摘要： A method and apparatus for distributing melt through three level stack molds. According to the method a crossover manifold is provided between adjacent mold levels of the stack mold, the crossover manifold having a plenum generally coaxial with a mold axis. Melt is introduced into the plenum through an inlet passage and distributed from the plenum to respective nozzle arrays through a separate outlet conduit associated with each mold level. The apparatus includes a crossover manifold mounted between first and second mold levels and having a plenum generally coaxial with the mold axis. An inlet conduit fluidly communicates with the plenum and an injection head to provide a melt path from the injection head into the plenum. A separate outlet conduit is provided for each mold level. Each outlet conduit fluidly communicates at one end with the plenum and at an opposite end with the injection nozzles of a respective mold level to provide a melt path from the plenum to each of the injection nozzles of the respective mold level. Each outlet conduit defines a respective melt path of generally equal length and resistance to melt flow.

摘要： A network adapter is provided that controls the transfer of data between a host computer and a network medium in a manner which optimizes the amount of data transferred between the host computer and the buffer of the network adapter during a contemporaneous transfer of data between the network medium and the buffer. The network adapter optimizes the data transfer by dynamically determining when to make a bus request such that the buffer is capable of transferring a data packet of a particular target burst size at the end of an estimated latency period. The network adapter includes a buffer memory that transfers data between the host computer and the network medium and a buffer control logic that generates a first buffer data signal in response to the amount of data in the buffer memory. The adapter further includes a bus control logic that generates a second buffer data signal in response to previous transfers of data between the host computer and the network medium, and a dynamic bus request logic that asserts a bus request signal at a time responsive to the first and second buffer data signals to initiate an optimized data transfer between the host computer and the buffer memory during a contemporaneous transfer of data between the buffer memory and the network medium. In one instance, the target burst size is equal to the maximum amount of data transferred between the host computer and the buffer in a single transaction since the host computer has been powered on. Further, in one instance the estimated latency is set as the latency of the previous data transfer between the buffer and the host computer. 1. BACKGROUND OF THE INVENTION
摘要翻译：提供了一种网络适配器，其以在网络介质之间的同时数据传输期间优化在主计算机和网络适配器的缓冲器之间传送的数据量的方式来控制主计算机和网络介质之间的数据传输和缓冲区。网络适配器通过动态地确定何时进行总线请求来优化数据传输，使得缓冲器能够在估计的等待时间周期结束时传送特定目标突发大小的数据分组。网络适配器包括在主计算机和网络介质之间传送数据的缓冲存储器和响应于缓冲存储器中的数据量产生第一缓冲数据信号的缓冲器控制逻辑。适配器还包括总线控制逻辑，其响应于主计算机和网络介质之间的数据的先前传输而产生第二缓冲器数据信号，以及动态总线请求逻辑，其在响应于第一个时钟的时间断言总线请求信号以及第二缓冲器数据信号，以在缓冲存储器和网络介质之间的同时数据传送期间发起主计算机和缓冲存储器之间的优化的数据传输。在一种情况下，目标突发大小等于主计算机上电后单个事务中主机与缓冲区之间传输的最大数据量。此外，在一个实例中，将估计的等待时间设置为缓冲器和主机之间的先前数据传输的延迟。

摘要： In a computer system having a plurality of peripheral devices, a data transfer system for implementing transparent direct communication between the devices and the computer system. The system of the present invention includes a switch having a plurality of ports. Each of the plurality of ports is adapted to couple to a respective one of a plurality of devices. Each of the plurality of ports is further adapted to accept data from its respective device and transmit data to its respective device in a bi-directional manner. The switch communicatively couples a first pair of the plurality of ports to enable communication between their respective devices and communicatively couples a second pair of the plurality of ports to enable communication between their respective devices such that communication between the first pair of ports and communication between the second pair of ports occurs simultaneously and independently, thereby implementing efficient switched data transfers between the respective devices and greatly increasing the total data transfer bandwidth of the computer system.
