Flag sequence

Abstract: PURPOSE:To attain the processing of encipherment and decoding in high speed by providing a means changing timewise a synchronizing code representing the start/end of a frame being the unit of sent information and a means disabling the mixture of the synchronizing code and the information in other frame. CONSTITUTION:Random number generators 30, 150 and memories 50, 130 are added to a data terminal equipment is a communication line to add the processing such as addition, deletion of the start/end flag sequence of a frame and disabled mixture between the flag sequence and other bit pattern in the frame to data terminal equipments 10, 170. Then a flag sequence corresponding to each flag control number, a bit inserting location and a bit pattern are stored in the memories 50, 130, a signal is sent from the data terminal equipment 10 and received by the data terminal equipment 170, then the flag sequence, bit inserting location and bit pattern in response to the flag control number are inputted.

Abstract: The present invention belongs to the field of protein separating and purifying technology, and provides one kind of tandem affinity purified vector for mammal cell and its preparation process and usage in purifying protein composition Tandem affinity purification (TAP) is used in separating protein composition and researching protein-protein interaction in physiological condition The present invention has two Flag sequences to replace the protein A flag sequence in initial TAP vector and the decreased flag molecular weight is favorable to the effective fusion expression between the foreign target gene and the TAP vector and the high affinity combination to the Flag resisting monoclonal antibody Therefore, the TAP vector is used in separating protein composition of higher mammal cell effectively and simply

Abstract: PROBLEM TO BE SOLVED: To shorten time required from the line when reception becomes impossible up to the line disconnecting by starting clocking when a flag sequence from a reception-side facsimile equipment is interrupted during the transmission of picture data and disconnecting the line when a valid signal is not detected until prescribed time passes SOLUTION: When that the flag sequence (Flags) from the reception-side facsimile equipment is interrupted is detected based on a flag sequence detection part in spite of facsimile encoding data (FCD) is transmitted from a transmission-side facsimile equipment, the clocking of prescribed time (T6a time out) which is newly set is started T6a time out is reset by the reception of the flag sequence or the invalid signal or T6a time out When the flag sequence (Flags) or the invalid signal is not received even if T6a time out passes, a cut instruction (DCN) is transmitted and the line is cut

Abstract: PURPOSE: To improve the essential transmission efficiency by reducing the generation frequency of the re-sending requesting processing of command data and the processing of the line cut-off due to the time-out. CONSTITUTION: At a transmitting side, command data to be transmitted are prepared to a basic frame in accordance with the frame constitution of an HDLC procedure and the basic frame is sent through a flag F as the transmission frame DF of plural continuous modes. At a receiving side, when the above-mentioned transmission frame DF is received, until one basic frame completes to read without detecting a receiving error, the synchronization is performed by the detection of the flag F in the transmission frame DF, the basic frame reading processing to read the data in the basic frame in succession to the flag F is repeated, and the command data on the transmission frame DF are read.
