Abstract:
In a thermal recording system wherein a linear array of elemental resistance electrodes is employed to record received data bits which are organized into data segments of equal bits, the resistance array is divided into a plurality of identical blocks (#1 to #64) corresponding to the data segments. Successively arranged resistance blocks are selected by a selector (42) in response to first and second write-command pulses supplied from pulse generators (22, 24) in synchronism with the receipt of each data segment to record black dots corresponding to the received data bits. The first and second write-command pulses are generated so that the period of each pulse partially overlaps the period of the other, whereby the preceding resistance block is selected simultaneously with the subsequent one after the corresponding data bits have been removed. After-effect currents are supplied to the preceding block to increase the image density of the recorded black dots while the recording of the subsequent data segment is in progress. The after-effect currents are not sufficient to heat up the resistance elements which correspond to white areas.
Abstract:
Method for terminating a startup session of a full duplex or half duplex communication to be established between a central terminal and the remote terminal. When predetermined data is transmitted upon reception of an ACK message transmitted by one of the central or remote terminals, a data transmission in the startup session is suspended. If the other one of the central or remote terminals receives the predetermined data and thereafter detects a predetermined period of silence, the startup session is terminated.
Abstract:
A facsimile receiver, wherein the carrier, which is necessary to reproduce the carrier in the case where the received signal is demodulated through synchronous detection, is reproduced exactly in the carrier reproducing means in the facsimile receiver before the arrival of the picture signal at the facsimile receiver, by supplying also to the demodulating means the communication control signal to be sent from the facsimile receiver to the transmitting station before the transmission of the picture signal from the transmitting station. Moreover, by operating the PLL circuit in the carrier reproducing means in response to all the carrier components in the picture signal, a very quick compensation can be made for phase jitter generated in the telephone circuit so that an exact carrier can be maintained, and the distortion of the reproduced picture can be minimized.

PROBLEM TO BE SOLVED: To use password authentication using data packet communication and voice authentication using voice calling in combination. SOLUTION: A WEB server 11 when authenticating a user with a password issues a reception code and gives notice to a voice authentication server 12 and a portable telephone 8 (ST707, ST709). The voice authentication server 12 performs voice authentication by communicating with the portable telephone 8 (ST713, ST714). Then the reception code is sent back to the WEB server 11 together with a voice authentication result (ST715). The portable telephone 8, on the other hand, sends a reconnection request message including the reception code to the WEB server 11 (ST718) after the voice authentication is completed. The WEB server 11 compares the reception codes which are received from both with each other (ST720) and provides services to the terminal (ST721, ST723) only when the both match each other and the user is authenticated through the voice authentication.
Abstract:
PROBLEM TO BE SOLVED: To appropriately apply transfer processing to received image informa tion without causing useless transfer of even received unwanted image informa tion or inconvenience requiring re-transfer. SOLUTION: When image information received on a prescribed line among two or more lines satisfies prescribed conditions, the information is transferred to a prescribed transfer destination. Thus, when transfer setting is performed, the received image information is transferred and when performing transfer, corresponding to the line, on which the information is received, the received image information is transferred to an arbitrary transfer destination so that the received image information can be selectively transmitted corresponding to that receiving line. Besides, the transfer is to be performed when transfer setting is executed. When transfer setting is not executed, even the image information received from a line is not transferred but recorded out. Thus, even when transferring the information corresponding to the receiving line, the image information received from the prescribed line is not always transferred and useless transfer of even received unwanted image information can be prevented.

Abstract:
PROBLEM TO BE SOLVED: To make an observer detect a communication error by observing the reception state based on an eye pattern detected from a reception signal with respect to communication using a multicarrier. SOLUTION: With respect to communication using the multicarrier, an error quantity which is the amount of difference between the coordinate point of the eye pattern detected from an actual reception signal in each sub-carrier and that essentially scheduled from the reception signal is calculated by an eye pattern display control part 105 and is displayed on an oscilloscope 107.
