend of PLGA having different molecular weights, most preferably 6,000, 30,000 and 41,000. Other embodiments have been developed to alter the release kinetics or the manner in which the drug is distributed in vivo. For example, in some cases a polymer is selected which elicits a mild inflammatory reaction, for example, PLGA and polyanhydrides can act as chemoattractant, either due to the polymer itself or minor contaminants in the polymer, or polymers which are bioadhesive are used for transmucosal or oral delivery. In another embodiment, the GM-CSF is administered in a hydrogel which can be injected subcutaneous or at a specific site for controlled release. The microparticles or hydrogel are administered to the patient in an amount effect to stimulate proliferation of hematopoietic cells, especially white cells.
