Abstract: The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting.

Abstract: Disclosed is a power semiconductor device and a manufacturing method thereof and, more particularly, a power semiconductor device and a manufacturing method thereof seeking to capture electrons trapped on one side of a transistor during transistor operation, prevent current collapse effects, and improve reliability consequently by forming or including one or more hole injection regions in a separation space between a gate electrode and a drain electrode.

Abstract: A power semiconductor device and a method of manufacturing the power semiconductor device are disclosed. The power semiconductor device includes an isolation region at or in a bather layer in contact with or adjacent to a drain electrode to reduce or prevent current collapse between a gate electrode and the drain electrode.

Abstract: Embodiments of the present application provide an XML based custom code generating method and an XML based custom code generator, a computer program product and a computer readable medium. The method comprises: obtaining code source information, user custom template file information and a prestored code output format rule; preprocessing the code source information, classifying the code source information and storing the same into a code source container; dynamically replacing a corresponding description part in the user custom template file with the corresponding classified code source information stored in the code source container; and outputting codes in the replaced user defined template file according to the prestored code output format rule. With the method and generator, repeated code can be automatically implemented during the development process, custom extension can be flexibly implemented, the workload of engineers can be reduced and the stability of the system is improved.
