Title: Sign device
Inventor: HATSUTA ISABUROU
IPC: G09F11/04
Filed: 1978-05-26
Abstract: PURPOSE:To secure the desired signing by driving via the single motor and the selective electromagnetic clutch action and along the guide groove the sign board produced by providing the notch reaching the center from the outer circumference along with the necessary passing gap secured through twisting of the notch. CONSTITUTION:The notches are drilled to reach center holes of circular sign boards 11-13 and then twisted evenly to shift the notch ends back and force, thus securing the necessary passing gap A. The outer circumference of board 11 is fixed to storing box 9, and the inner circumference of the board is fitted into spiral guide grooves 41-43 of central axis 4. Then mobile sign board 12 and 13 are given spiral movement along groove 42 and 43 by turning motor 40 forward backward. Thus board 12 and 13 pass through the gap of fixed sign board 11 and then stopped by limit switches 5-8. Meanwhile electromagnetic clutch  20 and 30 are actuated selectively, and as a result more than three different types of signs can be used by switching when necessary. Thus, a quick and accurate switching becomes possible for different signs with simple constitution.

IPC: G06Q30/06
Filed: 1989-03-17
Abstract: PURPOSE:To perform the service activities with high efficiency without retrieving the vacant seat information each time for each train to reach a destination and in order to secure the optimum waiting time by using a device which can input, store and calculates/compares the information. CONSTITUTION:Plural operation consoles 2 are connected via circuits to a CPU 1 which grasps the vacant seat information of all trains and all sections as well as the departure/arrival times of all trains. A display device 3 which shows the received vacant seat information is connected to each console 2 which can receive the vacant seat information on each corresponding section by transmitting the information on the entraining/alighting stations and the through stations. At the same time, a ticket issuing device 4 is also connected to the console 2 to print the due contents on the tickets and issue them when a ticket issuing instruction is given from the console 2 for the received vacant seat contents. Thus it is possible to perform the retrieving/selecting operations so as to secure the optimum waiting time in consideration of the transfer time and also to set the smallest distance traveled.
