摘要： The disclosed method of controlling a pressurizing pin, which serves to replenish for the necessary locality with molten metal during solidification of molten metal charged in the cavity, features that the operation of the molten metal replenishment by the pressurizing pin is caused when it is detected that the volume of non-solidified metal has become less than the volume effective for obtaining a molten metal replenishment effect. It is thus possible to obtain efficient replenishment for the necessary locality with molten metal by using a pressurizing pin which is limited in size and stroke.

摘要： A pressure casting method is disclosed, which permits sufficient pressurizing effect to be obtained for the entire molten metal by varying the speed of advancement of a pressurizing pin according to the state of solidification of the molten metal during pressurizing. In pressure casting using a pressure casting apparatus, while charged molten metal is solidified, it is pressurized by causing advancement of the pressurizing pin into a cavity of the die. During this time, the reaction force received by the pressurizing pin from the molten metal is measured by a pressure sensor, and the speed of advancement of the pressurizing pin is varied through control of the opening degree of a flow control valve according to the measured reaction force. While the reaction force during the progress of solidification of molten metal is high, the flow control valve is controlled to a high opening degree to provide for a high speed of advancement of the pressurizing pin so as to apply a high pressurizing force. On the other hand, while the reaction force is low so that there is a delay in the solidification of molten metal, the speed of advancement is reduced so that no pressurizing force is applied until completion of solidification of molten metal. The pressurizing pin is advanced while its advancement speed is controlled in the above way, and pressurizing over the entire stroke is completed.
摘要翻译： 公开了一种压铸法，其通过根据加压期间的熔融金属的凝固状态改变加压销的前进速度，从而对整个熔融金属获得足够的加压效果。 在使用压力铸造装置的压力铸造中，当充入的熔融金属固化时，通过使加压销进入模具的空腔而被加压。 在此期间，通过压力传感器测量加压销从熔融金属接收的反作用力，并且通过根据所测量的反应来控制流量控制阀的开度来改变加压销的前进速度 力。 当熔融金属凝固进行期间的反作用力高时，流量控制阀被控制到高开度，以提供加压销的高速推进以施加高的加压力。 另一方面，当反作用力低时，熔融金属的凝固延迟，提前速度降低，直到熔融金属凝固完成之前不施加加压力。 加压销前进，其进给速度以上述方式控制，并且整个行程的加压完成。

摘要： The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. Then, solutions of first and/or second binding agents are printed on the powder bed in a predetermined pattern. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The removable binding agent is then removed. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

摘要： A virtual machine can be extended to be aware of secondary cores and specific capabilities of the secondary cores. If a unit of platform-independent code (e.g., a function, a method, a package, a library, etc.) is more suitable to be run on a secondary core, the primary core can package the unit of platform-independent code (“code unit”) and associated data according to the ISA of the secondary core. The primary core can then offload the code unit to an interpreter associated with the secondary core to execute the code unit.
摘要翻译： 可以扩展虚拟机以了解次级核心和次级核心的特定功能。 如果独立于平台的代码（例如函数，方法，包，库等）的单元更适合在次级核心上运行，则主要核心可以将平台无关代码的单元（ “代码单元”）和根据次级核的ISA的关联数据。 然后，主核心将代码单元卸载到与次级核心相关联的解释器以执行代码单元。
