Abstract:
A method for delivering an instant message in a server connected to two or more computers via a network is provided. The two or more computers include groupware clients in which a user can perform login at the same time, using the same user ID, and for which status that may be different from each other can be set. Embodiments of the method includes authenticating a user of a groupware client who attempts to perform login using a user ID, recording the user ID and status information in association with an instant messaging user ID, receiving an instant message addressed to the user ID, and determining, on the basis of the status information, which of two or more client computers the instant message is sent to.
Abstract:
The present invention is directed to realize a stable and highly-efficient quantum communication without being influenced by the jitter of the heralding signal. In regard to the quantum encryption transmitting apparatus 200, the pulse-driven heralded single-photon source 201 generates a photon pair, outputs one photon of the photon pair, and outputs the other photon of the photon pair as a heralding signal. The timing adjuster 202 synchronizes the heralding signal with a clock signal for pulse driving the pulse-driven heralded single-photon source 201, and outputs as a trigger signal. The quantum communication modulating unit 203 implements the signal modulation to a quantum signal, in timing with the trigger signal, and transmits the quantum signal to the quantum encryption receiving apparatus 300 via the quantum communication path 101. The heralding signal transmitting unit 205 transmits the heralding signal to the quantum encryption receiving apparatus 300 via the heralding signal communication path 102. The clock signal transmitting unit 206 transmits the clock signal to the quantum encryption receiving apparatus 300 via the clock communication path 103.
Abstract:
A method of controlling a gateway device includes the steps of converting a plain text mail received from a client device to an encrypted mail; transmitting the encrypted mail to a mail transmission server; and notifying a transmission error to the client device when the transmission error occurs between the gateway device and the mail transmission server is provided.
Abstract:
A method includes preparing a character string management table for managing character strings, a character string field, and a numerical field corresponding to the character string field in hierarchy structure data of a MOLAP, generating, in response to character string data being input into the character string field, a unique character string ID for a character string of the character string data and storing the character string ID into the numerical field, storing the character string ID and the character string data into the character string management table, calculating an aggregated value of the numerical fields by the numerical aggregation calculation of the MOLAP at a higher hierarchy layer of the hierarchy structure data, resolving the aggregated value into separate character string IDs at the higher hierarchy layer, and referring to the character string management table to obtain and display character string data corresponding to the resolved character string IDs.

Abstract:
A quantum-cryptographic communication system for quantum-cryptographic communication in an optical network, including a transmitter for transmitting a packet signal having a light pulse train representing an address and a single photon pulse train for quantum cryptography, and a router including a header analyzer for extracting the address information from the light pulse train of the packet signal and a gate switch for selecting one of the optical fibers. The router routes the packet signal by selecting an optical fiber used for the next transmission path according to the extracted address information by the header analyzer and by switching the path to the selected optical fiber by the gate switch.
Abstract:
A cipher mail server device includes a mail receiving unit, a management table, a determination unit and a processing unit. The mail receiving unit receives mail. The management table stores mail processing information indicating a processing content of mail for each account by associating with each account. The determination unit accesses to the management table when the mail receiving unit receives the mail, acquires the mail processing information associated with an account of a destination of the mail, and determines a processing content for the mail. The processing unit executes the processing content determined by the determination unit on the mail.
Abstract:
An image scanning device including a flat bed, a cover for the scanning table, a scanning portion, a carriage for supporting the scanning portion, an automatic document feeder (ADF), a detector for detecting a communication control signal from a remote communication device, and a controller. Upon detecting of the communication control signal (e.g. DIS signal), the controller causes the carriage to move from a stand-by position to either a scanning start position of the ADF, or a scanning start position for scanning a document placed on the flat bed, depending on whether a document is present or not present at the ADF. The time required between the user's pressing the start key and the start of the scanning is reduced.
Abstract:
In an optical pickup, an optical guide member is provided in an optical path of light from a light source, and has a plurality of inclined surfaces inclined with respect to a light beam emitted from the light source. A light-receiving element is provided for receiving light and for converting the received light into an electrical signal. The optical guide member and the light-receiving element are contained in a packaging member. The light beam from the light source is reflected by the plurality of inclined surfaces of the optical guide member, and then are directed to a recording medium. The reflected light from the recording medium is directed to the light-receiving element. At least one of dry air and inert gas such as nitrogen gas is charged in the interior of the packaging member at a pressure of 0.5 atm to 1.5 atm, thereby preventing the optical characteristics from being degraded.
