Abstract:
The PTFE real twist yarn of the present invention is a PTFE real twist yarn obtained by twisting a polytetrafluoroethylene (PTFE) multi-filament slit yarn. The yarn has a circular cross-section with a circularity in the range of 10/8 to 10/10, where the circularity is expressed by the ratio between the major axis width and the minor axis width, the average fineness of filaments is in the range of 1.5 to 200 dtex, a fineness D is in the range of 50 to 6000 dtex, and a twist coefficient K expressed by Formula (1) is in the range of 10000 to 35000: twist coefficient K=number of twists T×(the fineness D of the PTFE real twist yarn)1/2 (1) where the number of twists T denotes the number of twists per meter and the fineness D is a total fineness.
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.

The polytetrafluoroethylene film has a thickness ranging between 1 μm and 50 μm, and is preferably made of expanded porous polytetrafluoroethylene. The polymeric electret film has a surface potential ranging between 0.1 V and 1000 V.
Abstract:
A computing device may be joined to a cluster by discovering the device, determining whether the device is eligible to join the cluster, configuring the device, and assigning the device a cluster role. A device may be assigned to act as a cluster master, backup master, active device, standby device, or another role. The cluster master may be configured to assign tasks, such as network flow processing to the cluster devices. The cluster master and backup master may maintain global, run-time synchronization data pertaining to each of the network flows, shared resources, cluster configuration, and the like. The devices within the cluster may monitor one another. Monitoring may include transmitting status messages comprising indicators of device health to the other devices in the cluster. In the event a device satisfies failover conditions, a failover operation to replace the device with another standby device, may be performed.
Abstract:
The present invention discloses a respiration sensor, which is attached to a testee and comprises a triaxial acceleration sensing unit, a microprocessor, and at least one alarm unit. The triaxial acceleration sensing unit detects the respiration-related movements of a testee and output a detection signal. The microprocessor connects with the triaxial acceleration sensing unit, receives the detection signal and transforms the detection signal into a respiration signal to determine the respiration state of the testee. When the respiration signal is lower than a standard, the microprocessor triggers the alarm unit to give out an alarm to alert the persons nearby.
Abstract:
A system for dispensing adhesive onto a surface is provided. This system includes a dispenser and a quantity of discrete units of adhesive releasably deposited on a substrate. The dispenser includes a drive mechanism that further includes an actuator for actuating the dispenser; and a drive wheel, wherein the drive wheel further includes mechanical means for engaging the actuator. An optional supply wheel may be included in the dispenser. The quantity of discrete units of adhesive is releasably deposited on a substrate that may be mounted on the supply wheel or that may simply sit within the dispenser. The substrate further includes means for cooperating with the drive wheel to incrementally advance the substrate a substantially fixed, and predetermined distance upon actuation of the dispenser.
