Patent JP-H07252054-A (JP)
Title: Observatory elevator
Inventor: SASAKI KIYOTAKA
IPC: B66B11/02
Filed: 1994-03-16
Abstract: PURPOSE:To make the whole or the part so as not to be seen from the outside by transmitting a light as a nematic liquid crystal comes to a condition of white suspensoid, dispersing the light, but in a state that the voltage is being impressed, the nematic liquid crystal comes to transparentness, respectively. CONSTITUTION:A liquid crystal device 5 is stuck to the lower half part of a transparent glass plate 4 of a window 3 of a gondola 1. This liquid crystal device 5 is made up of setting up a liquid crystal layer 8 in an interval between two transparent sheets where a pair of transparent electrodes 6 are formed. In a state that no voltage is impressed on an interval between these transparent electrodes 6, each nematic liquid crystal of the liquid crystal layer 8 is arranged so as to go along a wall surface in a capsule, and that since there is no rulability in a sense in this capsule, any outside light is dispersed around, an inner part of the car gondola is unable to be seen through. In a state that voltage is impressed on an interval between both these transparent electrodes 6, the nematic liquid crystals in the capsule is arranged toward an electric field, so that the outside light is transmitted through without being dispersed, and thus the inside of the gondola 1 is seeable through from the outside.

Title: Traffic congestion control system
Inventor: NAKAJIMA SEIICHI
IPC: H04M3/00
Filed: 1991-02-18
Abstract: PURPOSE:To easily operate the traffic congestion control system by detecting the congestion of a module, deciding a regulating amount as the number of distributed calls, announcing regulation information to an exchange or each node system and regulating the congestion. CONSTITUTION:When the exchange processing module in a node system 26 is congested, the maintenance/operation module of the system 26 transfers the congestion information of a regulation code/the number of distributed calls to the maintenance/operation modules of the respective node systems. The regulation code and the number of calls distributed to a node system 25 are transferred through a control line 8 to a congestion control part 21 of a maintenance/operation module 14. The control part 21 calculates the number of calls distributed to exchange processing modules 11-13 and transfers the regulation code and the number of distributed calls to a regulation circuit 22 when receiving the regulation code and the number of distributed calls as the regulation information. Based on this regulation information, the circuit 22 regulates the number of calls addressed to the regulation code so as to be less than the number of distributed calls. Thus, the congestion of a communication network can effectively be controlled.
