Title: Method of time setting for system wherein master device is connected to slave device through packet circuit network having unstable transmission route
Inventor: ITO YUJI
IPC: G04G5/00
Filed: 2000-05-09
Abstract: PROBLEM TO BE SOLVED: To keep the deviation between the clock of a slave device and that of a master device within a desired time range in a system in which the master device and slave device are connected to each other through a circuit network using the D channel of the ISDN. SOLUTION: The master device M transmits a packet to the slave device S at decided timing by regarding the existing time as reference time. Upon receiving the reference time, the slave device S starts to count time from the received reference time and, at the same time, returns the received reference time to the master device M. Upon receiving the reference time from the slave device S, the master device M finds the transmitting time and, when the transmitting time is shorter than allowable time, instructs the slave device S to execute time correction. Consequently, the slave device S adopts the clock counting the time from the reference time as a new clock.

IPC: G07F19/00
Filed: 2000-05-11
Abstract: PROBLEM TO BE SOLVED: To store the paper moneys of plural denominations in the single paying-out stacker device of a paper money handling device and to pay out the stored paper moneys at need. SOLUTION: A paper money judged as a payable denomination is stored passing through a conveyer (2) into a paying-out stacker device (20). When a paying-out signal is received from a discrimination and conveyance control circuit (10), a (48) pays out the paper money of the payable denomination from the paying-out stacker device (20). Since a storage means stores the denominations of all paper moneys stored in the paying-out stacker device (20) and the order of storage, paying-out operation is repeated until the paper moneys of the required denomination are paid out for a required number. Besides, the paper moneys of the payable denomination are stored in the paying-out stacker device (20) and the paper moneys of the payable denomination can be speedily paid out from the paying-out stacker device (20) as needed.
