Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.

Abstract: A heating roller includes a cylindrical member and a winding. The cylindrical member has a cylindrical body forming first and second sides along an axial direction. Plural wiring holes penetrate the cylindrical body along the axial direction and are each open on the first and second sides. The winding has a conductive wire penetrating the wiring holes. The conductive wire extends in opposite directions through each two adjacent wiring holes and is connected to a power source. Alternatively, the heating roller includes two windings each having plural conductive wires penetrating the corresponding wiring holes, wherein the conductive wires of one of the windings are connected to the positive and negative terminals of the power source at the first and second sides respectively, whereas the conductive wires of the other winding are connected to the negative and positive terminals of the power source at the first and second sides respectively.

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.

Abstract: A PTFE fiber with a low density and having a network structure that allows effective performances to be given to its finished articles and a method for manufacturing the PTFE fiber are provided. The PTFE fiber is a filament obtained by giving a heat treatment to a biaxially stretched polytetrafluoroethylene (PTFE) film, followed by slitting partially in a lengthwise direction of the film. The filament includes a network structured fiber in which single fibers are opened partially in the width direction, and the filament is an aggregate of the single fibers. This fiber is manufactured as the filament by feeding a biaxially stretched PTFE film to a revolving pin roll with needles implanted thereon, the needles being arranged so that a plurality of rows run obliquely along a circumferential direction at substantially regular intervals, and slitting the film partially in a lengthwise direction. This PTFE filament may be cut into short fibers with a cutter. The short fibers include a branch structure.

Abstract: A detecting method can perform the drop test according to the exact grounding condition, thereby detecting the actual grounding data. In addition, the shock accelerometer on the tested point of the test object can obtain an experimented G value which is compared with the simulated G value that is obtained by inputting the grounding angles (the grounding angles are calculated according to the grounding pictures) into the simulation program. In addition, the drop test device can reduce interruption, thereby enhancing the whole detecting accuracy.

Abstract: A testing device includes a housing having a number of openings formed in a partition for receiving a number of cups. The housing includes an x-axis track, a y-axis track and a z-axis track. A scale is moved along the x-axis track and the y-axis track of the housing to a position below the cups and is elevated to move the cups upward and to measure the changes of the weight of the cups in a suitable time interval. The cups may receive the desiccating agent, water or the plants whose weight are required to be measured frequently.
