The present invention provides a system and apparatus for efficient and reliable, control and distribution of data files or portions of files, applications, or other data objects in large-scale distributed networks. A unique content-management front-end provides efficient controls for triggering distribution of digitized data content to selected groups of a large number of remote computer servers. Network distribution messages are dispatched according to a sorted list of servers, based on factors such as nearness, server processor speed, reliability, and CPU Usage. For large numbers of servers, a store-and-forward approach becomes much more efficient. A first selected server receives the message from a content control manager (CCM). The first server requests instructions for the next server listed on an ordered list in the CCM and forwards a copy of that message to the next identified server. Each server reports its completion and requests further instructions from the CCM. This mechanism permits highly efficient and robust distribution of assignments and data content from the CCM to each required GL using a store-and-forward tree structure.

The present invention provides a molding method capable of molding a thick-walled light guide plate of high quality by a short molding cycle. A predetermined amount of a molten resin is charged in the shaping space K constituted of the stamper (8) provided to the core (4) on the cavity side of a fixed mold, the core 23 on the core side of a movable mold and cores 30 and 30 on the peripheral wall side of the movable mold.

By this constitution, the cooling speed of the cores (30 and 30) on the peripheral wall side becomes slow to enhance a compression effect and the occurrence of a sink is suppressed.

A filter amplifier is composed of a first mixer, a first surface acoustic wave filter, an amplifier with a gain controllable, a second surface acoustic wave filter and a second mixer, wherein the first mixer, the first surface acoustic wave filter, the amplifier with the gain controllable, the second surface acoustic wave filter and the second mixer are sequentially connected. The first mixer is used for receiving an input signal and a first local oscillator signal and down-converting the input signal into an intermediate-frequency signal. The intermediate-frequency signal is filtered through the first surface acoustic wave filter and then is output to the amplifier with the gain controllable to be amplified. The amplified signal is input again to the second surface acoustic wave filter and filtered again. The signal filtered again is up-converted to a frequency through the second mixer and then output, wherein the frequency is wherein the input signal is originally located. A first local oscillator circuit is in connection with the first mixer so that the stable first local oscillator signal can be supplied to down-conversion of the first local oscillator circuit. The frequency of the first local oscillator signal changes following the change of the input signal, and the intermediate-frequency signal can be a fixed value from beginning to end. A second local oscillator circuit is in connection with the second mixer. According to the filter amplifier, data timing transfer (DTT) signal transmission can be perfectly compatible with a 4G long term evolution (LTE) signal.
