Title: Device, system, and method for issuing laissez-passer
Inventor: KUWAJIMA KAZUNARI
IPC: G07B1/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide the laissez-passer issue system which is improved in maintainability as to programs and data for passage charge calculation and adjusts fares with high reliability. SOLUTION: A center machine 3 divides a pass section by companies according to issue conditions from a ticket vending machine 5 and calculates the fare of this company by referring to fare information stored in a storage part in a center machine 3 as to the pass section of this company. For the pass section of another company, an inquiry is sent to the corresponding company through an inter-company network 2, the fare calculation result of the corresponding company is received, and the total fare is calculated by summing up the fare of this company and the fare of the corresponding company. The ticket issuing machine 5 receives the total fare and issues a pass commutating ticket. Even when the fare systems of other companies are changed, the fare information stored in the storage part of this company need not be altered.

Abstract: PURPOSE:To cancel an attraction force operated between a magnetic field generating member and a shaft by generating a magnetic field distributed symmetrically to the central axis of the shaft to the shaft by the member. CONSTITUTION:Magnetic field generating members 21a, 21b are disposed symmetrically to the central axis of a shaft 22 around the shaft 22 in the same shape and size, and its radial section is formed in a circular arc shape. The members 21a, 21b are so multi-polarized that N-poles and S-poles are alternately aligned at a predetermined pitch (t) in an axial direction. Here, the members 21a, 21b and the shaft 22 constitute a magnetic circuit in which a magnetic field is distributed symmetrically to the central axis of the shaft 22 in the axial direction of the shaft 22 as shown in the figure, as a stator of a motor. Thus, since the magnetic field is formed symmetrically to the central axis of the shaft, an attraction force operated between the member and the shaft is canceled, and hence deformation of the shaft can be prevented.
