Title: Electronic file multicast distributing method and storage medium with electronic file multicast distribution program stored therein
Inventor: TAKASUGI KOICHI
IPC: H04L12/54
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To utilize limited communication capacity effectively and to distribute an electronic file while avoiding communication congestion by switching between distribution by a congestion avoidance type flooding method, when the movement quantity of a terminal is large or when a network is in an initial state and distribution using path information when the moving quantity of the terminal is small. SOLUTION: When distribution is made to plural terminals, each terminal is utilized as a repeater terminal. Since a congestion avoidance type flooding method selects an optional terminal among terminals, except a terminal to which distribution from a distribution destination terminal is already completed and performs relay distribution, it can flexibly corresponds to the change of physical relationships of terminals. Since a distribution method based on path information is a method, that designates a distribution path and performs distribution by using a routing table showing which inter-terminal is communicable, it can construct an optimum distribution path in comparison with the congestion avoidance type flooding method and improves distribution efficiency.

IPC: H04M1/57
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent the second reception of the same contents, without imposing the wasteful toll for calls to an opposite party by performing the control not to send the stored information, if the originator number of the calling side has been already stored in a toll saver object list of the opposite part who sent the information. SOLUTION: When the service information is updated, all toll saver object telephone numbers stored in a toll saver object list storage part 9 are deleted. When an operator of a FAX terminal performs a calling operation based on the notification of an originator number, an updated prescribed information can be selected and received. When the transmission is finished, a device controller 2 stores additionally the telephone number of an opposite party in the storage part 9. If the operator of the FAX terminal performs a calling operation before the service information is updated, the part 9 is retrieved for the received originator number. If a number matches the originator number is confirmed based on the result of the retrieval, no reception end signal is transmitted and a time-out is secured to reject the incoming.

Title: Vehicle suspension device
Inventor: MORITA TOSHIKI
IPC: B60G17/015
Filed: 1989-01-23
Abstract: PURPOSE:To prevent suspension control from becoming impossible due to an insufficient amount of an operating liquid by setting an upper limit value of an operating liquid flow rate according to the running condition of a vehicle and limiting the flow rate of the operating liquid which is controlled by a suspension control means. CONSTITUTION:An upper limit value setting means sets an upper limit value of an operating liquid flow rate according to the running status of a vehicle as detected by a running status detecting means, and the flow rate of an operating liquid in a cylinder device as regulated by a flow rate regulating means which is controlled by a suspension control means is limited so that it does not exceed the set upper limit value. This enables the flow rate of the operating liquid to be limited, or its consumption to be limited, before suspension control becomes impossible due to an insufficient amount of the operating liquid, thereby permitting continued suspension control.
