Abstract: A system adapted to process long-running processes is disclosed. A request to upload data is received at a server. The server divides the data into multiple parts and launches a separate process to upload each of the divided parts. The server records for each process the processing time or duration that the particular process used to upload its corresponding data item. The server maintains an average processing duration that is calculated from the processing durations of the completed processes. The server identifies that one process is continuing to run and compares a processing duration for the particular process to a threshold derived from the average processing duration. If the processing duration for the particular process exceeds the threshold, the server initiates a new process to upload the same data item. When one of either the new process or the still running process has completed processing, the server terminates the other process.

Abstract: In an automated molding machine for ultra small draft angle slurry molding products, a righting gear of a righting mechanism drives a turning mechanism to perform a turnover action to assist righting an ascending or descending action along a righting rack of a righting shaft synchronously. When a slurry suction die is moved up and down and/or turned over, the slurry suction die can be ascended to a designated position through the righting provided by the righting gear and the righting rack to achieve a precise closing when the slurry suction film is carried, ascended and closed with an extrusion die or descended and closed with a moving mold. Meanwhile, the extrusion die is controlled by a power cylinder to perform a descending stroke and close the mold with the slurry suction die.

Abstract: A charge pump circuit used for a charge pump phase-locked loop that includes a charging and discharging unit, two complementary circuit units, two operational amplifier units, an inverter unit, and a current mirror unit. The charge pump circuit resolves the matching problem of charging and discharging currents and the charge sharing problem in existing charge pump circuits. Both complementary circuit units positively and reversely compensate the charging and discharging unit to keep the charging and discharging currents of capacitors constant. Thus, the problem of the change of charging and discharging currents is resolved, the voltage linear variation of the charge pump capacitors is achieved, and the charging and discharging of the capacitors can be accurately controlled. The charge pump circuit is simple in structure, easy to integrate, high in the matching precision of the charging and discharging current sources, and suitable for low voltage and low power consumption applications.
