Abstract: A packet processing device has a search engine module including an associative memory for transferring a packet on the basis of an entry mapping to route information, a first processor taking charge of a pre-search process before a process of the packet to the search engine module, and a second processor taking charge of a post-search process for executing a process of routing the packet on the basis of a search result of the search engine module. In this architecture, the packet processing device further has a table used for transferring and receiving information between the first processor in charge of the pre-search process and the second processor in charge of the post-search processor, and identifying information in a specified field of the table is transferred through the search engine module as a transparent medium.

Abstract: An improved composite copying apparatus which is so arranged that, with an image area once set being memorized, a trimming mode and a masking mode are exchanged with respect to the same image area in each of the copying processes for two times, while the two copying processes can be continuously effected by a two-surface continuous copying device and a circulation transport device, whereby setting of modes, inputting of data, and setting of original documents and paper sheets may be eliminated at the second copying process for simplification of the composite copying operation.

Abstract: An electronic device, includes a first panel on which a plurality of first terminals are disposed at a pitch in parallel with each other, a second panel on which a plurality of second terminals are disposed in parallel with each other and at substantially the same pitch as that for the first terminals, and a pair of dummy electrodes respectively disposed on the first and the second panel. The pair of dummy electrodes have widths which are smaller than the widths of and the spacings between the first and second terminals, respectively, and are disposed in such a manner that they are electrically connected to each other when the first and second terminals are disposed at the right positions in alignment with each other.

Abstract: An optical modulator having a layer of optical modulating substance between a pair of electrode-supporting plates is provided, which is characterized in that at least one of the electrode-supporting plates is provided with a mark for registration and the other substrate is provided with a projection for registration at the position corresponding to that of the mark for registration.
