摘要： A gateway (GW) for relaying a communication between a public telephone network and a routing server for managing use status of the GW and a network are provided on the internet. When a connection request is received, the GW issues a request to retrieve a route in which the costs are minimum and a necessary bandwidth can be reserved. The routing server retrieves the route of the minimum costs using the bandwidth reservation status of the internet and the partner's telephone number and notifies the request issued GW of the address of the partner GW. The costs at that time point may be notified to the user and the user selects whether the communication is performed or not. By managing the current connection information established by each GW, if a necessary bandwidth cannot be reserved, an audio compression ratio may be changed.

摘要： By adopting a method of requesting a band for each plurality of calls, or a method of requesting a band independently of origination or termination of a call, a method of reducing the frequency of origination of a call is provided. A first aspect may provide that a gate keeper requests security and release of a band not every call, but collectively for a plurality of calls, and the security and the release of a band are requested at frequency less than that of origination or termination of calls. A second aspect may provide that an estimated value of a time series change in necessary band is previously set in a gate keeper, and security and release of a band required for communication are requested depending on a time, but independently of origination and termination of a call.

摘要： An audio gateway is provided for receiving an internet relay request and a number called in a call from a telephone via the internet. An audio data gateway is selected using the number called, and relay operations are performed with the selected destination audio data gateway. The relay audio data is multiplexed for streams based on multiple relay requests having the same relay destination so that the relay audio data in these streams are multiplexed into a single relay stream.

摘要： In a digital copying machine, a ground in a document image is removed according to the type of document by referring to a histogram of reflectance data on a document image prepared for each line. A ground peak or a gradation level having the largest frequency in the histogram is determined. Further, frequencies are obtained in three windows appropriate for extracting characteristic quantities for ground, background and characters. A window for the ground quantity is determined according to the ground peak, and a ground range for removing the ground is determined by using the ground peak and the three frequencies. Then, the gradation data are corrected according to the ground range, and an image is formed on a sheet of paper according to the corrected gradation data. Thus, a ground can be removed by analyzing the histogram without a prescan.

摘要： A charging management server is informed of an ID number stored in an IC card, and a user charging table of the charging management server is read. A new user charging list is transmitted to an MFP. In the case where the MFP receives a cooperative job to be executed by a cooperative server, a sub charging list is generated. The generated new sub charging list is transmitted together with image data to the cooperative server. The cooperative server executes the job on the basis of charging a fee for the job. As the job is executed on the basis of charging, the sub charging list is updated. In parallel with the execution of the cooperative job by the cooperative server, the MFP can perform a normal job according to the charging list.

摘要： A method for testing a magnetic recording medium tests a magnetic recording medium provided on a non-magnetic substrate (1) with at least a magnetic layer (3) for surface characteristics by using a testing head possessing a heat sensitive element. The method starts from scanning the surface of the magnetic recording medium by using a testing head possessing a heat sensitive element. By this scanning, a signal component of low frequency originating in the swell of the surface of the magnetic recording medium is separated from the signal emitted from the testing head. The protrusion on the surface of the magnetic recording medium is detected from the signal of high frequency remaining after the separation.

摘要： An image reading apparatus according to the present invention allows the period of generation of a load signal NRD, the load value in counter circuits 21 and 31, and the comparative value in pulse generator circuits 22 and 32 to be changed corresponding to the multiplication rate of a PLL circuit 14. Accordingly, the pulse width and the phase length of the signals generated in signal generator circuits 12A and 12B are enhanced in the controllable accuracy by increasing the multiplication rate of the PLL circuit 14. Hence, even if the driving frequency is lowered, the pulse width and the phase length of the signals generated in signal generator circuits 12A and 12B can favorably be maintained in the controllable accuracy.
