Inventor: REI UIRIAMU BOIRESU
IPC: G06F13/00
Filed: 1994-02-03
Abstract: PURPOSE: To guarantee that a session where current resource information should be set can be used, reduce network communication volume, and dynamically search for a target resource in the computer network. CONSTITUTION: The computer network wherein resources are dynamically searched for includes many cache server nodes 16A and 16B and network nodes 12A-12F and when a cache server node as an origination source receives a request from a node to be serviced, the cache server node searches Its local directory and sends the request to a substitute cache server node at need. If necessary information is not found In the local directory or at the substitute cache server node, the search request is broadcasted and communicated to all the network nodes in the network. When the result of the broadcast communication is inaffirmative, the request is sent to a selected gateway node 22 to continue to search an adjacent network.

Title: Cooling-fan controller in machinery
Inventor: KAJINO RYUJI
IPC: G03G15/00
Filed: 1992-01-27
Abstract: PURPOSE:To obtain a cooling fan, which can quickly meet change of load in a machine, by controlling the rotational speed of a cooling-fan motor according to the quantity of current flowing through a power supply part. CONSTITUTION:When voltage VX supplied from a power circuit is lower than a reference voltage Vvef 2, transistors 32, 32 are turned OFF and electric current flows through resistances 33, 33' for voltage drop so that the applied voltage of motor coils 27, 27' drops and the rotational speed of a cooling-fan motor is reduced. On the other hand, when the voltage VX exceeds the reference voltage Vvef 2, the transistors 32, 32' are turned on and the electric current does not flow through the resistances 33, 33' for voltage drop so that the applied voltage of the motor coils 27, 27' rises and the rotational speed of the cooling- fan motor is raised. Therefore, it is possible to quickly correspond to the change of load in a machine.

Title: Method and apparatus for avoidance of route-designation deadlock of packet
Inventor: HARISHI SESU
IPC: H04L12/56
Filed: 1995-01-30
Abstract: PURPOSE: To provide a device and method to establish path designation without a deadlock in a large scale 2-way multi-stage interconnecting cross point switch base packet network. CONSTITUTION: In the case of selecting a path included in a path table in a system, the entire network is effectively separated so as to inhibit specific paths to separate the system into prescribed divisions, e.g. to separate a packet traffic mostly flowing among nodes of a half part 503 of the system from a packet traffic flowing among nodes of the other half part 507 in the system. In order to extract paths of a packet passing among nodes in a common division of the system from this standpoint, paths including paths 522, 524 passing through the other system division are inhibited. The path inhibit as above is not caused in the selection of paths through which a packet is propagated among nodes in a plurality of the system divisions, e.g. nodes included in different halves of the system.
