Granted: 1997-04-15
Abstract: A multiplex-packet band learning system and method wherein management of the transmission band of a trunk suit-able for an actual packet communication amount can be estab-lished to contribute to efficient multiplex packet communica-tion.  The number of communication packets per unit time for each medium pattern corresponding one of combinations of call terminal attributes is measured for the trunk interface of each exchange, a normal distribution of the numbers of commu-nication packets in actual communication is estimated on the basis of the measured number of communication packets per unit time for each medium pattern, and its estimated value is updatingly held as index data of permission or prohibition of a new call registration.  The number of communication packets in the actual communication is measured at a terminal inter-face so that a terminal band table for the terminal interface has packet rates at which the terminal has been so far commu-nicated, mean and variance values of the past packet rates are calculated on the basis of the actually measured number of communication packets, a normal distribution is estimated at PPLs of a controller with use of its measured statistical data, and it is judged whether the packet communication of a call requiring the registration to the corresponding trunk line is permitted or prohibited.

Granted: 2001-09-18
Abstract: A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a protein to produce library of mutants. The method is based on the premise that certain amino acids play crucial role in the structure and function of proteins. Libraries can be generated which contain a high proportion of the desired mutants and are of reasonable size for screening. These libraries can be used to study the role of specific amino acids in protein structure and function and to develop new or improved proteins and polypep-tides such as enzymes, antibodies, single chain antibodies and catalytic antibodies.

Patent CA-2096928-C (CA)
Inventor: LAL GAURI S
IPC: C07C25/13
Filed: 1993-05-25
Granted: 1998-08-25
Abstract: The invention describes a process for selectively preparing ortho-fluorinated substituted aromatic compounds wherein an aromatic compound containing a substituent capable of directing ortho metalation is contacted with a metalating reagent under reaction conditions sufficient to form an ortho-metalated substituted aromatic compound. The ortho-metalated substituted aromatic compound is reacted with an electrophilic fluorinating reagent under reaction conditions sufficient to form the desired ortho-fluorinated substituted aromaticcompound which is then recovered from the reaction mixture. The process which utilizes a metalation intermediate prior to effecting the electrophilic fluorination step overcomes problems associated with prior art electrophilic fluorination processes which do not proceed through a regiospecifically controlled intermediate.
Patent CA-2100101-C (CA)
Inventor: YOSHIMURA SHUJI
IPC: H04L12/70
Filed: 1993-07-08
Granted: 1999-08-24
Abstract: A first terminal unit is connected to a line switch via a set of data lines. A second terminal unit is connected to the first terminal unit via a set of data lines. A third terminal unit is connected to the second terminal unit via a set of data lines. Therefore, the terminals are sequentially connected in series. Cells transmitted to the terminals are multiplexed by each terminal and sequentially transmitted upstream, to the third terminal unit, the second terminal unit, and the first terminal unit together with a token.      Since the first terminal unit receives a first identification signal from a switch and a second identification signal from downstream, the first terminal unit recognizes that it is the highest order terminal unit, and sends a cell to the switch after separating the cell from a token which is to be returned downstream. Since the second terminal unit does not receive the first identification signal and receives only the second identification signal, it recognizes that it is an intermediate terminal unit, and sends back downstream a token returned from upstream. Since the third terminal unit does not receive the identification signals, it recognizes that it is the lowest order terminal unit, and sends upstream a cell transmitted via a low data rate line according to a token returned from upstream.
