Title: Route control system
Inventor: TSUKAGOSHI MASAHITO
IPC: H04L45/586
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a highly expandable router configuration technology which flexibly copes with the need of line reinforcement of a router due to the large scale of a network. SOLUTION: A network information sharing means 14 is newly provided in a path calculation mechanism 20 of each router 12 constituting a cluster type router 11. The means 14 receives the updation notice of network information 16 collected by a routing protocol 15 and transmits this updation information as a network information notice packet 19 to the whole other routers 12 constituting the cluster type router 11. The network information sharing means 14 in a receiving destination router 12 notifies the contents of the received updation information to the routing protocol 15. The protocol 15 updates network information 16 belonging to itself based on the notified contents. Thus, network information 16 obtained from the entire routers existing outside the cluster type router 11 is shared by each router 12 and the cluster type router 11 is externally recognized as a single router.

Title: Centralized smoke stack with division plate
Inventor: TANIGAWA MASAYUKI
IPC: F23J13/00
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a centralized smoke stack with a division plate capable of preventing the occurrence of a large thermal stress to the division plate due to the thermal expansion difference between the stack body and the division plate. SOLUTION: This centralized smoke stack with a division plate is constituted in such a way that the inside of one cylindrical stack body is divided into a plurality of gas ducts 3a, 3b along the entire length of the stack in the height direction, and the respective gas ducts 3a, 3b are communicated with the respective exhaust gas sources. The width directional central part of the division plate 1 lying between the flat-plate-shaped parts 1b on both sides is made to be a bellows structure 1 so as to be expansible to the height direction. When the exhaust gas sources are operated, the temperature difference between the stack body and the division plate 1 is increased by the exhaust gas, and even if the thermal expansion difference between the stack body 2 and the division plate 1 is caused, this thermal expansion difference can be absorbed by the bellows structure 1a.  Thus, the causing of a large thermal stress in the division plate 1 can be prevented.

Title: Remote controller for vehicle load
Inventor: KOKUBU SADAO
IPC: B60R25/10
Filed: 1993-12-22
Abstract: PURPOSE:To surely prevent illicit act caused by intercept of a radio wave signal from a remote key through the reception synchronously with a transmission signal from the remote key with simple configuration. CONSTITUTION:Every time an operation button of a remote key is operated, a transmission circuit sends a count code (p) and an ID code C (k) corresponding thereto as a radio wave signal. The count code is formed by devising that the count value (k) is sequentially increased by '1' and N sets of different ID codes are cyclicly as signed. A receiver of a vehicle body stores similar code signals in its memory 37 and reads the received count code (p) and the designated count code P from the memory 37 upon the receipt of the code signal and reads the ID code corresponding to the received count code (p) in the case of count k>=K for the collation and provides an output of matching detection signal when they are matched and resets the designated count code into the original count code P in the case of dismatching. Even when the code signal is intercepted illicitly, since the receiver 6 does not accept the signal when the corresponding ID code is not set together with the advancement of the count code (p), the security is improved.
