摘要:
A computer program, apparatus, and method for managing access to documents, capable of identifying the exact events of document access on the basis of given access logs even when access policies are modified in the middle of operations. Upon receipt of an access policy setup request from a first client, an access policy manager adds a new access policy to the access policy database or modifies an existing access policy in an access policy database according to the request. A policy log collector then stores the records of such a new access policy or modified existing access policy in a policy log database. Afterwards an access log collector receives an access log for the document 5 from the second client 3 and saves it in the access log database 1c. When a third client issues a log request with a specific search keyword, a log searcher retrieves relevant policy log records and access log records that match with the specified search keyword.

There is provided a layer forming apparatus for forming a photosensitive layer of an electrophotographic photoreceptor, containing no bubbles in a coating liquid. In the layer forming apparatus for forming the photosensitive layer of the electrophotographic photoreceptor through the dip coating method, a lower end port of a dipping cylinder is distanced away in a horizontal direction from a coating liquid discharge port, and the coating liquid discharge port is disposed above the lower end port of the dipping cylinder, in order to prevent a bubble from moving into a coating liquid portion used for actual coating even when a bubble exits in the course of circulation of the coating liquid.

An electronic image data verification program disclosed herein is capable of detecting presence or absence of a change, specifying a changed portion (the position of a change) if present, and making the presence or absence and the changed portion provable to third parties, by generating partial signature information separately from electronic image information to be registered, by dividing and maintaining the partial signature information, and by clearly separating functions/roles of the electronic image information (original information) and the partial signature information (verification information). The present invention comprises: a partial signature information generation section 40 that uses partial information of electronic image information, to generate partial signature information for specifying presence or absence of a change to the electronic image information and a changed portion if a change has been made; a registration section 70 that registers the electronic image information and the partial signature information generated from the electronic image information; a storage section 80; and a partial signature verification section 50 that uses the electronic image information and the partial signature information registered by the registration section, to verify presence or absence of the change to the electronic image information, or a changed portion if a change has been made to the electronic image information.

Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identification information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.
摘要:
A lightweight insulated electric wire and an automobile wire harness using the same insulated electric wire where the insulated electric wire has a conductor portion including one or more first wires and one or more second wires, which are stranded together. The first wires are constituted by metal wires made from at least one type of metal selected from copper, copper alloy, aluminum and aluminum alloy. The second wires are constituted by metal wires different from the first wires and have a relative permeability of 4.0 or less.

A solid electrolytic capacitor includes a capacitor element provided with an anode body from which an anode lead projects, an anode-side lead frame positioned below the anode lead, and a bolster member which is provided between the anode lead and the anode-side lead frame and electrically connects the anode lead and the anode-side lead frame. At least one portion of the anode lead cuts into the bolster member.

The present invention is directed to provide an underwater detection system which can determine frequency components contained in echoes arriving from all azimuthal directions at high speed and enhance target discriminating capabilities by presenting such frequency components.The underwater detection system rotates a pair of ultrasonic receiving beams having a fixed phase angle difference, measures phase differences between two signals picked up by both ultrasonic receiving beams, determines carrier frequencies contained in target echoes from the phase differences, derives magnitudes and directions of moving velocities of targets from the carrier frequencies, and displays such target data in different colors. Furthermore, it provides such information as over-the-ground velocities of targets themselves upon compensating target velocity data with ship velocity data.

A water-based surface treatment agent is used to provide a chemical layer on a copper or copper alloy printing wiring board (PWB). The chemical layer shows excellent heat-resistance and moisture-resistance. The treated PWB maintains excellent solderability for extended lengths of time. The water-based surface treatment agent contains as an active ingredient 2,4-diphenylimidazole, 2,4-diphenyl-5-methylimidazole or 2-phenyl-4-benzyl-5-methylimidazole. The treating compositions with a lower carboxylic acid of up to 4 carbon atoms are soluble in water, and have improved solder wetting properties and improved solder paste spreading property. A copper compound may be included in the aqueous solution to increase the rate at which the chemical layer is formed.

Disclosed is a positively chargeable toner comprising, as a charge-controlling agent, an acid adduct, metal complex or derivative of a 2-alkylimidazole represented by the following formula: ##STR1## wherein R.sub.2 stands for an alkyl group having 11 through 17 carbon atoms, and R.sub.4 stands for a hydrogen atom or a methyl group.In this toner, a high charge-controlling effect is attained with a small amount of the charge-controlling agent, and since the charge-controlling agent has a white color or light color, this toner is advantageously used as an electrostatic photographic toner for the color printing.

An image managing method includes dividing the original moving image into a header and a body and generating the group hash value of the header portion, generating the hash value of each item of still image data, connecting the group hash value of the header portion and the hash value of each item of still image data to generate connected hash values, generating a group of the connected hash values as a hash value list, generating the hash value of a Huffman table on the basis of cutting out one still image, and signing to generate signature information of the original moving image, using the group hash value of the header portion, the hash value of the Huffman table, and the hash list as verification data of the original moving image, by adding a digital signature of a video recording terminal to it.
