An information processing apparatus is disclosed that updates a desired block data item contained in an archive file in an archive file format. According to an update instruction from an update instructing part, a predetermined data item contained in the archive file is protected before the archive file is updated. The content of the protected predetermined data item is updated based on updated content of the block data item contained in the archive file. The updated predetermined data item is written into the archive file into which the updated block data item is written.

Information processing apparatus and recording medium

A word information in a document printed on paper etc. may be specified easily. Especially, it enables to specify easily and correctly from the word information input partially. In one example, an information specification system specifying an arbitrary word information in a document, includes an information specification apparatus to select a specified candidate word information. The apparatus has document specification mechanism to input a specification information for specifying the document, and a character input mechanism to input the word information. The word information is searched in the specified document by using the word information which is partially input by the character input mechanism to select the specified candidate word information.

Apparatus, system, and server capable of effectively specifying information in document

A plurality of private address spaces where private addresses may possibly overlap are connected with a global address space. Respective private address spaces possess VLAN-IDs as identification information for VLANs. When connecting the respective private address spaces with the Internet, a duplicate network address translating device performs, with VLAN-ID and the private address of the respective private address spaces in pairs, mutual translation between the private address and global address of the Internet. A duplicate addresses-handling server is provided with a routing table which shows the relationship between virtual interfaces corresponding to VLAN-IDs and addresses of the respective private address spaces. A server portion of the duplicate addresses-handling server records, if a request is made from apparatuses of a private address space, the request and VLAN-ID, refers to, if making a response thereto, the routing table, selects a virtual interface which corresponds to the address of the response receiver, and makes a response. A virtual interface processing portion gives an applicable VLAN-ID and carries out an output to a switching hub.

A novel structure has, on a substrate a nonlinear optical thin film having a high .chi..sup.(3) value provided wherein metal fine particles are uniformly dispersed in a ferroelectric or highly dielectric matrix and heat treated whereby the metal fine particles and matrix are improved in crystallinity. The excitation wavelength can be substantially changed by a choice of the heat treating conditions. The crystallinity of the metal fine particles and matrix and .chi..sup.(3) value are improved by selecting a proper substrate or changing the heat treating procedure and conditions. The thin film is further improved in nonlinear optical properties, typically .chi..sup.(3) and .chi..sup.(3) /.alpha. values by using a perovskite type compound ABO.sub.3 having a specific A/B ratio as the matrix material and controlling film deposition conditions for improving the crystallinity of the matrix.
