Abstract: The present disclosure provides improved polypropylene-based compositions (formulations). The present disclosure further provides improved micro-pellets (non-foamed), which comprise the improved polypropylene-based composition. The improved polypropylene-based compositions have a reduced melting point (Tm) for the polypropylene resin while maintaining the stiffness of the micro-pellets for use in foaming procedures. Also, the disclosure further provides a new, dry method of preparing expanded polypropylene beads from micro-pellets without a liquid medium or steam, which thereby simplifies the production process and saves both energy and production costs.

Abstract: Polymer foam and a method for preparing the same are disclosed. In the present disclosure, the method sequentially comprises the following steps: providing a polymer body; performing a pressure-induced flow (PIF) process on the polymer body at a first predetermined temperature and a first predetermined pressure for a pressure holding time, to obtain a polymer sheet; and performing a foaming process on the polymer sheet by using a foaming agent at a second predetermined temperature and a second predetermined pressure for a saturation time, to obtain polymer foam.

Abstract: The present invention provides a method for scheduling jobs with idle resources. When the computational units of computers are idle, according to the variation of idle time, appropriate jobs may be allocated to the computational units. Then the unscheduled jobs may be completed by using idle time segments. Thereby, the utilization rate of computation resources and the completion rate of jobs may be enhanced.

Abstract: The present disclosure provides a process of preparing linear polypropylene foam, comprising the following steps: (a) preparing a specimen comprising at least one linear polypropylene; and at least one nucleating agent selected from the group consisting of alpha nucleating agents and beta nucleating agents; (b) deforming the specimen under a deforming pressure and at a deforming temperature for a period of time; and (c) subjecting the deformed specimen obtained in the step (b) to a foaming process to obtain the linear polypropylene foam. The present disclosure further provides a specimen after PIF treatment and a linear polypropylene foam prepared by the above process.

Abstract: A flip-flop circuit including a first logic circuit, a first master latch, a second master latch, and a slave latch is provided. The first logic circuit operates a logic operation on a selecting signal and a clock signal to generate a first control signal. The first master latch receives a data signal according to the first control signal and latches the data signal according to the selecting signal and the clock signal. The second master latch receives a scan data signal according to the selecting signal and the clock signal, wherein an output terminal of the second master latch is directly connected to an output terminal of the first master latch. The slave latch latches a signal on the output terminals of the first and second master latches for generating an output signal.

Abstract: A manufacturing process to make a valve ball includes the following steps: a) prepare a plurality of flat circular metallic plates; b) put the plate one by one into a pair of first molds and is punched into a top hat shaped piece; c) put the top hat shaped pieces individually into a pair of second molds and is punched an opening in the top of the crown and a rectangular indentation in a circumference of the brim; d) put the punched top hat again into a pair of third molds and where is punched into a hemi-spherical shaped piece; e) combine pair by pair of the hemi-spherical shaped pieces together with their rectangular indentations facing each other to form a rectangular retaining through hole, then connected by welding means. So that a qualified valve ball is therefore finished after the conducting of trimming, smoothing and polishing steps.

Abstract: A manufacturing process to make a ball valve of the present invention includes the following steps: a) prepare flat circular metallic plates each of which has a rectangular indentation in a circumference; b) mold those plates into bowl shape; c) remove the circular bottom of the bowl shapes to reform a hemi-spherical shape by another mold; d) weld each pair of the hemi-spherical shapes into a spherical shape each of which has a pair of aligned openings and a lateral rectangular through hole; e) trim and grind the uneven connection seam; and f) polish and smooth the outer surface to finished a qualified ball valve which has uniform arc and thickness.

Abstract: A method for operating a local device to permit a host computer to assert control over the local device via a communication port. A control available time window of prearranged duration is set up in the local device in response to a power on start condition. During this control available time window an Assert Control signal is received from the host computer. An Acknowledge Control signal is sent to the host computer upon receipt of the Assert Control signal during the control available time window. Then the local device responds to any control commands and data received from the host computer. Finally, the local device initiates processing of a normal local device application processes when no Assert Control signal is received during the control available time window or after the host computer has finished sending control commands and data to the local device.
