Abstract: In cell transfer in which cells are sent at uniform intervals, in a case in which 18 cells have been lost between cell A (SN=2) and cell B (SN=5), every time 8 times the expectation value T of the cell arrival interval elapses after the arrival of cell A a dummy cell having the same sequence number as cell A (SN=2) is written into the cell FIFO section. Cells or dummy cells are stored in the cell FIFO section in the order SN=2, 2, 2, 5. When cells or dummy cells are read out of the cell FIFO section in order, if the sequence number SN=2 appears twice in a row, dummy data are created corresponding to the cells SN=3, 4, 5, 6, 7, 0, 1; if the sequence number SN=2 is followed by SN=5, then dummy data are created corresponding to SN=3 and 4.

Abstract: A detection sheet capable of detecting an antigen or antibody in a biological fluid with a high sensitivity in a simple operation, as well as a detection kit and detection method using the detection sheet. The detection sheet comprises (a) a fibrous aggregate with carried particles of a calcium phosphate compound having an average particle diameter of about 0.01 to 200 microns and a Ca/P ratio of about 1.0 to 2.0, and (b) an avidin, streptavidin or avidin derivative from which carbohydrates have been extracted immobilized on said calcium phosphate compound. After a biotinylated antigen or antibody is bonded to the immobilized avidin, streptavidin, or avidin derivative of the detection sheet, the detection sheet is contacted with a test solution to thereby bond an antigen or antibody of the test solution to the detection sheet.

Abstract: An internal timing information producing portion produces internal timing information IRTS1 to IRTS4 which is the timing information on a data reception clock by using a network clock C.sub.N and the data reception clock C.sub.RU. A calculator calculates the difference between the internal timing information IRTS1 to IRTS4 and the transmission timing information RRTS1 to RRTS4 contained in a received cell, and a data reception clock producing portion adjusts the timing of the data reception clock C.sub.RU so that the difference is zero and outputs the adjusted timing. An ATM cell decomposing portion outputs the user data D.sub.RU in synchronism with the data reception clock C.sub.RU which is input from the data reception clock producing portion.

Abstract: In an ATM communication system, in order to prevent a user from an unnecessary charge due to omitting AIS (Alarm Indication Signal) transmitted/received between a transmission side ATM unit and a receiving side ATM unit when a loss of service occurs in a communication network in which existing communication lines are connected by an ATM communication unit, the transmission side ATM unit is configured to monitor a signal received from a communication line on the transmission side and to stop transmission of ATM cells to the receiving side ATM unit for a certain period of time when it detects an AIS signal indicating a loss of service on the transmission side.

Abstract: A granular polymer composite comprising polymeric granules having coated on a surface thereof a calcium phosphate compound, at least a part of the particles of the calcium phosphate compound penetrates into the polymeric granules. The composite has a high bonding strength between the polymeric granules as a matrix and a coating of the calcium phosphate compound and also can fully exhibit the functions of a calcium phosphate compound. Using the granular polymer composite, a diagnostic agent which comprises of an antigen or antibody is adsorbed and immobilized on the composite and is therefore useful in diagnostic tests utilizing an antigen-antibody reaction for a number of infectious diseases.
