Patent JP-S63162364-A (JP)
Title: Cable
Inventor: FEUZ FRITZ
IPC: B61B12/10
Filed: 1987-12-10
Abstract: The overhead cable transport installation possesses at each of the stations a transfer section between a disembarking section and an embarking section. At a still linear starting section of each transfer section there are provided driven wheels and at the linear end or terminal section of each transfer section there are likewise provided driven wheels. The driven wheels at the starting section are driven at a stepped greater rotational speed in relation to wheels located at the disembarking section, so that vehicles of the overhead cable transport installation arriving in the transfer section can be accelerated by the driven wheels engaging at friction shoes of the vehicle. A chain conveyor extends between the driven wheels of the starting section of the transfer section along the latter and transports the vehicles at an increased velocity and with a correspondingly greater mutual spacing from one another through curved portions of the transfer section. The driven wheels at the terminal section, which are driven by the wheels of the embarking section at a stepped greater rotational speed, again decelerates each vehicle prior to it arriving at the embarking section. At the disembarking section and the embarking section the vehicles thus can be moved at a lesser velocity and at minimum spacing or pitch from one another without vehicles colliding at the curved sections of the transfer section. The number of vehicles located at any given time at the transfer section can be maintained small.

Title: User group setting system in lan bridge system
Inventor: HISADA ISAO
IPC: H04L12/46
Filed: 1993-12-14
Abstract: PURPOSE:To provide a LAN bridge system capable of completely preventing unrequired packets among groups without using a router and plural exclusive buses in the case of performing grouping into plural independent groups for plural branch lines LAN. CONSTITUTION:In bridge circuits 12, 13, 14 and 15 for respectively housing the LANa1, LANan, LANb1 and LANbm, the group numbers of the respective housed LANs are set. The group numbers are added to the packets to be transmitted to the bus 11 at the time of transfer among the LANs inside the same group and filtering by the group numbers is performed before performing the filtering by MAC addresses which is a filtering function originally provided in the bridge circuits 12-15 for the received packet from the bus 11. Thus, multi- address packets and abnormal packets in the MAC layer of the LAN or the packets to be illegally communicated with the terminal of the other group are completely prevented since the group numbers are different.
