摘要： The invention concerns a code with variable length of a type prefix/suffix ( [px..] sx), suitable for the parallel treatment of the words of said code, in particular for the compactation of said words into constant length packets at the transmission end and to the successive extraction at the receive end.
The code permits to separate at the receive end, the two operations of EXTRACTION and DECODING; essentially this may result in high speed applications wherein these operations cannot be performed within the clock cycle.
Besides said code permits the EXTRACTION operation to be simplified by considerably reducing the dimensions of the necessary hardware.
Its efficiency with particular distributions of messages is particularly high (97-98%).
Finally a detailed analysis is given of an application with a particular step code [px..] sx.
摘要翻译：本发明涉及一种具有类型前缀/后缀（[px ..] sx）的可变长度的代码，其适合于并行处理所述代码的字，特别是用于在传输时将所述字压缩为恒定长度分组在接收端连续提取。代码允许在接收端分离，EXTRACTION和DECODING的两个操作; 基本上这可能导致高速应用，其中这些操作不能在时钟周期内执行。此外，所述代码允许通过显着减少所需硬件的尺寸来简化EXTRACTION操作。其效率与消息的特定分布特别高（97-98％）。最后，给出了具有特定步骤代码[px ..] sx的应用程序的详细分析。

摘要： The filter according to the present invention has minimum dimensions, because the centers of cavities are foreseen in the apexes of a broken line, whose sides form among themselves angles greater than 90°. The filter body is preferably realized by pressure die-casting of an aluminium alloy having an high flowability in the dies: the dilatation coefficient of the cavities is compensated using, in the resonators and syntony screws, some materials different from the one of the filter body. The electric losses are minimized by differential ratios among the diameters of cavities (Dc) and of the relevant resonators. The weight is optimized by lightenings got by cavities realized in the body.

摘要： 57 The manufacturing process of printed circuit boards (pcb's), generally consisting of a support which on a major face or side carries circuit components according to the requested design and on its second major face or side carries the soldered wires corresponding to said circuit components, is now based on the fact that the designs of the component side, respectively of the soldering side are each transformed into labile electrostatic images on which good conductive metallic poweder (toner) is applied. The so obtained tracks are printed on insulating sheets (one printed with tracks reproducing the component side design, and an other with the tracks reproducing the solder side) and said printed sheets are fixed on the pcs rigid and thick support which is thereafter treated to enlarge adequately the conductive tracks.
