Title: Travel time measuring system
Inventor: FUJIKAWA YOSHIMASA
IPC: G08G1/00
Filed: 1988-05-12
Abstract: PURPOSE:To improve the accuracy of travel time measurement by storing not only the passing time of a vehicle to be newly recognized in an upper stream spot but also the passing time of all the vehicles when plural vehicles, whose vehicle number is same as the vehicle to be recognized in a lower stream spot, are recognized in the upper stream spot. CONSTITUTION:A passing time table T is constituted to correspond to one vehicle number with a vehicle number N as an index, for example, to store the passing times of the three vehicles. Accordingly, when plural data of the same vehicle number are given in the passing of time, those numbers are successively stored. When the vehicle number data are received from a vehicle number recognizing terminal equipment 2b in the lower stream spot, a receiving time ta (passing time) is read and retrieval processing is executed for a passing time tb in the passing time table T with the vehicle number as the index. When the passing time tb is retrieved, the subtraction processing of ta-tb is executed and a travel time (t) is calculated. When the retrieved tb is one and the only one travel time (t) is obtained, the travel time (t) is stored as the optimum travel time as it is.

Abstract: PURPOSE:To prevent the generation of collision noise by lightening the shock in the closure of a door by installing a step difference on the contact surface of the contact part of at least one cushion, in an elevator door device having the contact part made of soft elastic material. CONSTITUTION:When doors 2 and 3 are to be closed, the contact surface 12b of a contact part 12 and the contact surface 14b of a contact part 14 contact. At this time, the contact surfaces 12d and 14d do not contact yet. Further, when the doors 2 and 3 are closed furthermore, the arcuate parts 12g and 14g deform, and also the doors 2 and 3 are decelerated. When the doors 2 and 3 are perfectly closed, each deformation of the arcuate parts 12g and 14g increases, and the contact surfaces 12d and 14d contact. Since the projection parts 12f and 14f contact and are perfecty closed after the doors 2 and 3 are decelerated, the shock noise in closure can be lightened by the deformations of the arcuate parts 12g and 14g and each elasticity of the projection parts 12f and 14f.
